THE NOVISTA RISER DOORSET WITH A TIMBER DOOR LEAF HAS BEEN DEVELOPED TO HELP BLEND ACCESS AND RISER DOORS INTO THE ADJOINING WALL SO THAT THEY ARE VIRTUALLY INVISIBLE WITH NO ARCHITRAVE, AND THE DOOR FRAME CONCEALED WITHIN THE WALL.

The Novista timber riser option incorporates the same concealed frame section as its steel counterpart but uses a solid timber leaf. The solid leaf allows the use of different ironmongery styles to match the remainder of a building and also gives compliance to DD171 mechanical strength standards (Severe).

The timber leaf also allows more face finish options other than a primer or full PPC finish. The use of veneer, laminate or wallpaper facings further enhances the design possibilities within a space. The timber leaf is rated up to FD60 (fire) and 35dB (sound).

NBS Specification

The Novista Timber Riser is provided as a doorset with all recessing for locks, hinges and flush bolts completed in the factory, saving time and money and minimising the reliance of labour on site. The option of a 3 sided frame allows the door to be used for more conventional methods also other than a typical riser.

Novista Riser Timber Introduction Video

Perforated frame

The Novista Riser frame has a perforated flange with an integral corner bead that sits on the face of the plasterboard or block wall, and this is then plastered or tape and jointed.

Easy assembly

The frame can be assembled in a matter of minutes using our unique connecting system. Once completed, this is extremely rigid and ready for installation into the wall.

Configurations

The Novista Riser steel system is available as a single, double, or triple doorset, ensuring that the opening size can be maximised.

The doorsets are also available with a three-sided frame that has no threshold allowing easy uninterrupted access into rooms with no unsightly frame underneath the door.

Locking

The doors are locked using a mortice lock that is operated using either a square key or a europrofile cylinder, which provides additional security, and this can be integrated into a master key system if required.

Hanging

The Novista Riser Timber Doorsets are available with either standard or concealed hinges for FD30 and FD60 doorsets, and these are fixed into pre-prepared cutouts in the frame and door leaf.

Both the standard and concealed hinges allow the door leafs to open to 180 degrees.

Performance

Smoke

Tested for up to 1 hour under conditions of EN1634 without compromising fire resistance.

Finishes

The standard door leaf has a primed paper face which has a similar texture to plaster board, and this can be easily painted on-site to match the adjoining wall.

Alternatively, the door leaf can be supplied pre-painted to any RAL colour or with a veneered, laminated, or PVC facing.

Installation

The Novista Steel Timber Steel Doorset frames are supplied in sections for easy handling on site and can be assembled in a matter of minutes forming a rigid construction which can be fixed into either a stud or shaft wall which can be either skimmed or tape and jointed.

The doors leaf’s are supplied prepared for the locks and hinges and are very simple and easy to install into the frames.
