Pull-down attic stair cases offer the wonderful convenience of being able to use overhead space for storage. However, the “hole” that is created in your home’s insulation to allow this access comes with a large price tag, in terms of heating and cooling costs. In the winter, the stairs offer little in the way of insulation to retain home heat, and let cold drafts into your living space. In the summer, home cooling money is lost as heated attic air pours into your living space.
The Therma-Dome® "Legacy" Pull-Down Attic Stair Cover by Yankee Insulation Products™ was first developed in 1991, and it remains the only pull-down attic stair case insulating product on the market that also provides an effective and durable air seal. To ensure a complete air seal, the continuous Q-Lon® gasket* works in conjunction with VELCRO®† straps. The exposed-use foil-faced polyisocyanurate foam insulation achieves an effective insulation value of R-13 (or potentially R-40 or greater, if used with the Maximize-R™ accessory). The Therma-Dome cover is lightweight, and easily moved aside for completely unobstructed access to the attic area.
The Therma-Dome Pull-Down Attic Stair Cover is designed to air seal and insulate your attic access opening, blocking the escape of home heating dollars in the winter and providing greater comfort and reduced cooling costs during the summer.
Constructed of exposed-use polyisocyanurate foam insulation board that is sandwiched between layers of laminated foil, this Therma-Dome product is designed to last as long as your home. The Q-Lon®* cellular foam core gasket (see photo of cross-section) provides a continuous air seal and stops costly energy drain.
Therma-Dome covers have been specified and used in many state, community, and utility energy conservation programs nationwide. These codes require the components of the cover assembly to be joined together with construction glue and the seams sealed with foil tape. The Therma-Dome kit is the only stair cover available that includes both the adhesive and the tape.
The use of a Therma-Dome cover can help conserve enough energy to pay for itself in just one year. (Energy cost savings may vary, depending on utility rates in your area.) The Therma-Dome cover is constructed of fire-rated material, meeting the most stringent state and local building code requirements.
The Therma-Dome "Legacy" Attic Stair Cover comes in an easily assembled kit, which includes six lap joint components, a tube of adhesive, foil tape, and step-by-step instructions. Equipped with only a caulking gun, scissors and a hammer, you can assemble and install this money saving stair cover in as little as fifteen minutes.
