Overview
Awnings are also a practical investment that can slash your
energy bills, as well as protect your furniture, floors and carpets from the
sun's harsh sun rays.
In a typical building, more energy is lost through glass doors
and windows than through any other construction element. While window films and
tinted glass will reduce heat gain and glare, awnings accomplish the same
purpose--and substantially boost energy savings. Studies by the American Society
of Heating and Air Conditioning Engineers reveal that when the sun shines
directly on south-facing windows, fabric awnings reduce heat gain by 55 to 65
percent. For western exposure, the reduction in heat gain is 72 to 77 percent.
Considering an addition to your home? A canopy over your deck or patio
offers a long-term solution to needed space at a lower cost. It also will shade
your deck from the sun, and provide outdoor protection on rainy days. You will
want to consider all angles when selecting awning. Style, venting, fabrics and
color selection all effect the energy saving performance of the awning. See our
"Questions to ask an Awning Company".
Style
It's important to select a style that will accommodate how
much the sun penetrates the windows. For northern and southern exposure, sides
may need to be added to the awnings for additional protection. For eastern and
western facing windows, less protection is necessary. Seasons also will make a
difference. In order to take advantage of the sun's warmth, some awnings are
designed to roll up and out of the way. Further, frames can be designed to
accommodate casement windows.
Venting The awning design creates
more air circulation to dissipate heat buildup. Select a shape that best suits
the windows being protected, as well as the orientation of the windows.
Fabrics
Today's fabric advances have been fueled in part by
improved synthetic yarns as the basis for many laminated fabrics, giving them
greater strength and flexibility Coatings, laminates, and top coatings are common
methods to equip fabrics with protective qualities.
See our Fabric Page for more Information.
Color
Color choice and types of material are important
energy-saving considerations. Awnings with low solar-absorbing surfaces (white)
maintain temperatures closer to the outdoor air temperature. As a result, air
temperature under the awnings isn't raised appreciably. Awnings that absorb
solar radiation (dark colors) may need to be vented to reduce radiation and heat
build-up underneath the awning.
