Tamarack – Your source for quality ventilation, air sealing and pressure balancing products

Featured on Ask This Old House and the Today Show

Since 1993 Tamarack has been an industry leader manufacturing and distributing innovative and energy efficient ventilation and air sealing products that improve indoor air quality with a focus on health, safety, and sustainability. Our mission is simple: offer high quality products and back them up with technical support and customer service.

We are driven by the desire to improve residential indoor air quality. Our first signature product was the HV Whole House Fan, a product category in which we continue to lead. Unique to the industry, this product features insulated doors that seal when the fan is not in use. A variety of sizes and configurations are available for virtually any cooling or air exchange need.

Our Perfect Balance and Return Air Pathways solve the challenges associated with HVAC systems that do not evenly distribute conditioned air throughout the home. Most often used in bathrooms, The Perfect Balance is a great product to make sure the bath fan can move air out which in turn will help reduce mold build up.

Our popular Cape Backdraft Damper – a simple and brilliant design – eliminates the possibility that outdoor air will flow back in through a fan when not in use. And it accomplishes this without diminishing the fan’s ability to move air out.

In 2020, Tamarack completed the purchase of Battic Door – an innovative company that makes products that help on the air sealing side of the equation.

The E-Z Hatch is a fully assembled attic scuttle insulated to R-50 with an R-80 option. Triple gasketed with finished trim – ready to install.

The Battic Door is a retrofit system that improves the performance of a pull-down stair assembly. Another easy to install effective solution to help seal your attic.

And the Fireplace Plug is used to seal the chimney in a home when not in use – stopping both incoming and outgoing air through one of the largest holes in most homes.

As a distributor, we offer the full line of Delta Breez Fans. Delta fans are Energy Star Most Efficient, ASHRAE 62.2 compliant and easy to install. Tamarack also offers a Mainstream Fan specifically for mobile home applications.

We offer these and other innovative products that help our customers achieve ASHRAE standards., Energy Star certification, Build Green and LEEDS accreditation with our cutting-edge designs.
