Clement steel sections are made from recycled material
and in addition the company arranges for all the metal it

new developments launched at Interbuild 2007.
the CAST rooflight is now more thermally efficient
availability of the CAST lightpipe
CAST rooflight reduces carbon emissions
Not surprisingly a great deal of talk at the NEC will concern Part L of the Building Regulations. Clement
Steel Windows Technical Director, Rick Clement, will be pleased to tell many of the visitors that all
insulating glass units glazed into CAST rooflights have an Argon gas filled cavity. Rick said “after Kyoto
the rooflight industry is responding to huge challenges that the government have laid down for
increased energy conservation. Our CAST rooflight is the first in its class to provide an insulating glass
unit with a ‘u’ value of 1.0 W/m2K, not as an optional extra but as standard!”
Clement products are regularly on display at exhibitions around the country, where experts will also
be on hand to offer advice For information on forthcoming events please see

From the established Duette range known for their ‘superior’ quality,
we can now offer you a great choice of colours in two variations.
The Duette blind system is unique in that is has a honeycombe pleat,
which traps in air for added insulation. Using similar technology to our
double glazed units it remarkably keeps heat in, in the winter and in the
summer out…. another step towards helping the environment!
On standard pleated blinds a cord is visible, however the honeycombe
material here allows the cords to be hidden within the blind itself. The
blind also has a pull up cord and lock system.

We have two types of Duette blind available, translucent and blackout.
To help you decide which colour or type is best for you, each fabric
has been tested for three values: reflection, absorption and
transmission. An explanation of these is shown on figure 1 and the
individual values are beside each colour sample.
Every blind comes with a one year guarantee, detailed fitting
instructions and care advice to help promote longevity.

Frequently Asked Questions
Q: How is your rooflight different from other traditional
looking rooflights?
Q: Part L of the building regulations, and ‘U’ values how
has it all come about ?
A: Our rooflights differ in four main ways:
1 We offer 3 rooflight depths to ensure you get the right fit.
2 The thermal barrier between the opening and the closing leaf
assists with insulation
3 The CAST rooflight also has glass units which are filled with
argon gas drastically cutting carbon emissions.
4 The very latest glass units feature warm edge technology, this
improvement prevents a great deal of heat escaping through
the sealant and the spacer bar. All of our glass units are
constructed using this advanced process
5 Finally to assist with maintenance we coat the top surface of
each glass unit with “Rain Racer”™, self cleaning glass solution
keeping the glass brighter for longer.
A: At the CAST rooflight we applaud the government’s objectives
to reduce carbon emissions. We now know for certain how
harmful these “greenhouse gasses” are to the environment.
The revised Part L is one of the package of measures to bring
the UK into line with its “Kyoto Accord” agreements.
A ‘U’ value is a way of measuring heat loss. The lower the
‘U’ value the lower the amount of heat loss.
Q: Like a Velux do I need a flashing kit?
A: CAST rooflights, are traditional building products. We would
always suggest the use of flashing and recommend you take
professional advice. After all every roof is different.
Q: I want a CAST rooflight but I don’t do DIY, how can it be
installed?
A: We manufacture the CAST rooflight as a supply only product,
we do not fit. It is a very specialist job, so speak with a
chartered builder or chartered surveyor for advice before doing
anything. A risk assessment maybe necessary. We can not
recommend an installer but list below two individuals who have
installed our rooflights for other clients around the UK.
Graham from Gloucester 01454 269000
Matthew from Scotland 0845 6015786
Q: How can I buy the highest performing conservation
rooflight at the very best price.
A: Ring us on 01428 643393 and speak to the manufacturers
direct, we don’t deal with middle men, who have already added
on their profit. So we can pass these cost savings on to our
customers.
Q: Do you make your own rooflights?
A: Yes we do, and to the very best quality, both of our factories are
registered to ISO 9001. In manufacturing our own rooflights we
benefit from significant advantages. For example our product
development is easier to implement and we are always striving
to improve the performance of our rooflights as illustrated by
the recent introduction of self cleaning glass, thermal barrier
and the thermally broken ‘T’ section glazing bar.
Q: The CAST rooflight, does it comply with the new
regulations?
A: Yes it does, the glass that we use has a ‘U’ value of 1.0
W/m2K.
Q: What about condensation- possible but increasingly
unlikely?
A: The thermal efficiency of the argon gas filled double glazed
units of the CAST rooflight combined with the thermal barrier
and thermally broken ‘T’ glazing bar which come as standard
with our rooflights make condensation problems virtually a
thing of the past.
Condensation is the water which results from the conversion
of water vapour in the atmosphere. The air which surrounds
us in our homes always contains water vapour, which is
usually invisible. The warmer the air, the more water vapour it
can hold but there is a limit to the amount it can hold for a
given temperature. When saturated air comes into contact
with a surface which is at a lower temperature, the air is
chilled at the point of contact and sheds its surplus water
vapour on that surface.
Please ensure that the entire installation is in accordance with
our instructions.
Q: I have got a slate roof does the rooflight need to be
different?
A: Yes that is why we have two profiles for our rooflights. One for
slate the other for deeper roof finishes such as clay tiles. We
are the only company to offer this option and it ensures that
the rooflight sit flush with the roofline.
Q: Can I have a purpose made rooflight?
A: No problem and choose your own colour if you want, it
doesn’t have to be Henry Ford black.
TAKING CARE OF YOUR ROOFLIGHT
Keep the weatherstripping clean removing any grime, ensure the working parts remain dust
free and regularly lubricated. Clean down the paint surface at least twice a year (polluted or
marine environments will require more intensive maintenance) using warm water with a drop of
detergent such as washing up liquid.
WARRANTY
We offer a 10 year warranty on the paint surface, 5 years for glass and 1 year fittings.
All subject to our terms and conditions which you should read thoroughly. Copy available upon
request or see the website.
