Prevent hot air from entering the attic while the inlet closes with an Attic Airlock. The airlock is installed above each of the ceiling inlets to eliminate heat loss while the inlets close. It creates an air chamber between the room and the attic, reducing condensation in the attic and increasing the life of the building.

The Attic Airlock will pay for itself in a reasonable amount of time with fuel savings, even heat and better-producing pigs.
