Steel Frame - 4.2mm x 42mm self-drilling and self-countersinking, wingtip.
Timber Frame - 4.2mm x 42mm self-drilling and self-countersinking.
Step 1. Application accordance:
Cembloc CemPlate is suitable for Timber Frame, Lightweight Steel Frame and Modular/ Offsite. In most cases battens at 600mm centres is suitable although if the building is exposed to higher wind load or exposure, we would recommend vertical battens fixed at 400mm centres . The board is designed to be installed by a competent builder, or a contractor, experienced with this type of product. A suitably qualified and experienced individual must check the design and method of installation of the boards.
Step 2. Cut boards to size:
Cut Cembloc CemPlate using a circular saw fixed with a suitable vacuum extractor and a Polycrystalline Diamond (PCD) Saw blade to avoid excessive wear on other blade types. This method will cut boards easily at the same time mitigating dust. Our Cembloc boards can be cut with either a fine tooth hand saw or power saw, whilst ensuring suitable dust control measures are taken (eg localised extraction where possible, protective safety glasses, gloves and respiratory masks as per MSDS) and observing all necessary health and safety regulations. Boards should be fixed with the board text facing upwards (smooth texture).
When cutting panels around a passage or door, note that the joints must not be aligned with the edge scale of the door or the centre of the opening. We find that most render manufacturers recommend using either a window, but boards should be single or double layer cut of render around mesh over the opening and fixed on to a the key stress points such as minimum 25x60mm batten corners of the The boards must be supported by a minimum of a 25x60mm batten all the way around the opening to ensure a stable support to render on opening.
Step 3. Fixing:
Unlike traditional timber frame, SIP panels do not include an internal stud but the outer OSB layer is typically structural enough to fix the render carrier system (aka our CemPlate) directly to it. Like any timber frame, the frame will require a breather membrane, followed by the battens vertically at either 400mm or 600mm centres (as stated in Step 1), then proceed as you would in a standard timber frame build up. Typical fixing detail of render is: Cembloc Cemplate, Render Base coat, Render Mesh, Render Base Coat, Prime followed by render finish coat.
Step 4. Mechanically fix with screws:
Screws should be a minimum of 12mm from board edges and spaced at a maximum of 300mm. The screws must not be over-tightened. 27 Nr. fixings per 2400x1200mm sheet when fixed in a horizontal orientation or 28 Nr. fixings per 2400x1200mm sheet when fixed in a horizontal or vertical orientation.
