The secret of Finstral’s success.
Why are our windows so special? Because we at Finstral do everything ourselves. Only those who think a product through from beginning to end can continue to ensure its full development – this idea has underpinned our thoughts and actions for the last 50 years. That is why we offer everything from a single source, from the development of profiles and in-house production right through to finished installation. This allows us to offer individual solutions and maximum design freedom for all of our windows, entry doors and conservatories. Only in one regard will we brook no compromise: with our high-quality, perfectly insulating PVC cores.
