Test Results

Air Infiltration

Tested by the Vermont Energy Investment Corporation for This Old House.

November 1995 Salem Project

ASTM E 283-83   Air infiltration with 25 mph wind pressure.

Measured: .07 cfm /ft.         Test standard: .50 cfm/ft.

7 times tighter than the test standard!

Tighter than almost any replacement window costing 3 times as much!

Noise Reduction

Tested by Intertek Testing Services June 1997

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.
