Resolving the “Cavity” between the East and West Coast.

Learn more about the blooming partnership of the US’s leading passive fire protection manufacturer and the Northwest’s top exterior technologies expert.

Exterior Cladding. Aluminum Panels. Rainscreen Systems. Façades. Recently, these terms have become popular in construction conversation, regardless of if you reside in the skyscrapers of Manhattan or the earthy, modern terrain of the Pacific Northwest’s cities. With its strong correlation to energy conservation and recently adopted energy codes, exterior cladding systems have been an attractive choice for construction development in cities, like NYC and Seattle.

But there’s one recurring issue in developing new façade-based structures – finding a fire-rated solution to accommodate stringent building regulations, life safety measures, and the benefits of energy efficiency. One of the most critical life safety hazards of a façade application is the interior cavity, designed to allow ventilation and energy efficiency, acts like an open chimney, in the unfortunate event of a fire. The void allows the fire to spread at an accelerated pace throughout the rest of the building – endangering lives and property. As a result, a variety of fireblocking solutions have been developed to reinforce this life safety hazard – however, when these solutions are implemented, they block off a majority of the cavity which greatly depreciates the level of energy efficiency, air circulation, and water drainage.

So, the question is “When there is no fire, why should the cavity be blocked”? In response, Tenmat has developed a variety of fireblocking solutions, which have been designed to enable the maintenance of an open ventilated cavity, preserve the energy conservation and building science benefits associated with cladding systems, while concurrently serving as a formidable fire barrier in the event of a building fire.

Here at Tenmat, we specialize in the development and manufacturing of intumescent technology – allowing us to meet the demands of construction professionals, based on application, thicknesses, shape, expansion rate and char formation after heat interaction. An intumescent is a material which reacts and expands aggressively when exposed to heat. In addition, this technology is designed to react and expand to fill all the gaps and changes in an opening, and therefore, can maintain a high-performance fire barrier for an extended duration. With this type of technology, it allows the construction application to shape a fireblocking solution to accommodate its demands rather than the opposing. Furthermore, Tenmat has worked closely with ventilated rainscreen professionals and building code officials to develop the optimal intumescent-composed fireblocking solutions for façade application.

Composed with a rigid, high expansion intumescent, Tenmat’s FF102/50 Intumescent Fire Block are used as fire blocks at slab lines, fire blocks around windows and as fire blocks at changes in occupancy (horizontally and/or vertically) and for larger openings, Tenmat’s VFB+ Ventilated Fire Barrier is composed of a high expansion intumescent seal fixed to TENMAT High Density Mineral Wool. Both of these intumescent solutions are designed to maintain the open, ventilated cavity in normal conditions, but will expand to seal off the cavity gap when exposed to heat. Therefore, the FF102/50 Intumescent Fire Block and the VFB+ Rainscreen Fireblock allow construction professionals to receive the full benefits of façade systems, while maintaining the appropriate level of life safety, in the event of a fire.

Discover how passive fire protection for LED downlights plays a key role in protecting our communities.

Where It Begins.

Energy efficiency, aesthetics, and increased life longevity are some of the key reasons why LED wafer downlights have been setting the lighting standards in modern construction practices. From constructing new Type V-A multifamily complexes to upgrading the current lighting system in a boutique hotel, LED downlights have the ability to offer easy installation for contractors, and the aesthetics for architects and developers – the ultimate combo. In addition to the previously mentioned applications, LED downlights can often be found in the following applications:

  • Commercial Spaces: Includes shopping malls, mixed-use buildings, local boutiques.
  • Residential Buildings: Includes multi-family complexes, student housing.
  • Hospitality Spaces: Includes hotels, motels, lodges, inns.

 

With its ability to be installed in renovation jobs and new construction projects, it is critical to ensure that our current and future communities are fully protected from life safety hazards, such as unprotected ceiling openings.

Look up at your ceiling. It’s important.

