Pro Clima Solitex Fronta WA is used to weatherproof external timber frame walls. Its 3-month UV exposure resistance protects the timber frame building from the weather during the construction phase (before external protective cladding is added) as well as long term once the external closed timber cladding is completed. It is fully windtight and its high vapour diffusion openness (breathability) gives Fronta WA a very low resistance to moisture that greatly helps in the drying of the wall and releases any moisture in the timber or insulation that needs to escape.
Pro Clima Solitex Fronta WA vapour permeable membrane can be used on walls of timber frame buildings where the wall will have closed screen (no gaps) timber cladding on top of the membrane.
Solitex Fronta WA is a lightweight and robust 3-ply membrane consisting of a protective underlayer, TEEE windtight breather membrane with a polypropylene microfibre fleece cover. It is lightweight yet highly robust offering optimum protection for the structure against driving rain, snow and wind. It also protects the structure from dust during construction.
Before the cladding is installed, the membrane can be exposed to the elements for 3 months which provides easier scheduling of on-site works.
The membrane in Solitex Fronta WA is monolithic which means moisture vapour actively diffuses through it. This makes it fully windtight and breathable at all times; even when there is no air movement around the membrane. Microporous membranes need air movement to pass vapour through millions of microscopic holes, this means they can never be truly windtight. Unlike Microporous membranes, Monolithic membranes resist contamination from oils on site or turpentine in wood which may affect watertightness.
The active moisture transfer capability of the membrane offers a high degree of safety against condensation issues in the UK and Irish climate. Excellent drying capacity is essential to safely deal with any unforeseen moisture ingress, leaks or high humidity/wetness during the construction phase.
The printed face of Solitex Fronta WA has handy installation guidelines printed on it to make is easier for installers to correctly measure lengths, space out staples and align overlaps to the optimum depth for taping.
