The superior performance of Sheffield® windows starts with innovation. Every precision-engineered component contributes to superior energy savings. The multi-chamber design helps trap dead air to produce an effective insulating barrier, while extra-thick, fusion-welded frames and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration, adding up to greater energy savings – and lower utility bills.
Windows and doors are typically responsible for about 40 percent of your home's heating bill. Thermal windows are typically two to four times more efficient than older single pane windows. That means you can expect your winter heating bills to drop on average about 20 percent to 30 percent. The bigger your fuel bills and the draftier your old windows, the quicker your new windows will pay for themselves.
