Curtain wall systems

Innovative profile systems geared to the future require maximum quality, with a minimum usage of energy and materials for manufacture and maximum energy and cost efficiency during the entire service life. heroal’s insulator technology provides for optimal positioning of screws during curtain wall manufacture; it makes different insulating variants possible and at the same time minimizes inventories. All individual insulating components of the system have a standard design and can be used in almost all heroal curtain wall systems.

heroal aluminium composite profiles are filled with PU-foams in their modular sealing zone. The insulating foam is produced without the use of halogenated propellants such as HCFC. The natural resources sugar and starch serve as additional stabilisation agents. As opposed to the so-called “backpack” variants, where the insulating material is glued on the insulating strips, heroal profile systems yield a better and optimized heat insulation because of the 100% foam fill of the insulating chamber.

The sealing of heroal curtain wall systems towards the structural system meets highest system security standards and is very efficient because of simplified planning and processing. Functions such as curtain wall ventilation and drainage are combined at the base point and that way reduce the number of building parts. Any additional processing of the post profiles is unnecessary. The sealing system makes an easy transition to rainscreen cladded areas possible (ventilated – non-ventilated façade). The uninterrupted, all around installation of the base profile and well-defined integration of foils both inside and outside ensure a vapour-tight connection towards the structural system and the floor.

Post-transom connection:

Transoms are put into the rebates of the posts and fixed by different connectors. That way, a particularly sturdy construction is built.

Post-transom special connection:

For sloped, polygonal curtain walls or curtain walls that require removable transoms.

Post-post connection:

The posts are connected by butt joints. Especially suited for optimising cuttings.

Transom-transom connection:

The transoms are connected by butt joints. Especially suited for small curtain wall panels or infills.

heroal pays special attention to the sustainable and certified manufacture of aluminium composite profiles. The smart material usage starts with the manufacture of the profile semi-facings. Following the closed loop aluminium recycling principle A|U|F, recovered materials are returned to the production cycle. Eco-friendly production is also a priority when it comes to profile coating. Excessive powder quantities are collected and re-used in a state-of-the-art powder coating facility. Hence, both fabricators and partners also benefit from heroal’s commitment to sustainability.

heroal surface coating opens up design options that could not be realised with other materials and offers coating variants for every application. Above all, the focus is on design and colour variety as well as surface coating durability. heroal coating technologies offer numerous options for design. Different gloss rates and surface designs, such as concrete or wood, are available. The close cooperation with Les Couleurs® Le Corbusier gives heroal access to an exclusive, harmonious range of colours. All surface coatings are characterized by the typical heroal quality and support the long lifespan of heroal systems.
