The OKNA B800 Plus is the latest innovation in new construction basement windows. It adds value far beyond its cost. The OKNA B800 Plus differs from conventional basement windows in that it is built on a wide, fully injected mould frame. The "wide-body" frame makes for easier installation in a block and poured wall foundation and it minimizes finishing.

New home construction costs are soaring. Save time and money by turning below ground space into above ground-quality livable square footage. Change your storage space into living space and increase the value of your home. With OKNA Windows & Doors the possibilities are endless.
