WATERSHIELD 90

Breathable Waterproofing Membrane
(Moisture Barrier & Vapor Regulating Membrane)

WATERSHIELD 90 is a breathable waterproofing membrane with a three-layer structure, formed by a polyethylene (PE) film layer positioned between two polypropylene (PP) layers, used in the construction sector as a moisture barrier and vapor regulating membrane.

Thanks to its advanced 3-layer technology, it provides a structure that allows vapor permeability while ensuring full waterproof protection. With this feature, it provides effective protection against condensation, moisture formation, and air leakage in exterior façade applications. At the same time, with its vapor regulating function, it helps moisture formed within the building envelope to be discharged in a controlled manner.

In building applications, the main factor determining product performance is not only the weight, but also the functional working principle of the layers. In this regard, WATERSHIELD 90 offers a long-lasting, durable, and high-performance moisture barrier and vapor regulating membrane solution.
