As well attaining the utmost performance in terms of insulation, protection and security, your fixture must also be able to retain these properties over time.
In order not to waste time and money, it is advisable to buy a good product at the outset that will meet all your expectations in the coming years. The value of the frames and all the accessories, but especially the material from which they are made, are vital elements in the durability of the new window. We therefore recommend that you choose the fixture that can give you the most in terms of performance for the longest time possible.
