ZS-2750 BlastMax®

The 2750 is designed to accommodate the desire for fresh air ventilation without the sightline of a conventional inserted aluminum window, allowing the end user all of the benefits of a commercial window without compromising the aesthetics of the building. The window is specifically designed to be inserted into storefront and curtain wall framing. It has been tested to meet the demanding standards of ASTM, GSA and DoD.
