Aluminum Casement Windows Built for Philippine Storms

A casement window is hinged on the side and swings outward horizontally — giving 100% opening width for maximum airflow. An awning window is hinged at the top and swings outward at the bottom, creating a rain-deflecting overhang. Casements provide more airflow; awning windows can stay open in rain.

Yes, when properly specified. We use Series 79 premium profiles with 1.4mm to 1.6mm gauge aluminum, 4-bar stainless steel friction stays rated for wind load, and compression EPDM rubber gaskets for a full perimeter weather seal. Multi-point locking systems add an additional level of wind resistance.

If there is no exterior clearance for the sash to swing outward, we can specify an inward-opening casement instead. Inward-opening casements are common in commercial and high-rise applications. The trade-off is that the open sash occupies interior space and is more vulnerable to rain if left open.

A standard Series 38 casement window (600mm x 900mm) with 6mm tempered glass starts at approximately P3,500 to P5,500 installed. Series 79 premium profiles with thicker glass and multi-point locks are priced higher. We provide full itemized quotations based on exact dimensions and specifications.
