Architectural
Novista Riser doorset with a concealed frame and 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. The Novista Riser Timber door leaf has a solid core and hardwood lippings on all four edges and is very robust and durable. The leaf is fitted with the intumescent strips, locks and flush bolts installed. The Novista Riser Timber doorsets are available with either standard or concealed hinges with a maximum fire rating of FD60S and a maximum acoustic rating of 35dB.
The Novista Riser Timber frame has pockets at the back of the frame to house the concealed hinges and lock box. A section of the wall will need to be cut away to allow the frame to be installed. We recommend that either a double vertical stud is used or a 30mm packer is mounted on top of the stud with the plasterboard for the wall on top. The wall manufacturer should be consulted to ensure compliance with the fire certification.
The Novista Riser Timber doorset has a frame with 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. The frame is manufactured from galvanised steel and this is supplied either factory painted or primed. It is important that the screws that pass through the flanges to
fix the front of the frame into place locate into the stud or a solid structure. If this is not possible because the aperture has been lined with two or more layers of plasterboard, a wider flange can be provided.
The Novista Riser Timber doorsets have been successfully fire tested in various different flexible and rigid wall constructions, and as a result, they can be installed in blockwork, timber stud or metal stud walls appropriate to the required fire certification. The Novista Riser Timber frame has pockets at the back of the frame to house the concealed hinges and lock box. A section of the wall will need to be cut away to allow the frame to be installed. We recommend that a double vertical stud is used or possibly a 30mm packer is mounted on top of a single stud. The wall manufacturer should be consulted to ensure compliance with their fire certification. If a shaft wall system is being used, additional layers of plasterboard can be used. However a wider flange will be required to ensure that the screw fixing at the front locates into the stud.
The doors are supplied as standard with a mortice lock that is operated by a square key or, alternatively, a europrofile version is available. Standard Lock - this lock has an 8mm square follower, which is operated by a T key, and a stainless steel ferrule escutcheon is available either with or without a swing cover. Europrofile Lock - this deadlock is suitable for a single europrofile cylinder, which provides additional security and enables the doors to be integrated into a master key system if required. The inactive leaf of the double doors is secured by using flush bolts top and bottom, which are mounted in the edge of the door leaf.
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. Hanging options include concealed or standard hinge.
Concealed hinges These hinges can be used with the
NFR, FD30 and FD60 doorsets. These allow the door to
open to 180 degrees and are completely invisible when
the door is closed. The hinges are three-way adjustable,
which makes it very easy to align the door leaf and
attain a consistent gap all the way round.
Standard hinges These stainless steel 102x76mm ball bearing hinges can be used with the NFR, FD30 and FD60 doorsets and allow the door to open to 180 degrees.
The Novista Riser Timber door leafs as standard have a primed Kraft paper face, and this can easily be painted on site to match the adjoining wall.
The door leaf can be supplied with a veneered face and matching lippings.
A wide range of high-pressure laminates are available in a solid colour or wood grain finish from either Egger, Formica or Polyrey.
The door leaf can be supplied painted to any RAL colour.
The primed door leaf has a paper face. This is ideal for the wallpaper of your choice to be applied to enable the door leaf to blend in with the adjoining wall.
FIRE - the Novista Riser Timber system has been fire tested by BM Trada to EN1634 for FD30 door leafs up to 2500mm high and 1000mm wide for singles and 2000mm wide for doubles. FD60 doorsets have been tested to 2200mm high and 930mm wide for singles and 1860mm wide for doubles.
SMOKE - the Novista Riser Timber doorsets have a neoprene compression seal that the door leaf closes onto, which prevents cold smoke from passing through the doorset. The doorsets have been tested to the EN1634-3 standard and have an EN13501-2 classification of Sa (cold smoke). The seals have also been fire tested for 1 hour to EN1634 without compromising the fire resistance of the doorset.
ACOUSTIC - the Novista Riser Timber doorset is supplied with a solid core door leaf as standard, and with the perimeter seals it can achieve an acoustic rating of 35dB.
A unique feature of the Novista Riser Timber door frames is that they are supplied in kit form, which results in them being very easy to move around site and store. Door frames up to 2700mm wide are supplied in four sections, which can be assembled in a matter of minutes using our bespoke connecting system. Once completed, the frame is very rigid and ready for installation into the wall. Door frames that are wider than 2700mm are supplied with the bottom and top sections in two pieces to allow for easy transportation and movement on site, and these are fixed together using our simple jointing system.
