58 Warm roof with Mineral Wool installed to EURIMA best practice 1. Tiles x 38 battens x 50 battens 4. Vapour permeable underlay taut, joints lapped & sealed w / tape x centres mm mineral wool (0.035W/mK) 7. Air & VCL, joints lapped and sealed w / tape 8. 50mm mineral wool (0.035W/mK) between 50 x 50 battens perpendicular to the rafters mm plasterboard
