Federal Tax Credits - Storm Windows and Doors

Storm Windows and Doors A less expensive approach to replacing old windows/doors, is to use storm windows to improve energy efficiency. When installed in combination with older, less efficient window/door, storm windows/doors can enhance efficiency by creating another barrier between the interior of you home and the weather outside. Tax Credit: 30% of cost up to $1,500 Expires: December 31, 2010 Details: Must be an existing home and your principal residence. New construction and rentals do not qualify.

• IECC 2009 - Standards published by the International Code Council, the IECC sets forth compliance methods for energy-efficient construction of both residential and nonresidential construction.
• SHGC (Solar Heat Gain Coefficient) - measures how well a window blocks heat from sunlight. The lower the SHGC, the lower the heat gain through a window. SHGC ranges from 0 to 1.
