Window shades window blinds control glare solar control
Reflex-Rol UK are manufacturers of high
performance solar and glare control systems.
Different materials may be selected according to
the requirement to reduce heat gain, remove solar glare, improve
visibility or insulation, and the specific location and nature of
the premises.
General Information
Why do you need solar and glare control?
In short, we need to control the solar heat
entering our buildings and prevent light entering via windows being
the source of glare on our computer screens.
Solar Heat Gain can make us uncomfortable in the
workplace, and trying to achieve an ambient temperature of 21.5° C,
as stipulated in current E.U. Health and Safety directives, can be
difficult given today's building designs favouring large expanses of
glass.
Cooling systems are expensive to install,
maintain and run, and in context of climatic change, their emissions
are not environmentally friendly. Without doubt, it's better to
prevent excessive heat gain, particularly when this can be achieved
with a flexible (virtually) non energy consuming shading system.
Depending upon which Reflex-Rol shading material is chosen, more
than 80% of the solar heat energy projected at a window can be
prevented from entering a room.
Example: A modern office building can easily
experience heat gain of 50 KW on a single facade. The installation
of Reflex-Rol shading could cut this by 40 KW. That is the
equivalent of turning off 40 single bar electric heaters. Given the
relatively high ambient temperatures of this country, cooling 1 KW
can consume 2 to 30 KW of purchased power (not cheap) and every 1 KW
hour of electrical energy causes a gas fired power station to
produce about 0.43 kg of CO2.
Glare Control has become more important with the
deployment of every additional VDU. 30000 movements of the eye
(contractions and dilations of the pupil) per day can rapidly lead
to fatigue and eye strain in your operatives if widely contrasting
levels of light exist in the workplace.
Similarly, bad posture and the resulting strains
on the body is a common complaint as operatives adjust their
position in relation to the VDU to avoid glare. Such problems could
be overcome by stopping the natural light entering a building
altogether and replacing it with artificial light. This however
incurs costs through electricity bills, greater heat and the loss of
the benefits of natural light, together with contact with the
outside world.
Research has shown that ideal working conditions exist with lighting
levels between 200 cd/m2 and 400 cd/m2 (cd = candela) in conjunction
with Lux levels (ambient light levels) of between 500 to 600.
A shading system delivering a light transmission
(T65 ) of 3% or less can achieve these levels with natural light.
A common misconception is that solar shading is
only for the summer months. Whilst true in respect of heat gain,
glare is noticeably worse in winter months, since the sun is much
lower in the sky, and will penetrate far deeper into a room.
The different requirements on East, South and
West facades may be obvious, but the 'no blinds to the north'
attitude can be totally wrong as ambient light and reflected glare
may still cause a significant problem.
