Windows made from wood, aluminum and much more

Windows have to withstand a lot. That’s why we only work with PVC with sufficient hardness, elasticity, as well as resistance to heat and cold to deal with hot summer days and stormy fall or cold winter nights. In addition, an internal steel reinforcement ensures maximum durability.
We only aim low when it comes to prices. Our PVC craftsmanship comes at a price at which it would be a shame to compromise.

UNILUX PVC windows


The German EnEV energy conservation ordinance requires that the heat transfer value of windows must not exceed 1.3 W/m²K. With IsoStar and a total glass thickness of 48 mm, this figure is a mere 0.73 W/m²K. And you even save twice: when you first purchase it, and then, day after day, night after night. That’s because this window keeps the heat where it belongs: in your house.


No compromise! Our IsoPlus model sets the bar high – high insulation values, high dimensional stability, high security. Only the price is pleasantly low. Like this, you get a lot of window for your money, and at the same time, you can bring your design ideas to fruition. IsoPlus comes not only in a wide range of colors and wood decors, but also with two different view designs. This gives you the certainty that the window will blend harmoniously into modern as well as classic architecture.

Give your home some new freedom.

Whether it’s a green garden or an urban skyline – with the IsoStar HStec and IsoPlus HStec lift-and-slide systems, you can integrate the outside world into your living environment thanks to their generously-sized glass surfaces.
