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.

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.
