A video tour of the Ideal Pet Ruff-Weather All-Weather Energy Efficient Pet Door. www.idealpetproducts.com Whether you live and work in the Great Plains or north where the temperature plummets, or in the south-east or west where summer is endless and the cost of energy has sky rocketed so either heating or cooling the back yard with an old fashioned pet door just won't do anymore. In some cases the energy waste is like opening and closing the door itself 4 or 5 times a day. Ideal Pet has the answer with The Ruff-Weather Door's air pocket between 2 soft flaps, making it a great energy efficient insulator. The Ruff-Weather series (in Small, Medium, Extra Large and Super Large) are designed to give an air pocket of up to 3 inches between the 2 flaps in a door installation; with the available wall tunnel kit, an air pocket of up to 9 inches. This is serious energy efficiency. Features Include: * Energy efficient structural foam molded plastic. * Adjustable frame telescopes 3/4" to 1 3/4" thickness. * Nylon for draft restrictor. * Innovative Double Vinyl Flap design creates energy efficient air pocket for maximum insulation. * Optional Wall Kit, sold separately. www.idealpetproducts.com
