Picking Windows for the Mount Pleasant Climate
In a warm climate, windows let in more heat than they lose. A low-SHGC Low-E coat keeps rooms cooler and trims the cooling bill; argon matters less than the coating here.
Climate regions run from 1 (cool) to 5 (hot); South Carolina sits in region 4.
Hurricane exposure is the first question for coastal South Carolina homes. Impact windows use laminated glass that stays in the frame when struck; they cost well above the standard units we price here, and some insurers lower premiums when every opening is protected.
Moisture is the quiet enemy of window frames in a humid climate. Insist on a sloped sill pan or flashing below each unit, so water that gets past the frame drains out instead of into the wall.
Strong sun fades floors and furniture as well as heating rooms. The Low-E coating in our base price blocks most ultraviolet light; dropping to clear glass would save only about $270 across 10 windows.
Plan to finish before hurricane season. Impact-rated units can take longer to build, and installer calendars fill fast once storms are in the forecast. As one of the more southerly cities in our South Carolina list, Mount Pleasant gets milder winters, so most of the comfort gain from new windows here shows up in summer. Window prices for Mount Pleasant (Charleston County) are worked out apart from those of Charleston, the nearest listed city, about 8 miles west.
