Explore how Tenmat’s Advanced Intumescent Solutions and Materials have shaped the future of passive fire protection in modern-day construction.

As of 2024, the United States is home to 19,479 cities, towns, and villages – each containing an even greater number of communities. Now, each community can contain a multitude of different structures. Some contain bustling shopping malls, others are developing new multi-family complexes, certain ones include a wide range of various healthcare centers, and a number of them hold all the above and more.

Not one community is the exact same. But every community wants to protect the people and property within theirs. Therefore, whenever a community is getting a “face lift” or expanding internally or externally, life safety is the No.1 priority of the growing community.

To uphold this priority, communities need to prepare its redeveloping or new-construction buildings to withstand all potential disasters – especially the unexcepted ones.

The Beginning of Passive Fire Protection

Fire outbreaks have always been known to negatively impacted communities, especially when it comes to protecting properties and the lives within them. Over hundreds of years, countless safety measures have been put into place to fight off the potential damage of fires. From fire extinguishers to automated sprinkler systems, building code officials, construction professionals, and community members believed that they all their bases were covered.

However, this assumption was incorrect. Before 2006, unprotected openings were an unrecognized life safety hazard in many communities. These openings included openings created from recessed lights, in-ceiling loudspeakers, wires, cables, etc. Without being properly reinforced, these openings acted as a catalyst for the fire. Without these openings being improperly fire-rated, heat, smoke, and flames can spread rapidly throughout the building – endangering the integrity of the building and the lives of its occupants.

As a result of this discovery, the 2006 International Building Code adopted several building codes which required construction professionals to reinstate the fire-resistance rating of a wall, ceiling, or floor assembly. This is where we introduce the concept of passive fire protection.

Passive Fire Protection is the system which slows or prevents the spread of fire within a building – utilizing fire-rated materials and solutions to achieve this.  This system works by using fire-rated solutions, such as intumescent recessed light covers, to contain fire, heat, and smoke, by limiting heat and fire spread to a single compartment within the building.

Causing fires to become smaller and contained, passive fire protection (PFP) systems have the ability to increase the response time for first responders and provide additional evacuation time for the building’s occupants.

Tenmat’s POV: The Importance of Passive Fire Protection

Following the building code adoptions, construction professionals were seeking PFP solutions and materials that can resolve the unprotected openings within their design details. However, construction professionals struggled to find a fire-rated solution, which has been

  1. Properly tested and certified by an accredited third-party testing laboratory,
  2. Fitted to meet the design requirements of the application, and
  3. Engineered to be easily installed into a wide range of building types.

Dedicated to protecting the safety of present and future communities, Tenmat developed an adaptable form of passive fire protection technology, intumescents. With the release of this technology, construction professionals were now able to meet local building codes while simultaneously fulfilling their design concepts.

Through our manufacturing capability to produce intumescents, which offer various expansion rates and char production, Tenmat’s Advanced Intumescents can protect a wide range of unprotected openings.

With this versatility, our intumescents can be specified into a diverse range of unprotected openings. From ventilated air cavities in a rainscreen assembly to recessed fixtures in a fire-rated ceiling assembly, Tenmat’s Advanced Intumescent Materials and Solutions can reinforce the integrity of these fire-resistance rated assemblies.

Enforcing Life Safety + Passive Fire Protection

Even though, Tenmat’s Solutions and Materials evolved alongside modern construction – the visibility of passive fire protection in modern construction remains on the lower side. Admittedly, this lack of visibility remains valid, due to the extensive, ongoing list of safety measures code officials and construction professionals are required to memorize and specify.

On top of curating our wide range of Advanced Intumescent Solutions and Materials, Tenmat is dedicated to educating local building code officials and construction professionals about unprotected openings in numerous building types. To encourage these individuals to gain more knowledge about these life safety hazards, we offer free 1-1 educational webinars for anyone who may be interested.

“Re-Wiring” Your Brain on Through-Penetration PFP.

Red text reads “Passive Fire Protection for Through-Penetration Applications” above fire safety products and a brick.

Discover how properly fire-rated through-penetration openings play a pivotal role in protecting our current and future communities.

Passive Fire Protection in Modern Construction

“Are these ceiling openings properly fire rated?” “Do I need a one-hour or two-hour fire rating for this recessed can light?” “Are you installing intumescent material into your ventilated rainscreen system?” Over the past several construction seasons, these various questions have been asked on active job sites and in planning rooms: however, all of these questions circle back to one popular topic – passive fire protection. With its prominent impact on life safety, passive fire protection has overtaken the construction landscape by storm – especially with unprotected openings. Often, we associate unprotected openings within ceiling assemblies, which have been penetrated by recessed can lights, LED downlights, troffer luminaires and/or in-ceiling loudspeakers. However, let’s think smaller. Let’s talk about through-penetration openings in fire-resistance rated assemblies.

Thinking it “Through”ly.

With the surge of technology, new construction infrastructures are home to hundreds of running wires, cables, and pipes running through the wall, ceilings, and walls of these buildings. As a result, when these fire-resistance rated assemblies are penetrated by one of these elements, the assembly is compromised – regardless of how small the magnitude of the opening. Even though these penetrations tend be relatively small, it still creates a pathway for heat, smoke, and flames to rapidly consume the infrastructure of the building. As a response to this life safety hazard, the IBC (International Building Code) regulated that proper firestopping measures are required for through-penetration applications. For a reference, in Section 714.3.1.2 of the 2012 IBC, it states,

“Through penetrations shall be protected by an approved penetration firestop system installed as tested in accordance with ASTM E814 or UL 1479, with a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water and shall have an F rating of not less than the required fire-resistance rating of the wall penetrated.”

Identifying Where Proper Firestopping is Required.

As this building code adapts to the modern construction scene, it is critical to educate construction professionals on where this code will apply. With 100% of US buildings containing at least one wire, cable, or pipe – this requirement is universal. However, here are some common construction practices that will potentially require firestopping solutions for through-penetration openings:

  • Multi-Family
  • Data Storage Facilities
  • Modular
  • Façades
  • Healthcare (Hospitals, Rehabilitation Centers, Medical Centers)
  • Hospitality
  • Commercial
  • Industrial