Frequently, unprotected ceiling openings are one of the most common life safety hazards found in modern construction applications. When a fire-rated ceiling assembly is penetrated by a recessed fixture, such as a LED wafer, the integrity of the ceiling is compromised. In the event of a fire outbreak, the recessed fixtures disintegrate after several minutes, allowing a clear pathway for smoke and flames to maneuver to the next level of an infrastructure.
As a result, the International Code Council has established a building code requirement to ensure that this life safety hazard is properly resolved within our communities. For reference, Section 714.5.2 of the 2021 IBC states:

“Where floor/ceiling assemblies are quired to have a fire-resistance rating, recessed fixtures shall be installed such that the required fire resistance will not be reduced.”

In addition, it is essential to point out that LED wafers are being installed in both existing infrastructures and new construction. Therefore, it is critical to ensure that the unprotected ceiling openings are properly fire-rated, no matter if the infrastructure is previously existing or currently being built.

Exploring Your Options.

As the popularity of LED downlights reaches new heights in modern construction, it was critical that a proper fire-rated solution was developed. One of the recent trending solutions are “fire-rated” lights. These solutions are budget-friendly and offer quick, easy installation for on-site contractors. However, a huge misconception about these solutions is because they are composed of metal – they automatically have a fire-resistance rating for applications where fire-resistance rated assemblies are required. However, this is a false assumption. Even though metal itself offers some firestopping properties – it is a poor insulator and does not mean that a metal-based solution qualifies as a fire-rated solution. In order for any solution to claim they are fire-rated, it needs to be tested and approved by a third-party laboratory.

Another method of properly firestopping a LED “pancake” light is fire-rated drywall boxes. This firestopping method is where gypsum wallboards surround the LED wafers; however, there are several cons of this practice. Fire-rated drywall boxes are known to be associated with high labor savings, which can increase the cost of installation beyond budget limits. One of the main causes for high installation costs is this solution’s inability to be retrofitted into a pre-existing ceiling – meaning the pre-existing ceiling would need to be deconstructed prior to the installation of these solutions. In addition to its high labor costs, fire-rated boxes are not properly fire tested and certified – which defeats the purpose of installing proper passive fire protection measures.

Spec the Best, Specify Tenmat.

Now, all of the previously listed solutions don’t exactly check off all the boxes – so, the pressing question is “Are there any solutions that can check off all the preferred features of a firestopping solution?”. To answer your question, let us introduce you to – Tenmat’s FF109-200 and FF109-250, 1 Hour Fire Rated LED Downlight Covers. Composed with the latest intumescent technology, the FF109-200 and 250 are able to stop heat and flames from spreading to other parts of a building for up to 60 minutes.

Learn More About the Ins and Outs of Passive Fire Protection in the Vast Spectrum of Construction Applications.

In today’s construction landscape, construction professionals are constantly experiencing building code adoptions. One of the key reasons for the consistency in building code updates is the advocacy for up-to-date life safety measures for traditional and modern construction applications. Therefore, the use of passive fire protection has become quite popular on active construction sites and new construction infrastructures; however, there are still questions surrounding this form of life hazard. Here at Tenmat, we understand the monetary costs of a failed building inspection and the liability of installing a falsified fire-rated solution. In this blog, we will be answering some of the most important and frequently asked questions regarding passive fire protection. Well, there’s no time to waste when it comes to safety – let’s get started!

“I just failed a building inspection. The electrical inspector stated that my fire-resistance rated ceilings have been compromised, due to installation of recessed can lights. Why is my ceiling compromised? What building codes are associated with this situation? Are there any available solutions?”

Municipalities across the United States – through adoption of the International Building Code – require fire-resistance-rated ceilings for certain commercial, industrial, institutional, residential, and other occupancies buildings. When a fire-resistance rated ceiling assembly is penetrated by a fixture, such as recessed can light, LED downlight, or troffer luminaire, the ceiling is now compromised. The reason being is when there is a fire outbreak, the flames and heat disintegrate the fixture within several minutes. Once the fixture is non-existent, the ceiling opening no longer works as a barrier to protect flames, heat, and smoke from traveling throughout the rest of the building. As a result, building code professionals have established a requirement for these unprotected ceiling openings. For reference, in section 714.5.2 of the 2021 IBC: “Where floor/ceiling assemblies are required to have a fire-resistance rating, recessed fixtures shall be installed such that the required fire resistance will not be reduced.” To resolve this issue, there are various passive fire protection solutions that accommodate to these life safety hazards, which we will learn more about in this blog.

