Usage
Vapor-permeable underlay for roofing. Used as a protective layer against moisture (liquid water penetration, Wind-blow snow). The product is laid directly over the plywood or solid support, parallel to the eaves with minimum 10cm (4 inch) overlapping and the printed side to the roof. The underlay is fixed to the plywood with roofing nails or nails with plastic cap.
Features
Linopore UV+: the patented UV protection against aging
The sun’s ultraviolet rays, with wavelengths of between 10 and 80 nanometers, attack the bonds of the polymer chains. That is the reason why roofs suffer early when inferior sarking membranes are used. MASTERPLAST produces the microporous membrane named Linopore UV+ which also called HALS (hindered amine light stabilizers) protect these layers against aging, independent of their thickness and color.
Thus, even after an aging test at 100°C, it retains 80 percent of its tear resistance and tensibility. Just compare that to the EN 13859 norm, which detects the durability after UV exposure and heat aging at only 90°C.
MASTERPLAST inline produces the polypropylene fleece with widths of up to 5.60 meters, coating it with a polypropylene film. This patented functional layer, with its sd value of 0.02 meters, makes it highly water vapor permeable as well as resistant to water penetration. Moreover, when the roof materials are dark, it gets hot on a roof. Therefore, Linopore UV+ make sure the sun will hardly do any harm to the roof. Also, the sarking membrane’s coating ensures increased UV stability and heat resistance, making it ideal for dark roofs and as a makeshift roofing.
