Rockwool ‘Rockfall Systems’
Thermal insulation slabs for pitched roofs
‘Rockfall is the perfect insulation system for warm pitched roof providing an effective insulating of the roof space at rafter level. In a Mansard application, it allows a flat warm roof to be continued through to the pitched roof area. The system is adaptable to almost any pitched roof configuration. Suitable from 15o to the steep pitches.
The system comprises of a high density overlay board mechanically fastened over the rafters with a lighter density underlay slab, placed between the rafters. With a vapour control layer and plasterboard finish to the underside of the rafters, the Rockfall system minimises thermal bridging and external noise pollution through the structure.
Thermal conductivity (K value)
Rockfall Underlay = 0.035W/mK
Rockfall Overlay = 0.038W/mK.’
