SUSTAINABLE WINDOWS
How to construct a wooden window that lasts? The answer is that you do the opposite of everyone else. Ekstrands turns the entire industry upside down with a unique window construction for Scandinavia, which goes against the way everyone else designs their windows. How is this possible in the 21st century? As we see it, it can only be explained by tradition and that in large-scale production, greater emphasis is placed on finding cheaper solutions instead of designing a product that is sustainable for the customer in the long term. We will briefly explain some of the most important differences between our windows and others. If a wooden window is to last a long time, it must be constructed in such a way that the water is kept out of the construction, that the wood can breathe and maintain the right moisture content over time. Ekstrands uses 3-layer glue-lam wood, no risk of knots bleeding or cracks in color due to the twigs.
High security windows
If the glass strip is mounted on the outside, it is a capillary trap, the water is sucked in capillary between the sash and the glass strip, elevated moisture content in the window base occurs, with color flaking and sometimes rot as a result. Ekstrands does the opposite, instead mounting the glass strip on the inside where it is protected. This also has another advantage, the thief can not remove the strip externally and remove the glass pane.
Impregnation & drainage
Constructive wood protection is a key word in our organisation. This means that we manufacture profiles and details in such a way that the moisture cannot accumulate or be absorbed capillary in the wood. An example is Ekstrand's drip nose under which window panes are mounted, for natural drainage. Another example is that impregnation and painting of profiles takes place after processing, before final assembly and glazing. Impregnation with an environmentally friendly linseed oil alkyd emulsion and diffusion-open paint.
Burglary protection
We completely glue the glass on the inside and outside with high-quality silicone. It is much safer than using a regular rubber strip.
Windows in different shapes
Free forms are not used as often as in the past, the price picture is probably one of the reasons. Ekstrands can today offer a wide and very competitive range of windows in free forms. Our flexible production facility means that the products today are very affordable.
Our free forms are almost unlimited, round, semi-round, 2-sash, 3-sash, etc. Note that many variants of free forms can be delivered with our smart ventilation fittings.
Of course we also manufacture windows with broken angles, these can also be delivered in the Sverige104 window profile.
