TwinSkin Systems

Beat condensation issues with Topglass TwinSkin

Twin-skin fibreglass systems is the perfect solution for buildings where condensation could be an issue. Twin-skin Systems also reduce noise levels from outside influences.

Technical specifications

Two independently-formed sheets of Topglass® are laid over each other to form an effective air gap between the sheets. Condensation evaporates, and this prevents water droplets entering the building.
