Clean Design with Modern Curb Appeal
The OKNA Casement 700 offers slim sightlines and unobstructed glass, making it a beautiful fit for bathrooms, kitchens, bedrooms, and even stairwells. Its minimalist look works with both traditional and contemporary homes.
Airtight Performance with Compression Seal Closure
Unlike sliding or double-hung windows, this model uses compression-seal technology for maximum protection against air and water infiltration. It delivers some of the lowest air leakage ratings in the industry, enhancing both comfort and efficiency.
Nail Fin Configuration for New Construction
The 700 comes with a factory-applied nail flange, allowing easy and secure integration into framed openings. It’s a top choice for new builds, additions, and window wall assemblies where performance matters from the start.
