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 Energy Saver
Ultimatetm 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.
