Riwega USB breathable barriers and membranes Superior Line

Riwega USB breathable barriers and membranes In Germany, where rain is a frequent and serious problem, ZVDH (Zentralverband des Deutschen Dachdeckerhandwerks - German Association of Roofers) has established the following categories for under-tile membranes: - Unterdachbahn (under-roof membrane): impermeable membrane that must guarantee impermeability in any situation, even when the roof is not able to guarantee impermeability to heavy rain (e.g. due to lack of slope or particular roof shapes). Can be used up to a minimum slope of 5° (8.7%). In this category the best products are those which...

To sum up: the natural physical phenomenon that seeks to balance humidity levels is the key to the permeability to water vapour: vapour which passes through materials does not cause any damage; vapour that collects inside materials may cause: • condensation to form inside the structure • a reduction in the insulating performance of the materials • deterioration of the materials over time • the formation of mildew and funghi which are detrimental to human health The concept of breathability of breathable layers and membranes can be described as: "The ability of breathable layers and...

Instructions for installing Riwega USB barriers and membranes - pitched roofs Riwega USB barriers and membranes are installed starting from the bottom, parallel to the eaves. They are mechanically fixed using nails or staples along the upper overlapping line, or glued with 3 strips of butyl adhesive in cartridge USB SIL BUTYL, or two-sided butyl adhesive tape USB TAPE 2 BU or USB TAPE 2 BU/CO. Depending on the roof slope, the overlap of the Riwega USB breathable layers and membranes must not be less than 10 cm for slopes of or more than 30% (16.7°) and 20 cm for slopes of less than 30%...

On ridge lines or valleys, the strips of the Riwega USB breathable layers and membranes emerging from the two pitch sections are laid on top of each other with a minimum overlap of 20 cm. The overlap must be sealed using suitable adhesive strips (monoadhesive acrylic tape with polyethylene backing USB TAPE 1 PE, two-sided acrylic adhesive tape USB TAPE 2 AC, acrylic based adhesive in cartridge USB SIL). If laying Riwega USB breathable layers and membranes on top of a second ventilation plank, stop at a distance of about 5 cm before the ridge or valley in order to allow the air to flow, thus...
