GETTING WARMER…
The Icotherm solid roof technology– what’s in it?

As the tiled roof category is grow-
ing, with more installers introducing the
product into their offering, and there-
fore 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 Man-
ager, 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 “sol-
id”. But what does it mean?
“A cold roof has the thermal insula-
tion 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 illustra-
tion (cross section 1), that is how the
Icoroof, Icoview and Ico600 are con-
structed, 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 con-
struction which has an insulation layer
above the rafters, and immediately
below its weatherproof membrane.

The illustration (cross section 2) high-
lights how this works for Icospan, our
flat roof solution. By using EPS insula-
tion, 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:
• Timber, a material with thermal
conductivity of only 0.16 W/m2k,
simplifies the process of insula-
tion and ventilation – against an
aluminium frame), as it does not
require cloaking.
• Premium C24 building grade timber
and 155mm EPS boards guarantees
the structural integrity and U-Value
performance (0.18W/m2k, which can
be brought down to 0.12W/m2k with
the use of insulated plasterboard,
ideal for the Scottish market).
• Designed either with a fully venti-
lated “cold” roof construction, with
airflow circulating over the eaves
and through the entire roof, or with
a “warm” roof construction, ensur-
ing condensation will never be an
issue.
• Pre-fabricated pods and pre-cut
insulation provides a solution that
goes up quickly (an average sized
roof should go up in 2 hours, with
the waterproof membrane on)
• 155mm fully recyclable, rigid EPS
insulation
And did you know?
• CRA (Condensations Risk Analysis)
checked and approved.
• Beams and insulation pre-cut to size
• Cut tile service available for shingle
tiles
• Tiles delivered with the roof
• Fully labelled components for a wor-
ry-free installation
• Building Control Compliant
• We can design gable roofs without
tie bars
