Introduction

5. Quadra introduction
www.selo-uk.com Quadra & Una Riser door systems | 9
Quadra combines usability with discreet design to provide easy access and
a completely smooth wall profile, making it ideal for concealing riser doors
and service cupboards in corridors, landings and other access areas.
An introduction to Quadra
Quadra is supplied as an integral, four-sided frame and
door system, pre-constructed to form a single robust
unit. It is pre-made to your requirements so onsite work
is minimal.
The door is hung on a unique pivot system specifically
designed for the application. This robust hinge is fully
concealed and makes the door leaf extremely simple to
remove and re-hang if required.
The doorset is then fixed into the shaft/partition wall
through the perforated flange and fixing holes in
the face of the frame. Once in place, Quadra offers
excellent accessibility combined with solid durability.
Once in place, Quadra can be plastered or tape and
jointed up to the integral stop-beads at the corners of
the frame, creating a perfectly flush profile with the wall.
The system can then be painted with the same finish as
the surrounding wall, creating a consistent, high-quality
aesthetic finish that sets the project apart!

The Una riser door system utilises a timber door leaf with a concealed metal
frame which allows the fitting of standard locks and handles to match in with
the rest of the project.
The Una system is provided as a full doorset with the
frame made to size and supplied as a flat packed kit
prepared for all ironmongery. The door leaf is provided
with hinge cut outs and can be primed for on site
finishing or pre-finished in our factory.
The timber door leaf enables you to fit standard
ironmongery to it such as locks, flush bolts and
handles. Concealed or visible butt hinges can provided
depending on your finish, requirements and the budget.
The frame is a single-piece metal section with a
perforated bead and stop for fixing holes. Once
installed the frame provides a strong and robust clean
edge which can be plastered up to or tape and jointed
to conceal the frame.
Once installed the Una system can be plastered or
tape-and-jointed to the integral stop beads creating a
perfectly seamless finish.
If provided primed the door can be finished along with
the rest of the wall to completely hide the door.

Una door leafs are manufactured from high-density
solid timber core using the latest CNC technology.
Door leafs
Una options
Una doors are made to suit every individual order,
taking into account size, quantity and finish. The
doors are cut out of their original core size and then
calibrated for a smooth surface to take the next stage
of preparation. They are then lipped with hardwood and
veneered with an opaque kraft paper to conceal the
lippings and give a completely smooth finish ready for
final painting.
Using our technologically advanced CNC machinery,
the doors are then cut out for hinges, seals and
other ironmongery where required before being
palletised and sent to site in their ‘ready to fit’ form.

Core types
› Particle – 29KG/sqm
› Solid Timber – 18kg/sqm

The metal frame and timber door leaf can
be provided in a variety of different finishes.
The frames are cold-rolled from
high-performance steel and can
be provided in 2 finishes:
Finishes
Powder-coated
The frame can be pre-finished in a
polyester powder-coated finish to a
standard RAL colour.
Unfinished for site painting
The frame is pre-etched and simply
requires a metal primer to be applied to
the frame before painting. The frame is
usually painted in with the rest of the wall,
alternatively it can be painted separately.
