High temperatures, humidity, strong winds, and hurricanes can really take a toll on homes in the South. You can protect your home against the extreme elements by adding storm windows.
Less expensive than complete window replacements, storm windows add a layer of protection to your home and help increase your comfort. If you're adding or updating storm windows, here are some things to consider:
Intense sun rays: Look for storm windows that feature low-emissivity (low-e) glass coatings. These panes have been treated to reduce the sun's radiation. Your home will be more comfortable and your furniture and indoor surfaces will fade less.
Heat transfer: Storm windows have been shown to lessen air movement between the window units. When you slow the rate of heat transfer, you may find you spend less cooling your home. Look for storm windows with a low U-factor, which means the panes will better resist heat flow.
Condensation: When humid exterior air meets a surface cooled by air conditioning (your window), condensation forms on the inside of the pane. Not only does condensation block your view, the moisture can damage sills, walls, and furniture. Because storm windows trap air between the window units, they lessen the effects of condensation and keep residual drips away from your interior surfaces.
High winds: Strong winds and flying debris can damage your windows. Look for storm windows that feature tempered glass — it's far stronger than normal glass and that crumbles rather than shatters upon impact. Or consider glass that's built specifically for hurricane protection. These windows typically have a polyvinyl layer sandwiched between two layers of glass for added durability.
Noise abatement: If your home is in a particularly noisy area, storm windows can help mute outside sounds by "trapping" them in the air space between panes. Look for windows that have a high Sound Transmission Class (STC) rating, which indicates better acoustical performance.
