Installation

Installation sequence

  1. Fix a 60mm thick timber stop batten across the rafters at eaves (A).
  2. Lay ROOFMATE™ RL-X  boards with long edges at right angles to the rafters and with the tongue pointing up the slope (B).
  3. Butt the first row of boards tight against the stop batten. Continue laying up the slope towards the ridge.  At ridge butt ROOFMATE RL-X to the ridge board (B) or to ROOFMATE RL-X on the opposite slope. (C).
  4. Fix ROOFMATE-RL-X boards temporarily by occasional nailing until permanently secured by the counter battens.
  5. At all cut edges, junctions and penetrations trim ROOFMATE RL-X boards neatly to fit (D) (E). Seal any gaps with polyurethane foam.
  6. Either: (a) lay the underlay directly onto the ROOFMATE RL-X boards and secure with counter battens; or (b) secure the ROOFMATE RL-X boards with counter battens, then drape the underlay over the counter battens and secure with tiling/slating battens. (Refer to underlay supplier’s instructions).
  7. Fit ROOFMATE RL-X boards cut-to-size between the rafters from within the loft space. Press tight against the ROOFMATE RL-X boards and fix by nailing support battens to the rafters (F).
