is growing, with more installers introducing
the product into their offering, and therefore
more installations taking place, it is becoming
more important to ensure that the design
and specifications of the systems meet up to
the highest standards
So, what lurks beneath those tiles?
And what makes the Icotherm system so
unique?
Anne-Marie Busch, Marketing Manager,
explains.
Mostly, this product is referred to as a tiled
roof, sometimes a warm roof. From my own
experience I can say that this has been driven
by the need to come up with a descriptive
that would best get across what this roof
offers. Here at Icotherm we generically refer
to our roofs as “solid” as we in fact use two
very specific roofing constructions within
our range.
A cold roof construction: and yes, cold
roof does not exactly give all the right feels,
hence opting to go for “solid”. But what does
it mean?
“A cold roof has the thermal insulation
layer located between the ceiling joists so
that everything above the insulation (rafters,
any roof space) will be colder than the living

space below it. As can be seen from the
illustration (cross section 1), that is how the
Icoroof, Icoview and Ico600 are constructed,
ensuring the empty spaces are well
ventilated (as a traditional roof would be)
to avoid condensation. By using 155mm EPS

insulation we ensure that the “cold” from
this roof stays well away from the room.
On the other hand, you can use a warm
roof construction. “I thought all the tiled
roofs are “warm”, I hear you say… Well,
no… and that is why it is so important to
understand that those terms actually have
very particular meanings.
A warm roof is a type of roof
construction which has an insulation layer
above the rafters, and immediately below its
weatherproof membrane.
The illustration (cross section 2)
highlights how this works for Icospan, our
flat roof solution. By using EPS insulation,
both for the flat ceiling section, the ladder
frame for the lantern, we have designed a
simple to install yet highly effective flat warm
roof offering.
So in summary the Icotherm roofs use both
constructions, to suit specific roof styles. They
are specified to the highest levels to guarantee
performance:
