Woven from vinyl coated polyester yarns, ThermoVeil® and EuroVeil® shadecloths are available in a wide variety of weaves, patterns, colors and densities designed to match the daylight transmittance of the glazing and the glazing orientation. Used in recommended densities, ThermoVeil and EuroVeil provide a significant reduction in solar heat-gain and greater comfort from the radiant component of sunshine. No other roller shade manufacturer provides the extensive shadecloth options and performance that MechoShade does.
