What is Lamitech n?

Lamitech N

Lamitech n is a multilayer polymer sheet, specially designed for outdoor floors decoupling. Protects tiles against substrate tensions, reducing the risk of breakage and piece lifting. Suitable for outdoor waterproofing. Coextruded HDPE/EVAC membrane, with one side covered with polyester fiber and the other one with polyester entwined felt, that allows laying with cement-based adhesives. Absorbs tensions, reducing their transmission to the ceramic floor. Suitable for indoor and outdoor use.
