Meet the Ford of the Façades Industry: Intumescent Fire Blocks for Ventilated Rainscreen Assemblies.

Discover why intumescent technology is the prime fireblocking solution for the growing states of Michigan and Indiana.

Detroit. Indianapolis. Fort Wayne. Ann Arbor. Grand Rapids. All of these major Great Lake cities have three things in common: they 1) are rapidly expanding, due to population growth, 2) have adopted the construction application of ventilated rainscreen systems, and 3) have been required to eliminate the chimney effect in these open-state cavities.

In modern ventilated rainscreen applications, its interior gap allows for a multitude of sustainability benefits, such as proper air circulation and moisture dissipation; however, this open cavity is a highly accessible route for heat, flames and smoke to rapidly travel throughout the building, both horizontally and vertically. With this form of accessibility, a fire outbreak can consume an entire building in a short time span – permitting individuals from having a sufficient evacuation timeframe.

To resolve this critical hazard, both building code officials and passive fire protection manufacturers have partnered together to formulate effective solutions to block off the pathway of the fire. However, one of the major disadvantages of these solutions is that it’s positioning greatly affects the functionality purposes of a ventilated rainscreen system.  Traditionally, this technology seals off the cavity opening entirely, and when a fire occurs, it is compartmentalized by the technology. However, with the technology sealing off parts of the ‘open state’ cavity – the advantages of proper air circulation and moisture dissipation are nearly diminished.

Engineered with the latest in intumescent technology, Tenmat’s Ventilated Fire Blocks and Barriers are designed to allow for the full efficiency of air circulation and moisture dissipation in an open cavity – while providing the appropriate level of fireblocking. Intumescent technology is a material which reacts and expands aggressively when exposed to heat – allowing for gaps and changes in an opening – such as a ‘open state’ cavity in a ventilated rainscreen assembly. With this technology, we designed our fireblocking solutions to be compacted to the level, where it allows for the proper functionality of an open-air’ cavity and when activated by heat, expands far enough to seal off the entire cavity.

Finding the Perfect Fit in Façades.

Tenmat announces partnership with Midwest Architectural Rep, Blue Line Building Products.

With the recent surge of US energy conservation code requirements, a vast amount of new construction projects have adopted the practice of ventilated rainscreen systems into their developing projects. With its wide range of energy efficient capabilities, ventilated rainscreen assemblies are an attractive, newly found construction practice – which has been rapidly adopted from all over the country. Unfortunately, this construction method produces a critical life safety hazard – the chimney effect.

In normal conditions, the ‘open state’ cavity allows for the structure to have proper ventilation and improvement in the overall building’s energy efficiency. However, in the event of a fire outbreak, this open void allows for the heat, flames, and smoke to travel vertically and horizontally throughout the structure – at an accelerated pace. As a result, recent building code adoptions have implemented a fireblocking requirement to eliminate this life safety hazard – protecting the lives and properties within our communities.

As a response, numerous forms of fireblocking technology have been developed to meet recent building code adoptions and resolve the issue of the chimney effect. However, a majority of these fireblocking solutions seal off the internal cavity of the assembly– which diminishes air ventilation, increases moisture dissipation, and decreases the building’s overall energy efficiency.

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.

In the effort to protect growing communities and offer the latest in fireblocking technology, such as the Midwest, Tenmat has partnered with the architectural representative, Blue Line Building Products. With their dedication to finding the right product for the right applications, Blue Line BP offers the highest quality building envelope products and design-assist services in the rapidly growing Midwest.

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.

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.
