Sapphire - Modular roof tile - panel

Wooden grid:

• It is recommended to use battens with a minimum cross-section of 40×50 mm (depending on the rafter spacing).
• To construct the supporting structure, use:wooden battens with a cross-section of 40 x 50 mm or 40 x 60 mm,wooden counter-battens with a cross-section of 40 x 50 mm or 40 x 60 mm.
• To create the sub-structure for the roof covering assembly, use dry construction wood of at least C24 or KVH class, impregnated with agents that do not cause corrosion of coated steel sheets.
• Particular attention should be paid to the batten spacing measured from the same edges, which depends on the type of covering, as well as the even line of their assembly and the leveling of their plane.
• The wooden batten sub-structure should guarantee a level and stable plane for the roof covering assembly! Counter-battens are used to fix the roof membrane (underlayment – FWK) to the rafters. Roof tile panels are fixed directly to the battens. The sub-structure prepared for the roof tile assembly should have a level plane and right angles of the roof slope.
• Before spacing the battens, the module length must be measured. Remember that the measured module length follows the scheme below.

TIGRA Plus assembly:

• Due to its asymmetrical shape and the applied capillary groove solution, TIGRA PLUS panel roof tile requires a traditional assembly method.
• The capillary groove construction with side drainage in the TIGRA PLUS roof tile is an additional innovative protection that effectively drains rainwater on every roof tile module.
• The applied solution and the asymmetrical shape of the roof tile profile require the contractor to follow the correct sequence of joining sheets by overlapping the covering rib onto the underlapping one (with the capillary groove) when assembling from right to left. Assembly from left to right, as well as from the bottom to the top of the slope and in the opposite direction, is also permitted. Remember to maintain the correct sequence of sheets in accordance with the rainwater flow direction.
• Remember to use self-drilling 4.8 x 20 mm stitcher screws for joining sheets and 4.8 x 35 mm assembly screws.
