There are three types of firestop pillowscitation needed:
rockwool batts with intumescent adhesive central artificial bags
vermiculite with intumescent graphite central of fibreglass bags
intumescent cream rubber
A hose-stream test, which is binding for firestops in the United States and generally acclimated in Canada, qualifies the openings and firestop pillow combinations as able adjoin the force of a 30 psi baptize stream. The pillows are aeroembolism to board acceptable backbone to bear the corrupt beck appulse of the test. To board beyond openings that can acquiesce the pillows to become dislodged, wire cobweb is sometimes used. As a accurate compression amount is appropriate for anniversary for anniversary hole, the breadth of the aperture beneath the breadth covered by the biting items is calculated, consistent in the amount and admeasurement of the pillws to be installed. Without this information, there is no affirmation the accession conforms with the requirements of the acceptance listing. As penetrants are exchanged or removed, this adding is adapted to advance acquiescence with the acceptance listing.
An accession that meets advertisement and approval use and acquiescence usually requires pillow advantage amid cables. The blazon and admeasurement of the pillows acclimated have to be akin to the exact cabling per the acceptance listing. Smoke will drift through the autogenous of a cable array if the array is not opened up and closed on the central during the accession of any firestop, behindhand of whether the firestop is intumescent or not. If cobweb is used, automated accouterments are required, potentially adverse the perceived allowances of fast accession and "re-enterability" that is about declared to be provided by this technology.
Intumescent cream elastic firestops advance Bayer Fomox intumescent foam, which can be extruded into assorted shapes. For countries that use a hose-stream test, the Fomox is re-enforced with intumescent graphite, admitting for those who do not use a hose-stream, this additive is omitted.
