Square double roofing hexagon
SQUARE DOUBLE ROOFING 11 EXAGON
Suitable for roofs with a pich greater than 40%.
We have already shown the aesthetic importance in choosing the type of “roof” covering for every type of construction. By using slate slabs 57x30x1 cm. and trimming them at the base, a particularly pleasing hexagon shape is obtained when installed, as can be seen in the photo. This type of roofing is technically similar to the double roofing + 11 cm of overlap on the 3rd row and therefore is just as strong and has all the fundamental characteristics of impermeability, insulation and resistance to the elements typical of slate roofing.
CARATTERISTICHE
- Slate slabs 57 x 40 cm, 9/10 mm thick, or
57 x 30 cm, 9/10 cm thick - Fixing: 11 cm hooks in stainless steel or
copper, 3 mm diam., better if 4 mm diam.
