Materials |
Aluminium profiles are extruded from alloys
6005 T6, 6063 T6 or 6060 T5 to BS EN 12020,
BS EN 573-3, BS EN 515 and BS EN 775-1 to 9.
Accessories are cast from Zamak 5 or A-S9G03
to BS EN 12844.
All frame gaskets are structural silicone
certifiably compatible EPDM.
Polyamide thermal breaks are extruded from
PA6-6 (0.25 FV).
Screws are torx head austenitic stainless
steel. |
|
Finishes |
Standard mill finished.
Natural self-colour or Anolok anodised in
accordance with BS EN 1273 and BS3987.
Stoved polyester powder coated finishes in a
wide range of colours and in accordance with
BS 6496.
The MX suite is also available in Technal’s
exclusive flecked gloss Cendré polyester
powder coated colours. |
|
Profile Width |
75mm |
|
Construction |
The mullions and transoms are square cut and
assembled using a combination of
factory-fitted cast face-fixed junction
spigots and concealed anti-rotation spigots,
or by transom blocks. This robust
construction offers ease of fabrication,
greater accuracy and enhanced stability.
The mullion jointing uses a specially
designed sleeve spigot for each mullion for
a high quality joint.
All machine operations can be performed on
drill jigs with punch tooling for drainage,
to reduce fabrication time and cost, and
achieve consistent quality. |
|
Performance |
Each individual drainage zone has a series
of bespoke EPDM plugs between the isolators
and pressure plates at each junction,
preventing water ingress and removing the
need for sealant for higher performance.
The MX system has the additional advantage
of secondary mullion drainage to further
improve weather performance and quality.
A PVC perimeter sealing profile ensures damp
proofing at the building interface.
The system is zone drained and pressure
equalised to ensure performance and drainage
efficiency. |

Specification for Curtain Walling. |
|
| |
MX Visible Grid |
|
 |
|
Features |
6mm to 32mm glazing available as a flat
façade or faceted up to 20°.
Superior load distribution with less
deflection across the transoms, allowing the
system to hold large, heavy glazing units.
Projecting top hung open-out, and tilt/turn
concealed vents for natural ventilation
whilst maintaining an uninterrupted flat
façade.
Choice of glazing gaskets as over-sized
vulcanised corners, linear supply, or
made-to-order frames to suit project
requirements. |
|
Construction |
The faceted glazing option uses a standard
cast face-fixed spigot for a facet of ±10°,
and a transom block with specially designed
pressure plates, caps and adaptors for 10°
to 20° facets.
The mullions and transoms are square cut and
assembled using a combination of cast
face-fixed junction spigots and concealed
anti-rotation spigots for ease of
fabrication.
There is also the option of transom blocks
as an alternative to anti-rotation spigots
to meet design and project requirements. |
|
Weather Performance |
The MX visible grid system is thermally
isolated using a 34mm TPE thermal break
between the pressure plate and mullion or
transom. This ensures superior thermal
performance in line with the required
building regulations.
