2. Firestop - Wikipedia

   en.wikipedia.org/wiki/Firestop

   They receive a fire rating by combining materials in an arrangement specific to the item (a pipe or cable, for example) penetrating the fire-rated wall or floor and the construction arrangement of the fire-rated wall or floor. A two-hour-rated pipe-penetration firestop may consist of a layer of caulking over packed mineral wool. The arrangement ...

3. Sealant - Wikipedia

   en.wikipedia.org/wiki/Sealant

   Self-leveling silicone firestop system used around pipe through-penetration in a two-hour fire-resistance rated concrete floor assembly. Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if ...

4. Duct (flow) - Wikipedia

   en.wikipedia.org/wiki/Duct_(flow)

   The adhesive on so called duct tape dries and releases with time. A more common type of duct sealant is a water-based paste that is brushed or sometimes sprayed on the seams when the duct is built. Building codes and UL standards call for special fire-resistant tapes, often with foil backings and long lasting adhesives.

5. Intumescent - Wikipedia

   en.wikipedia.org/wiki/Intumescent

   Once the water is spent, the insulation characteristics of the char that remains can retard heat transfer through the fire stop assembly. Soft char products are typically used in thin film intumescent materials for fireproofing protection of structural steel as well as in firestop pillows .

6. List of fire-retardant materials - Wikipedia

   en.wikipedia.org/wiki/List_of_fire-retardant...

   Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.

7. Fire-resistance rating - Wikipedia

   en.wikipedia.org/wiki/Fire-resistance_rating

   A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.
