Insulation of rafter gaps from the inside
If the attic is not yet inhabited and the roof plane is not covered with plasterboard (or paneling), we are on time! In this case, we will make the attic thermal and waterproofing from the inside.. With PU foam, you get more effective attic insulation than any other insulation! It can be used on any material. We insulate on foil, OSB board, plasterboard, but even directly on tiles.
Attic thermal insulation - why with foam?
- When working with traditional insulation materials, 15 cm rafters make it impossible to install strong insulation. The great advantage of closed-cell foam is that 15 cm of thickness is equivalent to more than 30 cm of cotton based on the lambda value!
- If your roof structure is in poor condition, a major advantage is that closed-cell foam also provides waterproofing. It is doubly protected against leaks caused by shifting tiles and powder snow.
- The cotton wool used for attic insulation will slide off, shift, and collapse from moisture and water ingress after a few years. The closed-cell material is completely free of gaps and gaps, and it completely takes on the shape of the roof plane to be insulated, it will never move. It is airtight, the wind does not blow through it like traditional insulation.
Roof insulation from the outside!
If the attic is already inhabited or the roof plane has already been closed with drywall, we still have a solution. In such cases from the outside, after moving the tiles we prepare the insulation. We arrive at the job with our own carpenters, after opening the rafters We immediately insulate the inner receiving surface and then replace the tiles. Öhe does not have to coordinate several professionals and worry about flooding caused by sudden thunderstorms.
The process of thermal insulation on the tile side
After removing the tiles, we decide in consultation with the customer about the fate of the old insulation. The old, slipped, collapsed cotton is usually removed from the roof and the exposed surface is cleaned. The polyurethane foam is then blown onto the receiving surface. If the customer wants to install a new receiving surface, we attach foil or OSB sheets between the rafters. After installing the desired insulation, the tiles are put back on the roof.
DISADVANTAGES OF CONVENTIONAL WOOL ATTIC INSULATIONS
Cotton does not provide waterproofing.
Cotton insulation is not leak-proof.
Wool moves.
15 cm rafters set narrow boundaries.
Installation of sheet materials is difficult.
Insects get through it, gnats make nests in it.
WHY IS EXPANSION FOAM INSULATION THE BETTER CHOICE FOR ROOF SPACE?
Expanded foam is the most effective thermal insulation available today, and it is also waterproof.
There are no gaps or drafty corners. Completely airtight.
Half that thickness of foam is enough.
The sprayed technology is fast: up to 300 m2 can be insulated per day.
Rodents don't like it, they don't move in.
