AirClip Muntin Key

The AirClip muntin key program is designed for easy installation of muntin grids to all warm-edge foam spacer systems–including  Glasslam’s line of Air-Tight spacer products and Edgetech’s SuperSpacer brand products. The molded plastic clips accommodate virtually any required airspace or application, providing a metal-free component for a true warm-edge muntin bar or Georgian bar unit, the supplier reports. The clip’s design allows efficient use with manual and automated IG unit production lines. Non-metal construction makes the clip about 700 times less conductive than aluminum clips, it is also noted.
