ALU Vent 100: Vapour-Permeable Foil

ALU Vent 100 is a high-quality vapour-permeable insulation foil, developed for application on the cold side of pitched roofs and walls. Compared to ALU Vent 45, this foil has a thicker structure, providing higher thermal performance and actively contributing to a better insulated building.

The foil reflects radiant heat and regulates moisture transport, helping to prevent condensation problems. In this way, ALU Vent 100 contributes to a healthy indoor climate all year round.

How does ALU Vent 100 work?

ALU Vent 100 consists of multiple layers, including a 100% aluminium inner layer that efficiently reflects radiant heat. On the outside, the foil is equipped with a vapour-permeable spunbond membrane that is waterproof, while still allowing moisture from the inside to escape. This makes the foil particularly suitable for vapour-open constructions, where moisture regulation is essential to keep the building envelope dry and healthy.

Whereas traditional insulation materials primarily work by absorbing and storing heat, this foil functions through reflection. Thanks to the aluminium top layer, heat is reflected back inside during winter, or kept outside in summer. With only a few millimetres of thickness, ALU Vent 100 delivers excellent performance in terms of thermal insulation and workability.
