German Engineering · Made for Qatar’s Climate
Premium UPVC and aluminium systems, precision-installed across Qatar since 2010 — trusted on over 5,000 projects in Doha, Lusail, Al Wakra, and beyond.
Why GQ
Over 15 years supplying premium UPVC and aluminium systems to Qatar, we've learned exactly what this climate does to ordinary materials — and engineered around it.
Two panes with an insulating air gap keep interiors cooler in summer and warmer in winter, cutting the load on your AC — in both our UPVC and aluminium systems.
The same air gap that blocks heat blocks noise — a real difference on a busy road or near the airport corridor.
Less heat transfer means lower cooling costs year-round — an investment that pays for itself over Doha's long summers.
Our UPVC and aluminium frames resist Qatar's heat without warping, corroding, or fading. No repainting, no rust — just a quick wipe-down.

German engineering, made in Germany
Our UPVC profiles are produced in Germany and paired with premium Turkish hardware, while our aluminium range is manufactured right here in Qatar under the Qalex brand — giving you a system built specifically for this climate, not adapted to it.
