Welded Frame and Sash The most preferred construction method of vinyl window extrusions. Significantly stronger than typical mechanically fastened vents. Provides an air-tight seal. Rivnut Fastening This method eliminates the chance of screws stripping the frame or sash. Screws are installed directly into rivnuts which are attached to the vinyl. The screw is applied with threadlocker to prevent loosening. This prevents the loosening of the sash door when opened and closed repeatedly making the vent more durable. Hinges Manufactured with 1/8" aluminum bar stock which is the heaviest material used by any vent manufacturer. Dual Durometer Seal The bubble seal is extruded directly with the sash. We use the largest bubble seal in the industry. This one step process is the key to making an air tight seal.
