High-quality aluminium – with the insulation value of PVC.
Do you want an innovative aluminium window? One with narrow frames but first-class insulation values – and maximum freedom in choosing colours and details? Then you’ve come to the right place. Because Finstral has re-invented the aluminium window. The core always contains PVC to give the best insulation values. And because our aluminium windows are modular in design, there is a wide variety of frame forms and fittings available for you to compose your individual window. Only we offer this. Because at Finstral we make everything ourselves: developing frame profiles, producing insulation glass, setting installation standards. Come and see for yourself.
