TILT SASH FUNCTION FOR VENTILATION IN A SECURED POSITION

HIGH STC RATINGS
Up to 41 dB. We achieve this with only 1 sash while others need 3.
As locking points all around the sash perimeter are
engaged, exceptional barriers to air, water and
sound are created.

The four-chambered sashes and frames also provide high energy efficiency.
Frame profiles with different depths provide flexibility for new construction and replacement applications.
Special hardware allows the sash panels to be folded one-by-one to the side of the opening, leaving no post in the middle, to create a full opening to the outdoors.
COMPRESSION SEAL TECHNOLOGY
Compression seals on frame and sashes in combination with multi-point locking hardware keep dust and dirt out and assure optimal water and air tightness, providing outstanding Thermal and Acoustical performance.
Multi-locking mechanisms on the folding sash panels and smooth riding rollers on the top and bottom running tracks protect against intrusion while still allowing for complete clearance when sash panels are opened to the side.
Allowing glass thicknesses from 3/4 to 1 3/8 in (19 to 35 mm), our Infinity Series bi-fold doors can accept a broad range of specialty glazing options to fulfill energy saving needs, including Energy Star requirements.
