Frequently asked questions
Choosing your brand well
Which window brand is the best? +
There is no single answer: it all depends on the material you are after, your budget and the look you want. A brand that excels in aluminium is not necessarily the best in PVC. We point you in the right direction based on your project.
Does the profile matter more than the brand? +
The profile (its depth, its insulating chambers) and the quality of the fitting weigh as much as the name on the invoice. A good brand badly fitted loses all its benefit.
Do you fit brands other than Profel? +
Yes. Profel is our Expert partner, but we fit several profiles so we remain free to advise you objectively.

Worth knowing
Brand, profile or fitting: what really matters?
We are often asked “which brand is the best”. The honest answer comes down to three factors, and the brand is only one of them. The chosen profile (its depth, its number of insulating chambers) makes the performance vary as much as the logo on the frame.
Then comes the fitting: an excellent window badly fitted loses its weathertightness and its warranty. That is why we stay independent — our interest is to steer you towards the right product + fitting pairing, not to sell one particular brand.
“The best window is the one that matches your budget, your façade and your standards — fitted well.”
