IGMA Offers New Visual Quality Guidelines

The Insulating Glass Manufacturers Alliance recently released its new TM-3100-09 Voluntary Guidelines for the Identification of Visual Obstructions in the Air Space of Insulating Glass Units.  Designed to assist in achieving the long-term performance of IG units, the advisory guidelines are intended for use by those who design, specify, manufacture and install insulating glass.

More information about the document, developed by the IGMA visual qualify working group, is available  from the IGMA Web site.
