ProctorWrap HTR

ProctorWrap HTR is a heavy weight, UV stabilised, tear resistant 3-ply spun-bonded polyolefin membrane with reinforcement scrim. ProctorWrap HTR meets the requirements of AS/NZS 4200.1:2017 and is suitable for use in roof and wall applications. 

Vapour control: Class 4 Vapour Permeable

Applications:

ProctorWrap HTR is medium duty classification and suitable for use underneath metal sheet, slate and tiled roofs. Being heavier weight, ProctorWrap HTR is commonly used for pitched roofs, heritage projects, and under natural slate and tiled roofs where during construction the membrane is exposed to higher levels of foot traffic and wind loads. ProctorWrap HTR can significantly reduce the risk of condensation in the roof space, when designed and installed correctly. HTR is suitable for use in BAL regions 12.5 to 40 in accordance with AS 3959.

Features:

• High water resistance
• 1.5m x 50m - 67.5m2 coverage per roll (approx.)
• Heavy weight
• High nail tear strength
• Class 4 High vapour permeance
• Medium duty suitability for tiled and metal roof applications
• Exceeds NCC deemed to satisfy condensation management provisions
• Used in Australia since 2009

Durability:

Although ProctorWrap HTR can be used as temporary protection during construction, it is not a waterproof membrane as classified by AS 4654.2. The product may be damaged by careless handling, high winds or vandalism. Any damaged areas should be replaced before completion. To ensure maximum long term durability, ensure that ProctorWrap HTR is covered up by the primary roofing or cladding material as soon as possible, and not left exposed to UV for longer than 2 months.

When used together with the ProctorWrap High Tack Tape 60mm (Black) during installation to tape joins and penetration - and ProctorWrap Plasti Grip Washers to fasten to wooden and steel frames - it will help provide an air-tight barrier.

Physical Weight: 19kg per roll
