As one of the original roofing membrane manufacturers, we have over 35 years of experience manufacturing roofing underlays for the European construction industry. Our range of underlays provides different functions to suit various roofing requirements.
Applications
Vapour Permeable Underlays
Water vapour is created by several regular household activities, including bathing, cooking, washing and drying clothing. Vapour mainly diffuses through windows and vents, but around 20% can leave through the ceiling and enter the roofing cavity, causing a condensation risk.
The use of RoofTX® low resistance (LR), vapour permeable, air barrier underlays allows this moisture to diffuse through the membrane to the outside. Our Roofshield® product offers vapour and air permeability with a meagre vapour resistance.
Vapour Barrier Underlays
Conventional ventilated pitched roof construction utilises an air and liquid barrier roofing underlay.
Specifically developed as a modern, cost-effective, lightweight alternative to traditional type 1F bitumen felts, MultiTX® Plus is a high vapour resistance (HR), air and liquid barrier underlay. It is durable, clean, easy to cut and install, and offers excellent temporary protection against the elements.
Vapour Control Layers
Specific construction designs call for a complete air and vapour barrier to control condensation and air movement within the building.
Our vapour control layers are high-resistance vapour barriers for internal walls, ceilings and floors, specifically designed to prevent water vapour from transferring through the structure when placed on the warm side of the insulation.
Integral Tape
A single integral tape underlay for roof membranes allows for ease of installation and effectively seals horizontal laps to help increase thermal efficiency.
Our integral tape product, RoofTX® CONSEAL, has been designed to reduce air infiltration and convective heat loss whilst improving wind uplift performance. RoofTX® CONSEAL is less bulky than more traditional, dual-taped products, which results in reduced waste as roll widths can be reduced to suit site requirements.
