    installing double glazed windows to insulate a room

    Window Specialists

    How well do double glazed windows insulate a room? Are they enough to significantly improve the insulation of a room or will I need to have more done? I am considering having double glazed windows installed either way but I’d like to know how helpful they can be when it comes to home insulation.

    "Hi if you install C-RATED GLASS in your new frames they have LOW-E coated glass and come with ARGON GAS the heat retention is about 50%, however if you use A-RATED glass which is all we install you get LOW-E GLASS, ARGON FILLED UNITS, WARM EDGE SPACER BAR and LOW IRON GLASS and heat retention increases to about 89%. I hope this helps."
