WYKAMOL CM20 MEMBRANE (40sqm roll)



Wykamol CM20 is the highest drainage capacity membrane in the CM range giving a void volume of 14 litres/m2. Suitable for use on floors and walls in very wet situations or where the large stud height is desired to maximize insulation values. When used on floors cm20 can normally be installed without the need for perimeter drainage channels and, when overlaid with concrete, the large diameter studs will give high point load resistance capabilities (150 kn/m2) to support load bearing walls built off the slab.
