| Use advice for data set | Scope: Productline LGI - frame extension; manufactured by VELUX in Hungary for sale in Europe. Declaration according to ISO 14025 and EN 15804 describing specific environmental performance of the construction product. System boundary: Type of EPD: Cradle to gate - with options. The following life cycle stages were considered: Production stage A1-A3: Consideration of the production of raw materials (wood profile and steel) and their processing (specific energy data: electrical energy from the national residual mix and thermal energy from natural gas, oil and biomass); transport of major materials to the manufacturing site; assembly of semi-finished products to the final product; packaging material (including waste paper input for paper and cardboard). End-of-Life stage C1, C2, C3: C1: a manual demolition is assumed, resulting in indicator value "0". C2: For the transport to EoL by truck a distance of 50 km is assumed. C3: A scenario for the incineration of wood in a waste incineration plant (WIP) is assumed; metals are assumed to be recycled. The EoL-Scenario does not assume waste to be disposed of on a landfill site. Module C4 is declared as"0". Benefits for the next product system D: Resulting electrical and thermal energy from the WIP, avoiding the generation of electricity and heat via fossil fuels, is considered. The amount of metals after the reduction due to the net-flow calculations is sent to a recycling process. The effort for recycling, as well as the benefit for the regained metals are declared in module D. Contribution of waste flows is considered in the modules where they occur. | ||

| General comment on data set | The frame extension LGI consists of four pieces of frame made of laminated pine wood to be fitted into the rebate of a VELUX roof window, increasing the total frame height by 60 mm or 90mm. To ensure a sufficient ventilation flow under the roofing material, roof constructions are often provided with high counter battens. The increased distance from the top of the battens to the insulation level leaves the roof window far away from the insulation. To compensate for this, you can fit frame extension LGI into the rebate of the roof window from the inside, increasing the total frame height and letting the window reach the insulation. Installation angle Frame extensions can be installed regardless of roof pitch in all roof constructions. | ||

| Technology description including background system | The manufacturing at the VELUX site mainly covers processing steps of semi-finished materials purchased from suppliers like profiles and pre-fabricated films, foams and sheets. Technical data: The Declaration of Performance including relevant technical specifications and test methods/test standards can be downloaded from the website www.velux.com/ce-marking. Declared unit: The declared unit is 1 m related to a reference window, that the frame extension is installed in connection with. The declared unit is based on the representative product measuring 0.78 m x 1.178 m. The product LGIis manufactured in Hungary. | ||
