Proper insulation

ISOFOLIE® for roof and wall

Specially manufactured air cushions and highly reflective, aluminium-vapourised foils — for indoor and outdoor use, in roof and wall areas.

Construction of ISOFOLIE®: air cushions between two aluminium-vapourised, reflective foils.

Reflect radiation instead of storing heat

ISOFOLIE® is used to reduce and prevent solar radiation input or heat radiation losses, as well as transmission heat losses. It can be used in roof and wall areas to reduce cooling and heating loads.

Specially manufactured air cushions and highly reflective aluminium-vapourised foils lend ISOFOLIE® exceptional properties for indoor and outdoor applications. Particularly noteworthy are the thermal conductivity lambda of 0.0198 W/(mK) and the reflection of up to 99 % of solar, cooling and thermal radiation.

ISOFOLIE® makes slim building constructions possible at the same insulation performance. The calculation is carried out according to DIN EN ISO 6946 with the energy demand calculation software from Hottgenroth.
