Specifying External Timber Frame Walls
About Saint-Gobain Isover
As a world leader in designing, manufacturing and
distributing building materials, Saint-Gobain is committed
to providing innovative solutions to the most fundamental
challenges facing the world today; reducing energy
consumption, limiting our impact on the environment
and creating a new generation of buildings which are safe,
comfortable and energy efficient.
At Saint-Gobain Isover we develop sustainable insulation
solutions to protect both your built environment and
the natural environment. To maintain our focus we have
placed environmental responsibility at the heart of our
business strategy.
Saint-Gobain: one of the top
100 Industrial groups in the
world and the global leaders
in the construction market.
Our vision to lead the UK mineral wool market in energy
efficiency and acoustic insulation solutions will be
achieved with products that meet the highest thermal,
acoustic and fire safety performance levels. We will
meet changing regulations first and surpass current
regulations for those that wish to excel. Our products
will provide best value solutions for the residential,
commercial, RMI and technical building environments,
be safe to use and help to protect the environment.
Between 15 and 18% of all new homes in the UK are
now timber frame. Popularity of this construction
method has grown over recent years due to speed of
construction and better quality control on-site. For
that reason, ensuring these constructions are energy
efficient is vital if we are to achieve the commitment of
the Climate Change Act to eliminate carbon emissions
from our built environment by 2050.
Between 15 and 18 percent of
all new homes in the UK are
now timber frame.
At Saint-Gobain Isover we are committed to working
jointly with today’s designers and contractors to meet
these challenges, in making buildings of the future as
energy efficient as possible.

The
Solutions providing insulation for three key aspects of the built
environment. The inherent properties of Isover products provide thermal,
acoustic and fire safe insulation for external timber frame walls.
Thermal
Quick and easy on-site
installation
Isover offer energy efficient thermal
solutions to meet and exceed even the most
demanding requirements.
• Push fits between 600mm timber stud
centres with no need for additional fixings
• Isover insulation is manufactured from
high quality glass mineral wool which
makes it lightweight and easy to handle,
cut and install
Acoustic
Isover’s solutions provide a comfortable living
environment, protecting inhabitants from
exterior noise such as road traffic, trains and
aeroplanes.
Environmental leadership
Isover timber frame insulation has excellent
environmental credentials and helps
towards valuable credits for the Code for
Sustainable Homes.
Fire & Safety
Isover insulation is totally non-combustible
and fire safe to protect your most precious
resource and provide a safer building
environment.
• Recycled content of up to 86%
• Zero Ozone Depletion Potential (ODP)
• Global Warming Potential (GWP) of less
than 5
Water resistant
Isover timber frame cavity wall insulation
is resilient to moisture damage in storage,
during transportation and on site during
installation.

Building regulations & standards
Approved Document L (1A and 2A) 2013
Approved Document L (1A and 2A) 2013 retains the design element of fabric elemental backstops, however it is not
recommended that these are used as the starting point for building design. Achieving the Target for Fabric Energy
Efficiency (TFEE) standard could be significantly dependent on the high performance of one specific feature of fabric
design. If this feature was to perform less well than expected, it would significantly impact on performance. These
are designated as limited design values to discourage inappropriate trade-offs (e.g. poor elemental U-values being
offset by renewables etc.)
As absolute backstop values, the fabric elemental values that remain unchanged from Approved Document L:2010
can be seen in the table below:
External Walls
Limiting fabric parameter (W/m2K)
New Build – Residential
0.30
New Build – Non-Residential
0.35
Section 6 – Scotland 2010
The standards and guidance given in Section 6 2010 are intended to reduce emissions of carbon dioxide by
approximately 30% compared to the 2007 standards. The key changes over the 2007 version are:
• 30% improvement in CO2 emissions for new buildings
• Expanded role for the use of low carbon equipment
• Improved backstops for fabric U-values and service efficiencies for new buildings
Section 6 includes a range of measures which can be used in setting the target emission rate for a notional dwelling.
Included are guideline “notional” U-values, as follows:
External Walls

The Code for Sustainable Homes
Passivhaus Trust
Isover products can be specified to achieve reduced
CO2 target emission rates by means of insulation for
improved U-values. Specialist products such as the
Isover Vario Membrane System and expert design
guidance can also help to achieve improved airtightness
performance. For more information or to request a CPD,
call 0115 969 8010.
Isover is a founding member of the Passivhaus Trust.
The Passivhaus Trust is an independent non-profit
organisation that will provide leadership in the UK for the
adoption of the Passivhaus standard and methodology.
Its aim is to promote the principles of Passivhaus as a
highly effective way of reducing energy use and carbon
emissions from buildings in the UK.

UK Timber Frame Association
Isover is a member of the UKTFA, working with the
association and its members to highlight the benefits
of timber frame construction and promote best practice
within the industry.

Product overview
Isover Vario Membrane System Isover Cavity Barriers
A high performance membrane unique in providing
excellent levels of airtightness with unparalleled
protection against moisture.
A non-combustible glass wool cavity barrier used to
restrict the spread of smoke and flames and to minimise
flanking noise transmission in concealed cavities.
3Improves the energy efficiency of the building by
reducing heat loss
3Improves thermal comfort by protecting against
leaky cracks and joints which invariably cause
uncomfortable drafts
3Ideal for use in low energy and Passivhaus
constructions and buildings with mechanical
ventilation and heat recovery systems
3Intelligent moisture management properties help
to protect the building fabric from moisture damage
3Provides up to 100 minutes fire protection
in concealed cavities which helps to meet
requirements of Approved Document B (England &
Wales) and Section 2 (Scotland)
3Helps minimise flanking sound transmission along
the wall cavity
3Helps towards a zero U-value separating
wall by providing effective edge sealing¹
