qir IHome You Live In CHAMBERLIN WEATHER STRIPS .I . Stop the Drafts that waste yourFuel Not only are Chamberlin Weather Strips an insignificant investment when compared to the cost of your home-but a comfort investment that is returned to you many times over in the fuel that you save. This is easy to understand when you stop to realize that windows and doors are by far a building's weakest points. Q Around each unweatherstripped window is a crack equivalent to a hole the size of a brick -a clearance that must be there to permit them to open and close. Here you have a con stant source of air inleakage, causing from one to two complete air changes per hour and a temperature that is uncomfortable and difficult to regulate. Under such conditions you burn from 20% to 40% more fuel than is necessary. QClChamberlin Weather Strips will remedy this condition. It is obvious that it is false economy to choose anything less than the best weatherstripping money can buy-and for a possible slight difference in price, you cannot afford to be without Chamberlin protection.
