100% bio-based insulation, without any compromise
Breathe. Your home too. Mascork Pure Thermal Expanded Cork is the result of a unique natural process: agglomeration using only the tree's resin (suberin) under the action of water vapor. Harvested in the Atlas Mountains, this raw and noble material offers an exceptional thermal barrier while guaranteeing impeccable indoor air quality.
Why choose Mascork Pure Thermal?
Zero Additives, Zero Glue: A product composed exclusively of expanded natural cork, without any chemical or synthetic binders.
Ultra-Light and High Performance: With an optimized density between 95 and 130 kg/m³, it traps a maximum of air for superior thermal insulation (λ = 0.04 W/m°C).
Hygrometric Regulation: Its alveolar structure allows water vapor to pass through (breathability), preventing condensation and mold in old or new buildings.
Unalterable: Unlike mineral wool, Mascork does not compress over time and is naturally resistant to rodents and insects.
Ideal Applications
Exterior Insulation (EWI): The ultimate solution for eliminating thermal bridges while allowing your walls to breathe.
Roofs & Lofts: Ideal for protecting your home from summer heat thanks to excellent thermal inertia.
Heritage restoration: The preferred choice of architects for the renovation of historic stone or earthen buildings.
