U Values windows


Basically the lower the u-value the less heat will be lost through the glass. The standard u-value achieved with Nordvest products will surpass the accepted UK Regulation as a much greater level of insulated value is required by Norwegian Regulation.

On New Build properties the placement and styles of the doors/windows can have a great effect on the level of energy consumed within the property. A little thought at the design stage can save future costs on energy. Always going for the lowest U-value may not be your best solution as products on a south facing elevation may be better equipped with solar controlled glass to allow a more pleasant quality of living in the property.

We have u-values to suit all situations from standard 1.4 W/m²K right down to 0.6 W/m²K triple glazed which is suited for the Passive House market.

U-values shown on all our offers are calculated through the complete product and not just the centre pane of the glass.
