Energy efficiency is one of the top reasons Raleigh homeowners decide to replace their windows. Old single-pane or poorly sealed windows allow heat to pass through the glass and around the frame, forcing your HVAC system to work harder year-round. Modern energy-efficient windows use double or triple pane glass with low-emissivity coatings that reflect heat rather than absorbing it. In summer this keeps the sun's heat outside. In winter it keeps your heated air inside where it belongs. Harland Windows and Siding carries window products rated for the North Carolina climate, including options with R-10 ratings which represent the highest performance available for residential windows.
