Flexi

Rockwool multipurpose Flexi

A part of the Rockwool SoundPro range, Rockwool ‘Flexi’ is a unique insulation product with a patented flexible edge along one side. This unique Flexi edge is produced using patented technology to ensure a perfect fit is maintained between the product and its supporting framework. This ensures the insulation’s integrity. Flexi is designed for a host of applications where perfect fitting insulation is essential; in walls, partitions, floors and roofs. The ‘Flexi’ edge allows the product to be tightly fitted between timber and metal frames, without the need for cutting or waste.

Installing Flexi between rafters

  • Measure depth and spacing between existing rafters.
  • Fit Rockwool Flexi between rafters ensuring a 50mm clear ventilated path is maintained between the roofing felt and insulation.
  • Install a vapour control layer (vcl) min 250 gauge, below the insulation stapled to the
    underside of therafters, ensuring all joints are lapped and sealed.
  • Finish with 12.5mm gypsum plasterboard.

 

Note! In order to accomodate additional insulation, existing rafters may be extended by screw fixing battens to the underside
Note! For the warm roof construction (table 2 on u values page) items 3 and 4 should be omitted
