Meta-SlatePlus is a roofing sheet that has the appearance of natural slate but embodies the advantages of a modern lightweight but strong building material. Meta-SlatePlus is manufactured from 0.7mm galvanised coil with a slate blue matt polyester paint finish to the outer surface and a grey epoxy based primer to the inside. The sheet is specially embossed with a regular slate pattern and finished to appear like natural slate. Other external colours and finishes are available by special order subject to quantity and coil availability. Meta-SlatePlus is ideal for use in environmentally sensitive locations where box profile sheeting may not be acceptable to local authority planning departments. Meta-SlatePlus is extremely easy to fit and boasts a beautifully simple secret fix joint system. Meta-SlatePlus roofing sheets are available in lengths up to 6m.

The AS35 insulated panel consists of two coated steel profiles bonded to a core of PIR insulation. The metal sheets are made from either Z275 galvanised steel or AZ150 aluminium-zinc coated steel to BS EN 10326:2004. The top profile is 0.5mm thick, and the internal liner 0.4mm thick, and are both covered by a choice of one of several organic coatings. Panels are available in lengths of 1.8m to 12m and in thicknesses of 40, 60, 80 and 100mm.

Meta-SlatePlus is designed to provide a strong, rigid slate effect roof with good thermal performance down to a 10° pitch. The system includes a comprehensive range of clips, jointing pieces, flashings, end closures, sealants and coated steel or plastic gutters and downpipes.

The Meta-SlatePlus system offers rapid coverage and swift completion of a weatherproof building envelope to give a high performance building. To download a pdf of the Meta-SlatePlus overview brochure, click here.

Fixing Meta-Slate roofing sheet over an AS35 insulated roofing panel
Once the AS35 has been securely fixed to the roof substructure in accordance with the Certificate holder’s instructions, the Meta-Slate roof sheets can be fixed in place.

The installation of the Meta-Slate roof sheets over the AS35 panels is very similar to the installation over rafter/purlins. The roof sheets are fixed every third raised section of the AS35 panel using 5.5mm by 25mm self-drilling screws. The screws are fixed through the overlap between panels so that the screw is driven through two thicknesses of the metal top sheet (fixed at a maximum of one per metre of panel length). The frequency of fixing can be increased around the edges of the installation or where special detailing is required.
