The rockwool twin roll insulation delivers high-performance thermal and acoustic insulation engineered to prevent heat loss through roofs and floors. Manufactured from 97% recycled materials, this solution combines exceptional energy efficiency with environmental responsibility. Designed for pitched roofs and suspended timber floors, the perforated roll allows precise cutting to fit 400mm or 600mm timber joist centres. Installation flexibility accommodates either a single 200mm layer over joists or two 100mm layers between them, adapting to specific project requirements. Lightweight construction ensures straightforward handling and installation while maintaining resistance to mould and bacteria growth. The non-reactive formulation remains safe alongside pvc cables, pipes and metal components, offering zero ozone depletion rating and zero global warming potential.
