ASTM E90-90 Sound transmission loss test
Sound transmission class was determined to be STC 27
A further test was done by hermetically sealing around the edges with “Dux-Seal” which only raised it to STC 28, showing that our seals are extremely good. This test qualified us to supply windows to the Boston Central Artery Project for soundproofing around their construction sites.
