If the installed site for your windows and doors is more than 1,200 feet higher or lower than your IG production location, you risk a visible bow or bulge or even breakage. Your Energy Star rating can also suffer. Using a breathing tube means you cannot offer the benefits of argon or krypton.
Pressure balancing at production: no onsite adjustment needed
The HELANTEC ISO Altimeter Professional solves these issues accurately and quickly at installation without any further adjustment required. German engineered and proven in years of use, the Elevation Adjustor balances IG for final elevation using any mix of air, argon or krypton gas.
