Insulating with Draperies
By Jay Steinfeld, No Brainer Blinds and Shades
In prior articles we discussed how blinds and shades insulate your home,
or in some cases how they do not. Cellular honeycomb shades and shutters
are particularly good insulators, while aluminum mini-blinds are ineffective.
Many people prefer the softer and warmer look of draperies. In hot climates
pay particular attention to the additional insulating benefits of draperies.
To maximize their effectiveness, consider the following recommendations.
First consider the fiber content of the fabric. Cottons and wools
are best, while polyester is worst. Those fabrics with blends should have
higher percentages of cotton.
Lining the draperies will do more than any other factor, and there
are many different types of linings to consider. It is best to use thermal
suede lining, which lets light in but blocks out much of the heat. Consider
adding a third layer of fabric between the decorative face fabric and the
thermal suede lining. This is called interlining. Another type of
lining is called blackout lining. This blocks out virtually all heat
and light, so it is an excellent choice. But beware, because it is unwise
to use blackout lining in many types of window treatments since it is somewhat
stiffer than other types and causes the treatment to hang improperly. Also,
many times it is not desirable to have your room totally dark when the draperies
are closed.
To prevent energy from leaking around the drapery, it is best to go as
far past the sides, top, and bottom of the window. Extend the draperies
at least four to five inches past the sides, about 1/2 to 1 inch off the
floor, and extend them as high as visually appealing. Also consider putting
a valance over the drapery, especially one which is mounted at the top with
wood.
Sheers block 60-70% of the ultraviolet light which can severely fade
floors, rugs and furniture, but sheers do not do a very effective job of
blocking heat. When using a sheer as when using draperies, use as much
fabric as possible to get the best coverage. A general rule is using
three times as much fabric as window covered. For example, when covering
a wall that is 100 inches, use 300 inches of fabric. This will also make
a sumptuous, lovely drapery.
There are many different grades of fabrics and linings, and times when
it is incorrect to use some linings. So use care when selecting each. You
may consider using an expert so you will know all of your options and get
the most insulating benefits without sacrificing aesthetics and function.
