2. Firestop - Wikipedia

   en.wikipedia.org/wiki/Firestop

   A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fire-resistance rating of a wall or floor assembly intended to impede the spread of fire and smoke.

3. Packing (firestopping) - Wikipedia

   en.wikipedia.org/wiki/Packing_(firestopping)

   Packing with inherently fire-resistive materials, such as rockwool or ceramic fibre is intended to protect sealants that would, on their own, be consumed by the fire. Lesser packing, such as foam backer rod or fibreglass are used simply to hold up materials that can survive fire testing on their own. In both cases, the packing is placed in such ...

4. Fire blocking - Wikipedia

   en.wikipedia.org/wiki/Fire_blocking

   Fire blocking or firestopping terminology was used interchangeably in code language from its first mention in the 1905 National Building Code (NBC), and requirements were expanded in the 1927 Uniform Building Code (UBC). Building code terminology settled on different definitions of the terms by 2000. [4]

5. Passive fire protection - Wikipedia

   en.wikipedia.org/wiki/Passive_fire_protection

   Fire-resistance rated wall assembly with fire door, cable tray penetration and intumescent cable coating. Passive fire protection (PFP) is components or systems of a building or structure that slows or impedes the spread of the effects of fire or smoke without system activation, and usually without movement.

6. Fireproofing - Wikipedia

   en.wikipedia.org/wiki/Fireproofing

   Spray gypsum-based plaster fireproofing being installed. Circuit integrity fireproofing of cable trays, using calcium silicate boards. Damaged spray fireproofing. Fireproofing is rendering something (structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. [1]

7. Sealant - Wikipedia

   en.wikipedia.org/wiki/Sealant

   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 acrylic latex or polyurethane based) [2] and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or ...

8. Firestop pillow - Wikipedia

   en.wikipedia.org/wiki/Firestop_pillow

   Firestop pillow: Loose Fill/Fibreglass Bag type of firestop pillow. Usually this type of pillow contains a mixture of graphite and vermiculite. There are three types of firestop pillows: [citation needed] rockwool batts with intumescent resin inside plastic bags; vermiculite with intumescent graphite inside of fibreglass bags; intumescent foam ...

9. Intumescent - Wikipedia

   en.wikipedia.org/wiki/Intumescent

   These intumescent materials produce a light char which is a poor conductor of heat, thus retarding heat transfer.Typically the light char consists of microporous carbonaceous foam formed by a chemical reaction of three main components: ammonium polyphosphate, pentaerythritol, and melamine. [2]