“I am specifying passive fire protection solutions in a new-construction multifamily complex. I saw various forms of passive fire protection solutions; but I know not all solutions are properly fire-tested. How do I know which solutions are properly fire-tested?”

One of the simplest ways to confirm that a solution is properly fire tested is to visit the manufacturer’s website, and review the solution’s listing, test report, or certification. If you are unable to locate the certification or questioning the authenticity of the certification, you can visit one of the national and international acclaimed independent third-party testing laboratories, such as Underwriter Laboratories (UL) or Intertek, and verify the solution’s testing. If you are unable to find the proper certification, the “fire-rated solution” is not properly fire tested.

“Currently, I am looking for a non-standard passive fire protection solution. How do I accommodate this life safety hazard with the correct passive fire protection solution?”

With the rapid growth of modern construction practices, new life safety hazards spring up on a regular basis. In response, passive fire protection manufacturers are expected to formulate the proper solutions for these hazards; however, modern construction practices are accelerating more rapidly than the evolution of passive fire protection solutions. Here at Tenmat, we understand that all life safety hazards need to be fitted with the proper solution. With our on-site research and development team, we have the accessibility to work one-on-one with construction and building professionals to develop non-standard passive fire protection solutions and test them. Sounds like a current problem you are facing? Contact us at +1-800-821-3436 to learn more about the opportunities Tenmat has to offer you and your team.

“When exploring for passive fire protection solutions, I came across a variety of fire-rated materials. What are the differences between intumescent, mineral wool, fire-rated drywall, and metal solutions?”

With the growing demand for passive fire protection solutions, the availability of different fire-rated materials has significantly increased. One of the traditional firestopping materials is “fire-resistant” gypsum wallboard. This material tends to result in a highly labor-intensive installation, which may increase the cost of installation beyond budget limits. Another commonly used material is metal; however, metal is not very flexible, in terms of aesthetic and product variations. In addition to its lack of flexibility, metal is also known to be a poor insulator and will not sufficiently stop the fire’s heat transfer. In contrast, mineral wool and intumescent are known to be ideal for firestopping applications, due to their flexible nature and their adaptability to produce various forms of firestopping solutions.

Even though the above materials are associated with firestopping capabilities, it DOES NOT mean that the final product offers the same level of firestopping. Therefore, it is critical to review the manufacturer’s testing certification to verify that a solution is properly fire tested.

“I know unprotected ceiling openings caused by recessed lights need to be properly fire-rated. But, what about other recessed fixtures, such as in-ceiling loudspeakers?”

Yes, in-ceiling loudspeakers need to be properly fire-rated in fire-resistance rated ceiling/floor assemblies. In addition to the 2021 IBC Section 714.5.2, the 2017 NEC (National Electrical Code) requires in Section 640.25, “Loudspeakers installed in a fire-resistance rated partition, wall or ceiling shall be listed in an enclosure or recess that maintains the fire resistance rating”. Even though this life safety hazard has been present for several years, there are very few optimal solutions to rectify this hazard. As a direct response to this building code, Tenmat has formulated the optimal fire-rated solution, the FF109-FRSC, a 1 Hour Fire-Rated Speaker Cover. Composed with the latest intumescent technology, the FF109-FRSC has the ability to contain flames, smoke, and heat for 60 minutes – allowing additional time for evacuation of the blazed structure. As an added bonus, the sound absorbing properties of the proprietary intumescent material enhances the acoustic performance and protection of the installed loudspeaker. Learn more about the key benefits of installing Tenmat’s FF109-FRSC by visiting this website.

“I noticed that there a variety of passive fire protection solutions on the market. What are the advantages and disadvantages of each variation of fire-rated solutions?”

There are several different solutions for fire-resistance rated ceiling membrane applications with a diverse range of prices, approvals from third-party testing facilities, and product designs. One of the recent trending solutions are “fire-rated” lights. These solutions are budget-friendly and offer quick, easy installation for on-site contractors. However, a huge misconception about these solutions is because they are composed of metal – they are UL-classified and are suitable for applications where fire-resistance is required. However, this is false. Even though, metal itself, offers some firestopping properties – it is a poor insulator and does not mean that a metal-based solution qualifies as a fire-rated solution. In order for any solution to claim they are fire-rated, it needs to be tested and approved by a third-party laboratory.

