SHGC does not reference single pane, double strength glass, and can be used to calculate energy performance for all times of day and year because it takes the angles of the sun and window treatment into account. Shading Coefficient (SC): The previously used term “Shading Coefficient” has been replaced by SHGC, which is a more useful and accurate way of describing the shading effect of shades and all types of windows and glass.

The lower the SHGC, the more effective a solar screen fabric is at stopping the heat from entering the room. Solar Heat Gain Coefficient (SHGC): Indicates the amount of solar radiation that enters an interior space through both the window and the shade in the form of heat, compared to the total amount of solar radiation. A low figure (<10) indicates effective glare reduction. Best Sellers Customer Service Todays Deals Prime New Releases. Hello Select your address All Hello, Sign in. VLT is impacted by the openness factor, fabric color, and the amount of light that transmits through the fabric. Car Front Rear Window Screen Shade Mesh Cover Windshield Shade Viso : Amazon.sg: Automotive. Visible light transmittance (VLT): The percentage of the available visible light allowed to pass through the solar screen shade and window combined. Fabric color itself does not affect openness across a fabric product line. The more open the fabric, the more solar radiation passes through open space rather than fabric, affecting the overall performance and amount of glare protection, heat protection, and view-through. Openness factor (or Density): Measurement of the relative area of the fabric’s openings, or holes. When you stop to eat or take a break, throw up a reflective shield and lower mounted shades to keep things cool. The total value of all 3 percentages equals 100% of the available solar radiation. Sun Shades Mounted or temporary windshield sun shades for semi-trucks are a convenient solution for blocking harmful sun rays that can overheat the cab and fade the interior. A low percentage indicates fabrics that absorb little solar energy.Īll of the available solar radiation is either transmitted through, absorbed by or reflected by the fabric. Solar absorptance (As): The proportion of solar energy absorbed by the fabric alone. A high percentage indicates fabrics that reflect solar energy well. Solar reflectance (Rs): The proportion of solar energy reflected away by the fabric alone. A low percentage indicates fabrics that reduce solar energy well. Solar transmittance (Ts): The proportion of solar energy transmitted through the fabric alone. The visible and invisible combined, or “spectrum”, make up what we see as light, feel as heat, and UV (ultraviolet) rays that are not seen or felt, but have damaging effects on skin, eyes and furnishings. Some of it is visible, some is not visible. What we call “sunlight” is the energy, or radiation that comes from the sun.
