Kerabit Titan 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 Titan Nature has been developed especially for modern low mono-pitched roofs. On low mono-pitched roofs, the absolute tightness, flexibility and carefully executed details become even more important properties. Thanks to the unique weathertight seam, Titan is suitable for inclinations up to 1:20. The colour of Kerabit Titan Nature is black. 

Kerabit Titan Nature is a functional roofing solution with details that guarantee tightness. The roofing has 150 mm wide seams with special nailing edge to ease fastening to the substrate. The adhesive seams attach to one another in a uniform and tight manner. There are no nails or screws visible on the finished roofing!
