Casement Door
The aluminum casement door uses a solid, precision-extruded frame and panel construction that provides structural rigidity and long-term dimensional stability under both thermal cycling and daily operational loading. Heavy-duty hinges and multi-point locking hardware ensure secure, rattle-free closure and reliable security performance across the door's full service life.
The perimeter sealing system uses continuous EPDM gaskets that maintain consistent compression contact around the full door aperture when closed, delivering effective sound attenuation, thermal insulation, and weatherproofing for both interior and exterior installations. Glazing options include clear, frosted, patterned, and laminated glass, enabling the level of visual transparency and privacy to be matched to the application.
Custom dimensions and panel configurations — single-leaf, double-leaf, and door-with-sidelight — are available to suit openings of any width and height. The casement door is a versatile, reliable solution for residential bedrooms, kitchens, balcony access points, and commercial spaces including offices, retail units, and hospitality environments.
