R-value and Air Exchange in Hangars

An R-14 door that leaks air is effectively an R-0 door. That reality is often overlooked in hangar design.

Hangar efficiency is driven by air exchange, thermal bridging, and how quickly a space can recover after a door cycle. Steel hangar doors rely on segmented panels, metal frames, and hardware. Air infiltration and metal-to-metal contact allow conditioned air to escape and outside temperatures to enter, regardless of the foam rating printed on the door.

Instead of only looking at R-value, consider the time and energy required to maintain and bring the hangar back to set temperature.

Para-Port® Doors are engineered to minimize those losses. A continuous, non-conductive curtain eliminates thermal bridging, while high-integrity compression seals reduce air infiltration. Just as important, the door operates in a way that limits air exchange during opening and closing, moving efficiently without the prolonged exposure common with other hangar door systems.

The result is faster temperature recovery, reduced HVAC load, and lower operating costs. By focusing on effective, whole-door performance, not just nominal R-values, Para-Port® Doors help facilities maintain stable interior conditions with less energy and less recovery time after every cycle.
