HTO Härtetechnik

About the object

In 2006, the success story of HTO Härtetechnik began with two converted industrial halls. Today, 16 plants operate in five production halls. The area was almost quadrupled in the process.

Today, administration and social rooms alone take up as much space as the entire company did back then. Of course, these rooms have different requirements in terms of lighting and ventilation through windows and doors.

The service provider for machine and mould construction has remained loyal to its location despite the growth – also because extensions and conversions have been carried out within the existing building.

Naturally lit and ventilated office buildings and commercial halls

The typical steel halls lend themselves statically to the retrofitting of windows, arcade rooflights and doors – the façade does not take on a load-bearing function. This flexibility opens up great potential – provided that the right contractor can be found.

The managing director of HTO Härtetechnik, Michael Rauer, makes full use of the great scope for design in the installation of metal windows. He knows that only precision and the highest standards are the basis for success.

Light, air and good mood desired

The customers’ wishes were correspondingly:

  • Visual enhancement of the buildings through façade and window design
  • High-quality windows and doors
  • Combination of movable sashes and fixed glazing, manually and electronically controlled
  • High thermal insulation standards
  • Solar control glazing for office buildings

Individually manufactured hall windows from the professional

In Baier, the expert for metal finishing found the right partner: as an expert for high-quality metal windows and doors, Baier develops and manufactures its solutions exactly according to customer requirements. In doing so, functional and design challenges are solved as well as qualitative standards are set.
Baier manufactured, developed and installed a total of 23 window elements for the administration building and the production halls. Since very few of them are identical, virtually every window and door element is custom-made.

Differentiated window design for commercial halls

The diversity is expressed above all in the dimensions and formats: from smaller 1-2-piece elements to large 4-piece elements as horizontal or vertical light bands. Baier visually differentiated the windows and buildings by using different colour coatings: the frames for the office building are blue (RAL 5002), for the production halls black (RAL 9005).

But the variety is not only for design purposes. The many variants can guarantee that every room and every industrial hall receives the best possible lighting and ventilation. For just about every element, Baier combined fixed glazing with turn-and-tilt sashes – in two cases also an integrated door as an access or balcony door.

High building physics and construction standards for all windows

Baier made no distinctions – and no compromises – in the qualitative standards of all window elements. The thermally separated aluminium profiles in combination with double insulating glazing offers an optimal price-performance ratio.

Also cost-conscious – and good for the environmental balance: Baier used solar control glazing for the windows in the office building. It absorbs part of the sun’s rays, thus reducing the excessive heating of the rooms and eliminating the need for an energetically and financially expensive air conditioning system.

Baier’s service: Individual metal windows and doors for every building task

Similar to HTO Härtungstechnik, Baier sees itself not only as a metal processing company, but also as a service provider. The service promise: the best possible aluminium windows and doors for the respective object – visually and functionally customised, always of high quality.