One of the more traditional firestopping methods is fire-rated drywall boxes. This firestopping method is where gypsum wallboard surrounds the recessed fixtures; however, there are several cons of this practice. Dry-wall boxes are known to be very labor intensive and may increase the cost of installation beyond budget limits, in addition to possibly not having a proper fire-resistance rating.

Finally, a popular intumescent firestopping solution, which is properly fire-tested by a third-party laboratory (UL and Intertek), are Tenmat’s Fire-Rated Enclosures for in-ceiling fixtures. Tenmat covers are suitable for recessed can lights, LED downlights, troffer luminaires, and in-ceiling loudspeakers – applicable to various sizes and systems.

Beyond Books: A Lesson in Safety – Unveiling the Significance of Passive Fire Protection in Educational Environments.

Exploring the Vital Applications and Measures to Ensure Life Safety in K12 Schools, Colleges, and Universities is Met.

Fires in Focus: The Critical Demand for Passive Fire Protection in Educational Facilities

In the ever-expanding landscape of educational institutions, ensuring the safety of students, professors, administration, and additional staff is crucial. Whether you are renovating lighting fixtures in elementary schools or constructing a new dormitory for an expanding university campus, it is prominent to ensure passive fire protection measures are properly implemented to protect the lives and property within the “incubators” of our current and future generations.

Beyond the Flames: Demystifying Passive Fire Protection

Passive fire protection is a comprehensive defense strategy vital to securing educational structures from the devasting consequences of fire outbreaks. Unlike active fire protection systems that require human intervention, passive measures are inherently built into the architecture to automatically respond in the event of a fire. These measures include the incorporation of fire-resistant materials, specialized doors, and enclosures designed to contain and slow down flame and smoke progression. Therefore, passive fire protection acts as a proactive solution rather than reactive solutions – which caters to the critical element of time.

One of the primary and most profound significances of passive fire protection is its capacity to save lives. In the unfortunate event of a fire outbreak, these measures form a crucial barrier, impeding the progression of flames and smoke. This containment not only prevents the rapid escalation of the fire but also provides additional time for the execution of evacuation procedures. In educational settings, where the safety of students and staff is paramount, these vital moments can make a life-altering difference. In the chaotic atmosphere of a fire, every second counts, underscoring the imperative role that passive fire protection plays in enhancing the overall safety and resilience of educational environments.

Guardians of Learning: Identifying Key Areas for Passive Fire Protection

One of the primary contributors to the rapid expansion of a fire outbreak lies in unprotected ceiling openings, particularly those caused by recessed light fixtures in fire-resistance rated ceiling/floor assemblies. These openings create avenues for the swift dissemination of flames and smoke throughout the structure, posing a serious threat to the safety of its occupants. The implementation of passive fire protection solutions is crucial in mitigating this risk. A fire-rated enclosure, designed with materials like fire-rated drywall, mineral wool, or intumescent technology, acts as a safeguard by compartmentalizing the smoke and flames.

In addition to the vulnerability posed by unprotected ceiling openings from recessed light fixtures, in-ceiling loudspeakers also contribute to the rapid spread of fire outbreaks. Given the essential role of Public Address (PA) systems in large facilities like K12 schools and university learning centers, in-ceiling loudspeakers are prevalent in academic buildings. However, the integration of audio-visual (A/V) technology introduces additional pathways for flames, heat, and smoke to traverse. Therefore, it becomes imperative to install passive fire protection solutions in these applications to fortify the fire resilience of such structures.

Apart from the risk associated with unprotected ceiling openings from recessed lights and in-ceiling loudspeakers in fire-rated ceiling/floor assemblies, another concern arises from through-penetration openings caused by cables and wires. These openings create potential channels for the uncontrolled passenger of fire, compromising the integrity of firestopping barriers. To address this hazard, the installation of passive fire protection measures, including fire-rated plugs, blocks, foams, and sealants designed to stop flames and smoke, is becoming crucial. These solutions eliminate the smallest of pathways for flames and smoke, allowing for occupants to have a larger time frame to occupants.

