In extremely cold climates, the window frame material you choose is important. It should provide excellent insulating qualities – in other words, it should keep the cold outside where it belongs.
Best Insulating Frames
Wood is an outstanding insulator? in fact it insulates 1,800 times better than aluminum. (When you were a child, ever remember sitting next to those old-fashioned aluminum school windows? Brrr.)
Fiberglass composite windows and doors are also an excellent choice, they offer the insulating quality of wood and won’t turn brittle or shatter in extreme cold.
Vinyl windows and patio doors feature insulating air chambers inside their frames to increase insulating performance.
Best Insulating Glass
Windows and doors with double or triple-panes Low-E insulating glass with argon (or another insulating gas) in between the panes will maximize the comfort and energy efficiency of your home when the temperature plunges. Pella windows and doors with Low-E triple-pane glass are top rated for energy efficiency among the best national brands.
