Solar properties are important when selecting screen fabrics, as the
efficiency of the fabric depends on the colour chosen.
When selecting a fabric, there are a number of factors that should be
All Texstyle screen fabrics are tested in the USA by Matrix Inc, when
these tests are conducted the fabric and glass are tested together.
Ts Solar Transmittance
The amount of energy transmitted through the fabric.
Rs Solar Reflection
The proportion of solar energy that is reflected by the fabric. The
lighter the colour, the better the reflection. Eg. Solar View White
reflects 64%, while black reflects only 6%
As Solar Absorbance
The proportion of solar energy that is absorbed by the fabric. The
darker the fabric the more solar energy that is absorbed by the fabric.
Note: The sum of transmittance, absorbance and reflection always = 100%
(Ts + As + Rs = 100).
The amount of UV that is transmitted through a fabric. A Tuv of 7 means
that 93% of the UV is blocked. This is important when considering
protection of flooring, furnishing fabrics and furniture against
Is the amount of glare a person receives through the fabric. The Green
Building Council rating system requires a Tv of less than 10. Glare
increase in winter when the angle of the sun lower.
O-F Openness Factor
This measures the proportion of holes in a woven fabric. 5% openness =
5% holes in 1 sqm. The more open the more solar heat admitted through
the fabric. Openness also aggects the degree of visibility.
