APPROVAL FOR NEW PART L - 7.10.10
Knauf Insulation welcomes the
revisions to Part L of the Building Regulations and Section 6 of
Scotland’s Building Standards, which aim to reduce CO2 emissions
across-the-board by an additional 25percent and 30percent in
Scotland compared to current standards.
Of particular interest is the recognition that there is
significant heat loss through unfilled cavities in separating walls
between attached dwellings. The new versions will come into
force this October requiring any new build party walls to be fully
filled with an insulation material that has been shown to limit air
movement and have effective edge sealing, in order to achieve an
effective U-value of zero.
Stephen Wise, Technical Development Manager at Knauf Insulation
states: “Mineral wool insulation is particularly suitable for this
application as independent tests undertaken by the School of the
Built Environment at Leeds Metropolitan University showed that the
effect of full fill mineral wool insulation was to eliminate the
party wall thermal bypass, when combined with the installation of
simple sleeved mineral wool cavity barriers to provide edge
sealing. Importantly, on site testing showed that the acoustic
performance of the walls is also maintained after filling with
mineral wool.”
“The revisions to Part L and Section 6 are substantial in the
drive towards the Government’s zero carbon goal and Knauf
Insulation supports this by developing and furthering our own
energy efficient building materials and solutions.”
