Roof membranes

Waterproof and highly vapor permeable membrane

Product description

Roof membranes

Blachy Pruszyński offers original seals to prevent water, snow or other impurities for its roof profiles. Also, seals should be fastened under machining (ridges, windbreakers, windscreening lanes). The supplied seals have a shape corresponding to the sheet profile both for roof tiles and trapezoidal sheets.

Based on many years of experience and research, we can conclude that the condition for trouble-free use of the roof system is the use of an appropriate vapor barrier in combination with a high vapor permeability foil (FWK). The use of low vapor permeable films is being abandoned. Our company recommends the use of the highest quality materials, which allows for long-term trouble-free use of the roof. The role of the roof is limited to two basic functions: the roof must be airtight and aesthetic. The tightness condition may not be maintained if a poor quality membrane (or foil) is used or its installation is incorrect. Another important argument is that a roof built using a good quality membrane is simply cheaper and warmer, which is reflected in heating bills.

The Blachy Pruszyński company offers high-quality vapor-permeable films. As a standard, roof membranes are protected against UV radiation, for this purpose special stabilizing components are added to increase resistance to solar radiation. It should be noted that roof membranes cannot be exposed to direct sunlight for long periods of time, therefore it is recommended to close the roof as soon as possible. The durability of the membrane against direct sunlight is 3 months. Thanks to high vapor permeability, there is no need to create a ventilation gap between the membrane and thermal insulation. It should be remembered that the installation of the membrane should always take place in conjunction with the counter batten.

The technical parameters of the offered roof foils can be found in the leaflet.

Do you have questions?

Is it possible to make copper machining at the steel roof?

When using copper, be careful because copper oxides are very aggressive and cause corrosion of other metals. Therefore, on buildings, it cannot be combined with other metal species (copper enters into contact and causes electrolytic corrosion of other metals).

Why is the metal roofing sheets recommended for the renovation of old roofs?

This is directly related to its low weight. In the case of old roofs, the trusses of the renovated houses are often somewhat damaged by time. Therefore, it is safer to use a metal roofing tile, which weight oscillates at 4.7 kg/m2, than almost ten times a heavier ceramic tile than it. However, it is always worth verifying the condition of the roof truss, with a specialist and make sure that it does not require renovation or replacement. In such cases, the safety of residents or building employees, as well as the assembly team, is always a priority. In most situations, however, the condition of the structure without major problems allows the use of roof tiles, while the use of ceramic tile would not be possible.

Can you use an angle grinder when cutting sheets?

Modern roofing exclude the use of angle grinders for cutting. The use of this method of cutting the material is associated with the loss of warranty.The angle grinder during operation and cutting produces very large amounts of heat, which in turn damages the edges of the sheet, as well as the coating covering it. In addition, the filings extracting during operation blend into the surface of the blades, additionally creating potential corrosion outbreaks.The right way of cutting sheet metal is to use automatic jumps (so -called Nilerler) or hand scissors. They use the mechanical force to cut the sheet, without exposing it to high temperature jumps. In addition, it is worth remembering that after cutting it is good to train cut places with dedicated protective varnish or special paint.

Does the roof require maintenance?

Yes, each roof requires periodic inspections to check if there have been any damage. Most of the products offered by Blachy Pruszyński have various types of specialized coatings available (covered by the warranty), increasing the life and durability of sheet metal. Maintenance consists mainly in removing the deposits and chimney dust, which left for a longer period of time can lead to sheet metal damage. Particular attention should be paid to places around chimneys that are sensitive due to more demanding operating conditions. If during the coverage inspection, local damage to the paint coating will be noticed, paint corrections should be made. In such a situation, the best solution is to use dedicated gloss paints tailored to a given coating. Such paints are in a stringent offer of Pruszyńska sheet and it is strongly recommended to use company products, recommended for a given coating.