In-ceiling loudspeakers seamlessly integrate into various construction practices, finding their place in residential home cinemas, shopping malls, office buildings, university lecture halls, and a wide range of diverse applications.

Whether you are installing recessed speakers in your local high school’s new auditorium or upgrading your at-home theater, it is important to acknowledge the safety hazard of installing these products into various ceiling structures. Once installed in a fire-resistance rated ceiling assembly, the integrity of the ceiling has been compromised. If these openings remain unprotected, flames, smoke, and heat will be able to spread at a rapid rate, putting lives and property at risk. As a result, passive fire protection measures have been implemented through various building code requirements – requiring contractors to install a fire–rated solution or housing to contain the fire for a long time.

In addition to this requirement, when installing in-ceiling loudspeakers, you also may need to be concerned about the sound dampening capabilities of the fire-rated solution. In states, such as California, have adopted a minimum level of sound isolation across party walls and floor/ceiling in hotels, condominiums, dormitories, office buildings, and multi-family complexes. Therefore, developing a solution that can meet both building requirements is ideal for labor and cost savings.

At Tenmat, we are committed to developing the latest fireblocking technology and catering to the demands of A/V installers and electrical contractors. A blend of sound isolation, easy installation, and passive fire protection, TENMAT created the FF109-FRSC, a one-hour fire rated speaker cover. The FF109-FRSC 1 Hour Fire Rated Speaker is a dome-shaped intumescent enclosure which has been specifically designed to help maintain the integrity of fire-resistance rated ceiling/floor assemblies for one hour when penetrated by in-ceiling speakers. In addition, the sound absorbing properties of the propitiatory intumescent material enhance the acoustic performance of the speaker’s housing – allowing for a level of sound isolation.

With its adaptability and flexibility, Tenmat’s intumescent materials offer fireblocking and sound isolation properties to a multitude of applications.

Tenmat Joins RAiNA: Building a Stronger Future for Rainscreen Technology

Tenmat becomes a member of the RAiNA, the leading authority on rainscreen design and construction

Tenmat, a leading manufacturer of advanced intumescent fire block solutions for ventilated rainscreen systems, is excited to announce its membership in the Rainscreen Association of North America (RAiNA).

Modern constructions often require external cladding and rain screens be held away from the building structure to allow ventilation and improve the building energy efficiency. This resulting cavity creates a serious fire protection threat to structures and people. The void can act as an open chimney and allows the fire to spread quicky around the building. Modern building codes, such as the 2022 New York City Building Code, have identified this issue and are now requiring fireblocking in these concealed draft openings behind the cladding.

In response, Tenmat has developed a quick acting intumescent fire block for ventilated rainscreen and cladding systems, the FF102/50. The Innovative FF102/50 Fire Blocks were designed to allow the benefits of the practice of cladding systems, such as energy conservation, air circulation, and moisture dissipation; however, eliminating the “chimney effect”.

In recent events, Tenmat’s FF102/50 had successfully passed the NFPA285 test. The FF102/50 fire block was expertly deployed around window openings and at all slab lines, meticulously adhering to the position requirements for fireblocking material in the updated building code. Under normal conditions, Tenmat’s rigid and highly expansive intumescent fire block enables the maintenance of an open ventilated cavity, preserving the energy conservation and building science benefits associated with cladding systems, while concurrently serving as a formidable fire barrier in the event of a building fire.

With joining the Rainscreen Association of North America, Tenmat is enthusiastic to educate other fellow members of this fire hazard in rainscreen systems and the potential solutions to help protect lives and property, in the unfortunate event of a fire.

Passive Fire Protection 101 – Don’t Fail Building Inspections

Don’t Fail Building Inspections

Knowledge about the regulations regarding recessed lights in fire-resistance-rated ceilings can help avoid costly mistakes and legal actions. There seems to be a great deal of confusion about what exactly fire-resistance-rating means, where it is applicable, and the solutions available to meet the building code requirements.

The widespread adoption and understanding of codes requiring continuity of fire-resistance-rated assemblies throughout the world has made this subject more and more relevant to contractors, builders, code officials, architects, building owners and managers, and homeowners. But instead of decreasing confusion over the issue, continuous changes in state code adoption legislation and increased demand for fire-resistance-rated, code compliant products and systems have far outpaced the availability of education on the topic.

