Yesterday I cut all the various pieces of firewall insulation and ?seemed? them with aluminum tape. It is the kind of insulation, approx 3/16 thick, with an aluminum foil on each side. I tried to get some high-temp glue, but the stuff I was after, is not readily available here in Belgium. So I got some clear ? Poly Max?, a polymer sealer/glue from ?Bison?, from our local DIY.
It said on the cartridge that it would keep its normal strength up to a continuous 100?C (212 ?F). I am not sure how hot the Firewall gets, but I put a sample of the insulation, glued to a piece of stainless steel in the oven, with the following results:
10 min. @ 100 ?C: (212 ?F) No problem!
10 min. @ 125 ?C: (257 ?F) No problem!
10 min. @ 150 ?C: (302 ?F) No problem!
10 min. @ 200 ?C: (392 ?F) No problem!
20 min. @ 200 ?C: (392 ?F) No problem!
10 min. @ 250 ?C: (482 ?F) No problem!
? No problem? means I could not rip the insulation of the stainless steel without damaging it. Also the aluminium tape kept sticking real good! Unfortunately our oven does not get higher than 250?, but I am pretty sure that the Firewall will not get that hot in normal working conditions.
It is good to know that the Insulation will also help to keep the heat out in case of a FWF-fire (and that the insulation will stay on even when it gets quite hot)
