7.2.11 Support for equipment
Permanent equipment in roof voids shall be adequately supported.
Where equipment (eg water tanks and MVHR fan units) is located in the roof void, the structure should be designed in accordance with PD 6693-1 and the truss manufacturer’s recommendations, to support the additional load. Platforms supporting permanent equipment, should be positioned with a minimum clearance of 50 mm between the top of the insulation and the underside of the platform, to ensure a clear ventilation space.
