Sliding and lifting-sliding systems

Sliding and lifting-sliding systems by heroal provide for both barrier-free solutions and zero-barriers. A threshold completely integrated in the floor makes 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 lifting and lifting-sliding systems offer flush solutions (zero-barrier) 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.

heroal profile systems for sliding and lifting-sliding doors 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, heroal systems achieve Uw-values meeting the requirements of the current German energy saving regulation (EnEV) without the use of frame or glazing rebate insulations.

heroal aluminium composite profiles are filled with PU-foams. 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 this foam fill process developed by heroal 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 sliding and lifting-sliding door systems yield a better and optimized heat insulation because of the 100% foam fill of the insulating chamber.

The innovative injection of sealants ensures an optimal sealing of mitre joints and T-connections with low material usage. The guided distribution of sealant and innovative connector geometries make an efficient and time-saving manufacture possible. To meet international standards and requirements, corner angles that can be nailed or compressed as well as screwable and clampable corner connectors are available. Optimal heat insulation is ensured by T-connectors equipped with closed-cell foamed rubber used for sealing rebate areas.

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 unmachined. 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 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. 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, 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.
