How to Insulate Windows for South Carolina Summers

Window insulation matters a great deal in South Carolina summers, because the heat load is high, the humidity is relentless, and the sun can turn a south-facing room into a heat trap by early afternoon.

You can often get meaningful relief with the right combination of sealing, shading, and glass upgrades, even before you start pricing new units.

Start With Air Leaks And Sun Control

Before you spend money on new products, check the simple failures that let hot air and moisture move through the window opening.

Run your hand around the edges of the frame on a windy day, or hold a thin tissue near the sash if you want a quick check for movement.

An experienced company can confirm the cause with a quick inspection.

Even a well-sealed window can dump a lot of heat into a room if the glass gets direct afternoon sun.

Closed blinds alone help, but tight-fitting cellular shades, lined drapery, or exterior solar screens do a better job of stopping heat before it reaches the glass.

Upgrade The Surface That Takes The Most Abuse

A quality film can cut glare and help reduce the hottest part of the solar load, though it will not perform like a well-made low-E unit.
