Proctor Roofshield and Wrapshield breathable membranes from Dynamic Composite Technologies 
The Problem
Failure to consider condensation within your roof space and walls can have serious consequences. - Unseen mould growth.
- Saturation of insulation.
- Sick buildings.
- Corrosion.
- Timber decay.
- Loss of structural integrity.
- Ghost leaks.
- Expensive rectification.
What We Know
"Higher levels of insulation may introduce unforeseen problems where they are incorporated into construction styles which have previously been relatively immune to condensation. This is because insulation, whilst it keeps some surfaces warm, also keeps other surfaces cold." "A simple example is domestic roof spaces. High levels of ceiling insulation mean that roof spaces are colder as they are not heated to the same extent from below." (CSIRO, 2001) Proctor Group Australia offers a project specific Condensation Risk Analysis service to designers. Our Solution
Unlike foil and perforated foil products, the high water vapour permeability of the Proctor Roofshield and Wrapshield breathable membranes allows for the escape of vapour from within the building at the same time as restricting the ingress of moisture. - Protection against wind-driven rain, snow and dust during construction and for the life of the building.
- Highly durable, strong and lightweight textile membranes.
- Quiet when exposed to wind.
- Non corrosive for coastal environments.
- Vapour resistance no greater than 0.26MNs/g.
- Complete range of AS4200.1:1994 compliant products for walls and roofs.
- A systems approach including window surrounds and tapes.
Avoid Costly Mistakes
Before specifying a vapour permeable building wrap, be sure to check the vapour resistance data and make sure you are confident that it really does breathe. With a 20 year track record around the globe select a Proctor breathable membrane for your next project and let your building breathe.
