Six things
Heat in winter
The membrane reflects heat back into the house and prevents it from being lost through the roof.
Coolness in summer
It reflects 95–97% of thermal radiation. The habitable attic remains habitable in August.
Moisture away
It controls vapour and keeps moisture away from the insulation. No mould.
Quiet inside
The layers attenuate the noise of rain and of the street.
Shape for years
Wolle insulation does not settle. The thickness and performance remain the same.
Air in place
The layers taped at the joints stop air currents.
What do you wish to insulate?
Choose the part of the house you are insulating and see the appropriate build-up, layer by layer, from the roof to the walls.
Building passive or nZEB? Everything is here
The complete system for nearly zero-energy houses, with certified performance across the entire build-up.
Warranty of up to 50 years
Commercial durability warranty, with a certificate and registration number.
Less thickness
R 6.21 m²·K/W with 10 cm of Wolle (System 10 Premium+), equivalent to 24 cm of conventional insulation with λ 0.038.
R (m²K/W), thermal resistance: the extent to which the layer or assembly resists the passage of heat; the higher it is, the better it insulates. What it means →Calculated performance
Thermal resistance of 10.38 m²·K/W with 25 cm of Wolle (System 10 Premium+), a value calculated for the entire build-up.
The insulation you live with
Wolle is certified OEKO-TEX Standard 100, Class I: free of formaldehyde, free of chemical binders.
Does not settle
Wolle does not tear and does not crumble. It is inert to moisture and to repeated cycles of wetting and drying.

that
holds
Here will be your house
New house, existing house or flat: you answer a few questions, send us the photographs and videos, and we prepare the proposals, with every detail considered from the outset.
Request the design →
1You answer and send the photographs
Questions about the plot, family, rooms, cars and budget. You may send the photographs, 360° videos and voice messages via the website, by e-mail or on WhatsApp, in any language.
2You receive 2–3 proposals
Plan, massing and an image of the house in the landscape, with an indicative budget and the bill of materials.
3You choose, and the full design is produced
The full design, including building services and the bill of materials, is produced after you choose the proposal and is checked and signed by partner architects.
