Carinya – Clearly Better

The Carinya Select Bi Fold System is a unique combination of form and function, with flat sill provisions for smooth accessibility and optional mid rails with multi-point locking in a range of opening configurations.

Consisting of a modern designer look, the Carinya Bi Fold extrusions are a consistent 85mm wide face on both the stiles and rails. This allows a balanced visual face and allows a vast array of hardware lock options. Combined with optional spigots, these door panels are superior in strength and performance.

With the use of the innovative Centor Bottom rolling hardware the system overcomes the requirement for any structural beam as needed in a top hung Bi Fold system. This is ideal for the new or renovation market that want an Alfresco style opening without the additional cost of a structural beam.
The Carinya attention to detail includes concealed flush bolt brackets, reducing visible fixings, as well as custom extrusion design allowing for clean interaction with door hardware.

The Carinya Bi Fold system has been fully tested to comply or exceed the new changes in the Australian Standard AS2047-2014 Windows and external glazed doors in buildings.

Streamlined Hardware

The sashes feature an commercial door spigot, allowing a strong and robust panel for enduring use making the panel free of twist and movement.

Standard lock hardware options include ALSPEC’s custom Australian made Killara Furniture, combined with Lockwood’s proven Optimum mortice lock. Fitting snug within the stile and allowing an extended backset; this lock removes the common issue of minimal key distance to the jamb. Other lock options include commercial locksets and furniture for a complete choice, as well as two and four point locking on the active leaf panel.

Custom flush bolt guides have been designed to remove visible fixings from the extrusion faces, allowing a tighter integrated sealing saving potential energy costs while giving a professional, uninterrupted clean visible surface.

Killara Xtra Furniture allows for an internal snib option with lock indicator and two or four point locking for all configurations.
