The Attic Tent is a patented insulating approach designed to produce a barrier against the transfer of air and heat between the attic and rest of the home. Built out of fire retardant material, the Attic Tent blocks the exterior movement of heated air during winter and entrant of warm air during summer. It has been set up to moderate air and heat transfer in and out of the residence by as much as 71%. Result: lower heating and air conditioning costs respectively, sometimes by as much as 20%. Moreover, its solitary scheme prevents insulation particles from falling into the house when accessing the attic.

HeatBloc radiant heat barrier works by changing the emissivity of the surface where it is applied. Building products such as wood, brick, and plasterboard have high emissivities (0.7-0.95). When heated, they radiate most of their heat to cooler surfaces by allowing the heat to penetrate the roof into the attic and from the attic into the house. HeatBloc lowers their surface emissivity to under 0.23, lessening their ability to radiate heat and therefore letting less heat penetrate the roof into the attic.

HeatBloc does not lose its effectiveness over time like some products. Foils can tear and require the staples to penetrate the barrier. Foil chips can accumulate dust, which diminishes their effectiveness. HeatBloc will last as long as the surface area it is applied to is not damaged or disturbed and nothing is coming in contact with the product. HeatBloc allows water vapor to permeate, and does not trap water vapor within roof decks or sidewalls.
