Isover, the leading developer of sustainable insulation solutions
designed to protect both the natural and the built environment, has
announced an industry first with the launch of the only Robust
Detail accredited dry-finish acoustic wall construction which also
provides a thermal bypass solution to meet Part L 2010 (Approved
Document L1A, Table 3).
Robust Detail E-WM-20 separating wall construction incorporates
100mm Isover RD Party Wall Roll. It meets the full-fill requirements
for a zero U-value now specified for party walls in Part L1A
Building Regulations when installed correctly and accompanied with
effective edge sealing. In addition, it is the only system of its
kind to offer four credits towards the Code for Sustainable Homes
and offers unrivalled acoustic performance, 8dB above the current 45
dB Part E requirements.
E-WM-20 incorporating Isover RD Party Wall Roll eliminates the need
for pre-completion testing and does not require plaster or parge
coating prior to drylining. In addition, the insulation is supplied
in roll format, minimising vertical joints and providing a practical
solution to give faster installation and more accurate job costing.
RD Party Wall Roll is also approved for use in four additional
Robust Detail party wall constructions incorporating a range of
block types including lightweight aggregate, Plasmor Aglite Ultra
and Aircrete. Constructions incorporating RD Party Wall Roll have
been used on over 3,000 plots to date, offering a tried and tested
solution with which to meet thermal bypass and acoustic performance
requirements.
Stacey Davis, marketing director for Saint-Gobain Isover, comments:
“Until the 2010 Part L revisions it was thought no heat was lost
from attached properties through the party wall, with the assumption
being that it was simply transferred between the two buildings.
However, research has proven that this is not the case with cavities
between the walls providing a chimney effect to result in heat loss.
As a result, the revised Building Regulations have assigned a
notional U-value of 0.5 to party walls
“House builders using Robust Detail constructions incorporating RD
Party Wall Roll to achieve acoustic regulations can now be confident
that these constructions will help to deliver a zero U-value
to meet these Part L 2010 requirements. Saint-Gobain Isover is the
only insulation manufacturer to provide a full-fill dry-finish
thermal bypass solution, providing customers with a time and cost
saving solution to meet their needs.”
Manufactured under a Quality Assurance Scheme in accordance with EN
ISO 19001: 2008 Isover RD Party Wall Roll has a BRE Green Guide A+
Summary Rating and a Euroclass A1 fire rating.
Isover offers a range of high performance insulation products
designed to meet thermal, acoustic and fire safety requirements for
the built environment. The company is committed to continuously
improving the way in which its products and processes impact on the
natural environment and is the only glass mineral wool manufacturer
to achieve the maximum possible recycled content, 86 per cent, using
recycled glass that would otherwise go to landfill.
The company’s market-leading efficiency means less energy is used in
the manufacturing process and the use of Isover insulation helps to
reduce emissions. Products also boast ODP (Ozone Depletion
Potential) and GWP (Global Warming Potential) ratings of zero. Its
three point plan for environmental sustainability ensures that
Isover and its products, in manufacture and when in-situ, use less
materials, less energy and produce less emissions.
