48 INSULATION
Kershaw Insulation Rises to the Challenge with Tower Block Insulation
the London Borough of Hillingdon. Following surveys of the tower blocks it was decided by Hillingdon London Borough Council to undertake additional fire safety. Kershaw Insulation was approached to review
K
the feasibility of installing insulation into the partially filled cavity. Following a site meeting and survey it was discovered that the cavity was only 40mm, meaning that the insulation supplier initially selected was not an option as the insulation could only be used in cavities of 50mm or more. As the works involved improving fire safety
for the residents, Kershaw Insulation had a keen interest in helping to find a solution. Working closely with Hillingdon London Borough Council and the main contractors, Quinn London, Kershaw Insulation looked to provide an alternative solution for the high-rise towers. Due to their strong relationships within
the market, Kershaw were able to approach Knauf Insulation to establish what materials they had for filling partial cavities at 40mm. After a second site meeting, Knauf Insulation's
ershaw Insulation are delighted to have successfully completed retro-fit insulation works on four tower blocks in
Technical Support Team (TST) decided that an appropriate solution would be to use their Supafil CarbonPlus. The product is a high performance, non-combustible, blown Glass Mineral Wool specifically designed for installation into existing masonry cavity walls with narrow cavities down to 40mm. Happy with the alternative product, Kershaw
Insulation was appointed by Quinn London to carry out the works. Knauf Insulation's Supafil CarbonPlus was used to fill the remaining cavity between the original Styrofoam insulation and the external brick cladding. This eliminated any remaining air space
which could possibly fuel a fire if it were to occur. This additional insulation will also make the tower blocks more energy efficient and therefore help to reduce the residents CO² emissions and future fuel bills. The works were carried out to all four blocks over a period of fewer than 8 weeks, which included an allowance for making good the site, pointing all drill holes in the brickwork and leaving the site in a clean and tidy state. In addition to the retrofit insulation works,
Kershaw also provides services for new-build developments and can carry-out thermal
imaging surveys as an effective method of identifying if there are any hidden defects within a building.
