The Attic Tent is a specially engineered, patented insulator designed to create an air-transfer barrier between your attic and living areas. It is a practical and economical solution to a problem that has existed since homes were first built with overhead attic entries; that problem is wasted energy through and around the attic door and stairs. Through the years, homeowners who have been aware of air transfer/loss through the attic have attempted to remedy it by placing insulation around the attic door opening. Unfortunately, this technique doesn't provide an air-tight barrier, therefore, little reduction in the amount of energy waste and air loss is achieved. It also creates harmful airborne particles of dust and fiberglass each time the attic door is opened or closed.
