EASTERN TIGHT

The Eastern Advantage

Using EASTERN TIGHT™ fittings will reduce installation time by eliminating the need to seal joints in duct systems - no sealer, no mess, and no added costs. Instead, duct arrives at the job site with factory mounted rubber gaskets that provide a reliable, airtight seal.

• Eliminates costly sealer and leakage points
• SMACNA Class 3 Leakage standards for -2” w.g. to 10” w.g.
• Withstands temperatures -20 ℉ to 212 ℉
• Smoke-developed and flame spread ratings 0/0 per ASTM E84
• Secure with #10 TEK screws per SMACNA standards

EASTERN FLANGE

The Eastern Advantage To save contractors valuable field installation time, the Eastern Flange is pre-assembled to spiral duct at the factory. Spot welds and any necessary sealing is already completed before it arrives at the jobsite. A tight fit is esssential to preventing leaks in duct. The Eastern Flange makes connecting duct systems quick.

• SMACNA Class 3 Leakage standards for -2” w.g. to 10” w.g.
• Withstands temperatures -20℉ to 212℉
• Smoke-developed and flame spread ratings 0/0 per ASTM E84
• Secure with self-tapping screws per SMACNA standards

E-FREE

Good acoustics and good thermal performance are required in the modern built environment. Dual wall round and oval duct with interstitial fiberglass insulation has been the gold standard for providing both at a reasonable price. In the past few years there has been concerns raised about the presence of fiberglass in the airstream creating a health hazard. This has lead to the emergence of specifications calling for a mylar barrier between the fiberglass and the perforated inner duct wall, which seriously degrades the acoustical properties of the fiberglass,or calling for the use of an elastomeric as the insulation medium, which is heavy and extremely expensive. We introduced on 2013 our E-Free insulation. E-Free has a sound transparent polyester rayon facing between the fiberglass and the perforated inner wall, keeping fiberglass out of the airstream. Best of all it is competitively priced with the use of standard matt faced duct liner.
