School roofing today requires a collaborative approach, robust specification and cost efficient product selection. SIG Design & Technology and SIG Insulation are working with the Interserve Kajima consortium on a batch of seven secondary school projects to deliver a value-engineered, robust school roofing solution as part of the Hertfordshire, Luton and Reading Priority (HLR) School Building Programme. School Roofing – Seven More Value Engineered Projects
Four of the schools, including Stopsley High School in Luton, have been designed by London architects, Rock Townsend.
The roofing solution for all seven projects needed to use a tried and tested system to overcome a number of specific design challenges based on three core challenges:
  1. Waterproofing of a mixture of concrete deck and steel deck substrates;
  2. Coping with ongoing foot traffic and maintenance of M&E plant, and
  3. Meeting the stringent acoustic performance requirements of BB93.

SIG and IKO Plc, our manufacturer partner, engaged at very early stage to provide technical liaison between Interserve and the project architect to develop the correct technical and most cost-effective waterproofing solution based on the two elements of a robust detailed specification and a simplified roof design. This early intervention also meant that the roofing team could use the roof design support the challenging thermal compliance requirements of each project.

Stopsley High School
The roofs at Stopsley High School were all installed by Briggs Amasco in an approximate 16 week programme. The largest roof measures 2500m2 and was selected for an inverted roof build-up using IKO’s PermaTEC Hot Melt with Dow’s X-Energy XPS insulation. The two lower, smaller roofs measure 1,200m2 in total and these comprise steel deck insulated with Rockwool’s Hardrock Multifix Insulation and waterproofed using IKO’s PreVENT Torch on Felt System.
As SIG Design & Technology is product agnostic, it was able to select the optimum mix of products needed for an integrated solution. Strong collaboration between SIG businesses continues to support smooth project development and total design support is provided to sub-contractors. Monthly site visits during installation ensure compliance to the specification and reduce the risk of future issues.
The HLR roofing project follows SIG Design & Technology’s unique ‘8 Steps’ protocol, from product selection and design expertise right through to full guarantees and planned maintenance. All products were sourced from SIG as Supply Chain partner to Interserve. The four schools are due to be completed in October 2016.
SIG Design & Technology takes the risk out of roof design, offering a genuinely independent choice of waterproofing for flat, green, zinc and copper roofs. Designs are covered by our PI insurance and we’re part of SIG plc, a FTSE250 company.
