With their charming timber interiors and weather-resistant, durable external aluminium cladding, wood-alu tilt and slide doors contribute in numerous ways to both design and functional performance. This is reflected in their impressive u-values. Measured in W/(m²k), u-values, also known as the heat transfer coefficient, determine the amount of heat lost each hour per square metre. The lower the value, the better as less energy is lost through the product. Below you will find the Ug value of the glass, Uf value of the frame as well as the total Uw value with various seal options for our different profiles.

With a parallel slide & tilt door made of wood-alu, the Uw values are calculated using the individual U values of each window frame and glazing as well as the heat loss along the edge of the glass. For the sake of comparison, a standard window size of 1230 x 1480 mm is usually used for the calculation, but it can generally be assumed that a larger window will result in a lower value.
A thermally separated edge seal along the insulating glass - the so-called "warm edge" - further improves the thermal insulation of the entire door.
The heat transfer coefficient of a parallel slide & tilt door made of wood-alu determine whether a parallel slide & tilt door can be classified as suitable for passive houses. Energy savings not only protect the environment, they also make an immediate difference on your energy bill.
The difference between a Uw value of 3.5 and a value of 0.83 can make a difference of more than 1000 litres of heating oil per year for an area of 30 m².
