Energy Efficiency

Double hung windows allow large amounts of sunlight into the house while keeping out the cold or heat. Energy Star certification means your windows will help reduce the amount of energy you consume and bring down the cost of your overall energy bills. All the windows sold by Comfort Windows & Doors are manufactured in Canada, which reduces the cost of transport while supporting home-grown businesses.

Air Conditioners and Other Additions

Most in-window air conditioners are specifically built for double hung windows. The air conditioning unit is balanced on the window sill of the open window and the bottom sash is pulled down flush to the top of the air conditioner and affixed to hold it in place. Double hung windows also allow for easy installation of insect repellent window screens.
