Passive House Roof System

组件id: 1370rc03
制造商: VEDAG (China) Trade Co., Ltd.
种类: 屋顶 
结构种类: 固体 (TICS) 
窗户: Analysis was undertaken for two separate roof window types; the 'Composite Glazing - öffnungsfähiges Glasoberlicht' from Glas Trösch (Uw = 0,94 W/m²K with Ug = 0,75 W/m²K) and the 'Nauheimer Lichtkuppel' from Hans Börner GmbH & Co. KG (Uw = 0,68 W/m²K with Ug = 0,89 W/m²K), based on dimensions 1,5 x 1,5 m. The calculations undertaken demonstrate that the window installation locations are suited to the cool-temperate climate, with no risk of surface condensation and subsequent mould growth. 
气密度: Air tightness is achieved by the following procedure: Roof windows are to be constructed with permanently elastic + tight materials. Internal surfaces are to be plastered over the entire surface; internal surfaces in lightweight construction are to be covered over the entire surface with continuous, airtight membranes; windows are to be properly connected with suitable airtight window connection membranes or profiles. 
图示: The Passive House Institute has defined international component criteria for seven climate zones based on hygiene-, comfort- and affordability criteria. In principle, components which have been certified for climate zones with higher requirements may also be used in climates with less stringent requirements. This use might make sense in certain circumstances. 
气候区: 冷,温度
备注: The VEDAG Roof Waterproofing System ensures both comprehensive weather proofing and Passive House standard thermal protection. The system is intended to be used with reinforced concrete construction with EIFS and comprises an exterior insulation finishing system of G-EPS (0,033 W/mK) installed using compatible adhesive materials. VEDAG membranes are applied on top of the insulation to form the weather barrier. The system has been assessed according to the Passive House Institute's criteria for roof systems and has been validated as suitable for Passive House projects in the cool-temperate and warm-temperate climate zone.
