Doncaster Lakeside Stadium
The 15,000 capacity Lakeside Stadium complex is a £28 million project initiated by Doncaster City Council and is due for completion in December 2006. After that, the sports stadium will be home to Doncaster Rovers FC, Doncaster Belles FC and the newly renamed Doncaster Lakers RLFC.
The entire stadium project needed to comply with Part L2 of the latest building regulations regarding thermal and acoustic insulation and fire retardation. As well as sealing in crowd noise and providing fire protection for large areas of the terraces, spectators also needed to be protected from isolated cold spots occurring at the venue.
The stadium’s architects, Carillion needed impartial insulation advice, as well as a broad range of options regarding suitable products.
Knauf Insulation’s on-site advisor was able to draw up a complete product specification for the stadium as a whole. To tackle both the cold spot problem and to reduce noise, Knauf Insulation supplied 317m2 of Polyfoam Floorboard Standard and Polyfoam Floorboard Extra and this was installed throughout the stadium. Polyfoam Floorboard is a high performance, versatile XPS rigid board, suitable for floor, wall and roof applications. Although lightweight, it is extremely strong, thermally efficient and moisture resistant.
A total of 2500m2 of Crown DriTherm 85mm was supplied for use in the cavity walls, which is a massive 70 per cent of the total stadium area. Crown DriTherm is a rigid slab of glass mineral wool with a water-repellent additive. It is dimensioned to fit between wall ties at standard spacings and is ideal for the thermal insulation of masonry cavity external walls, either partially filling or fully filling the cavity.
For insulation and fire protection of large areas under the terraces, Knauf Insulation worked with its sister company, Knauf Drywall. A specification was reached featuring 40mm of Rocksilk Universal Slab RS60 and100mm of Rocksilk Universal Slab RS33. This is an unfaced rock mineral wool, multi-purpose slab for use in a variety of applications. Rocksilk Universal Slab operates to Euroclass A1 fire standard and can be used up to continuous operating temperatures of 850°C.