A pressure plate holds the infill in place
with a combination of EPDM gaskets and
allows for zone drainage with pressure
equalisation using punched slots into the
pressure plates and caps. |
|
| |
| |
MX Trame |
|
 |
| |
|
Features |
MX Trame is a further design option,
allowing specifiers to highlight the
vertical or horizontal profiles across the
building envelope. MX Trame Horizontale
can accommodate 6mm to 32mm glazing as a
flat façade or faceted up to 10°. The
concealed vent configurations are top hung
open-out or tilt/turn
MX Trame Verticale can carry 6mm to 32mm
glazed units as a flat façade. Concealed
vent options are top hung or tilt/turn
On larger mullion or transom spans, the
glass deflection is reduced using a
centrally fitted pressure block. |
|
Construction |
Projecting aerofoil transom caps add depth
to the façade whilst slender face trim
gaskets, which are flush with the front face
of the infill, soften the corresponding
vertical or horizontal sections The MX
Trame system is dry glazed, removing the
need for site-applied sealant. |
|
Weather Performance |
A pressure plate on the mullion or transom
holds the infill in place with a combination
of EPDM gaskets and allows for zone drainage
with pressure equalisation through punched
slots into the pressure plates and caps MX
Trame is thermally isolated using a 34mm TPE
thermal break between the pressure plate and
mullion or transom. This ensures superior
thermal performance in line with the
required building
regulations. |
|
| |
MX SSG |
|
 |
|
Features |
MX SSG responds to the increasing demand for
structural glazing to create striking flush
glass façades with visibly less aluminium
MX SSG uses the same grid system as MX
beaded glazing, MX Trame and MX visible
grid, allowing specifiers to vary the
aesthetics of the building envelope without
the need for additional interface detailing
and construction
The system is manufactured in controlled
factory conditions by an approved bonding
specialist to certified standards
A patented ‘hook and toggle’ system
facilitates installation
The double glazed units are bonded onto
the carrier frame with one or two-part
silicone. The external edges are arissed and
a 2mm step to the outer pane allows standing
water to drain away for improved weather
performance
A bespoke EPDM perimeter frame gasket is
fitted to every frame
MX SSG can accommodate 6mm, 28mm or 34mm
structural sealant glazing or 50mm composite
insulated panels
Available as a flat façade or faceted up
to 3º
The glass is supported by a patented
glass security support at each corner of the
carrier frame which allows a maximum glass
weight of 200kg per frame
A choice of fixed lights, top hung
open-out and tilt/turn concealed vents are
available
A single carrier frame can be easily
removed from the inside using a special tool
for replacement glazing. |
|
Construction |
An EPDM internal compression gasket makes
the system fully air tight. There is a
choice of a frame gasket or over-sized
vulcanised corners fitted on site Carrier
frames are fitted onto the curtain wall grid
using the ‘hook and toggle’ system
The carrier frames are mitre jointed
using an epoxy-bonded and mechanically
crimped corner cleat for a robust
construction. |
|
| |
MX BG |
|
 |
|
Features |
MX BG has an externally beaded frame option
to create a ‘picture frame’ appearance MX
BG uses the same grid system as MX
structural glazing, MX Trame and MX visible
grid, allowing specifiers to vary the
aesthetics of the building without the need
for additional interface detailing and
construction
A patented ‘hook and toggle’ system
facilitates installation
The system is dry glazed onto carrier
frames in the factory
MX BG can carry 30mm to 36mm glazing
Available as a flat façade or faceted up
to 3º
Externally glazed, the top and bottom
beads are pop-riveted to the fixed frame for
additional security
A choice of fixed lights, top hung
open-out and tilt/turn concealed vents are
available
A single carrier frame can be easily
removed from the inside for replacement
glazing using a special tool. |
|
Construction |
An EPDM internal compression gasket makes
the system fully air tight. There is a
choice of a frame gasket or over-sized
vulcanised corners fitted on site. Carrier
frames are fitted onto the curtain wall grid
using the ‘hook and toggle’ system
The carrier frames are mitre jointed
using an epoxy-bonded and mechanically
crimped corner cleat for a robust
construction. |

MX Sloped Glazing |
|
 |
| |
|
Features |
The MX curtain walling system allows sloped glazing to be
created in MX visible grid or MX Trame
Verticale These options give specifiers
the flexibility to construct sloped roofs,
atria, canopies, valleys and pyramids, which
are fully compatible and visually consistent
with the vertical façade.
MX Visible Grid:
A special transom cap for the horizontal and
vertical profiles reduces the collection of
water on the slope
The rafters and transoms are square cut
and assembled using a penetrating transom
principle.
MX Trame Verticale:
There are vertical caps and silicone
sealant on the transom with pressure blocks
to prevent deflection under negative wind
load pressure
The double glazed units should be
manufactured using structural silicone
sealant
A minimum slope is available of 10º for
single glazed units and 15º for double
glazing. |
|
Construction |
The 8mm to 32mm infill is held by horizontal
and vertical pressure plates for the visible
grid system and by vertical pressure plates
and horizontal pressure blocks for MX Trame
Verticale. |
|
Weather Performance |
Drainage is achieved from the transom ends
through the rafters The grid system is
glazed with an EPDM gasket to the inside and
butyl tape to the outside. MX Trame
Verticale has an infill gasket and silicone
on the transoms. |
