Product Details
The 30 x 42 casement window is built on a 6063-T5 aluminum profile with a 1.4 mm thickness, paired with EPDM rubber strip sealing to manage air and water infiltration. Buyers can select from three frame depths—72 mm, 86 mm, or 100 mm—allowing the aluminum casement window 762 x 1067 mm to match specific thermal and wind-load requirements. The WY-72 and WY-100 series use double tempered glass (5+27A+5 mm), while the WY-86 series features 5+15A+5 mm glass.
Unlike standard push-out frames, the hand-crank casement window mechanism allows users to regulate airflow without reaching over sinks or furniture, making it suitable for kitchens, bathrooms, and bedrooms. The WY-72 WY-86 WY-100 aluminum window family addresses space constraints while providing secure ventilation through multi-point or single-point locking systems, depending on the selected series.
