Transfer Grilles/RAP

The Tamarack Technologies Return Air Pathway (R.A.P.)/Transfer Grilles, wall mounted or door mounted, provide your home with proper air flow which promotes healthy indoor air quality, relieves hot and cold spots, and can reduce the strain on your A/C system while improving its energy efficiency. This allows homeowners to save on both cooling and heating costs.The Perfect Balance® In-door Return Air Pathway (R.A.P.) /Transfer Grille installed in the bathroom door helps prevent mold and mildew by providing the bath fan with much needed makeup air.

A door undercut does not allow for sufficient airflow. This restricted air flow will cause air pressure imbalances to build up in bedrooms and bathrooms. The patented baffle material in the Tamarack RAP/Grilles helps to mitigate sound and light transmission for privacy, an added bonus that door undercuts and empty transfer grilles do not provide. Solve your ventilation needs with a Tamarack Return Air Pathway. Don’t just take our word for it see what the experts at Fine Homebuilding like Mike Guertin have to say! Tamarack R.A.P. products are BPI listed. Return Air Pathway/Transfer Grilles are perfect for bathrooms, bedrooms, closets, and home offices.
