Harvey works ok for New England..

Apparently a company called Serious Windows makes some... really serious windows as far as R-value.

They have double pane windows that between the two layers of glass they have layers of UV stabilized plastic that create a total of 4 air chambers in the glass so you get a window that has an R-value of up to R-11.1 for a fixed window, where a clear uncoated panes of glass with air in the cavity between the panes has an R-value of 2, adding argon bumps it up to R-3, for comparison R-11 is the insulation value of a 2x4 wall.

Most windows in the house never get opened, altho it is a good idea to have some windows that do open for cross venting but if you can make a number of the windows in your house picture windows (non opening) they will both cost less but they will insulate better.

There's a government program that tries to achieve economy of scale and is called "High Performance Windows Volume Purchase Program".

Link here.

Their objective is R-5 or better windows.

Here is a link to a map that may help you find financial assistance to get high performance windows.

Hope this helps.

Well those are pretty impressive I must say Ryland, I am doing my windows this spring in addition to renovating my existing walls with spray foam insulation.

Now comes the fun part, seeing how much these types of windows are going to set me back. Thanks again Ryland.

Please let us know when you get quotes. I also looked contacted Serious Window and they pointed me to a distributor who never contacted me back...

I am also interested in seeing those quotes. I'm interested in SeriousWindows, but if they're >$400/ea, it doesn't really matter if they're R1000.

I've got four 45"x45" sliding Anderson windows in my den. Nice double pane,
but they are a bit too leaky and just [B]Cold [/B during the winter time..

So, I'm thinking of adding a sliding storm-window over them, or replacing them,
or adding removable double pane plastic 'storms' inside.. Etc. etc.

But it seems we now need to replace the old curtains.
The cheapest insulated 'Cell' blinds are about $100 each! Dang!! :eek:

I have been in contact with a Serious window dealer here in Western MA and he told me that they tend to go for about 15% more than Pella.

And Xringer, FWIW I have some curtains the little lady picked up at Target or Wally World for about $15 each. They hang all the way to the floor and do a great job of insulating and keeping the sun out for when I watch a movie on the projector during the day. From there you can get foil faced bubble wrap type fabric/insulation for not too much $ at Joanne Fabric to sew to the inside. Might be worth looking into. I haven't done that yet but when the local Army surplus store went out of business several years ago we picked up about 20 of those green wool blankets and layer them with the curtains. Makes a HUGE difference.

A basic, 36"x66" double-pane Pella window goes for $225 at Lowe's. That would suggest $260 for SeriousWindows.

Hmm, R13 for $260, or R3 for $130? I'd have to do some math. What is the annual energy cost of a R3 window?
