Patent attributes
An inexpensive, lightweight, reusable and detachable or removable insulation device for residential and commercial dwellings and similar heated structures. The device has an inner-portion insulating pad adapted to fit inside of a typical entrance or window unit framing. The device further has an outer-portion insulating pad adapted to overlap the window or entrance framing. The outer-portion insulating pad is provided fasteners so as to be secured to the building wall structure outside of the framing and surrounding the window or entrance framing by. During cold weather months, the present invention will greatly restrict warm air from escaping between small crevices in inept window systems by fitting firmly into window framing using a insulating material, thus creating a thermal barrier and improving the efficiency of the furnace by reducing the demand for electricity or fuel consumption.
