Building Better Days Cembrit companies have been manufacturing corrugated sheets since 1910. With nearly a century of production in fibre cement roofing and cladding, we are able to draw on experience of installation across the whole of Europe. Incorporating the latest technological advances, the fully accredited system of sheets allows designers to clad equestrian or sectional buildings in a Class A2 fire rated, rust and rot-proof material that has been in our built environment for decades and is available, ex-stock, in the UK. Manufactured using Portland cement, together with a...

B5 Corrugated Sheet B5 Fibre-cement corrugated sheet is a replacement for the standard 3 inch profile corrugated sheet. Coloured top coat Primer coat Coated edges Anti-block on underside Coloured edges and ends The B5 metric corrugation profile is a more modern profile than the traditional 3 inch profile so can be used to a lower pitch and with smaller overlaps. The sheets are approximately 40% wider, offering a better coverage per sheet. B5 is available in 11 lengths from 4' 6" to 10'. B5 can be used to refurbish buildings clad in 3 inch sheets utilising ‘existing purlin centres’. All...

Design Specifications Mitring scheme To avoid having 4 layers of overlapping roof sheets, the corners of two sheets must be mitred. Each mitre must be cut straight and cleanly either by hand or by power saw. The angle and size of mitre is governed by the end and side lap dimensions. It is recommended that a good quality butyl mastic strip is used to seal the overlapping sheets to provide a weatherproof join. Two corners of opposing sheets should be mitred the equivalent of the head and side lap (i.e. maximum 110mm x 150mm) with a gap between sheets of 3 – 6mm. Sheets on the perimeter of the...

Pre-drilling (Every sheet should be twice fixed at each purlin) It is extremely important that the correct roof purlins/rail system, type of fixing and washers are selected, to eliminate leakage/corrosion and the general deterioration of the construction. It is recommended that a self-drilling Top-Fix screw is adopted. This simple method offers a fast, low-cost fixing solution. Using a high-speed screw gun, drive in the fixing. The fixing system is only suitable for roofs up to and including 30˚ pitch. Using a tungsten carbide tipped drill at 90˚ angle to the sheet, drill a hole 2mm larger...
