We have a very old home that started as a one room cabin in 1935 in the mountains of CA It has been added on to numerous times and the former owner changes out all of the windows to duel pane except one funky non opening window in a bedroom. Very cold in the winter. We needed a good solution. Found this company, and we are delighted with our purchase. Fits perfectly and is sturdy. Thank you for solving our problem!
