Spantec recommends sheeting be glued and then screwed down.
Fixing should be done with wing tip steel threaded screws, and then glued with Maxbond, Sikabond, Liquid Nails or an equivalent.
Sheets may be nailed with 2.5mm hardened twist nails, this form of nailing requires around 100psi -note this is not Spantec’s recommended method.
