Pitched roof

The thermal efficiency of UNISPAN MW roof panels from UNILIN, along with their ability to minimise material consumption in the roof structure and to provide a fast-track building method, makes them the ideal solution for healthcare and other public sector buildings.

Specified by KLH Architects at an early stage to ensure the most efficient construction, approximately 2,000m2 of UNISPAN MW structural sandwich panels now provide an airtight and rigid roofing structure that meets the stringent requirements for sound insulation and fire ratings for large public buildings.

UNISPAN MW panels are available in different thicknesses to comply with Building Regulations Part L requirements. The mineral wool insulation is held between four rafters, which are stabilised by a ceiling board and upper board. The panels are available in lengths of up to eight-metres, ensuring the most efficient use of materials on the large roof areas of public sector buildings. The design of the PICU at Hellesdon Hospital involved both pitch and flat roofs and UNISPAN MW sandwich panels were used throughout.

Installed by Barnes Construction Limited, UNISPAN MW panels can be installed at rates of up to 500m2 per day, enabling fast-track construction and providing a weather-tight structure that helps to reduce overall construction times.

"The thermal performance of UNISPAN MW, along with all our structural insulated roof panels, means they are ideal for all buildings looking to reduce energy consumption and hence their impact on the environment," comments UNILIN, division insulation.

"The adaptability of structural insulated roof panels, their ability to reduce materials used in building construction and the fast track construction that they provide, make them particularly suitable for public sector buildings such as the Rollesby Ward, PICU at Hellesdon Hospital", concludes UNILIN.

UNISPAN MW roof panels | UNILIN Insulation

  • A sandwich panel incorporating mineral wool insulation (minimum 35kg/m3) suitable for pitched or flat roofs.
  • Panels are rigid and meet stringent requirements for sound insulation, fire ratings and large spans (BBA certificate applied for) and are ideal for all buildings from domestic to large public buildings.
  • The ecological benefits of the panels can be further enhanced by the inclusion of timber insulation (density 40kg/m3) made from natural timber fibres. The panels can be installed either. horizontally or following the slope of the roof onto structural wall, structural timber trusses/purlins or steel purlins.
  • Sandwich panels can be supplied with ends cut to an angle at ridges and/or eaves level. Infill panels on request.
  • On flat roofs, UNISPAN MW can be finished externally with a range of different roof coverings including bitumen, standing seam, EPDM, PVC, etc.
  • The thickness of the upper board must comply with the roof covering supplier’s fixing requirements and with the relevant Building Regulations. Where the roof is subjected to high humidity (Climate Class IV and in swimming pools) please contact UNILIN for product feasibility.
