Cempanel BUILDING BOARD CEMENT PARTICLE BOARD

Cempanel Class “0” cement particle board with excellent impact, fire and acoustic properties. Its durability, consistently high manufacturing tolerances and lack of need for wet trades makes Cempanel ideal for off-site and modular construction. Cempanel (cement particle board) is superior to timber and plasterboard panel products when used as internal linings on rainscreen cladding projects (sheathing), general purpose external boarding, floors or studwork interior walls. Cempanel is both stronger and less absorbent than timber and plasterboard. The high cement and alkaline content also...

Product Specification Cempanel is an exterior and interior cement particle cladding and lining board that is far superior to timber sheathing. Cempanel does not absorb water and is structurally stronger than timber. Technical Information Specific Properties Standard Board Size Quantities (sheets) per pallet Grey surface with particulate core Length / Width Moisture Content Surface Alkalinity Bending Strength Thermal Conductivity (K Value) Tensile Strength Perpendicular to Plane Dimensional Tolerance Thickness Swelling (Immersed in water 24hrs.) Fire Resistance BS 476 Part 6 and 7....

The strengths of Cempanel Cempanel combines the strength of cement with the flexibility of timber. It is resistant to changes in heat and moisture. This quality makes Cempanel fire resistant and a good thermal insulator. Sound reduction Sound insulation can be improved by using insulation between 2 panels. Board thickness 2 layers of board thickness 48mm x 32mm galvanized steel @ 610mm centres 70mm x 32mm galvanized steel @ 600mm centres faced with 100mm x 24mm strips Thermal insulation Having a 0.125 W/mºC K value makes Cempanel cement particle board popular as a lining in temperature...

Installation & Fixing All fixing holes should be manually drilled with a hole 0.8mm larger than the desired fixing. Fixings Countersunk steel or galvanized self-tapping screws 3.5mm - 4.2mm diameter, 2.5 to 3 times the board thickness. Method – nails screws or staples, manually, pneumatic or power fixed. Site work Cempanel should be cut in the same way as chipboard with tungsten carbide tipped blades at 3000 - 4000 r.p.m. If a highly sanded surface is required e.g. for direct application of paint, conventional hand held wood sanders can be used indoors in conjunction with dust extraction...
