Single Hung Casement Window Features
Our single hung casement windows combine emergency egress compliance with casement-style ventilation, engineered for basement safety and enhanced airflow control. Featuring a dual-action design (vertical sliding + outward swing) and 0.5″ laminated safety glass, these units deliver:
Code-compliant escape – 20″×36″ clear opening meets IRC 2025 egress requirements
Hybrid operation – Slide bottom sash vertically or swing outward 90° for full ventilation
Energy efficiency – Triple weatherstripping achieves U-factor 0.29 (exceeds ENERGY STAR® by 19%)
Technical innovations include:
Tilt-clean mechanism – Remove bottom sash in 15 seconds for interior/exterior glass maintenance
Impact-resistant frames – 2.8mm reinforced vinyl withstands 180 PSF wind loads (ASTM E330)
UV-blocking glass – Low-E coating reduces solar heat gain by 68% (SHGC 0.18)
