SuperCapSR™ Exterior Color Technology

Born from military infrared reflective technology, Quanex’s SuperCapSR™ Exterior Color Technology is a patented, co-extruded colorant system, creating a molecularly fused color layer that becomes an integral part of the profile. It absorbs less heat to help prevent heat-related profile distortion, offering outstanding color retention that lasts a lifetime.

Unlike painted vinyl, the tough acrylic color layer is 12 times more scratch-resistant and durable to withstand delivery and installation handling. SuperCapSR™ is field weather-tested in Florida, Arizona and Kentucky and meets AAMA 614 color-hold standards and AAMA 615 durability standards.

SuperCapSR™ is available on a number of Quanex window and door systems, offering bold colors to complement your next-generation, high-performance window system. Special color options may be available; contact your Quanex sales representative for information.
