From increasing energy efficiency to creating a barrier for smoke, sound and light thresholds serve many important purposes. That’s why it is important to standardize on top quality materials and construction. Zero thresholds are designed to stand up to the demands of heavy traffic openings and those with extreme temperature differentials. The heavy-gauge material allows you to drill and screw our thresholds directly into concrete without the difficulties common when using lighter commercial materials, such as buckling under heavy loads or loose screws.

Features:

• Energy-efficient thermal-break thresholds specially designed to prevent the transfer of outside temperature and frost to the interior side of the door
• Adjustable-width systems features threshold rests that interlock with various size plates. Much easier to trim and fit than conventional, single-size cast-bronze thresholds. Install without exposed screws on the base for better aesthetics and durability
• Extruded bulb finger (EBF) double sealing system designed to ensure an airtight seal even when doors are misaligned because of poor installation or slightly warped. If the door fails to make contact with the bulb in this neoprene gasket, the extra “finger” acts as a supplemental seal to block air flow

Types:

• Saddle thresholds: are the most commonly used because they are beveled equally on both sides and come in varying widths and heights
• Half-saddle thresholds: are raised on one side to ease transition at the sill
• Offset thresholds: are non-symmetrical to address areas where uneven surfaces meet
• Rabbeted thresholds: incorporate a ridged design to seal against the door to provide superior insulation
• Thermal break thresholds: are specially designed to prevent the transfer of outside temperature and frost to the interior side of the door
• Carpet divider thresholds: designed to be used as a divider between two floor finishes
• Adjustable thresholds: Interlocking plates and noses provide flexibility and can be customized to meet the unique requirements of your opening
• Traction tread adjustable thresholds: used to enhance safety with formulated rubber inserts or with an epoxy abrasive (non-slip particles) bonded into the grooves
• Ramps: provide a gradual incline to ease the transition between ground and sill for accessibility
• Interlocking thresholds: allow you to interlock with an angle or hook to prevent water infiltration
• Adjustable interlocking thresholds: allow you to mix and match components to customize a solution
• Specialized threshold solutions: offer a variety of solution sets are available for various applications from bulkhead systems, roof curb thresholder, wheel chair accessible showers and more
