Every building project is unique and has its own technical challenges.

Pitched roofs can be covered with a wide variety of materials. Clay tiles such as flat sliding tiles, plain tiles, interlocking tiles or hollow tiles are very popular. The 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 well suited to the use of solar energy in the form of thermal or photovoltaic systems.

The lighting and shading concept can be very versatile. Roof windows from VELUX or ROTO or entire rooflights can be installed. The appearance, design and use can vary.

Manual or electric roof hatches with ladders or stairs can be installed for access to roof terraces, flat roofs and various other conditions.

Flat roofs are increasingly becoming adventure and recreation zones. Due to high-density construction, flat roofs with their usable terraces and roof gardens are becoming increasingly popular and in demand. The requirements for this type of roof have risen sharply. The waterproofing is made of bituminous, multi-layered waterproofing membranes, plastic membranes or rubber membranes. We use liquid plastic for complex connections to doors and other connections. The use of flat roofs is very diverse today. The usable surface can be covered with gravel, concrete slabs of various shapes and colors, natural stone slabs or coatings. Wooden decking made from native or exotic woods is also very popular.  In order to maintain a pleasant living climate in the city and especially in one's own recreation area, roof surfaces are greened. Green roofs can be used extensively or intensively. Extensive green roofs are roofs with low vegetation. Intensively used roofs are true roof gardens with shrubs, flowers and even trees. Both uses also promote nature conservation, especially the insect world. Flat roofs are also used to harness solar energy.

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

When constructing the building envelope, it is important to comply with building regulations and the physical requirements of the building. The individual layers of the building envelope - paneling/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 create a comfortable living environment. Noise pollution is particularly high in cities. This can be almost completely absorbed by the right choice of materials.

The increasing use of cell phones means that the mobile phone network is being expanded further and further, which also increases the radiation exposure from transmitters and receivers. We can provide you with expert advice and suggested solutions, especially when it comes to radiation protection in the low-frequency range.

We also offer you the execution of various tinsmith works. Correctly dimensioned roof drainage in the form of gutters, downpipes, valleys and drains reduces the potential for damage enormously. The craftsmanship of the tinsmith is particularly in demand in the old town. The old historic buildings have a great deal of roof decoration in the form of gargoyles, decorations on the skylights, ... which often need to be recreated. But modern architecture with its filigree lines also makes demands on the tinsmith's trade.

Lightning protection systems are installed to protect a building or a mobile phone antenna from lightning strikes. We plan and implement lightning protection systems right through to handover to the local lightning protection supervisor.

We carry out the interior work, the cladding of walls and ceilings, as well as the construction of floor structures with plasterboard from the manufacturers Knauf, Rigibs and Fermacell. Great attention must be paid to fire protection requirements. The correct structure must be selected depending on the use of the floor surfaces. Unevenness in the substrate can be evened out or underfloor heating elements can be installed in the structure. The individual components can also be clad directly with wood. There are many possibilities

Every building also needs maintenance. That's why we offer you maintenance for your building depending on how much it is used. The maintenance contract can be customized. It is important to check the roof covering and the proper functioning of the drainage system
