CONSTRUCTION MEMBRANES

A Proctor Group's ongoing research and development has resulted in a complete range of construction membranes for use in a wide variety of wall and roof systems to prevent interstitial condensation. Although Proctor membranes are supplied all around the globe, the membranes are developed to meet the specific demands of local climatic conditions, standards and construction methods. This is most recently witnessed with the launch in 2010 of ProctorWrap Black Label (BL) and in 2009 of ProctorWrap Air Tight (AT) and ProctorWrap High Tensile (HT), designed to meet the stringent requirements of the Australia and New Zealand sarking standards. 

These new products complement our established range which include Proctor Roofshield and ProctorWrap High Perm (HP), long recognised as the most breathable on the market. 

A Proctor Group's breathable membranes used on the cold side of the insulation are developed primarily for use in timber or steel frame construction and afford effective protection during construction against rain, snow and dust. These highly durable, strong and lightweight textile membranes are quite when exposed to wind and will continue to protect the building envelope for the lifetime of the building. 

Unlike foil products, the high water vapour permeability of A Proctor Group's membranes allow for the controlled escape of vapour from within the building whilst restricting the ingress of moisture, thus helping to protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance. 

Vapour Control layers are used on the warm side of the insulation to reduce vapour penetration into the structure and are recommended for use in areas of higher temperature and humidity and/or higher levels of insulation, such as aquatic centres, high occupancy buildings, certain agricultural and industrial buildings, kitchens and bathrooms.

Benefits of the Proctor Group range include:

• Proctor Roofshield and ProctorWrap High Perm: unique air permeable breather membranes offering the highest vapour permeability of any construction membrane available globally
• Full range of ProctorWrap products to meet Australian standards for use in all roof and wall constructions
• Vapour permeable sarking membranes are all manufactured in Europe and compliant with the AS/NZS 4200.1, European and ISO 9001 standards
• Vapour control layers are suitable for all types of construction including high risk applications such as swimming pools.
