Everything You Need To Know About Energy Efficient Insulated Replacement Windows

Did you know that you can reduce your energy bills by as much as 15% when you replace your old windows with Energy Star qualified insulated replacement windows? You are also eligible to claim tax credits. These energy efficient replacement windows have the following special features.

Less Conduction

Heat conducts easily through single pane glasses, metal pacers, and frames. This conduction can only be impeded when the pathway is interrupted with a material having low conduction properties. Unlike normal windows, energy efficient windows have multiple panes of glass. The space between these panes is filled with a low conductance gas like krypton or argon. The window panes and the spacers are also thermally resistant.

Air Leakage

An average home loses about half of its cooling and heating energy to the outdoors, through air leakage. This leakage takes place through the windows. Energy efficient replacement windows come with durable weather stripping and quality closing devices. These tight seals increase comfort and reduce energy bills.

Selective Transmission of Heat

When energy from the sun hits a window, ultraviolet radiation, heat, as well as light are either absorbed, transmitted through, or reflected back. Energy efficient windows let in the proper mix of light and heat in any given climate.

These windows are double glazed and come with low-E (low emissivity) glass coating that provides thermal protection. In combination with low conductance gas, low-E coatings improve the energy efficiency of windows by close to 100% as compared to clear glass. It also reduces cold climate condensation and diminishes fabric fading. The visible transmission in energy efficient windows is also high, so you can see through them easily.

Quality Replacement Window Installation

If an energy efficient window is to perform its best, it should be correctly installed. When these replacement windows are properly installed, water damage and air infiltration are prevented. Tenco Construction can professionally install your new replacement windows correctly and at a low cost. Call Tenco Construction today at (866) 272-1451  for a free no obligation estimate.
