Attic insulation

Polyurethane is undoubtedly the best choice in the attic, between the rafters. We insulate from the inside or outside.

Material:

Closed/open cell

Progress:

300 m2/day

Density:

15 or 35 kg/m3

Roof insulation from the inside

If the attic is not inhabited and the roof plane is not covered by plasterboard or paneling, we can insulate it from the inside. The attic insulation will be really effective with the foam! Purfoam can be used on any construction material used today. Spray on foil, OSB board, plasterboard, or even directly on tiles. The material is vapor-diffusive, so your house stays breathable!

Why is it unbeatable?

Working with traditional insulating material, the 15 cm rafters make it impossible to install strong thermal insulation. This layer thickness of closed-cell foam corresponds to 30 cm of cotton.
The insulation provides waterproofing even in the smallest thickness. If your roof structure is in poor condition, this is a huge advantage. Even when standing under a new shell, it is reassuring that we are doubly protected against getting wet, shifting tiles, and powder snow.
The cotton used for attic insulation slips off and collapses after a few years. The closed-cell material we offer is rigid, strong, statically strengthens the roof structure and will never move.
The foam is joint- and seam-free and completely takes the shape of the roof plane to be insulated. It is airtight, the wind does not blow through it like traditional insulation.

Insulation of the roof plane from the outside

If the attic is already inhabited or the roof plane has already been sealed with plasterboard, instead of making a big fuss, we prepare the insulation of your home from the outside. This method is more expensive than in the case of insulation sprinkled between the rafters. We come to the job with our own carpenters, and we carry out the demolition and reconstruction of the shell below the market price. If the roof is demolished by another contractor, precise coordination is important, a thunderstorm can surprise the owner. With our own team, we do not demolish the entire roof, as soon as we uncover a strip, we immediately insulate and seal it.

Work progress

After removing the tile, we decide the fate of the old insulation in consultation with the customer. The old, slipped and collapsed cotton is usually removed from the roof and the hollow space that has been discovered is cleaned. Then we spread the foam on the receiving surface, which is usually the plasterboard or paneling bordering the living space. If the customer wants to install a new reception area, we attach foil or OSB sheets between the rafters. After installing the desired insulation, the tiles are returned to the roof.

FAULTS OF COTTON INSULATION

Cotton does not provide waterproofing. As a result of incoming moisture and steam, it rots and collapses.

Insulation is not seamless, thermal bridges are created. Gaps remain at the joints, air passes through the insulation.

Over the years, cotton slides down under the influence of gravity and is easily displaced.

The rafters limit the insulation (15 cm). If there is still a way to place thicker insulation (for example, thanks to an expensive elevation), then it will come at the expense of the height of the attic.

Insects get through it, gnats make nests in it.

Difficult installation, big upheaval.

FOAM INSULATION

Even half the thickness is enough to achieve the same thermal insulation. The rafters set no limits! The 15 cm rafter gaps accommodate up to 30 cm of foam equivalent to traditional insulating material!

Purfoam not only provides excellent thermal insulation, but also 100% waterproofing. You will be doubly protected against getting wet! No more fretting over shifting tiles or powdery snow.

Perfect, form-following, gap-free insulation. Air does not pass through. Completely airtight layer!

Fast installation, insulation of up to 300 m2 per day is possible in accessible attics. Since the material and machines are on the truck - there is no upheaval.

Rodents don't like it, they won't move in!
