Tamarack RAP Interior Wall Vents

Most bedrooms do have any air return to the furnace or air conditioner. The resulting build up of air pressure means that the HVAC system is working harder than it should. Undercutting the bedroom door provides too small an air pathway. A better idea, install the RAP in the bedroom wall. A honey comb baffle in the Tamarack RAP smoothes the flow of air while greatly blocking out light and sound from the adjacent room or hallway. Also great for darkrooms!! Comes in white, but can be spray painted.
