Glare and Lower Your Electric Bill
Living in Southeast
Louisiana means two things every summer: great food, and high
electric bills from running the air conditioner. But what you
may not realize is that improving your home's look can also
lower your utility bills.
We can offer you a wide
variety of window blinds, shutters and shades
to choose from. We not only help you pick out the window
covering that best matches your home or businesses, but can
keep you informed of which shades or blinds are best for
blocking harsh light and dangerous UV rays.
Need products installed? We
can help with that too. Our team of expert installers are both
insured and certified. Below you will find more details on

Energy Efficient Window Coverings
Southern Blinds & Shutters
carries a variety of energy efficient window covering brands,
but the following product details and ratings are for the
Hunter Douglas line.
When an energy-efficient window covering blocks solar energy,
you'll feel a difference. Almost the same difference between
being in direct sunlight, and being under the shade from a
tree. Certain Hunter Douglas products can cut solar heat
gain through your windows by up to 80%. This means not
only can you be more comfortable indoors, but can lower
Energy-efficient Hunter Douglas products can help you save
energy and money in three ways: insulation, solar heat control
An insulating window covering works in both winter and summer
to reduce heat transfer through the window. In winter, the
window covering slows heat transfer out the window, keeping
more warmth inside. In summer, it slows heat transfer into the
home, reducing the need for cooling.
>> Solar Heat Control
In summer (or year-round in hot Louisiana), solar heat control
becomes more important than insulation. Solar heat is brought
into the home by direct or reflected sunlight.
The sunlight becomes heat when it warms the air and
furnishings in its path. The warmed furnishings in turn give
off heat to the room. To stay comfortable, the warmed room
must be cooled, requiring more electricity (and more cost)
than would be needed if the solar energy had been properly
controlled by window coverings.
A big part of solar heat control is reflecting the incoming
sunlight back out the window. For this reason, a white or
light-colored streetside color is preferred. Darker colors
tend to absorb the solar energy, and then radiate it as heat
into the room. Solar heat gain is also great in winter to help
heat the home.
Another important energy-related function of window coverings
is to diffuse incoming sunlight to soften it and bring it
deeper into a room. This function is called “daylighting.” In
addition to reducing glare and improving visual comfort,
daylighting can sometimes save energy by reducing the need for
During the winter season, there’s an immediate reduction in
radiant heat loss to cold window glass, which helps you feel
warmer. Here’s how it works:
All objects (including
people) give off and receive radiant heat.
When people give off more
radiant heat to cold glass than they get back, the net loss
can feel like a chilly draft, even if the window is tightly
But when the new shades are
lowered, your comfort level is suddenly increased.
When you lose enough
radiant heat to feel cold, that's usually when you turn the
heat up. This eats up energy resources and adds to your
electric bill. But when a well-insulating shade minimizes
radiant heat loss, it means you can turn the thermostat down,
saving both energy and money.
Controlling Other Types of Energy
In addition to providing insulation, solar heat control and
daylighting, window coverings can help control two other types
of energy: ultraviolet light and sound.
>> Ultraviolet Protection
Ultraviolet (UV) light is an invisible part of sunlight.
Because UV damages furnishings, it is sometimes called the
“invisible enemy.” Over time it fades furniture, upholstery,
wood flooring, drapes, carpet and art.
But window coverings can be very effective in blocking UV
rays. Most Hunter Douglas products actually block over 95% of
harmful ultraviolet rays when fully closed.
>> Sound Absorption
Soft window coverings can absorb up to 70% of sound energy,
which helps keep the inside of rooms more quiet. But hard
window coverings reflect most sound. This means that it can
help keep out exterior noise, but won't dampen indoor sounds.
Below you will find Energy Efficiency Charts that provide star
ratings for the five product attributes that relate to energy:
insulation, solar heat control, daylighting, ultraviolet
protection and sound absorption.
These Hunter Douglas
products have been rated on a five-star scale. Five stars
means excellent performance, one star means very little or no
contribution to performance. In some cases, certain features
or colors can change a product's rating.
