OptiCore Technology™ is Quaker’s Patent Pending design technology that allows a single framing system to offer either a wood or aluminum interior with heavy duty aluminium exterior. Quakers’s OptiCore Technology™ creates a thermal break between the exterior and interior framing that can accomplish glass ratings between .11-.29 on Solar Heat Gain and .17-.28 on U-Factor. This meets and exceeds stringent Energy Star code, creating a more comfortable home and saving on energy cost. These ratings are important because most competitor’s aluminum and aluminum clad/wood products can’t even meet Energy Star ratings with their best glass packages.
