IGMA Offers New Visual Quality Guidelines

September 8, 2009

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.
