My detailed instructions are at http://www.northquabbinenergy.org then click on winserts at left side.
I give free winsert workshops around central Mass and we at NQE educate and advocate community groups to replicate this as possible.
For example a typical 5ftx3ft air tight double glazed R2 (ie U 0.5) window typically loses $45 (oil at $2/gal & 80% eff system) worth of heat per winter in New England. Winsert material cost would be about $12 , labor about 90mins each, thus paying back $20+ for each winter for that window.
You can work out your total window heat loss in Btus for a whole average winter with a little multiplication.
Btu loss = window U value * total window area * 24 hrs * HDD for your location.
HDD is heating degree days & look up nearest city to you here:- http://www.nrcc.cornell.edu/ccd/nrmhdd.html.
U value is 1/R value. A single glaze window has a U value of about 1.1 (ie R 0.9) and double glazed ranges in U value 0.5 - 0.4 (i.e. R 2 - 2.5) Lower U i.e higher R is better.
To convert the Btu cost to kWh of electric heat, divide the Btu s by 3,412.
To convert the Btu cost to gals of oil, divide Btu s by 139,000 then mult by about 1.25 for an 80% efficient system.
If you have really large windows and can sacrifice some winter day light, you can put 3/4" thick foil faced foam board or foil faced bubble wrap inside half the winsert. That would step up the winsert's R value improvement from almost +2 to about +3.5 and improve a R2.5 window to about R6.
If you have any air infiltration, use removable rope caulk to seal the windows tight before using winserts.
Good luck
