The 18 x 36 casement window is a 457 x 914 mm aluminum opening unit featuring hand-crank operation. Matched to the DERCHI WY-72, WY-86, and WY-100 cranked-out window family, it suits compact residential and commercial openings.
6063-T5 aluminum frame with 72, 86, or 100 mm depth options
Double tempered glass with EPDM rubber strip sealing
Made-to-size production supporting project customization
The structure centers on a 6063-T5 aluminum profile with a 1.4 mm wall thickness per catalog reference. Buyers select from 72, 86, or 100 mm frame depths, paired with EPDM rubber strip sealing and double tempered glass configurations—5+27A+5 mm for WY-72/WY-100 and 5+15A+5 mm for WY-86.
Unlike standard push-out units, this cranked-out window uses a hand crank for controlled ventilation. The 457 x 914 mm nominal size fits compact openings in kitchens, bathrooms, and stairwells, while multiple glass and frame options allow thermal and acoustic tuning per project.
