Folding patio wood

U-value
from 1.1

Our folding windows are as well insulated as ordinary windows. Strong constructions and advanced fitting systems mean that large areas can be opened up.

With Ekstrand's 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. Can also be delivered with aluminum cladding on the outside, see Folding windows wood / aluminum.

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 with aluminium cladding on the outside. See Folding patio wood/alu

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.
