Folding patio aluminium

  • U-value
    from 1.1

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

Our windows can be delivered in different window systems. See the options below.

  • System 78 wood/aluminum

    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.

  • System 68 wood/aluminum

    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.

The flexibility is great and all windows are manufactured in millimeter sizes according to your wishes. This window system has the following different opening variations.

Astragals and the design of astragals change the character of a property. It is important that the size and number of astragals on each window are adjusted so that it looks good. Ekstrands manufactures all types of astragals, horizontal, vertical and diagonal crosses. We have several different types of astragals in our range to be able to adapt all window systems to each customer's specific wishes. If there is uncertainty about the design, we will produce a drawing of the window with different astragals.
