FireStop TB

FireStopTB™ is a high top quality RockWool mineral fiber developed in a granular form. This product is fireproof, soundproof, moisture resistant, rustproof, non-deteriorating, mildew-proof, vermin-proof and is also the “greenest” insulation on earth today. Used over Plastic Insulation, FireStopTB™, is a new spray applied RockWool insulation with the addition of an adhesive, and is classified as a thermal barrier over foam plastic insulation. FireStopTB™ ensures open fire protection but it also offers you excellent sound absorption with a one of the highest NRC and STC ratings in the industry.

Premium quality mineral fibers created in a granular form that enables it to be sprayed onto open or closed cell foam with the addition of FireStop TB™ Adhesive to provide a 15 minute rated thermal barrier. The specially formulated blend of mineral fiber along with the introduction of adhesive at the point of installation allows for it to be blown directly on the foam substrate. Analyzed relative to NFPA 275 Standard Technique of Fire Tests for the Evaluation of Energy Barriers Used Over Foam Plastic Insulation – both Parts 1 and 2. Typically the maximum depth that can be sprayed overhead is 7” in a incline and 5” on a flat. FireStop TB™ must be blown to at least a depth of 1-1/2”.

FireStop TB™ provides a true thermal buffer over spray foam padding. FireStop TB™ has a tested R-Value of 4. 14 per inch. FireStop TB™ is classified by NON-Cumbustible per ASTM E-136. With a flame propagate of 5 and a smoke development of zero FireStop TB™ not only protects from flames but smoke inhalation as well.

Unlike every other Thermal Buffer, FireStopTB adds a Noise Absorbing Acoustical Layer that can be tinted to any color using ProCoustic Coating.

When most fires start in the attic and it if happens to take place at night, a great intumescent ignition barrier really does a give a house owner extra minutes of fire protection. “With the FireStop TB™ you are providing of which home operator and typically the fire section some add-on critical time required, by simply using a fire resistant material within the foam”. Says Mr Pedersen of Green Certification Roofing and Insulation. He further discussed “Another benefit is typically the flame spread and smoke index. With a smoke index of zero and also a flame propagate of 5, in the event of a fire particularly inside large homes, this would certainly supply the occupants the ability to see where they will likely escape the building”.

FireStop TB™ not simply provides a fireproof layer over the foam, but proper thermal protection as well. This benefit alone gives a important financial savings over pure intumescent coating, because with an R-Value above 4 per inch you may reduce one inch of closed cell foam and two inches open cell.

Other Benefits:

  • Increase or maintain your existing R-Value
  • Spraying over foam plus the trusses gets rid of thermal bridging at typical at the roof
  • Fireproofed the complete underside of the roof
  • Satisfy building codes and provide the code established with a fairly easy inspection
  • Introduce the most effective noise absorption products currently available into the attic.

FireStop TB™ has passed the NFPA 275 Standard Method of Fireplace Test for the Analysis of Thermal Barriers Applied Over Foam Plastic Padding Part 1 and Part 2. The test was conducted with both available and closed cell foams. This test provides popularity as a thermal buffer over all foam plastic-type insulation products.
