1 isocem s/b NON AUTOCLAVED STRUCTURAL CELLULAR CONCRETE...the action of the man, in harmony with nature... isocem s/b isocem s/b IS A TECHNOLOGY DEVELOPPED AND PRODUCED BY NON-AUTOCLAVED CELLULAR CONCRETE BLOCKS: ISOCEM S/B

2 isocem s/b NON AUTOCLAVED STRUCTURAL CELLULAR CONCRETE THE TECHNOLOGY ISOLTECH HAS CREATED THE MOST ECO-FRIENDLY, VERSATILE AND ECONOMIC SYSTEM TO PRODUCE BLOCKS Isoltech building system in non autoclaved cellular concrete is the most complete and ecofriendly building system available nowadays. It doesn t require ovens or autoclaves, non autoclaved cellular concrete uses very few energy to be produced, and it makes a limited use of natural resources. 1. Isoltech building system can work with a total of 10,6 kw installed for 5 minutes, to produce 1 m3 of material. 2. Cellular concrete is similar to wood. As this one can be cut and nailed, even if with special nails or nogs. It has the same specific gravity of wood and it is insulator also. 3. The versatility of the production systems allows moving them easily. Thanks to their cost effectiveness and compact size, the systems needed to produce Isoltech blocks can be installed anywhere near target markets (even in the right-sized construction sites), reducing to a minimum transport costs (compared to the significant costs for all traditional materials). 4. The versatility is also in the dimension of the block: the mould developed by Isoltech permits to produce different dimensions of blocks, to be used in dividing walls and eternal. 2

3 Isoltech building system ENERGY SAVING STARTS IN PRODUCTION The necessary energy for the production is one the most important requirements requested to an eco-friendly material. And, below this aspect, cellular concrete has no equal. The Energy Return On Energy Investment (EnROEI), the most efficient use of Energy is the value which marks Isoltech technology from all the other alternatives. To produce building materials, it is extremely important to use as few natural resources as possible and especially to save fossil fuels. A comparison with similar products usually available on the market gives an outstanding result for Isoltech blocks and leaves no doubts about their superiority, both for the energy consumption to produce them and for the use of eco-friendly materials (cement, sand, water and protein hydrolysed).

This is because the energy for the curing is provided by the heat from the hydration of cement, properly recycled with special technical devices. 3

4 isocem s/b NON AUTOCLAVED STRUCTURAL CELLULAR CONCRETE THE MATERIAL NON-AUTOCLAVED CELLULAR CONCRETE ENERGY SAVING BEFORE AND AFTER THE CONSTRUCTION ISOLTECH technology is a building technology and not a specific material. Different possible materials can be used. Although previously selected and evaluated by Isoltech laboratory, the final mechanical characteristics are strongly influenced by the original raw materials. The data listed here are so conservative and indicative and can be easily improved. Isoltech, for its part, has an enviable experience, to get from raw materials provided, the best possible performance. MECHANICAL RESISTANCE Isoltech non-autoclaved cellular concrete blocks fulfill the requirements of mechanical resistance. The table below shows the already excellent mechanical strength, further improved by the Isoltech sophisticated technology, which uses where appropriate, special systems mixing and peculiar incremental additives of mechanical strength, specifically formulated.

5 Isoltech building system EXCELLENT HEAT AND SOUND INSULATION PROVIDES BETTER COMFORT THERMAL INSULATION The Italian legislative decree of 29/12/2006, transposition of the Directive 2002/91/EC on energy performance, introduces the concept of integrated calculation of the energy performances of buildings. In particular, the following requirements must be met: 1. The calculation of the energy performance index for winter conditioning (EP) and the testing of conformance with the values reported in Annex C, point The transmittance values of the vertical, horizontal and tilted opaque components (all types of building) that surround the building shall not exceed by over 30% the values reported in the table mentioned in the points 2, 3, 4 of Annex C. If the radiation =>290 W/m2 on the horizontal plane (except Zone F and categories E6 and E8), the surface mass of the vertical, horizontal and tilted opaque walls must be higher than 230 kg/m2. The following table reports the energy classification in Italy, divided into 6 zones (for vertical opaque components) and the U values of blocks with different thicknesses. With a density of 600 kg/m3, Isoltech solution already exceeds the requirements of the energy consumption regulation in force from The energy certification of buildings has a section for the heat insulation class and another for the quality of energy-efficient systems. Therefore it provides the buyer with information about the energy performance and the degree of efficiency of houses and other buildings, and it increases the market value of the property. Since July 1st, 2009 every building must have a Certificate of energy efficiency and comply with the regulations for the area it belongs to. From the table below, we draw the elements to see the formidable thermal performance of cellular concrete. In addition, the high thermal inertia due to the considerable mass gives comfortable living even in structures in warm places for the favorable moving of the heat from 10 to 16 hours.

6 isocem s/b NON AUTOCLAVED STRUCTURAL CELLULAR CONCRETE THE MATERIAL EXCELLENT HEAT AND SOUND INSULATION PROVIDES BETTER COMFORT SOUND INSULATION MICROCLIMATE AND ENVIRONMENTAL COMPATIBILITY Cellular concrete offers extraordinary sound absorption. Buildings made with blocks of cellular concrete meet legal requirements regarding sound insulation. Blocks for partitioning or infilling (40x20x20) have particular sound insulation properties. With a much higher density (800/1200 kg/m3) when heat insulation is not needed their sound insulation improves. During maintenance, cellular concrete does not release toxic substances and its environmental compatibility is second only to that of wood. As a comparison, the coefficient of environmental compatibility of cellular concrete is 2; that of wood is 1, that of bricks is 10 and that of blocks of expanded clay is 20. Cellular concrete helps to create a microclimate (like in a wooden house). The resulting energy savings create a reduction of heating and air conditioning costs of up to 30%.

7 Isoltech building system ISOCEM S/B ECO-FRIENDLY BLOCKS Blocks of Isoltech building system can be produced in the following dimensions. Length Height Width 400/500/ /500/ /500/ These dimensions can be realized with just one mould, with variable dimensions. Perforated blocks for vertical structures with the following dimensions: Length Height Width 400/500/ /500/ /500/ /500/ /500/ NB: More the block is bigger, more you amortize the cost of the mould. The cheapest configuration is that of a single, larger block size, such as 60x20x45. Length Height Width 400/500/ /500/ /500/ /500/ /500/ To improve the handling of blocks, particularly bulky, we have introduced handles. Also special pieces are available: All blocks must be walled with glue with a thin thickness, made from a special adhesive ACRI 105 mixed with cement, sand and water in proper proportions. The walls have to be plastered with plaster applied with a specific sequence required by ISOLTECH. The plaster will be prepared by mixing cement, sand, water and ACRI 105. The plaster will be applied in two layers with the net ACRIVER. All walls, internal and external, partitions and infill blocks should be finished with the treatment described above.
