U-value: what does thermal insulation mean for your building project?
Sustainable homes and buildings are the only way forward. A significant factor to measuring energy efficiency is the U-value. The lower it is, the better the thermal efficiency or insulation.
Rising energy costs and growing sustainability awareness have considerably increased the focus on a building’s energy performance. Efficiency standards – imposed and often made stricter by regulation – are a major indirect driving force behind enhancing the comfort level of a project. Thanks to an optimal U-value, you not only save energy, you also increase your quality of life.
U-value, formerly known as K-value, is used in the construction industry to indicate to what extent a material is thermally insulated. The lower the U-value – or, “thermal transmittance” – the higher the heat resistance of a material – thus, the better the insulation. Because the thermal transmittance is determined by the profiles of windows and doors, plus the glass, the U-value of both components should be considered for the joinery of an aluminium construction.
ConceptWall 50 is a curtain wall façade and roof system that offers incredible building speed, unlimited design freedom and exceptional performance. The stick façade’s highly insulated variants achieve energy efficiency up to Passive House levels.
