Questions and answers
Frequently asked questions
What is a thermal break?
A plastic insert separates the inner and outer parts of the aluminium profile, so the cold doesn't pass through the metal. This is what makes aluminium windows warm.
Which system should I choose?
It depends on the size of the openings, the insulation you want and your budget. During the survey we'll suggest two or three suitable systems with prices.
Can aluminium windows have a wood colour?
Yes. Besides RAL colours there are wood finishes and anodised coatings.
