InKan Limited operates out of its own 4645 square meter (50,000 sf) facility in Brampton, Ontario. Its resources include in-house metal shear and brake equipment, a skilled welding department and a complete machine shop. InKan's tempering division boasts the most technologically advanced glass processing and handling equipment in the industry. A computerized, tong-free electric tempering furnace guarantees the highest quality of finish available.
Suspended Glass Wall and Glass Canopy:
The ideal solution for a large wall opening: the suspended glass assembly. The glass wall, acting as one unit, hanging from the head of the structure, not only provides a transparent, weatherproof membrane, but also acts as a structural wall. The wall may be interrupted by tempered glass doors or revolving doors to provide access where required.
Kiosks, Entrances and Partitions:
Entrances
Ultra-View by RDM complements any interior or exterior. Tempered glass doors and sidelites of 12mm (1/2 inch) or 10mm (3/8 inch) thickness permit minimal obstruction, creating the ultimate in open concept design. Entrance doors, kiosk boutiques and screens of tempered glass can be custom designed to suit virtually any application. Specially crafted hardware is available in a variety of finishes to enhance the crystal clarity of the glass.
Kiosks and Showcases:
Free standing or top and bottom secured, RDM glass kiosks can transform idle space into profitable, functional space. Choose from InKan's range of expertly crafted metal fittings and either 10mm (3/8 inch) or 12mm (1/2 inch) fully tempered Ultralite glass.
Partitions
To achieve the Ultra-View concept, RDM glass wall partitions can incorporate top and bottom rails or U-channels, either surface mounted or recessed. Not only attractive, RDM glass wall partitions also act as excellent sound barriers.
Glass Doors and Hardware:
Centre hung or offset pivot doors. Ultralite tempered clear glass or tinted glass. Standard or custom hardware. Aluminum, stainless steel, brass, bronze in a variety of finishes. Curved glass sliding doors.
Glass Balustrade:
A custom manufactured handrail in any combination of available finishes and styles, complemented by 12mm (1/2 inch), 15mm (5/8 inch) or 19mm (3/4 inch) clear tempered glass, will ensure lasting beauty, safety and that distinctive look so desirable in any decor.
Spandrel Glass:
OPACI-COAT-300 is a water-based silicone coating designed for use as a coloured opacifier for spandrel applications. OPACI-COAT-300 offers a unique alternative for glass coatings for exterior or interior decor.
Custom Metal and Sculpture:
No job is too small or too large to warrant our superior attention to detail, quality and safety.
Racquetball and Squash Courts:
All walls and fins are 12mm (1/2 inch) clear tempered glass with finished edges. All holes on the playing side are countersunk and dimensioned to receive special flush mounted fittings and hardware. A clear silicone compound is used to bond all joints. No glass-to-glass or glass-to-metal contact is permitted.
