As one of the original roofing membrane manufacturers, we have over 30 years’ experience in the manufacture of roofing underlays for the European construction industry. Our range of underlays provide different functions to suit a variety of roofing requirements.
Applications
Vapour Permeable Underlays
Water vapour is created by a number of regular household activities, including bathing, cooking, washing and drying of clothing. Vapour mainly diffuses out through windows and vents, but around 20% of this vapour 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 both vapour and air permeability with a very low 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 a durable, clean, easy to cut and install, and offers excellent temporary protection against the elements
Vapour Control Layers
Certain 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 the transfer of water vapour through the structure when placed on the warm side of the insulation
Integral Tape
For roof membranes a single integral tape underlay allows for ease of installation and effectively seals horizontal laps, to help contribute to increased thermal efficiency.
Our integral tape product, RoofTX® CONSEAL, has been designed to reduce air infiltration and convective heat loss, whilst improving wind uplift performance. In fact, 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.
