VapR-free Plus
is a multi layer laminate film composite made of polyolefin materials,
resulting in a pitched roof underlay that has high vapour permeability
but is also highlywater resistant.
VapR-free Plus can be
installed without the need for roof space ventilation, and is suitable
for both Commercial and Domestic buildings, it is the ideal roof underlay
for Warm and Cold Pitched Roofs. Manufactured without the use of CFC’s
VapR-free Plus is 100%
recyclable and is very durable with high tensile and nail tear strength
properties. These, coupled with excellent UV and heat stability properties
ensure a life-span in excess of 30 years.
