In replacement windows, spacer is located in between panes of glass. Spacer is one of the crucial elements in the window construction. Yet, it is often overlooked by the homeowners in CT. Many window manufacturers still use metal spacer in the process of production of vinyl windows. And metal causes excessive condensation and heat loss. Good, non-metal spacer creates an excellent thermal barrier. Similarly, it reduces the heat and cold transfer into your home. This gives you much greater comfort of living during summer and winter months. It is a good idea to keep this in mind when choosing the right window product for your home in Connecticut since our state receives only about 10-15% less sunshine than Florida.
