Xtratherm UK - Keep insulation locked in rafters
Xtratherm, one of the leading providers of insulation
solutions, has launched an innovative new product for
insulating pitched roofs that provides a robust and
user-friendly way to improve the thermal performance of
a building.
Rafterloc is a BBA-Approved polyisocyanurate (PIR) foam
that is installed concertina style between rafters on
the slope of the roof.
“This new product has been released in response to
demand from customers for a quick and easy way to
achieve required thermal performance in new build and
renovation projects,” explains Danny Kearney Technical
Manager at Xtratherm. “This user-friendly system
features a clever slotting mechanism that allows the
boards to lock between the rafters, ensuring a tight fit
which is a really effective way to reduce heat loss
through the roof. The new product is part of our ongoing
development of a whole range of innovative and
user-friendly insulation solutions designed to appeal to
specifiers, contractors and developers.”
Rafterloc is available in 360 and 565mm widths and 50
and 100mm thicknesses. Each Rafterloc panel has a width
variation of between 20 - 30mm to allow a tight fit
between the rafters.
Rafterloc therefore avoids most problems with
discrepancies in timber widths and spacings that can
result from standard size insulated board and therefore
helps reduce waste on site.
Polyisocyanurate (PIR), used in the manufacture of
Rafterloc, has a closed cell rigid foam construction
that offers excellent insulation properties. This allows
PIR to achieve one of the lowest Lambda Values of any
insulation material and therefore energy efficient roof
systems can be achieved with the minimum of thickness -
a single layer of Rafterloc may be sufficient. However
for buildings that require even better U-values
Rafterloc is recommended to be used in combination with
Xtratherm Pitched Roof Board Thin-R below the rafter,
which also reduces thermal bridging.
Rafterloc is part of Xtratherm’s complete range of PIR
insulation products, which are renowned for their high
quality construction, excellent performance and
durability. As well as offering an innovative product
range, Xtratherm provides expert technical guidance
through an extensive suite of literature, CDs and
website support on meeting the latest building
regulations.
Danny Kearney explains: “Our products are designed to
help developers meet not only current but also future
building performance requirements. There are many
challenges facing the construction industry and our aim
is to provide solutions that make meeting the
regulations as simple and straightforward as possible.”
Rafterloc is manufactured using a blowing agent which
has zero Ozone Depletion Potential (ODP) and therefore
provides a solution to CFC and HCFC-free specification
requirements.
