EL ALUMINIO Y SU ALTA EFICIENCIA TERMICA

Aluminium in The Building and Construction Industries – Aluminium Frames Provide High Thermal Efficiency


Background
Aluminium is a product with unique properties, making it a natural partner for the building industry. Thanks to its strength, durability, corrosion resistance and recyclability, it has become an essential product for the building industry and over the past 50 years its use in building applications has shown continuous and consistent growth.
Applications of Aluminium in Construction and Building
Aluminium extruded, rolled, and cast products are commonly used for window frames and other glazed structures ranging from shop fronts to large roof superstructures for shopping centres and stadiums; for roofing, siding, and curtain walling, as well as for cast door handles, catches for windows, staircases, heating and air-conditioning systems. Most recently, aluminium has played a significant role in the renovation of historic buildings. The characteristics and properties of aluminium as a material have lead to revolutionary and innovative changes in building techniques and architectural and engineering projects. Aluminium is leading the way into the future of the construction industry.
Thermal Performance
Whether used on its own, in the form of foil on heat insulation products, or laminated on to other base materials, aluminium construction industry products contribute substantially to the energy efficiency, quality and safety of houses and buildings.
Aluminium Frames with High Thermal Efficiency
Like most metals and alloys, aluminium conducts heat easily. However, in applications such as window frames, especially extrusion designs and thermal breaks are used to produce highly thermally efficient frames. For example, modern aluminium window frame members are assembled from three components: an inner and an outer frame, between which is sandwiched a central core of material selected to offer strength, long term stability and excellent thermal insulation properties. The central core therefore minimises the heat transmission that might otherwise occur due to aluminium’s natural thermal conduction properties, thereby avoiding energy loss or condensation.

No estoy de acuerdo, hoy en día el PVC tiene prestaciónes mucho mas altos que aluminio.
