Well-constructed windows and doors reduce the transfer of heat or cold between the interior of your house and the outdoors. This means more consistent indoor temperatures, fewer drafts and less strain on your HVAC system. That adds up to reduced energy consumption that can save you 7-24% off your energy bill.
