New school sets high standards with EcoTherm
A new slant on a school roofing
solution fromGradient
A project to refurbish an original 1960s flat roof on a Derbyshire school has underlined the high level of flexibility and expertise provided by Gradient Flat Roofing. Derbyshire County Council asked Gradient to design a new insulation layer
which would eliminate the existing valleys and backfalls and allow the entire roof to drain effectively. After a detailed examination of the roof, Gradient proposed a combination of cork underlay board and PIR insulation to remedy the situation. Bespoke pieces of tapered insulation would be used to level off the backfalls and create an even roof surface, before a further layer of tapered insulation was then added to create positive falls across the roof and allow rainwater to run off to a series of newly created drainage points. The resulting roof would also provide thermal insulation which exceeded Building Regulation requirements. The 23-week project was completed with the application of a 3-ply built- up mineral felt surface layer over the Gradient insulation.

Offering outstanding thermal efficiency and green credentials, EcoTherm polyisocyanurate (PIR) boards are providing a sustainable insulation solution for the roof, walls and floors of the new Sandal Magna Junior and Infants School in Wakefield, West Yorkshire. The use of EcoTherm PIR insulation is helping the green school building project to exceed thermal efficiency standards under current Building Regulations by at least 10%. In fact, a U- value of 0.13 W/m2K - that is 35% better than Building Regulations - has been projected for one of the roof constructions incorporating 100mm EcoTherm Pitched-Roof insulation board.

Derby College, The Roundhouse Campus, Derby
The Roundhouse Campus development at Derby College was part of an imaginative £43m regeneration scheme which was undertaken to provide around 18,000m2 of learning and teaching space. Combining the transformation of derelict buildings dating back to 1839 with additional new build premises, the project involved installing 11,500m2 of soft floor coverings and 600m2 of ceramic wall and floor coverings, all with Mapei products. In the annex building, Domus Ecotech large format tiles were installed on the prepared
substrate. Made from recycled porcelain, these tiles combine sustainability with aesthetic properties and high performance and were installed using Mapei’s fast setting adhesive, Keraquick mixed with Latex Plus additive which meant the surface was ready for light foot traffic within 2-3 hours. In the toilets and wash areas, 250m2 of glazed ceramic wall tiles were installed using
Mapei’s MapeGrip D1 and MapeGrip D2 high performance adhesives which are ideal for use in commercial wet areas. The floors were finished with vitrified unglazed slip resistant tiles. The carriage shop listed building proved to be more complex.
The existing floor was a mix of old timber and concrete which required extensive preparation to create a level, durable floor. The concrete slabs were prepared using Mapeproof ESM and Latexplan Trade. A 1000 gauge waterproof membrane was laid and then covered by an 18mm layer of plywood. This surface was then primed and screeded over with Mapei’s ultra-fast hardening self levelling compound Fiberplan. Then the floor was ready for the vinyl sheeting and Flotex HD sheet floor covering. The project overall was highly complex with a wide range of
different products used to create the new campus. Completed on time, the college opened its doors to students in Autumn 2009 as scheduled and English Heritage has recognised this project as one of the top ten conservation schemes in the country.
