Interstate and OKNA Windows "Work-Free" Windows Mean No Scraping, Painting or Repair Ever Again!

The Aluminum Company is proud to install Interstate and OKNA Windows in Raleigh-Durham and across North Carolina. Maintenance-free Interstate and OKNA Windows are constructed of fully extruded vinyl frames and sashes for durability and beauty. No need to worry about chipping, cracking, warping or peeling—ever. Colors are formulated right into the vinyl and guaranteed against fading, discoloring or staining.

All Interstate and OKNA Windows operate easily, even after years of use, thanks to the block and tackle balance. This system guarantees that Interstate and OKNA Windows will always slide up and down easily and stay in the desired position, without ever slipping down, as some older windows do.

Reduce Your Cooling and Heating Bills!

As fuel costs continue to rise, Interstate and OKNA Windows are important tools to help you save money by helping insulate your home against Raleigh-Durham summer heat and winter chill.

Interstate and OKNA Windows offers energy-efficient glass systems that could pay for themselves in the money you save on energy costs, while increasing your home's comfort level.

Choose from Hundreds of Window Designs

Whether the style of your present (or your future) home is traditional, contemporary, split-level, colonial or Cape Cod, The Aluminum Company will help you find just the right Interstate and OKNA Windows for your home’s architectural style.

Choose from single or double hung, casement, bay or bow, sliding windows, picture windows, glass block windows or garden windows. Or add drama with uniquely-shaped specialty custom windows, such as a triangle, or an octagon window in your master bath—or a rounded top window over your picture window. The variety is endless!
