BauderJFRI WFRL Membrane (Water Flow Reducing Layer)

BauderJFRI WFRL Membrane (Water Flow Reducing Layer) is a flexible sheet of polypropylene strands randomly spun-bonded together, in a CFC free process. UV stabilized to reduce degradation by sunlight. Embossed and textured surface to minimize reflected glare. It is supplied as part of the JFRI Inverted Insulation System to minimize water flow through and below the insulation. 

This product known as a Water Flow Reducing Layer (WFRL) is for use as a separator sheet over BauderJFRI and BauderGLAS Inverted insulation, in order to reduce the cooling effect of rainwater, and therefore improving the thermal performance of the insulation, whilst also helping to reduce the flotation effect reducing the weight of ballast required. BauderJFRI WFRL Membrane is breathable, therefore will not create a condensation trap within the construction.
