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.
Commercial and institutional facilities can benefit from using ZERO for both interior and perimeter applications. Solutions are available for a variety of applications, including:
A variety of types of thresholds are available to accommodate the specific needs of your application. With unique features such as:
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.
Non-slip epoxy abrasive (E or EL) Thresholds can be ordered with non-slip epoxy abrasive particles bonded into the grooves, with (EL) or without (E) photoluminescence for exit path markings. The tread provides a coefficient of friction of 1.02 dry and 0.98 wet to comply with ADA, OSHA and most local building code requirements.
Full body strength (V3) An aluminum composite filler containing aluminum oxide and silicon carbide. Available as option for most profiles, with no requirement for customized extrusions. Ideal applications include: heavy commercial traffic in supply rooms, manufacturing plants, schools, cafeterias, automobile dealers, hospitals, industrial facilities.
No holes (NH) Models supplied standard without mounting holes are noted on the product pages. All other models are supplied standard with mounting holes. Specify NH to order models without mounting holes drilled.
