Raleigh summers are hot and humid. Managing heat gain through windows is one of the most effective ways to keep your home comfortable and reduce air conditioning costs during the long cooling season. South and west-facing windows receive the most direct sun in the afternoon hours when outdoor temperatures are highest. These windows have the greatest impact on interior heat gain and are the priority when upgrading for energy efficiency. Low-E glass coatings are the primary technology for managing solar heat gain. Low-E stands for low-emissivity, referring to a metallic coating on the glass surface that reflects infrared radiation. Summer low-E glass reflects the sun's heat outward before it enters the room.

Solar heat gain coefficient, or SHGC, is the technical measure of how https://angelogjiu846.iamarrows.com/window-grilles-raleigh-styles-and-options much solar radiation passes through a window. Lower SHGC values mean less heat entering the home. For Raleigh's cooling-dominated climate, selecting windows with lower SHGC values for south and west exposures makes a meaningful difference to comfort and energy bills. Argon gas fill between the panes of insulated glass improves the window's overall thermal resistance. Argon conducts heat less readily than air, reducing the amount of heat transferred through the insulated glass unit. Harland Windows and Siding can help you select the right glass package for each window location in your home based on orientation and your priorities. Call 919-851-0060 for a free consultation.
