Dave,
I heard a long time ago that the paper on insulation burns extremely fast. Do you know anything about that? It was one of the reasons I thought this work was especially dangerous.
We don't have a paper coating on our fiberglass batts here.
We have fiberglass batts between all studs and between the ceiling runners.
The latest Building Act here requires 150mm of batts stuffed into a 90mm stud thickness.
In the ceiling, you can't put lights like your customers give you any where, they have to comply with the regulations here.
Mind you that is good, with all the dodgy stuff coming out of China, I don't want a house fire on my conscience.
DIY Lighting stores eh??.
