Wind and rainproof

Weather generally has a detrimental effect on windows and outside doors. Wind, storms and rain require a reliable design, tested joints and expert assembly.


Don’t give bad weather a chance!

Sealed against wind and rain – a standard feature of all our window and door systems. A very important one, however.

The film shows how your Finstral window protects you from inclement weather.

Stable construction

We bond all of our glazing directly onto the windows. This bonding ensures high dimensional stability, even in very bad weather. Steel reinforcements for very large glazed areas make the windows even more robust.

Proven construction techniques mean that Finstral systems have outstanding tightness. A stable fit will ensure reliable functioning for years to come.
