GR70 Fiberglass Reinforced Polyurethane Casement Windows

The GR70 casement window is built for real-world performance. Its FRPU frame is stronger than aluminum and won't transfer heat or cold. The double-pane glass, argon gas, and Low-E coating bring the U-value down to 1.0—meaning lower energy bills year-round. German ROTO hardware and triple EPDM seals ensure zero drafts, smooth operation, and excellent soundproofing. The waterborne finish is eco-friendly, UV-resistant, and won't yellow over time. For luxury homes and hotels, it means less noise, stable indoor temperatures, and significantly lower utility costs—just what you expect from a high-end window.
