Meet the highest requirements on design for commercial and residential buildings with aluminium window systems and at the same time achieve best insulation values up to passive house certification and protection against burglary up to resistance class RC 3.

Window systems

Window systems for special projects, commercial and residential construction

Special is our standard. With heroal aluminium window systems, you can not only reach passive house certification and passive house suitability with a design depth of only 77 mm, but also burglary protection up to resistance class RC 3. All windows are sustainably produced, certified by the German testing institute ift Rosenheim and offer highest quality combined with maximum energy and cost efficiency – „Made in Germany“. Thanks to the material aluminium, heroal window systems have a very long service life and require only minimal maintenance. Window systems made by heroal have been installed in the most diverse buildings across Europe, among them the Elithis tower in Strasbourg, the first Plus-Energy-tower, and V Tower in Prague, considered one of the most exclusive high-rises in the Czech Republic.

Product characteristics of heroal window systems

  • Insulating strip technology

    Insulating strip technology

    heroal profile systems for windows set standards when it comes to heat insulation, sustainability and efficiency. A unique insulating strip geometry is at the core of the development, combining maximum load with lowest loss of heat. The innovative geometry of the insulating strips reduces both energy flow and heat conduction.

    Thanks to this unique strip geometry, the heroal window system W 72, for example, meets the requirements of the current German energy saving regulation (EnEV), with a frame design depth of 72 mm and a sash design depth of 84 mm (Uw=0.84 W/m2K) and no additional frame or glazing rebate insulations.

  • Foam fill process

    Foam fill process

    heroal aluminium composite profiles are filled with PU-foams in a particular process developed by heroal. 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. The advantage of heroal’s own foam fill process is the complete filling of the sealing zone. As opposed to the so-called “backpack” variants, where the insulating material is glued on the insulating strips, heroal window systems yield a better and optimized heat insulation because of the 100% foam fill of the insulating chamber.

  • Profile technology

    Profile technology

    On the basis of QM 323, a certification scheme by the German testing institute ift Rosenheim, heroal is the only manufacturer of thermal break aluminium/PVC composite profiles within a manufacturing network subject to external monitoring. The perfectly tuned combination of adhesive cord and knurling in the heroal insulating process ensures above-average rigidity and increased strength of heroal aluminium composite profiles.

  • Sealing technology

    Sealing technology

    By a modular design of the insulating zone, heroal provides for U-value adjustments. Both high-insulating (HI) and standard variants are available for different heat insulation requirements. Large-volume centre sealants with multi-chamber technology ensure optimal heat insulation. This is achieved through vulcanised sealant corners or through a complete sealant frame with all-round corner vulcanisation. The sealant frames ensure maximum system security due to almost 100% repeat accuracy during production. All heroal sealants are equipped with a sliding polymer coating.

  • Ecological project solutions

    Ecological project solutions

    Sustainability in the manufacture of aluminium composite profiles is an important indicator for the quality of heroal system technology. 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.

    The insulating strip used for heroal W 72 consists of 62 % renewable resources. Compared to usual strips of identical quality, heroal saves 20 % of non-renewable resources. Castor oil gained from the seeds of castor beans is the basis for sebacic acid, which, in turn, serves as a basis for renewable resources.

    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.

    Sustainability >
  • Surface coating

    Surface coating

    A variety of colours and durability in all kinds of environmental conditions are the central factors when choosing a suitable surface coating. The coating technologies developed by heroal open up a variety of design options. For example, heroal’s high-quality hwr powder coating provides refined surfaces in different first-class gloss rates and coating qualities. In addition, heroal partners have exclusive access to the 63 Le Corbusier colours. The innovative surface coating heroal SD creates even more exciting looks, such as wood or concrete. All coating technologies are characterized by the typical heroal quality and support the durability of the various heroal systems.

  • Special solutions

    Special solutions

    The different design elements of heroal aluminium window systems, such as alu semi-facings or cover profiles, can be individually designed, meeting the architectural demands of planners and architects. Because unique architecture needs tailor-made solutions. The system features of the standard series still apply without any limitation. Conclusively, optimal solutions for almost every need can be created by heroal systems.
