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 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.
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.
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.
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.
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.
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.
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.
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.
An intelligent combination of geometry and material enables the new heroal W 77 window system to achieve a Uf value of 0.95W/m²K (view width: 120 mm) at passive-house level, with an installation depth of just 77 mm. With this development, heroal has designed the thermally separated aluminium window in such a way that it not only meets present demands stated by the 2016 German Energy Savings Regulation (Energieeinsparverordnung, EnEV) over the long term, but also fulfils future requirements for “nearly zero-energy buildings”.
The innovative system solution for the latest generation of sustainable, aluminium windows
Innovative, future-oriented window systems demand the highest quality with minimal energy and material consumption during manufacture and maximum efficiency for energy and costs throughout the lifetime of a product. To ensure the unique level of heroal quality, it has always been our policy to carry out the key production steps in our own factories, applying our own expertise. heroal has developed an innovative system solution for durable aluminium windows in line with this guiding principle, which is setting new standards – heroal W 72.
The heroal W 72 CW window system offers planners individual, object-oriented design options for window elements between floors. Large openings and spaces can thus be realised as a classic mullion and transom design.
