HELUZ FAMILY 3in1 load-bearing lintel with integrated but removable thermal insulation is designed for single-layer HELUZ FAMILY thermal insulation brickwork with the best performance on the market. And it has several benefits. These are better thermal insulation properties (an advantage in winter), the lintel meets fire standards and of course adheres to the uniform modular system of the rough construction of HELUZ cut bricks. Its internal space with insulator is very variable for the placement of external blinds and shutters - or, thirdly, it can remain factory-filled with insulator. Thus, a single type of load-bearing lintel can be applied to the house without the builder having to make up his mind in advance whether he wants to install screening or not. The HELUZ FAMILY 3in1 load-bearing lintel is fully concealed under the plaster, is adapted for electric operation and can be installed for taller windows up to 2.5 m, i.e. even for balcony doors.
"The HELUZ FAMILY 3in1 load-bearing lintel is delivered to the building fully equipped with an insulator, no one has to do anything with it, it can be fitted, walled up and you get the load-bearing capacity and thermal insulation properties as if the builder had used classic 23.8 load-bearing lintels. However, at any time he can decide to install a shading system and this lintel allows him to do so thanks to the possibility of gradually pulling out the individual pieces of the insulator, thus gradually giving the builder space for a blind, a small roller blind or even a large box for a roller blind. Thus, at each stage, the maximum amount of insulator for the given solution remains in the translation," explains Filip Bosák, HELUZ Technical Consulting Manager, the benefits of the innovation.
The HELUZ FAMILY 3in1 load-bearing lintel is an important element for contemporary low-energy or passive buildings, as it allows for a free and additional choice of shading systems from different manufacturers. In summer, the shading prevents overheating of interiors, in winter, on the contrary, heat leaks outside, which of course has a significant impact on the energy performance of buildings. This is also why outdoor shading was included in the New Green Savings subsidy programme.

In 2020 HELUZ introduced the second generation of the HELUZ FAMILY 3in1 load-bearing overlay with integrated but removable thermal insulation. The internal space with the insulator is variable for the placement of external blinds, shutters, screens or can remain factory-filled with the insulator.
Thus, a single type of load-bearing lintel can be applied to the exterior masonry of the house without the builder having to think in advance whether or not to install shading. In cooperation with the shading technology suppliers, the polystyrene pull-out segments have also been optimised for more convenient installation of the shading technology.
It provides thermal and acoustic comfort, has a solid concrete part and does not weaken the masonry. It is durable (made of concrete, ceramic and thermal insulation) and allows easy access for installation and maintenance of the shading technology. In doing so, it is hidden under the plaster and not visible in the façade. By gradually removing only some of the insulation from the space, maximum thermal insulation remains for the chosen shading option.
It is used to incorporate shading technology that prevents overheating of the interior in summer and heat leakage in winter => saves energy for heating or air conditioning.
The "u", i.e. the values of the heat transfer coefficient, do not only apply to the masonry, but must be met by the entire structure of the house and especially the windows, the main route for winter leakage or summer penetration of heat energy. Large glass surfaces are a trend in modern architecture, so from the point of view of thermal comfort, it is important to remember the external shading, which should not interfere with the clean lines of the house. HELUZ therefore started years ago to produce roller shutter and louvre lintels to house the boxes of external roller shutters and louvres, which prevent overheating of the houses, the lintels are completely hidden under the plaster.
Designed for single-layer HELUZ FAMILY/ FAMILY 2in1 thermal insulation brickwork.
The technology of single-layer masonry construction made of baked bricks must be taken into account from the very first planning stage of the project, so that all the principles of correct design - designing in module, observing the required clearances of building openings and room clearances - are simply observed.
