Making your home more energy efficient reduces your impact on the environment. One of the biggest steps in converting you home to a Green Home is replacing your old windows and doors. M&I Windows is dedicated to supporting Green Home trends. Large amounts of energy are lost through old window glass and frames. Single pane glass and aluminum/wood frames allow virtually unrestricted flow of heat and cold making it almost impossible to maintain consistent temperatures in the home. Not only does M&I Windows offer free estimates but we will also advise you on what window and glass options are best for every room situation in your home. M&I Windows takes the environment seriously setting us apart from the competition. We take it so seriously that we will even give you a $250.00 credit toward upgraded glass options above already standard Low-E and argon gas. Call M&I today for more details.
