Wovar Vapour permeable foil for closed roof and facade

Are you looking for vapour-permeable foil for closed roofs and facades? This vapour-permeable building foil for closed roofs and facades is supplied per full roll of 1.5 x 25 meters and 1.5 x 50 meters. You choose from two different variants. Namely with self-adhesive strip and without self-adhesive strip. Do not forget to order the appropriate adhesive for construction film. If you work with nails or staples, you should also order our tape for foil. This ensures that the foil does not leak at the hole of the nail or staple.

When to choose Vapour permeable foil for closed roof and facade

The beige vapour-permeable building foil can only be used for closed facades and roofs from 25 degrees and higher. With flat roofs, there is no guarantee that every roof tile is watertight. That is why we apply this rule. Vapour permeability means that the moisture or condensation that arises due to temperature differences in the cavity can escape, but the water from the outside does not get a chance to enter. As a result, this vapour-permeable building foil is also called water-retaining building foil for closed facades.

Applying the vapour-permeable building foil for a closed roof and facade is quite simple. Because we understand that this is not an obvious task when you do this for the first time, we explain below how you can best apply this vapour-permeable construction foil. We recommend that you always opt for the high-quality tape and glue from Wovar itself.

Apply vapour permeable construction foil for closed roof and wall

Apply the foil from left to right. Always start at the bottom. Secure the foil with stainless steel staples 10 or 20 mm. Don't shoot every 25 cm. This prevents wind from getting under the foil. The past tells us that if you only use glue, the foil can come loose after 5 years. This causes the foil to flap and you will suffer from annoying noises. For the overlap, use foil glue from a tube. Always work seams and staples with our special foil tape! Before nailing or screwing slats, it is important to apply batten tape between the slats and the foil. The batten strap is provided with special foam that seals the holes of the screw or nail. This prevents the foil from leaking onto the relevant mounting holes. Always allow for a 10 - 15 cm overlap. Use a handy snap-off knife to cut the film to size.

Because the glue comes in handy tubes, applying the glue with a caulking gun is super convenient. In addition to the normal building foil for closed roofs and facades, Wovar also supplies self-adhesive foil for closed roofs and facades. This does not mean that the foil is completely self-adhesive. A self-adhesive strip is only applied to the edges of the foil. You do not need to use glue with this film. Remember to cover up the staples and seams with foil tape.

What do I need to assemble vapour permeable foil for closed roof and facade?

What you need partly depends on the film you order. With self-adhesive foil it is not necessary to order foil glue. If you opt for vapour-permeable construction foil without self-adhesive tape, we recommend that you do so. In addition, you attach the construction foil using stainless steel staples. Which staples these are exactly depends on the device you are using. Always use stainless steel staples. Most commonly used are those of 10 or 20 mm. Finish the staples with our foil tape. Also work away the seams that arise at the overlap of the foil. When applying slats to the foil, it is important that you seal the screw holes that go through the foil to secure the slats. You do this by applying batten tape between the slats and the foil. Nail tape provides a water-resistant and airtight seal when attaching battens or ridges to foil.
