UNIGLAS Tender Specifications Special contractual conditions: Insulating glass elements The insulating glass elements used and integrated must be CE-certified, and insulating glass units in Germany must be Ü-certified in accordance with Bauregelliste A, Part 1, Annex 11.10. Glass Clear, transparent base glass with maximum colour neutrality must be used. Tests Only insulating glass produced by manufacturers that undergo a voluntary third-party inspection performed by a test institute recognised by the GMI, KOMO or a corresponding Austrian body may be used. Evidence of the last two test reports must be submitted upon request. Glass dimensions and applicable standards EN 1991 For construction projects in Germany, the necessary glass thickness must comply with technical regulations for the use of glazing with linear supports (TRLV) and the relevant applicable technical regulations of the German Institute for Building Technology (DIBt) and/or comply with DIN 18008 and any relevant building standards. The established building regulations and standards in each respective federal state shall take precedence. In Austria, dimensioning shall observe ÖNORM B 3716 in conjunction with the relevant applicable national standards and legal provisions. For construction projects in other countries, the local established building regulations and standards shall apply. Within the jurisdiction of European standards, the actions in accordance with the corresponding national editions of EN 1991 must be applied. If the EN 1991 standards have not yet been implemented by building authorities, the corresponding national standards must be observed. The building height is m above sea level, in wind zone, inland, postcode/zip region: Dimensions of the building b x l x h in m Exterior walls are not permeable. DIN 1961 The general contractual terms and conditions for the execution of construction works (VOB/B) and the general technical contractual terms and conditions (VOB/C) shall apply in their latest versions. ÖNORM A 2060 and ÖNORM B 2110 The general provisions of a contract for services and construction ÖNORM B 2227 Glass works - work contract DIN 4108 The thermal transfer coefficient for glazing (nominal value U g -value in accordance with EN 673) is specified in the performance description. For exchanging glazing panels, the dimensioning U-value UBW in accordance with DIN 4108 must be considered, taking into account any necessary allowances ΔUg. DIN EN 20140 The test value of the evaluated sound insulation value R w,p for insulating glass is requested in the performance description. DIN 18361 For roof glazing, laminated safety glass must be integrated by derogation from VOB/C DIN 18361.
Regulations Technical regulations must be observed for the glazing design. The most important regulations are listed below and are valid in the corresponding current versions. - UNIGLAS glazing guidelines, latest version - Guidelines of the Institute of Window Technology, Rosenheim - Guidelines of the Institut des Glaserhandwerks für Verglasungstechnik und Fensterbau, Hadamar - Passive house suitable components of the Dr. W. Feist Passive House Institute, Darmstadt - Standards and technical regulations introduced by building authorities - Guidelines for assessing the visual quality of glass for the building industry, issued by the Technical Advisory Board of the Institut des Glaserhandwerks für Verglasungstechnik und Fensterbau, Hadamar and by the Technical Committee of the Bundesverband Flachglas e. V., Troisdorf *) - Pamphlet 006 of the Bundesverband Flachglas e. V. "Visual guidelines for systems in gaps between panes" issued by the Technical Committee of the Bundesverband Flachglas e. V., Troisdorf - Pamphlet 006 of the Bundesverband Flachglas e. V. "Guidelines for assessing the visual quality for systems in insulating glass units" issued by the Technical Committee of the Bundesverband Flachglas e. V., Troisdorf *) in Austria shall apply contrary to the "Guidelines for assessing the visual quality of glass for the building industry" ÖNORM B 3738 Plate glass in the building industry - Insulating glass - Requirements in visual quality Technical data - The technical data and functional values indicated are based on information from base glass manufacturers and were determined on the basis of each applicable product standard. - The functional values determined by test certificate refer to test pieces in the standard dimensions intended for the test. - Corresponding deviations from the declared values occur due to the reliable tolerances of incoming products. - Lighting and radiometric parameters must be determined in accordance with EN 410. - The thermal transfer coefficient Ug value must be calculated with a validated programme in accordance with EN 673. The validation must come from a notified body approved by the DIBt and/or one listed in the NANDO list. Test certificates in accordance with EN 674 or 675 shall only be approved in justified, exceptional cases due to the insufficient comparability of values in accordance with EN 1279-5.
