Operating Window Systems

Only Weck combines ventilation, beauty, and security - plus ease of installation - in custom pre-built operating glass block windows. Now kitchens and baths can have the luxury of real glass block windows that open and close at the turn of a handle. Fully operational venting windows are available in popular awning and casement styles. Both designs are equipped with durable hinged hardware and smooth operating handles.
BlokUp aluminum framework between blocks eliminates heavy mortar, lets in more light than conventional glass block windows. Two-Inch-Thin block, BlokUp and silicone sealant combine to take out more than one-third of the weight for easy installation and years of operating ease.

Security and Safe-Escape Features Operating glass block windows offer improved security vs. standard flat glass panels. Casement windows may provide a secondary avenue of escape or rescue in an emergency, such as a fire. Two-Inch-Thin Block Casement Windows, constructed with a minimum of three blocks wide and four blocks high, meet typical egress requirements. Check all applicable codes for specific requirements.

Weck Two-Inch-Thin Glass Block is available in 4 patterns.
