Dual Pane 3x2 windows?

[mltdwn12]

I'm working on insulating my 32x50 pole barn before winter gets here in Berkeley Springs, WV. I've heard the single pane horizontal sliding windows will be a source of heat loss and I should change them out with dual pane models. I have not been able to find any 2x3 units, any suggestions?

Home depot sells 24x36 replacement windows as do most stores that sell windows. If those won't work you can order custom sized windows.

Storm windows would be almost as effective, cheaper and easier to install

I second the storm window idea

They can be installed inside if it is easier

even the best of windows are a great heat loss.
what you have there is maybe R-1
a thermal pane is maybe R-5 at best
calculate the square footage of windows vs the square footage of heat loss, it doesn't add up to much of an issue,
however, as others noted, add storms, or plastic for the cheap way out .
if you're heating constantly , look at better windows . or not
my $0.02

Each pane of glass is just an R1 so single is R1, double is R2, triple is R3. You add argon, coatings etc to any of those and they only go up less than 1 in R value. So max double pane is R2.5.. Calculate heat loss and unless heated 24/7 you are never going to lose enough heat to pay for the windows.

Thanks for all of the replies, everything you all say makes sense given the size of the windows vs. the overall wall space. The other thing I was told is coming true, I was told I am building a work space not a living room. With temps in the high 40's and 50's lately, I get out there and continue working on the studs for insulation, I get warm and start peeling shirts off I really just need the main large space warm enough that the motors don't freeze, say 50-60 degrees and the smaller work space to be about 65 degrees for fiberglass work.

Small world. I live in Berkeley Springs also. I live up by Hancock, how about you? What are you going to do in your new building? How are you going to heat it? Heat Pump works well. For the size of your building you may need two.

I have 5 2x3 dual pane but they are vertical, not horizontal. 2 of the 5 have lost their counter weight springs, in spite of being fairly expensive units. Two of them really need to be 2x5, so I may be chopping into the wall in the future LOL.

Motors will not freeze until allowed to "cold soak" at below 30 degrees.
A cold soak at 30 degrees will take over 24 hours on a modern V6.
