CEMTEQ ESTABLISHED TO SUPPLY SMART, SUSTAINABLE BUILDING MATERIALS Wadeville-based Sun Silicates has established a sister company, CemteQ Build- ing Solutions (Pty) Ltd, that specialises in developing and marketing unique, value- adding products for the building and construction industries. CemteQ will focus on using high quality Perlite produced by Sun Silicates as an aggregate replacement, together with cement and special admixtures, to produce unique and bespoke solutions for the building and construction industries. Due to the nature of Perlite, these composite products offer significant insulation, lightweight, fire-resistant and acoustic properties. Cemteq will be launching with a construction grade loose Perlite, a value- added plaster composite in white and grey as well as specially formulated, value-added floor and roof screeds. News Watch SunPerl construction-grade loose Perlite will be available in 100 litre polypropylene bags with a bulk density of 70-80kg/m 3 . For the past 70 years, loose Perlite has been widely used in the construction industry in Europe and the USA for its exceptional insulating and lightweight properties. The construction grade Perlite is the same aggregate used in high temperature insulating refractory concretes. Perlite excels in these applications, due to its high melting point, low density and chemically inert nature. PlasterLite is a super- smooth, easy-to-apply composite for trowel- on plaster and low- velocity pumped plaster applications. This is a formulation of exfoliated Perlite with quality cement, various admixtures and micro- fibres in a unique bagged, one-coat plaster solution without the requirement for a skim plaster. The plaster product will be introduced in white and grey and offers significantly better insulation properties than ordinary plaster, saving significantly on heating and cooling costs. The R-value for 15mm ordinary plaster is approximately 0.021m 2 .K/W whereas the R-value for a perlite plaster is 0.043m 2 .K/W, offering significantly better insulation than ordinary plaster. Perlite plasters also weigh 8.4kg/m 2 at 15mm thick on the wall whereas normal plaster weighs in excess of 27kg/m 2 . This reduces the weight of plaster alone by one ton per 54m 2 at 15mm thick. CemteQ has also launched its value- added screed products. ScreedPerl and EcoPerl have been designed for standard lightweight and insulating applications as well as for ultra-lightweight and insulating applications to achieve maximum R-values. They effectively prevent downward heat loss in floors with undertile heating, saving significantly on heating costs. They also provide an ultra-lightweight, insulating solution for roofs, providing suitable run-off and preventing water damage. It is possible to apply the products to flat, uneven or curved surfaces with a suitable bonding agent. All CemteQ’s Perlite- based products offer excellent fire protection. They have low linear expansion characteristics which greatly reduce the development of cracks, ensuring that the temperature of the structure and load bearing members is maintained below the critical point at which weakening or failure is likely to occur. They release no smoke or toxic gas and do not disintegrate or spall when cooled suddenly with a firehose. The products also provide efficient sound dampening, particularly for pulsed sounds, are inorganic and do not rot or decay over time. [email protected] www.cemteq.com 9
