Recently the Pioneer Window Works division of Marathon installed two new motorized FlexShade 2 roller window shades by Draper in the Marathon Building Environments showroom. We used 2 different fabrics, both with Koolblack technology. Koolblack Technology allows glare control with view through benefits of dark fabric. It reduces cooling costs, improves comfort, improves heat control and increases energy saving. Seriously, what more can you ask for….please contact Marathon/Pioneer Windows or come on over to Marathon and see them for yourself.
