Hi Paul

You query might be better served by asking the manufacturer.
One question I would ask them; if their product is fire resistant.

Cheers,

I cannot find it under Ministry Approvals - BMEC

I have sent an email but I really don’t expect a reply. If I do, I’ll post it here.

I could not find any CSA approval or any mention regarding fire. As Claude has pointed out is does not appear to have Ministry approval.
