IMPORTANT FACTORS FOR WINDOWS[ ] DirectionIn order to be able to use the sun ideally, plan to haveyour windows facing mostly south, west or east. Largewindow surfaces facing south create good energybalance and bring light and life into your rooms. Plan toinstall sun protection systems right from the start to avoidoverheating your rooms. Additionally you can integrateinsect protection, too.[ ] Thermal insulationA house loses approx. 25 % of energy through its windows.Therefore thermal insulation is particularly important.This depends on frame material, impermeability andglazing. The statistical indicator for insulation propertiesof the window is the U value. The smaller the U value, thebetter the insulation properties of the window.[ ] SoundproofingNoise is unpleasant and can have a negative effect onhumans given the corresponding intensity and duration.Thus choose the correct glazing, frame material andimpermeability.Soundproofing of windows is measured in decibles (dB).The higher the dB value, the better the soundproofingproperties of the window.[ ] ImpermeabilityWindows are an important component of the outside walland have to withstand driving rain and wind-load. The importantfactor is the impermeability or air tightness of thewindow. This is indicated through the joint permeabilitycoefficient, called the “a value”. The smaller the “a value”,the higher the impermeability of the window.[ ] Burglary protectionAn experienced burglar can unhinge a window sash injust ten seconds. To prevent this Internorm offers highsecurity as standard. For additional security Internorm offersversions of safety class WK1 and WK2 with unhingeprotection, special locking parts, locking mechanismpoints etc. Fix-O-Round Technology ensures that theglass pane is connected to the sash frame on all sides.Unhinging the pane is therefore almost impossible. (seepage 13).[ ] Energy savingThe correct windows can help you considerably to saveenergy. Internorm therefore offers the best windows withthe most sophisticated technology and optimum thermalinsulation and soundproofing. With corresponding glazingyou can additionally achieve low energy or passive housestandards. Thus you can save on heating costs andimprove your living environment.[ ] Installation/FittingProfessional fitting of windows and doors is required forperfect functionality and long-term usability. Thermalloss can occur especially in the connecting area to thebrickwork resulting in condensation and mould. Thereforefitting should only be carried out by trained personnelsuch as your Internorm distribution partner. He can guaranteeyou installations according to the most up-to-datetechnology, compliance to the standards – such as theRAL installation – and observance to the structural-physicalprinciples.[ ] Correct VentilationInternorm windows offer superb thermal insulation andhigh impermeability. This prevents cumbersome draughts,saves heating costs and keeps out disruptive noise.Therefore you should systematically air your rooms.We recommend several times a day to have a 5 minute“complete airing session”. The room temperature willdrop for a few minutes, but the heat storage areas ofwall, ceiling and floor will not. Fresh air will warm up againquickly and energy loss is minimal.
