The
Granada Range:
 The
exclusive Granada range of secondary glazing
is supplied fully assembled and comprises
an aluminium outer frame joined to a seasoned
hardwood surround which allows for a neat,
unobtrusive installation even in the most
difficult situations. A range of hardwood
sub-frames and scribing trims can be used
to assist face fixing, reveal fixing and the
coupling of units. This allows the satisfactory
refurbishment of our largest primary windows.
Suitable for all types of premises including
grade one and two listed buildings, schools,
colleges, hospitals, universities, hotels
and commercial buildings i.e. offices.
The
Granada System:
Better by Design
We have a comprehensive
range of styles to suit just about every application,
including Horizontal Sliders, Hinged Units,
Fixed and Lift-Out Units, Vertical Sliders
as well as Balanced Vertical Sliders and Tilt-in
Balanced Vertical Sliders. We can supply frames
in white, silver or brown as standard and
can accommodate any R.A.L. colour upon request
to suit individual requirements. We can also
provide a wide range of glass types such as
clear, patterned, toughened, laminated and
acoustic. Whatever your requirements you can
trust it to Granada.
Insulation
Efficiency:
The Granada range of secondary glazing is
renowned for its thermal efficiency. Varying
degrees of improved thermal insulation can
be achieved by using such glasses as Pilkington
K and Low E. If glass is thermally at risk
then care must be taken to specify toughened
glass. The harmful effects of ultra violet
radiation can also be reduced whilst letting
in solar heat. In addition specialist films
can be adhered to the glass to further increase
thermal insulation whilst adding to the security
of the product and the premises.
Noise
Reduction:
Granada's units have been tested for sound
reduction at the AIRO Acoustics Laboratory
( an accredited NAMAS Testing lab, number
0483 ) in accordance with BS2750: part 3 and
BS5821: part 3 1980 : 1984, using a purpose
built sound transmission suite. The findings
of these tests can be seen by clicking Here.
These tests were carried out in November 1997
as part of Granada's on-going research and
development programme.
The Product
 Due
to the characteristics of the existing primary
window, the Balanced Vertical Slider is the
most complex type of secondary glazing system.
It is applied generally to older properties.
It is particularly suited to the refurbishment
and upgrade of the nation’s architectural
heritage.
How It
Works
The individually pre-tensioned
spiral spring balances control the motion
of the sash, enabling infinite vertical positioning.
This design provides ease of movement and
has been specially developed to withstand
decades of wear and tear. Tilt in versions
can be pivoted through almost 180 degrees.
This is especially useful for cleaning but
just as importantly can be crucial when considering
fire escape requirements. All variations of
Granada’s exclusive secondary glazing
styles are completely compatible. Each type
can be easily used with another no matter
what the application may be.
