Alkor
Alkor is a thermoplastic membrane based on monomeric PVC-P. alkor, although traditionally
installed on flat roofs, Alkor is now commonplace on pitched and barrel vaulted roofs
due to its flexibility and aesthetic qualities.
The alkor membranes have five main advantages :
- Cost-effectiveness:
- economies on the installation costs: one single 30m² roll replaces 6 bituminous
rolls in a 2 layer system.
- economies on the structure costs: the waterproofing is 5 times lighter than the
traditional multilayer systems.
- economies on the maintenance costs: generally limited to bi-annual inspections.
- Fire Safety:
- up to FAB* (BBA approval 96/3307/c)
- external fire up BROOF(T4)* (ENV1187/4)
- Aesthetic: adaptable to most roof substrates, broad colour range and integrity of
the seams.
- Reliability: vapour permeability, flexibility, static and dynamic perforation resistance.
- Durability: life expectancy assessed by the BBA (British Board of Agreement) as
in excess of 30 years.
