Door systems

Door systems by heroal provide for both barrier-free solutions and zero-barriers. Zero-barriers make the free passage of an entrance element possible. Any limitations, which are often seen with threshold variants necessary to ensure tightness, do not exist. In combination with the drainage system heroal DS, heroal door systems offer flush solutions compliant with statutory regulations according to German industry norms DIN 18040-1 for public places and DIN 18040-2 for barrier-free flats. In addition, full accessibility and protection against moisture damages inside have been combined in one system. Learn more about the drainage system heroal DS now.

Innovative door systems geared to the future require maximum quality, with a minimum usage of materials for manufacture and maximum energy and cost efficiency during the entire service life. heroal profile systems set new 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. Thanks to the unique insulating strip geometry and the 100 % foam filling of the profiles, the best insulation values are achieved. These meet and even exceed the requirements of the current German energy saving regulation (EnEV). The geometries of the insulating strips reduce both energy flow and heat conduction from the inside of the element to the outside.

By a modular design of the insulating zone, heroal provides for U-value adjustments. Large-volume centre sealants (D 92) with multi-chamber technology, vulcanised sealant corners or a complete sealant frame with all-round corner vulcanisation ensure optimal heat insulation up to passive-house suitability. The sealant frames ensure maximum system security due to almost 100% repeat accuracy during production. An integrated element mitring ensures optimal mitre sealing within the area of the sealant frame corners. All heroal sealants are equipped with a sliding polymer coating.

High temperature differences between the inside and the outside may cause deformations of the sash frame. As a result of adding three innovative steps to the production process, heroal profile systems offer effective protection against this negative effect due to thermal expansion (cf. bi-metal). The design of the patented heroal profile composite is characterized by its two-parts composition with a rolled-in insulating strip and slide-in spring. The heroal profile composite has the same mechanical features (statics, splitting force etc.) as standard insulating strips, whether machined or not. The integrated warp reduction does not affect the visual appearance and does not require any additional production effort. It is also possible to retrofit both door frames and sash frames.

heroal offers a new way of fixing the panel to the aluminium profiles of the door. This installation method makes it possible to fix the pre-fabricated panel in the sash via joining. The different heroal panel fixings make the production of maximum sash sizes possible. A new profile design for this way of panel installation has been added to our range of door systems. It makes it easier to install the panel, even on-site, and change the design later on by simply replacing the panel. The processing of these door systems is also time-saving.

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 “green” insulating strip 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.

heroal surface coating opens up design options that could not be realised with other materials. Coating variants for every application are available. 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 effects, 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.
