8 Ywall is a flexible cement/calcium building board, for applications that require a slightly lighter board with improved fire properties. One of our core objectives when formulating Y-wall was ensuring maximum workability on site. The lighter composition of the product allows easier use on site, offering both full sheets 2400mm x 1200mm as well as 1200mm x 1200mm as standard. With manual handling becoming an ever greater consideration on projects, products such as Y-wall are leading the way in applicator consideration. The product offers very similar properties to that of cement particle board, but due to the calcium additives, it has much greater fire resistance properties. This is to meet the ever more stringent demand from specifiers, clients and insurers in the market place. Basic Composition Ywall is manufactured from a mixture of cement, lime, calcium silicate and other additives. General Properties Ywall is resistant to the general effects of moisture, humidity changes, rot, insects, vermin and has excellent fire related properties. Machine-ability Ywall can be drilled, sanded and worked in similar fashion to that of cement particle board, or fibre cement board. Contact for supply of recommended cutting blade.

16 Building Technologies / Assessed Renderflex & Render Typical Metal Frame Makeup Typical Timber Frame Makeup Base Coat Base Coat The growth in render applied directly onto building boards has been significant over the past few years This type of system provides significant cost benefits, faster build times, and potentially a reduced external footprint. As with any significant benefit however, there can be other potential risks. The biggest risk with this type of solution, is ensuring the board and for that matter the renders are compatible and fit for purpose. Renderflex has been specially formulated and developed for this very application. Key issues such as Mechanical fixing strength Freeze thaw performance Modulus of Rupture and Elasticity Bond strength between board and renders Wind loading with render Polymer and acrylic render to board reaction tests This is a short list of just some of the third party accredited UK testing which has been carried out on Renderflex and associated render finishes. understand the properties and characteristics of the polymer and acrylic renders, and have combined this knowledge with our expertise in cementicious board technology, to provide tried and tested product, which meets the specific demand of the market place. 15

30 Storage Always stack boards on a smooth flat surface clear of the ground. Boards must never be stored on edge or upright. Protect edges from chipping. Loose storage of boards on their edges is not recommended. If boards need to be stacked, always ensure blocks properly align. Store boards in dry conditions and under cover, fully protected from the weather and other trades at all times. Cover boards to keep dry prior to fixing. If sheets do become wet, allow to dry thoroughly prior to fixing. Handling When handling individual boards from stack, slide sideways and lift by spread arms on long edges to give even support and prevent excessive flexing of the board. Do not drag sheets off the stack. Protection gloves and footwear are recommended when moving boards. Boards are heavy; ensure H & SE guidelines are followed. Cutting Use of a fine tooth hand saw or a power saw is recommended. Contact for supply of recommended cutting blade. Support both ends of the board when cutting to avoid breakaway. When drilling, cutting or sanding cement manufactured products, wear safety glasses and approved dust mask or respirator. During clean up, contain dust by vacuum or wet down methods. Safe disposal also requires containment of dust. Long term exposure to dust can be harmful to health. All suitable health and safety issues should be implemented. 29
