Enviroseal ProctorWrap Roof Sarking for High Tensile Roofs - 50m x 1500mm = 75m² per roll
About Enviroseal™ ProctorWrap™ High Tensile Roof Sarking
Enviroseal ProctorWrap High Tensile Roof Sarking (HT-R) is a highly durable medium duty vapour permeable roof underlay for use in tiled, slate and metal roof applications.
Enviroseal ProctorWrap HT-R offers a combination of durability and high water holdout without compromising vapour permeability to help protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.
Enviroseal ProctorWrap HT-R shall be installed in accordance with AS/NZS 4200.2 Pliable Building Membranes and Underlays, Part 2 Installation Requirements, and with the printed face upwards. For tile and slate roof applications, Enviroseal ProctorWrap HT-R should be laid horizontally across the rafters starting at the eaves with adequate drape to allow drainage of moisture, and secured in place with battens and/or counter-battens.
For metal sheet roof applications, Enviroseal ProctorWrap HT-R should be laid so it forms a continuous membrane over the entire area of the roof, allowing any water to drain down to the gutters. On low pitch metal roofs, excessive draping of Enviroseal ProctorWrap HT-R between purlins can result in ponding which is unsatisfactory and should be avoided.
It is preferable for Enviroseal ProctorWrap HT-R to be fully supported to give a clear drainage path. If not practical on low pitch roofs then laps should be taped using ProctorWrap SLS tape to prevent water ingress to the insulation below.
