Material on Firewall

[canadianscot86]

Can anyone tell me what material this is that is very commonplace in my area for putting on top of firewalls? I assume some sort of roofing felt, but obviously can't be sure.

If anyone can give me pro's and con's of this compared to say acrypol, I'd be grateful!

Thanks!

Yes felt, felt, if applied properly can give a long life. Acropol is used to stop leaks in roof coatings that have failed and ought to be replaced. Not the same thing at all.

Thanks - I live down on the south coast - seems like Acropol is the standard for covering firewalls - assume it's a no no then?

Its good stuff and can last for years and is commonly used but think of it as a repair not a fix.

Looks like torch on felt to me

And if that's bitumen roof felt or similar flammable material, that's no longer a fire break wall, and the home insurance policy will be affected.
