Phifer SunTex - is a fabric woven of extremely strong and durable
vinyl-coated polyester yarns. The uniform weave design offers excellent
outward visibility and good ventilation. Shading is approximately 80%, and
SunTex is available in a choice of four earth tone colors. The fabric is also
pet resistant making it ideal for use in doors and full-length screen panels.
The chart here shows a window with SunTex installed.
In midsummer as much as 230 BTUs can fall on each
unprotected square foot of glass.

With SunTex installed, up to 80% or even 90%* of the sun's
heat and glare is reflected, absorbed and dissipated before
it strikes the window.
Extremely durable...also pet resistant
Excellent outward visibility
Protects against fading and sun rot
Provides daytime privacy
Lets in soft light and breezes

* Super Solar Screening Fabric.  (Slightly more expensive than SunTex fabric)
Be careful when choosing a company to make and install solar screens.
To achieve the best efficiency possible from a solar screen, it needs to be mounted on
the window so that the fabric side of the screen is turned to the outside, or as far from
the glass as is possible, to create a proper air gap between the fabric and the window
glass.  Many of the dedicated solar screen companies in the area are whipping up
screens as fast and as cheaply as possible, often using thin 3/4" wide frames that are
meant only for half screens, and because many do not trim off the excess fabric flush
with the screen frame, they are unable to mount the solar screens in the correct
orientation without showing the sloppy workmanship.  Only when grid bars are
requested should the screen be turned around backwards, sacrificing efficiency for
looks.  If the fabric is touching glass it can actually heat up the glass rather than shade
it, causing the window to fog prematurely.  
We have also repaired a number of broken windows cause by solar screen
companies who have carelessly run screws into the edge of the window glass.  Often
times the home owner is unaware that the window was cracked by the screen
installer because the crack doesn't start to run across the window until the house
shifts or the wind blows hard enough against the glass to start the run.
Because our screens are made by a quality distributor, we may not be the cheapest in
town.  Our company values quality products and installations that will outlast our
competitors' low prices!
