Access roof lights
Technical purpose of product or process Access roof lights enable fast, safe and easy access to the roof to carry out repair and maintenance works. They illuminate the interior and can be opened to ventilate the room. Access roof lights are designed for uninhabited lofts with the interior temperature similar to the outdoor one. The frame is made of vacuum impregnated wood, while the sash is made of powder coated aluminium profile. The flashing is an integral part of the access roof light. Access roof lights include several product varieties: - WLI is a side hung window. It is equipped with the 4-8-4 (or occasionally 3-8-3) glazing unit. It can be installed in left or right opening version. The applied turn limiter holds the sash stable and prevents against accidental closure. The lower part of the access roof light comes with a specially shaped profile which covers the frame and prevents slipping while getting onto the roof. - WG comes with a top hung structure, while its sash is opened upwards. It is available in two versions: * WGT with a single 4 mm thick glass * WGI with the 3-8-3 glazing unit WGI is equipped with a gas spring which makes opening easier, holds the sash stable and prevents it against accidental closure. - WS features a top hung structure. Semi-circular polycarbonate dome opens upwards up to an angle of 180°. The material used demonstrates increased resistance to weather conditions and provides protection against UV radiation. Available in three different types, depending on the roofing material applied: - WSS with flashing for flat roofing material - WSZ with flashing for corrugated roofing material - WSH with flashing for high-profile roofing material - WGU, WGU-X is a side hung window. It comes with the 3-8-3 glazing unit, a gas spring that holds sash in the open position and a profile that covers the lower part of the frame. WGU-X additionally has a vapour-permeable flashing. - WGB comes with a top hung structure, while its sash is opened upwards. The upper part of the frame is arch-shaped. It is available with the 4-9-4 glazing unit. WGB has a gas spring that makes it easy to lift the sash and holds it in the open position preventing accidental closure. The WGI access roof light sized 46 x 75 cm and WSZ access roof light sized 54 x 75 cm were adopted as representative windows. Composition and percentage of input materials of access roof light WGI and WSZ and packaging materials produced by FAKRO PP Sp. z o.o. Detailed parameters of access roof lights are specified in their Declarations of Performance, which can be downloaded from the FAKRO PP Sp. z o.o. website: www.fakro.com
General comment on data set The data selected for LCA analysis originates from ITB-LCI questionnaires completed by FAKRO PP Sp. z o. o. using the inventory data, ITB and Ecoinvent database v. 3.10 and KOBiZE. KOBiZE data is supplemented with Ecoinvent v. 3.10 data on the national electricity mix impact where no specific indicator data is provided. No specific data collected is older than five years and no generic datasets used are older than ten years. The representativeness, completeness, reliability, and consistency are judged as good. The allocation rules used for this EPD are based on general ITB PCR A v. 1 .6. Production of access roof lights is a line process conducted in the manufacturing plan located in Nowy Sacz (Poland). All impacts from raw materials extraction and processing are allocated in A1 module of EPD. Impacts from the FAKRO production were inventoried on the annual production volume expressed in kg. Water and energy consumption, associated emissions and generated wastes are allocated to module A3. Energy supply was inventoried for whole production process. Packaging materials were taken into consideration. The life cycle analysis (LCA) of the declared products covers: product stage – modules A1-A3, end of life – modules C1-C4 and benefits and loads beyond the system boundary – module D (cradle-to-gate with options) in accordance with EN 15804 + A2 and ITB PCR A v. 1.6. Energy and water consumption, emissions as well as information on generated wastes were inventoried and were included in the calculations. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with EN 15804 + A2, machines and facilities (capital goods) required for the production as well as transportation of employees were not included in LCA.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
