Aluminium - the material with a future Through its 12years long experience with aluminium, especially with commercial buildings such as offices, plants, warehouses, etc. and also with public buildings, we has developed an outstanding level of expertise. In such scenarios, requirements regarding durability, the retention of value in the long term and easy maintenance are a major part of the investment calculation. Previous received opinion, namely that aluminium had weak thermal insulation properties and was prone to condensation problems has long since been refuted. Thanks to thermal breaking of aluminium profiles by means of PVC-U insulating bars, aluminium systems are every bit as good as systems using other materials. With a Ufvalue (heat transition coefficient of the window) of 1.4, the AWS 75.SI (SI = Super Insulation) system achieves the same thermal insulation values as PVC-U and timber. Security Likewise with regard to security, aluminium also offers the best possibilities to protect your belongings. From fittings with a higher resistance class against burglary to bullet and blast-resistant systems and fire protection, there are many ways in which excellent security standards can be achieved, in combination with the corresponding fittings system and the glass. Convenience Apart from being smooth in operation by design, aluminium windows are especially convenient and comfortable when electrically operated. Xinshan TipTronic represents a world first in this field and operates in a similar way to central locking on cars, combined with electrically operated windows. Design A particular point in favour of aluminium is its appearance: especially in the case of large formats, its high static values allow narrow profiles to ensure maximum daylight. External and internal surfaces may be finished in contrasting colours, so that for example a facade that appears flamboyant from the outside can use reserved, neutral colours within. In addition, the concealed AvanTec fitting looks great due to its uncluttered design, achieved through concealed hinges on the edge of the window.
