Polyester Flat Roofing...
Nordgum Polyester Flat Roofing System
Waterproofing membrane made of Polymer elastomer modified bitumen (SBS) and reinforced with a non woven polyester carrier. The compound is a mixture of distilled bitumen and thermoplastic rubber which is Styrene Butadiene Styrene (SBS). The bottom surface is covered by a poliethilene burn off film.
Two finishes are available
NORDGUM (plain) available in 3mm, 4mm and 5 mm thickness or 4 Kg/m2 and with upper surface covered with sand or poliethilene burn off film on request.
NORDGUM MINERAL available in 4 Kg/m2 and 4,5 Kg/m2, with upper surface covered by natural slate granules in order to protect the membrane against U.V. radiations.
Uses
NORDGUM is one of the most convenient solutions for roofing renovation work and general waterproofing. Nordgum achieves good values of mechanical resistance thanks to the non woven polyester carrier and excellent low temperature flexibility that permit it to be used in difficult climatatic conditions.
Membranes are particularly well suited for the waterproofing of structures which may be subjected to limited movement or dimensional changes such as: -
- Flat, sloping and pitched roofs
- site cast reinforced concrete
- prefabricated concrete
- masonry cement
- metal and laminated wood deck terraces
- foundations
- antiseismic foundations
- car parks
- stress structures
- tunnels
- underground railways
The high degree of elasticity and flexibility allow the use in conjunction with elastomeric and polymer plastomer modified membranes which are reinforced with non woven polyester fabric, and the use as complementary layer in a two layer waterpoofing system.
