Water flow reducing layer membrane 

Flexible non-woven polyethylene membrane. UV stabilized to reduce degradation by sunlight. Resistant to passage of liquid water. Membrane is breathable, therefore will not create a condensation trap within the construction. Minimizes insulation thicknesses required to achieve specified u-values by reducing the cooling effect of rainwater build up between waterproofing and insulation.

It is supplied as part of the BauderXPS (300) Inverted Insulation System, situated on top of the inverted insulation and under the specified surfacing. For a comprehensive specification contact Bauder technical department.
