Kerabit Dual is a membrane which is overlapped halfway across the width, the result being a secure dual-layer roofing conveniently with one product, involving no hot work. Kerabit Dual is grey in colour. One roll will provide 4m2 of finished roofing.
Kerabit Dual, which has been designed for a do-it-yourself builder for waterproofing of balconies, has been developed further to suit roofs with an inclination of 1:2 – 1:20. Dual is particularly well suited for low-inclination roofs.
Adhesive very sticky
In order for the roofing to be secure and remain waterproof for years, the adhesive surfaces must effectively adhere to one another. Take the high adhesiveness into account when installing Dual. Once the adhesive surfaces have been laid against one another and have adhered to one another, the installation can no longer be amended without new lengths.
The outside temperature should be at least +10oC when Kerabit Dual is installed. Note. Dual is only for cold balcony structures.
