GR65 Narrow Framed Fiberglass Reinforced Polyurethane Casement Doors

The GR65 casement door is engineered with a Fiberglass Reinforced Polyurethane (FRPU) thermal break frame—stronger than aluminum and naturally resistant to heat and cold transfer. The 3-chamber profile design, combined with double Low-E glass and argon gas filling, achieves an outstanding U-value down to 1.1—delivering noticeable savings on your yearly energy bills. Premium German ROTO hardware and a full EPDM sealing system guarantee smooth, silent operation with zero drafts and excellent weatherproofing. The eco-friendly waterborne finish is UV-resistant and won't fade or yellow. For luxury villas, apartments, and hotels, the GR65 means less outside noise, stable indoor comfort, and significantly reduced utility costs—exactly what a premium door should deliver.
