The fabric used to make the product provides a high r-value of 7.6 which controls heat loss due to radiation, conduction and infiltration. However the four-layer fabric is only half of the story. Equally, if not more important, is the way in which the Energy Cinch is held inside the window casing. An open-ended 'pocket' is sewn along each end of the fabric. A tension rod is then inserted into each pocket. One rod is placed at the top of the window casing and one at the bottom. The fabric is held taut in the window casing covering all of the glass. This method of installation actually stops the 'convective loop' which is a major source of heat loss. The convective loop occurs when heated air rises and is attracted to the cold glass of a window. The warm air hits up against the cold glass, cools, and drops to the floor and now must be reheated again only to go through the same 'loop' cycle. So, essentially, you are payng to re-heat air over and over again. The Energy Cinch stops this cycle by not allowing warm air to get to the window glass ( due to the insallation method) and reflecting the warm air back into the room ( with the high r-value fabric.) Using the four-layer fabric in a traditional curtain or drape configuration will not produce the same results as the Energy Cinch. Warm air will easily find its way around a drape or a curtain and the convective loop will thrive. The Energy Cinch is offered in made to order sizes at www.energycinch.com Thanks for your time.
