Our folding windows in wood/aluminium are as well insulated as ordinary windows. Strong constructions and advanced fitting systems mean that large areas can be opened up.
With Ekstrands' folding window, you can open up more than five meters of the facade. Our folding windows are delivered from 1.6 meters wide up to 5.5 meters and 2.5 meters in height. The frames are pushed on the inside and a number of different opening options are adapted to the dimensions. See some options for opening options under the System tab. Just like balcony doors, folding windows are supplied with full glass as standard. Options in the form of fillings, posts and various astragal alternatives mean that the folding sections can be adapted as needed. Open up the wall and turn the interior into a outdoor area when the weather allows.
Our collaboration with leading fittings manufacturers and a wide range of options gives the architect full flexibility to create a window for your particular purpose.
Our folding patio windows are also available in wood without aluminium. See Folding patio wood
There are several different options to choose from at Ekstrands, here we show some of the most common.
An insect screen that is very practical and takes up minimal space when not in use. The color of the profile is white RAL 9010. On balcony doors, the insect screen is pushed sideways. Choose between 4 different nets: Plastic fiberglass is standard (gray net), Clearview (black net), Pollen reducing (black net), Blackout (white fabric)
Aluminum sill with broken cold bridge that allows low installation, order dimensioned drawing to project the installation situation. Note that the threshold has no drainage, in extremely exposed situations or where large amounts of melting snow are at risk, a standard threshold should be considered.

Wood/Aluminium can be delivered with a triple-glazed window and then has a U-value of 0.9W/(m²K). This provides slightly better thermal insulation and edge zone temperature, but poorer daylight transmittance and solar energy transmittance (G-value) than double-glazed windows. Which glass to choose depends on your needs.
Ekstrands wood/aluminum window with a double-glazed window has a U-value of 1.2W/(m²K). The window is classified as energy-efficient and is in many cases good enough. Choosing the right glass and U-value is complex, a double-glazed window has, for example, better daylight transmittance and solar energy transmittance (G-value) compared to a regular triple-glazed window. What to choose depends on what you prioritize, energy saving, comfort, sun protection, etc. Ekstrand tailors each window to the customer's needs. Contact us and we will tell you more.
