GDRR Dry Fix Roll-Out Ridge

None.

GDRR-BS Batten Support Bracket.

Guidance for specification option:

• Material: Galvanized steel.
• The Manthorpe Batten Support Bracket provides a steady, secure platform for the horizontal ridge batten at the apex of the rafters, when fitting the Manthorpe Dry Ridge system.
• The brackets have four different bend points to accommodate a range of roof pitches and tile heights and are designed to hold a single length of 25 x 38 mm batten.

GDRR-RR Vent Roll.

Guidance for specification option:

• Supplied in lengths of 6 m, the Ridge Roll is placed along the length of the ridge prior to the ridge tiles being installed.
• The roll is made up of a vapour permeable membrane down the centre, with a corrugated acrylic coated aluminium strip down each edge.
• The malleability of the aluminium allows the roll to be shaped to the profile of the roof tiles and is secured in place with a butyl strip already attached to the underside.
• The punched vapour permeable membrane will provide ventilation to the roof void of 5000 mm²/m whilst avoiding the ingress of wind driven rain and the entry of large insects.

GDRR-RU Ridge Union.

Guidance for specification option:

• Material: Polypropylene.
• The Ridge Union sits in the gaps between each of the ridge tiles, holding them in place.
• The ridge union body slides onto the end of the ridge tile and is flexible so that it bends to the shape of the tile.
