Premium performance products from Kingspan Insulation have been used to insulate new high and low rise buildings as part of one of London’s largest and most ambitious regeneration programmes.
Woodberry Down was once heralded as the ‘estate of the future’ but in recent years had suffered from an increasing number of issues including: subsidence, asbestos, damp, and poor insulation. An eight phase regeneration plan will replace outdated concrete tower blocks with more than 5,500 brand new homes over the next 20 years. Architect Hawkins\Brown specified Kingspan Kooltherm K12 Framing Board and K15 Rainscreen Board for Kick Start Sites 2 and 5 within the master plan, comprising 710 residential units and over 1500 m2 of commercial space, spread across a number of blocks.
Kingspan Kooltherm K15 Rainscreen Board
was installed as part of the anodized rainscreen cladding used on the top storeys of many of the blocks. These sections extend beyond 18 metres and it was, therefore, essential that the product offered excellent fire performance. The board has been tested to BS 8414-1 and BS 8414-2, and successfully assessed in accordance performance criteria set out in BR 135, in a range of insulation thicknesses with a variety of cladding finishes. It is, therefore, acceptable for use above 18 metres in accordance with the Building Regulations / Standards in its tested configurations.
Kingspan Kooltherm K12 Framing Board
was also installed within a steel framing system behind the main brickwork façade elements. The lightweight boards are easy to install and can be used with timber or steel frame constructions. Both products deliver premium levels of thermal performance, with thermal conductivities as low as 0.020 W/m.K and have been assigned 2008 Green Guide Summary Ratings of A+ by the BRE.
The Woodberry Down regeneration is an ambitious project - the result of a collaborative partnership between Berkeley Homes, Hackney Council, Genesis Housing Association and the residents’ group, Woodberry Down Community Organisation. Once completed it will include three new public parks; a community centre and library; a children’s centre; and retail and commercial opportunities.
