Insulated Replacement Windows

How Well Insulated Are Replacement Windows?

Windows and doors account for 50% of your homes heat loss! Buying new windows can be a challenge if you don’t know how to tell them apart. Windows are measured in their center and assigned a “R-Value”. A single pane (piece of glass) has a R-Value of 1 and a simple double pane window has a R-Value of 2. When you add a layer of Low E glass the rating jumps to 2.8 and if you add Argon gas the number jumps to a 3.6. A triple pane window with Argon gas brings the number up to 4.3. A window with E-Max glass tops the ratings with a R-Value of 9!

Can you image how much warmer your home would feel with replacement windows that insulate as well as your walls? Changing your windows from single pane to the triple pane E-Max windows can cut your heating bill by as much as 30% or more. In the MA & RI area FHI Windows is the only window company that sells the E-Max windows. If you live in another area you can contact FHI Windows and they will put you in contact with a local dealer.
