Every building project is unique and has its challenges in terms of craftsmanship.

Pitched roofs can be covered with a wide variety of materials. Very popular are clay tiles such as flat sliding tiles, plain tiles, interlocking tiles or trough tiles. Roof surfaces can also be covered with a wide variety of natural slates or Eternit tiles. Metal roofing such as copper, chrome steel or Uginox is also very popular. Pitched roofs are very suitable for the use of solar energy in the form of thermal or photovoltaic systems.

The lighting and shading concept can be very versatile. Roof windows of VELUX or ROTO or whole light bands can be installed. The appearance, design and use can be different.

For access to roof terraces, flat roofs and various other conditions, manual or electric roof exits with ladders or stairs can be installed.

Flat roofs are increasingly becoming experience and recreation zones. Flat roofs with their usable terraces and roof gardens are becoming more and more popular and in demand due to the densified construction. The requirements for this type of roof have risen sharply. The waterproofing is made of bituminous, multi-layer waterproofing membranes, plastic membranes or rubber membranes. We perform complex connections to doors and other connections with liquid plastic. The use of the flat roof today is very diverse. The usable surface can be only gravelled, coverings can be made of concrete slabs of various shapes and colors, natural stone slabs or of coatings. Wooden coverings made of native or exotic woods are also very popular. In order to maintain a pleasant living climate in the city and especially in one's own recreation zone, roof surfaces are greened. Green roofs can be used extensively, but also intensively. Extensively greened roofs are roofs with low vegetation. Intensively used roofs are true roof gardens with shrubs, flowers, and even tree growth. Both uses also promote nature conservation, especially insect life. Flat roofs are also used for the exploitation of solar energy.

The design of the building facades can be very different. We specialize in the rear-ventilated design with a wide variety of substructures and claddings made of natural slate, Eternit slate/fiber cement panels or metal.

During the execution of the building envelope superstructures it is necessary to pay attention to the building regulations and to the building physics requirements. The individual layers of the building envelope - wainscot/ fibreboard, vapour barrier, supporting structure, thermal insulation, sub-roof, rear ventilation, roofing, ... must be coordinated with each other. This is the only way to avoid structural damage and to create a comfortable living climate. Noise pollution is particularly high in cities. This can be almost absorbed by the right choice of materials.

Due to the increasing use of cell phones, the cell phone network is being expanded more and more and thus the radiation exposure from the transmitters and receivers is also increasing. Especially for steel protection in the low-frequency range, we can provide you with competent advice and propose solutions.

We also offer the execution of various tinsmith works. A correctly dimensioned roof drainage in the form of gutters, drain pipes, flashings and drains reduce the damage potential enormously. Especially in the old town the craftsmanship of the tinsmith is required. The old historic buildings have a lot of roof decoration, in the form of gargoyles, ornaments on the hatchways, ... which should often be recreated in this way. But also the modern architecture with its filigree lines demands the tinsmith's craft.

In order to protect a building or a mobile phone antenna from lightning strikes, lightning protection systems are installed. We plan and execute lightning protection systems until the handover to the local lightning protection supervisor.

We carry out the interior finishing, the covering of walls and ceilings, as well as the construction of floor structures with Gibskarton boards of the manufacturers Knauf, Rigibs and Fermacell. Great attention must be paid to the fire safety requirements. Depending on the use of the floor surfaces, it is necessary to choose the right structure. It is possible to level out unevenness in the subfloor, or to install floor heating elements in the structure. The individual components can also be directly covered with wood. There are many options

Every building needs care. Therefore, we offer you the maintenance of your building, depending on the demand. The maintenance contract can be arranged individually. It is important to check the roofing and the proper functioning of the drainage system.
