Eaves purlins side laps to be stitched at 500 mm centers between purlins all in accordance with manufacturers recommendations

Fastening
Trimflute IBR is pierce-fixed to timber or steel supports. This means that fastener screws pass through the sheeting. You can place screws for Trimflute IBR through the crests or in the valleys. To maximise water tightness, always place roof screws through the crest. For walling, you may use either crest or valley fixing. Always ndrive the screws perpendicular to the sheeting, and in the centre of the corrugation or rib. Don’t place fasteners less than 25 mm from the ends of sheets.

The edge of the Trimflute IBR with the anti-capillary groove is always the under-lap. It is generally considered good practice to use fasteners along side-laps however, when cladding is supported as indicated in purling spacings, side-lap fasteners are not usually needed for strength.

End-laps are not usually necessary because Trimflute is available in long lengths. If you want endlaps, seek advice from your nearest Safintra office on the sequence of laying and the amount of overlap. When Trimflute is laid on slopes of 7.5 degrees or more, cut back the corner of the undersheet, at the downhill end of the sheet to block capillary action.
