Rubber strip has been used in recent years, EPDM, which can ensure better elasticity and anti-aging performance, but the glass groove rainwater with rubber strip will still leak into it, so we need to milling drainage holes and slots.

The water tightness of aluminum window is related to the strength of aluminum alloy door and window members, rubber strip section and material, drainage system, window structure design, etc.

This glass window suit for home and office,made by thermal-break aluminium profiles of very good heat insulation and energy saving performance.
