Kerabit 3300 UTL Nature

The low-carbon status of Kerabit Nature^® products is achieved, for example, by replacing some of the traditional raw materials with bio-based raw materials and recycled materials.The carbon emissions (GWPtotal) during the manufacture of Kerabit Nature products are approximately 59 % lower than for corresponding basic products. Apart from environmental impact, the characteristics of the products correspond to the analogous basic products. We are especially careful about the waterproofing properties – we don’t compromise on them!

Kerabit 3300 UTL Nature is a line-torch-on underlay membrane in multi-layer membrane system.

The carrier consists of polyester. The underside of the product is coated with torch-applied bitumen, the top surface with sand.
