ProctorWrap High Tensile (HT) insulation
by Dynamic Composite Technologies 
Increased insulation at ceiling level and improvements in the air tightness of buildings impacts on the amount of vapour laden air entering a cold roof space resulting in damaging condensation. Breather membranes are an important part of the modern roof construction. Proper installation prevents water migration into the building from wind driven rain and also facilitates the safe passage of vapour beyond the vapour permeable membrane without condensing. ProctorWrap High Tensile (HT) is a UV stabilised, rot proof and tear resistant 3-ply spun bonded polypropylene fabric with reinforcement scrim. It has been designed to protect the insulation and the building fabric from moisture ingress during construction and for the life of the building. Unlike foil products, High Tensile (HT) due to high vapour permeability lets the building breathe. In temperate climates the membrane permits vapour to escape without reaching dew point thus preventing condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance. High Tensile (HT) has been designed to meet the stringent AS/NZS 4200.1 requirement for classification as a medium duty membrane for use under tiled roofs. The highly durable, strong and lightweight textile membrane is silent when exposed to wind, will last the lifetime of the building, even in corrosive coastal environments, and will not interrupt television and radio signals. Features; - high vapour permeability.
- tested to AS/NZS 4200.1.
- suitable for use under tiled roofs.
- UV stabilised for 2 months exposure during construction.
- strong, yet flexible and lightweight for ease of use.
- mould resistant.
- superior nail tear resistance and nail seal.
