About Our NJ Replacement Windows

AGM Windows and Siding  is a replacement window contractor serving New Jersey and cover all of Northen New Jersey and Central New Jersey. We offer sales and installations of some of the most energy efficient windows available including Okna Windows, HiMark Windows , and Elite Windows by Affinity.

An average home can lose over 40% of its heat or air conditioning through inefficient windows.

 Energy Efficient Windows  bring savings and comfort.

Quality matters

Windows are a serious investment and choosing the right product is of the utmost importance. Be sure to choose a premium grade vinyl window. Lower cost vinyl windows are simply not strong and over time can become soft, brittle and warp. This will compromise the structural integrity of the window; eventually causing air leaks which lead to thermal failure, glass fogging, and difficulty operating the window. AGM offers Okna Windows which are engineered using a high-grade uPVC and will maintain their efficiency and beauty for years. We carry each Okna Window line. 

Choose a window with a low U-factor.

The U-factor is a rating determined by the Department of Energy and given to a window based on how much heat loss it allows.

A low U-factor means less heat will escape during the winter and less air conditioning will escape during the summer.  A double pane window should have a U-factor of .28 or lower. Be sure that the "Full Window U-factor" is displayed and not the "center of glass U-factor". Full Window U-factor is the true measure of energy efficiency by the Department of Energy.

Each of our Okna Windows, HiMark, and Elite Windows exceed The Department of Energy U-factor standards for energy efficiency and  proudly carry the much coveted Enviro-sealed label. This means our environmentally friendly window systems reduce energy consumption, save homeowners from high energy costs and reduces harmful CO2 emissions to produce a greener future.

All of our windows come standard with energy efficient glass packages and are available in double or triple pane.
