System Performance
Mechoshade screen cloths are constructed with fiber elements. The system's performance will greatly depend on color and on the openness of the cloth weave. Color is critical when selecting a sunscreen shadecloth because it will affect heat gain, brightness and glare. Light colors are more reflective with lower heat gain and shading coefficients, but with a higher percentage of daylight and solar transmittance. Light colors are difficult to see through due to surface brightness and higher reflectance and transmittance characteristics. They also tend to reflect more of the interior light back into the space. Darker colors provide a better view through the shadecloth to the outside but absorb light and heat, and are less energy efficient than lighter colors. They transmit less light and have a lower surface brightness, which decreases reflectivity and provides efficient glare-free environments for CRTs and work stations. For a more advanced lighting analysis and project specific results, we recommend using the Lightsolve program (under development).

System Description
The screens can be woven using transparent or colored vinyl coated polyester yarns (ThermoVeil and EuroVeil), available in a wide variety of weaves, patterns and densities, to match daylight transmittance of the glazing and to be adapted to the glazing’s orientation. With similar performance characteristics, EcoVeil is a non-PVC shadecloth, offering an optimized environmentally friendly version. Each piece of EcoVeil yarn, which are between 0.25mm and 0.46mm thick, has a thermoplastic olefin (TPO) core of fiber filaments with a TPO coating. This yarn is woven into cloth, which can then be placed over a window, in dimensions of up to 3.2m wide. The TPO material is flame retardant, washable and anti-microbial. Using only TPO, both the excess from production and old shades can be reused; after about 20 years of use, shades can be replaced and the old ones recycled. With a complete cradle to cradle system, each product within the shades is recyclable and reusable. |
