How to Choose the Right Windows – Tips and Buyer's Guide

To simplify the decision in favour of our windows and doors, we offer three product groups. Basic range with a better price/performance ratio and all the requirements for tax deductions. The medium range has higher thermal and acoustic insulation thanks to the third seal. The Topclass range has an even higher thermal insulation thanks to the 80 mm thick profiles. All three categories can be fitted with single-chamber and double-chamber glass. Basic, Medium and Topclass carry the same burglar-restricting hardware as standard, and adopt the same technology as the glass.
