The Belmont Spacer Performance

Duralite® spacers are the best spacers in comparison testing with other commonly used insulated glass systems. Duralite® spacers yield a lower window U-value, up to 0.03 over other less efficient systems. And that means more comfort and energy savings for you.

Condensation Resistance: No spacer system can eliminate condensation, but Duralite® reduces conductivity by 50% over other warm edge spacers. Reducing conductivity also reduces condensation.
