ALKORPLAN A Fully Adhered System with Mineral Wool Insulation

A light grey, calendered, flexible PVC membrane with a fleece backing for use as a waterproof membrane within partially or fully bonded single-ply roofing applications. It is particularly suitable for covering existing bituminous roof finishes.

AlkorPlan® A is designed to be UV, and weather resistant with high moisture vapour permeability, and high resistance to bacteria and root penetration.


Sheets of AlkorPlan® A can be joined by either hot air welding, by solvent welding, or by sealing with Alkorplus aluminum tape with a strip of AlkorPlan® 35170 membrane welded over the joint.
