Insulating glass, triple glazed, coated

Product Triple glazed insulation glass units are sealed units that comprise three sheets of flat glass separated by two 16 mm spacer strips, and are sealed around the edge. One glass is selective coated and the two other glasses are clear glass. All glasses have a thickness of 4 mm. The mass of 1 m² product is 31.34 kg.

The units are available in a wide range of dimensions and configurations. This EPD covers the units with 3 pcs of 4 mm glasses with argon gas filling. One glass is coated and the 2 other ones are clear. The products can be produced with a wide size range, starting from 0.1 m² up to 6 m². A typical size is about 1 m². The product is used in windows and doors. Packaging and transportation The insultating glass units are packed into specialised racks which are re-used numerous times. The racks are circulating between the insulating glass producer and the window and door producer. The insulating glass units are delivered mainly to the window and door producers ready for installation. The Insulation glass units fulfill the product standard EN 1279-5:2018 Glass in building. Insulating glass units. Part 5: Product standard. The units are CE-marked according to this standard and according to the AVCP class 3. The insulating glass units have also a FI-product certificate issued by the certification body Inspecta Sertifiointi Oy. The glass used in the units fulfills standards EN 572-9:2004 Glass in construction. The glass also complies the following standards: - EN 572-1 Glass in construction - Basic products: basic soda-lime silicate glass – Part 1: definition and general physical and mechanical properties; - EN 572-2 – Glass in construction – Basic products: basic soda-lime silicate glass – Part 2: Float glass.

The geographical representativeness is good, because the environmental impact information is partly from Finland and partly from Europe. Three product specific EPD information are used for the main raw material components of the product. The technical representativeness is good, because there exists only one production process and the environmental impact per functional unit does not change, when the size of the product changes. The time representativeness is good: the used Ecoinvent 3.6 database values are updated 2019, and the EPD calculation is based on the production year 2022. The overall data quality for this EPD can therefore be described as "good". All relevant process-specific data was collected in the internal controlling. In all possible cases, primary data from customers was used, which is of good quality. In addition, secondary data from the Ecoinvent database (2019, version 3.6) was used when no primary data could be supplied. The database is checked regularly and, therefore, fulfills the requirements of EN ISO 14040/44 (background data not older than 10 years). The background data meets the requirements of EN 15804+A2. The quantities of raw materials, consumables and supplies used and the energy were recorded and with this the material usage for the declared unit determined. The general rule that specific data from certain production processes or average data derived from specific processes must have priority when calculating an EPD or LCA, was adhered to. Data for processes over which the manufacturer has no influence were assigned to generic data/scenarios. When selecting these, the data set/scenario that most realistically represents the processes was selected. The production energy consumption per 3 glass insulating glass units is based on allocation, where the total energy consumption of the production site is allocated to 3 glass insulating glass with the factor, which is a percentage of this product type compared to the whole production of different glass units. The production volume is measured in m² of insulation glass units. As no country specific data on the benefits at the end-of-life was available, the Dutch Environmental Database (NMD) scenarios were used.

The unit is mounted at the window or door factory to the window to the wooden or aluminium frames, which are then transported the construction site for mounting into the building. Sometimes the insulation glass unit is transported directly to the construction site for direct mounting into the building.

The units will be mounted into window or door frames at the window production factory.
