Comar Architectural Aluminium Systems

Introduction  Comar is one of the 
largest privately owned commercial 
architectural systems companies in 
Europe. It designs, develops and 
manufactures its own systems which 
comprise a huge array of extrusion 
profiles and components. This offers 
the specifier the flexibility of design 
options at realistic cost.
A continuous research and 
development programme ensures 
the company's products are at the 
forefront of the latest technology 
and its range expands to offer new 
design and construction options.
Comar products are mutually 
compatible.

Buildings), the GAI (Guild of 
Architectural Ironmongers) and the 
CWCT (Centre of Window and 
Cladding Technology) and is an 
associate member of the National 
Association of Shopfitters.  
All systems conform to many of the 
requirements of BS 4873.
Green issues  Aluminium is 100% 
recyclable and can be recycled 
endlessly with no performance loss. 
It is highly sustainable with over  
300 years worth of bauxite reserves.
 
Comar 2 aluminium window 
walling 

Applications  Comar 2 is suitable 
for new and refurbishment  
medium-rise applications and higher 
stairwells whether internally or 
externally glazed.
Description  A cost-effective 
alternative to curtain walling,  
Comar 2 is a fully thermally broken 
system. It comprises system profiles 
and components with variable 
corner angles. 90

o

 and 135

o

 returns 

are enabled and sill sections provide 
drainage to the exterior.
It offers the facility for expansion 
and is suitable for a number of 
glazing options of thickness ranging 
from 4 - 71 mm.
Centre-hung doors with hanging 
stile fingerguards are available.
Composition, manufacture  
Box sections are formed from 2-part 
channels and plate mullions to form 
modular sash construction. 
Internal glazing uses 15 mm high 
beading; external glazing, used 
where floor beams and partitions 
prohibit internal glazing, utilises a 
45

o

, 15 mm high bead.

Comar 6 is available either for  
ladder frame or stick build 
construction. 
Applications  When used for ladder 
build, Comar 6 is suitable for 
medium-rise, new build or 
refurbishment projects. When used 
with stick build it may be used for 
projects rising to any level and for 
inclined façades and roof glazing.
Description  Corner mullions adjust 
to give returns of 90

o

 - 135

o

.  

A selection of face caps, including a 
transom cover cap with integral drip 
that prevents water staining, give 
façade options. An internal 
pressure-equalised system ensures 
drainage is to the exterior. 
The framework is insulated by a 
thermal barrier in the pressure plate 
glazing. It allows for vision panels, 
glass pressings, spandrel panels 
and opening vents to be glazed-in 
without cutting.

Construction is either in frame 
format with elements joined by 
stainless steel screws driven into 
integral screw receptacles or 
on-site. 
Glazing is vision glass or spandrel 
panels set dry against EPDM rubber 
gaskets in drained and ventilated 
rebates. This is 6 - 37 mm thick for 
ladder frame and 3 - 50 mm thick for 
stick build.
