Window features & options
Multi-chambered hollows in frame and sash create greater insulating and structural value.
Where the sash meets the sill we use a superior bulb seal which acts similar to the gasket on your refrigerator, providing a tight seal against water and air infiltration. This foam seal has a memory that will keep its shape even after months of being compressed.
