A comment
Inherited a house with an attic, just terribly cold.When the workers climbed to find out why, they realized that the roof was not protected at all, was already decaying. The team leader advised putting Paroc Extra insulation, which becomes shrink-free. I thought I couldn’t find it in the district center, I calmly bought it in the market. He looked outwardly loose, but the roofer knew better. I was pleased with the convenience of delivery.
The master was not mistaken: he carefully watched, I know. When pulled out, sheets grow 3-4 times, spring, mount without sagging, no unnecessary seals, dust. The guys, leaving the tool, threw them without fixing, not a single sheet fell off. The workers grumbled a bit that there was no clamping edge, but they could easily do without it. Failure and damage during installation were not found. In winter, I drive my daughter out of the attic with a stick!
pros
everywhere, profiles are pressed, so there is a lot of material in the package (easier to transport); the form is quickly restored; monolithic sheets, uniform, lightweight, stable, excellent heat holding
