It’s one thing to hang thermal drapes during the colder months. The curtains, which are often Custom Made and lined on the back with a special fabric that helps to insulate the window space, can be very effective at keeping out drafts of cold air.
However, thermal drapes can also be very effective during warmer months, helping to prevent hot air from outside from being drawn in to your living space, thereby reducing the benefits of air conditioning; the cooled air from your home can also leak the other direction.
And it’s not just a matter of providing protection against gaps in windows, frames and doors. When air conditioning and heating units are run, a buildup of negative pressure can occur when drafts allow too much air to leak out of a room. This, in turn, can cause a situation in which your climate-controlling appliance is less effective than in a normally pressurized atmosphere.
According to SFGate.com, there are more reasons for choosing thermal drapes for both summer and winter:
Thermal drapes use a backing material that does more than add another layer of cloth to trap air and stabilize its temperature. The lining typically consists of a foam substance that’s meant to provide extra insulating power as well as cut down on the annoyance of outdoor noises.
The material is also usually designed in such a way as to allow the warming rays of the sun to heat a living space on cold days, and to prevent their entering the room on warmer days. This helps your furnace or air conditioner do its job without being forced to overwork itself – wasting energy and money in the process.
On “in-between” temperature days when you may want a partial amount of sunlight to warm a room on an unusually chilly summer’s afternoon, you can adjust the opening of thermal drapes to suit your personal comfort zone. Similarly, you can close the opening to proportionately cut down on solar heat gain on a warmer summer’s morning.
