Advantages of Casement Window
Excellent ventilation performance
Casement windows can open fully to 90° or more, allowing for smoother indoor airflow and improving ventilation efficiency by 30%–50% compared to sliding windows. They are ideal for kitchens, bedrooms, and living rooms where rapid ventilation is crucial.
Strong sealing and protection performance
High-quality casement windows feature multi-chamber aluminum alloy or PVC frames and EPDM sealing strips, forming a wraparound, tight seal when closed. This provides wind, rain, and dust protection, while also reducing noise by 25–35 dB.
High safety
Equipped with multi-point locks, tempered or laminated glass, the window sashes offer limited opening and strong impact resistance. The anti-pry design effectively prevents forced entry, making them suitable for ground-floor residences, villas, and schools.
Energy Efficiency
Using Low-E glass and double or triple-glazed structures reduces heat transfer, providing insulation in winter and heat insulation in summer, reducing air conditioning and heating energy consumption by 15%–30% and improving living comfort.
Easy Washing
Case windows can rotate 180° or 360° (depending on hardware design), allowing for easy cleaning both inside and out. No need to go outside to clean; inward-opening safety supports can be used in high-rise buildings.
