Lightweight pre-fabricated elements are applied on the facade walls of a building for decorative purposes. Cornices, floor markers, window frames and modillion brackets are made according to specific designs using polystyrene foam coated with weather resistant materials that provide a plaster effect. The light weight of the polystyrene foam makes installation quick and easy even in the most difficult situations. The coating materials in concrete-and-resin-based plaster provide a perfectly weather resistant layer. Arbloc supplies the shock resistance data needed to establish the level of resistance to...

Note: some minute creeks msy sppesr after the installation, which however do not reduce the quality of the product over time and can effectively be filled and sealed with an elastomeric coating. FEATURES | Polystyrene foam core. | Polyurethane resin and marble granules/dust based finish. Series 2006 lightweight pre-fabricated elements are made with modem products and techniques. They have a core made of polystyrene foam, cut according to design and a coating in compact, stiff polyurethane resin with added marble granules. This product can satisfy the widest range of demands in terms of form and...

USERS MUST KNOW THE FEATURES OF A LIGHTWEIGHT PRE-FABRICATED ELEMENT IN ORDER TD INSTALL IT PROPERLY. THERMAL EXPANSION The thermal expansion of polystyrene foam is higher than stone-like materials usually used in construction. The X coefficient ranges from 5 ■ 1CT5 - 7 ■ IQ5. Compared to concrete (X = 1.2 ■ IQ5], polystyrene's thermal expansion is 4 to 6 times higher. Variations can reach 1.5 mm per 1 m in length with a 30°C thermal increase. Hence each installation must be evaluated carefully especially in terms of support, glues, and mechanical anchors. SUPPORT A key element for successful...

INTRODUCTION Installing a lightweight pre-fabricated element requires proper fixing. Otherwise thermal expansions among different materials may, over time, lead to cracks on the joins, detachments from the wall or crevices on the surface. The thermal expansion of polystyrene foam is higher than stone-like materials. Not bearing this aspect in mind might jeopardize the final result. Each installation must be evaluated carefully especially in terms of support, glues, and mechanical anchors. Big cornices - such as under-roof and under-gutter ones - present increased difficulty due to their larger...

METHOD 2 MOUNTING WITH SUPPORTING TIMBERING The pre-fabricated element is fixed on the timbering and laid against polystyrene elements that avoid overturning. The prefabricated elements are custom-made and delivered with already cut and joined comers. If requested, we can provide a drawing that shows how to place the elements. EXECUTION PHASES FINISHING In the last phase of construction the polyurethanic foam is injected in the joins to glued them together. We suggest to do this in winter months, when lower temperatures reduce reduction of the polystyrene. The join is concealed with a fiberglass...

Example A To install floor markers, apply the cement glue on the entire surface of the pre-fabricated element and use anchors to press the lightweight pre-fabricated element against the wall during the first few hours before the adhesive holds firmly. When the floor marker is glued directly on the plaster (example A] check this has good consistency. An insufficient plaster can lead to detachment following thermal expansion. We recommend you always use a special adhesive for walls. When external insulation is applied we recommend you glue the pre-fabricated element directly to the wall (example...

Today, the most widespread system for creating cornices is the use of polystyrene molds. Premium concrete surface, appropriate amount of cover for metal reinforcements to suit environment conditions, less joins, and glued corners are just some of the quality features of these molds. Moreover, our Topform polystyrene molds are custom-made and coated in order to satisfy builders' needs and provide customized carpentry solutions. Topform ensures trouble-free installation, high resistance, quick and easy removal, plus less labor costs and more money saving without compromising the quality that has always...
