The same habitable attic, in summer and in winter: cool in August, warm in January
Isoflect Insulation · complete thermal insulation systems for interiors

Insulation that holds

What does it keep?

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.

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 →
R 10.38

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.

Clean air

The insulation you live with

Wolle is certified OEKO-TEX Standard 100, Class I: free of formaldehyde, free of chemical binders.

Stable

Does not settle

Wolle does not tear and does not crumble. It is inert to moisture and to repeated cycles of wetting and drying.
