Roof renovation of an annex with Quattro
The client wanted to insulate his roof without changing the appearance and without working from the inside as the attic had already been occupied.
Facing this challenge, the roofer recommended insulating from the exterior with our Aluthermo Quattro: Aluthermo Quattro is an insulation material, breather membrane and vapour barrier all in one. This is an advantage when it comes to the installation and especially if you want to avoid an increase of the roof to keep the appearance. Furthermore it avoids changing the downpipes and gutters.
The client first removed the mineral wool which wasn’t in good condition anymore and rolled Aluthermo Quattro out above the rafters. Afterwards, the overlaps and joints were sealed up with the Aluthermo adhesive tape, before putting the battens and counter battens.
