Fixing
Details
- The system is suitable for traditional timber rafter, timber trussed rafter and rigid sarking constructions. The system is designed to fit a straight and level ridge line with equal pitches on either side of the ridge.
- When used with traditional timber rafters, the height of the ridge board above the apex of the rafters will alter the height of the ridge batten required.
- Ensure the ridge tile securing screw achieves a minimum 15 mm of penetration.
- Where timber sarking is used with the system, sarking is left short of apex to allow 10mm air gap, underlay is cut and turned up between counterbattens and fixed to top tiling battens. Counterbattens are extended to form an apex to support the ridge tree batten.
- A special pack (9396) is required when using Ornamental Universal Angle Ridge Tiles.
- Where Gas Flue Ridge Terminals are used with the system, Gas Flue Conversion Packs should be used. One pack per Terminal.
- Counterbattens/rafters on adjacent roof slopes must be aligned.
