EPD: Wooden roof window, double glazed, 41.88 kg/m2 (VELUX Group)

The VELUX wooden roof windows are skylight window products for sale in the European market. The product family covers a range of product varieties as specified in the table below. All windows have a wooden frame/sash. Some windows can be opened (venting), while others cannot be opened (fixed). In addition, the windows consist of 4 different hinge-functionalities (pivot-hung, top-hung, side-hung, bottom-hung). The handles and handlebars are made of aluminium, while the hinges are made of steel (galvanised, stainless). Some of the window varieties can be used in conjunction with electric or solar window operators for automatic opening and closing, while other windows are opened and closed manually. The calculations are based on the representative window type named GPL. In the LCA, the GPL was assessed to be a conservative choice for a representative window type. The glass panes are with double glazing (2-layer glazing) and different glass configurations are covered by the EPD. The glass thickness ranges from 8 to 10 mm. The glass panes have cavities filled with Argon gas. The EPD is based on an average of the included glazing unit configurations. The included glazing unit configurations are: 50/51, 70, 70 Q and 76. Only the window modules are included, which means that any applied window operators, installation products, accessories, etc. are not part of the EPD. These are available as separate EPDs, that can be used in combination with this EPD.
