You're already paying for new windows, whether you install them or not. According to the US Department of Housing and Urban Development, 70% of a home's energy loss is though windows and doors. Summer heat gain and winter heat loss contribute to thousands of dollars of wasted money for millions of Americans.

In addition to heat loss and gain through glass, gaps around windows contribute to the problem as well. Even a gap as small as 1/16th of an inch all the way around is equivalent to an opening the size of a brick. No wonder your fuel and electric bills are so high.

NESCOR's Heat Shield 19 window is one of the best on the market today. It far exceeds the US Energy Department's minimum efficiency requirements. In fact, when the government started awarding Energy Star ratings back in the mid 90s, NESCOR was among the first 18 companies nationally to be awarded this distinction for its products.

Heat Shield 19 vinyl replacement windows are the only product that control all aspects of glazing performance: visible transmittance, shading coefficient and R-value, as much as 74% higher than popular types of low e glass sold in many windows. The key is a thin layer of Heat Mirror film suspended between two panes of glass. This helps keep heat indoors in the winter and outside in the summer.

In addition to the aesthetic and economic benefits, our vinyl replacement windows also protect your home's contents from fading, they enhance security and also deaden outside sound. We have many styles of grid patterns and interior colors available to suit your decor as well.
