Wood = maintenance
a plastic frame means worry-free enjoyment

Plastic frames are wonderfully low-maintenance. Just put a cloth over it when cleaning the windows and you’re done. At least, if you choose quality. Weru for example. Window frames, doors and sliding doors from Weru are beautiful and remain beautiful. The insulation is superior. The low maintenance costs make them more economical than wooden frames. And with wood look you can’t even tell the difference: perfect for classic homes.

Aluminum frames, window decoration and insect screens

Do we only have plastic frames, doors and sliding doors? No, you can also contact us for aluminum frames, facades and doors from Mondana. We also have custom window decorations and insect screens from quality brands KeJe and Verano. And even more plastic: the front doors from Polytec from Germany and very well-insulated plastic dormer windows, custom made here in the Bulb Region.

Many people think of plastic frames, doors and sliding doors as an unattractive product with a short lifespan that looks dull and faded after a few years. And painting is difficult, so then you’re stuck. Moreover, they think wood is simply much more beautiful than plastic. If we’re completely honest, we used to think that too.

But then we got to know Weru’s products. Just take a look around this site. We bet that within a few minutes you will think: ‘Gosh, this is actually quite beautiful’? Stylish designs, wood look, hundreds of colors, countless options and possibilities. And we haven’t even talked about sustainability yet. Because a Weru product is beautiful and remains beautiful. That is that famous German solidity.
That’s why: Ambra Frames Weru.
