Ekstrands' inward-opening windows are also available with aluminum cladding on the outside. The window has the same properties and functions as our wooden windows. Ekstrand's aluminum cladding is more advanced compared to other products on the market. The profile is insulated and glued to the glass to break thermal bridges and increase burglary protection.
A high-performance window with double or triple sealing strips, adapted for both private villas and apartment buildings where extra high demands are placed on the climate shell. The window can be integrated into the wall with over-insulation of the frame, this increases the thermal insulation capacity and provides optically narrow profiles. The smart German fitting technology means that the sash can be folded into a ventilation position without having to move flower pots. The sash is 3D adjustable, has break points on all four sides and built-in microventilation. A wide range of options means that the window can be adapted for both classic and modern architecture.
The window can be integrated into the wall with over-insulation, U-value calculations and drawings for more installation situations can be provided.
Inward-opening wood/aluminum windows are windows for both villas, apartment buildings, renovations and new construction. Our collaboration with leading hardware manufacturers, a wide range of options and great dimensional flexibility give the architect full freedom to create a window for your specific purpose.

System 92 wood/alu
The wood/aluminum window has a triple-glazed window with a U-value of 0.5W/(m²K) as standard. The U-value of the entire construction is 0.78W/(m²K).
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.
Note: The opening systems below are shown with standard profile.
Fixed window
Fixed windows are suitable where there isn't a need to open the window. They can be delivered in considerably larger dimensions than opening windows. A fixed window consists only of a frame and allows more natural light to come in than through opening windows. Keep in mind that the fixed and opening windows have different optics. This makes the alignment of the glass, and in some cases astragals and glass dividing bars, differ. Fixed windows can also be delivered as gable windows in curved angles. Note that fixed windows are not mounted with screws, but with mounting brackets. These are not included in the delivery.
Side-hung inwards opening window 1-sash dreh-kip
An inwards opening side-hung window with a ventilation function and micro-ventilation in the fitting. The construction makes it possible to manufacture the window in larger measurements than what is normally possible with opening windows. Can be delivered as 2-, 3- and 4-sash windows.
Side hung window 2-sash dreh-kip / dreh
An inwards opening side-hung window with a ventilation function and micro-ventilation in the fitting. The construction makes it possible to manufacture the window in larger measurements than what is normally possible with opening windows. Can be delivered as 2-, 3- and 4-sash windows.
Inwards opening window bottom-hung kip
Bottom-hung and inwards opening windows for spaces or sizes where the side-hung tilt and turn windows won’t fit. For example, basement windows or windows in small rectangular shapes. The ventilation function is a smart solution that disconnects so that the sash can be opened inwards when cleaning.
Inwards opening balcony door dreh-kip
Inwards opening balcony door with ventilation function and micro-ventilation in the fittings. As standard it’s delivered completly glazed. It’s becoming more common with this type of balcony doors because they let in more light. There are optional insulated fillings and astragals in several variations. Balcony doors are supplied in most widths and heights. Different handles with locks and safety espagnolette WK2 are available options.
Inwards opening double balcony door dreh-kipp / dreh
Inwards opening balcony door with a smart ventilation function and micro-ventilation in the fittings. Balcony doors are available in most width and height measurements and customized according to customer requirements.
We offer a wide range of quality handles and fittings. The handles shown are available in most finishes or colours. However, not all are shown in all the colours they are available in. Click on the respective handle to read more.

We have several different types of astragals in our range to be able to adapt all window systems to each customer's specific wishes.
