Xtratherm - Achieving lower U-values
Housebuilders and developers looking to achieve lower
U-values within their cavity wall constructions will
find it even easier thanks to NEW Cavity-Plus from
Xtratherm.
Through constant innovation the company has managed to
improve the thermal performance of its Thin-R rigid
insulation from a lambda value of 0.023 to 0.021. The
cavity resistance of the product has also been improved
through the use of an enhanced foil facing.
Part L Revision also places greater emphasis on
Continuity of Insulation in the form of Robust Detailing
and because Cavity Plus includes tongue and groove
construction to all four edges and pre-formed corners it
meets with recommended best practice. Its innovative
pre-formed corners also ensure continuity of insulation
which is now mandatory within the ‘Accredited Detailing’
in ADL.
“This is a major breakthrough in the performance of
rigid foam insulation,” explains Danny Kearney Technical
Manager at Xtratherm. “Cavity-Plus has been released in
response to demand from developers, contractors and
specifiers for more thermally efficient products. It
provides the performance necessary to improve the energy
efficiency levels for new buildings, as well as being
extremely easy to fit. We have communicated the benefits
of Cavity-Plus by stamping the low emissivity foil with
‘achieving lower u-values’ stating exactly what it does
on the foil!”
Cavity-Plus enables developers to achieve the required
lower U-values whilst still retaining a residual cavity
within the wall; the most effective method of protecting
a building from the effects of wind-driven rain. The
product is BBA certified to these new values.
Cavity-Plus is already gaining widespread acceptance in
the building sector because it enables housebuilders to
retain current site practices, including standard wall
thicknesses, whilst still meeting the new regulations.
Danny Kearney explains: “Product innovation is at the
heart of creating energy efficient homes for the future.
As manufacturers of high performance rigid insulation we
recognise our part in providing thermally-efficient
products that enable housebuilders to conform to tighter
regulations as well as complementing both traditional
and new build methods.”
Xtratherm provides a comprehensive range of wall, roof
and floor insulation products specifically designed to
meet Building Regulations and the requirements of the
Code for Sustainable Homes. All products are
manufactured under quality systems approved under EN ISO
9001: 2000 along with ISO14001 and ISO18001
certification.
