Cladding System Details

This unique cladding system is made up of pieces of natural slate or stone, that are hand picked and mounted onto reinforced concrete backed 'Z' shaped panels. Sperrin cladding system comes in two main formats, one for straight walls with separate corner panels and the other the universal panel, which can be used for straight runs and also inward and outward corners.

Please Note : Update - Almost all our stone types now come solely in the universal panel format.

Panel Structure
Format 1: Wall Panel

Wall Panel Pack

Each box contains 4 panels of size

600x200x30/40mm and covers 0.44M²

To calculate the quantity you require, first multiply the height by the length and add 10% for cutting and wastage.

Format 2: Corner Panel

Corner Panel Pack

Each box contains 4 panels

 2 @ 600x200x30/40mm and

2 @ 315x200x30/40mm

Each box will cover 0.33M² &

two courses of a corner (0.4M)

To calculate the quantity you require, measure the height of each corner and add, then divide by 0.4M, to give you boxes needed.

Multipy boxes by 0.33M² and minus the result off the wall panel total, to give correct area for wall panels.

Format 3: Universal Panel

Universal Panel Pack

Each box contains 5 panels

3 @ 600x200x30/40mm

1 @ 365x200x30/40mm

1 @ 265x200x30/40mm

Each box will cover 0.456M²

Every panel can be used for either wall or corner

Fitting Instructions

Sperrin Clad can be installed both internally and externally. For all applications it is critical that the surface onto which the cladding is to be applied has the strength and stability to hold the product.

Sperrin Clad with a weight in excess of 65kg/M² can not be fixed directly onto gypsum based products, plasterboard, plyboard or painted surfaces, in these instances a cement based board or 18mm plyboard with expanded metal attached should be fixed to the wall.

It is important that your first course of cladding is level, it will be harder to correct errors later. Use packing pieces to level if necessary. Using a notched trowel, adhesive should be applied to both the panel and the surface they are being applied to, then simply push the panel firmly onto the wall with a slight up and down movement, use a rubber mallet if required. Corners on each course should be completed first, it is vital to use the long cornered piece on the bottom row and then alternate between courses with the short corner piece as you move up the wall. Complete the corners at either end of the course before working to the centre, were panels need to be cut using a electric grinder or a table saw in a 'z' shape to maintain a seamless pattern. For panels fitted above 2 metres, it is recommended the use of a stainless steel fixing clip, that is fixed to the wall.