What does fire-resistance-rating actually mean?

A fire-resistance-rating typically states the duration for which a building element or an assemblage of materials can withstand a standard fire-resistance exposure test. A fire-resistance-rating is usually given to an assembly consisting of various building materials that can resist the exposure of a standardized fire exposure for a set amount of time, or it may contain a variety of other criteria involving other evidence of functionality or fitness for purpose.
Fire-resistance-ratings were developed to evaluate the performance of building elements and assemblies during an intense fire exposure and can be applied to wall, floor, or roof systems, also known as horizontal assemblies.

How do you properly fire rate a ceiling?

The 2021 version of the International Building Code addresses this issue explicitly in section 714.5.2, Membrane Penetrations:

714.5.2 Membrane penetrations. Penetrations of membranes that are part of a horizontal assembly shall comply with Section 714.5.1.1 or 714.5.1.2. Where floor/ceiling assemblies are required to have a fire-resistance rating, recessed fixtures shall be installed such that the required fire resistance will not be reduced.

In addition, this section of the Code includes several exceptions. The following exception applies to listed luminaries (light fixtures). Please refer to the entire Code language and exceptions which apply to other types of membrane penetrations.
Exceptions:

8. Ceiling membrane penetrations by listed luminaires (light fixtures) or by luminaires protected with listed materials, which have been tested for use in fire-resistance-rated assemblies and are installed in accordance with the instructions included in the listing.

To meet this membrane protection code requirement, the ceiling must serve as an unbroken, continuous fire-resistance-rated horizontal assembly for a specific period of time.

In fire-resistance-rated wallboard applications, a typical assembly might have one layer of gypsum wallboard used on the underside of a floor/ceiling assembly that has been tested in accordance with the ASTM E 119 or UL 263 requirements for the hourly fire-resistance-rated assembly. In some cases, this could be a 1-hour fire-resistance-rated assembly; however, the time requirement may be greater than 1-hour, depending on the occupancy, height, and area of the building.

Use solutions that work best for your project and timeline.

There are several different solutions for fire-resistance-rated ceiling membrane applications with a diverse range of prices, approvals gained from fire-testing, and complexity. A common solution is prefabricated Fire-Resistance-Rated Light Fixtures, which have a variety of proven fire-resistance testing but are also the costliest choice
To avoid using these expensive lights, many construct boxes made from gypsum wallboard to surround the lighting fixture. This is very labor-intensive and may increase the cost of installation beyond budget limits, in addition to possibly not having a fire-resistance-rating.

Metal enclosures are also becoming an increasingly popular choice in the fire-resistance-rating dilemma. However, these are not UL-classified as a fire-resistance-rated assembly and so are not suitable for applications where fire-resistance is required.
A popular solution that is UL-classified are Fire-Resistance-Rated Light Covers. These covers are suitable for various recessed light fixture sizes and luminaires, and they comply with building code requirements for continuous fire-resistance in horizontal assemblies.

The covers are widely accepted by code officials throughout the entire United States, and possibly in other countries as well. One- and two-hour Fire-Resistance-Rated Light Covers are available from a variety of manufacturers at several different price points. They are proven to act as a suitable fire-resistance-rated horizontal assembly when called upon by fire and smoke.

Tenmat’s Fire Rated Recessed Light Covers are the solutions you’re looking for.

TENMAT fire rated enclosures and firestopping products have been designed to meet the building code and to help maintain the integrity of fire-resistance rated ceilings when penetrated by recessed lights, LED luminaires, fluorescent fixtures or in-ceiling loudspeakers or walls when penetrated by wires, cables, pipes or mixed penetrations. Tenmat’s unique design gives the architect, specifier and installer more freedom in fixture selection as the covers are suited to a wide range of recessed fixtures.

The flexible and lightweight nature of the covers makes installation quick and easy, reduces the stress put on the ceiling and significantly reduces labor costs compared to standard dry-walled box constructions. The high expansion and insulating properties of the cover ensures that both flames spread, and heat transmission are stopped for 60 minutes.
