High Performance Windows

Quality, energy efficient windows are an important part of a high performance green building.  Special coatings and gas fillers placed between two or more layers of glass can dramatically improve the energy efficiency and comfort of your home.    Designing a new home or addition? This is the ideal time to select the highest rated windows your budget can afford.   While cutting corners on window costs up front can lower the first cost of your project, money invested now in high performance windows will eventually be returned in the form of reduced energy usage and increased comfort. 

 However, the considerations for replacing functioning windows are different.  Unless an existing window is being replaced due to damage or for aesthetic reasons, it is far more cost effective to seal any air leaks in the surrounding window frames and to install tight fitting interior storm windows.   Money saved by not purchasing new windows can then be applied toward other more cost effective energy upgrades.
