04Window brands & systems

Recognized names. A choice shaped by your home.

We work with Crystal Windows, Marvin Windows, Pella Windows, Andersen Windows, JELD-WEN, Aluprof, Alumil, Aluplast, Schüco, and Reynaers.

Ten names, two very different traditions. The American manufacturers build finished windows for North American openings and certify them to North American standards. The European houses design profile systems that a fabricator turns into a window — which is why they arrive with tilt-and-turn hardware, deeper frames and a different vocabulary.

The right one depends on the property, not the logo. Below is what each is genuinely best at, and each page goes further into where the differences show up.

North American manufacturers

Finished windows in vinyl, wood, clad-wood and fiberglass, certified to North American standards.

European system houses

Aluminum and uPVC profile systems, typically tilt-and-turn, fabricated to order.
