ROOF SYSTEMS
We offer flat roofs systems with a slope that does not exceed 2°, and pitched roofs with a slope of up to about 15 °, on which only sheet metal covering is used. There are several different systems of flat roofs. The roof structure depends on several factors, such as the type of substructure (concrete or steel), type of thermal insulation (rock wool, Styrodur or polystyrene) and others.
As part of the roof system installation, we also provide:
- The installation of a water drainage system,
- The installation of lightning conductors and snow guards,
- The mounting of all the necessary tinsmith finishes,
- The sealing of all installation holes and sky domes.
FLAT ROOF SYSTEM WITH A CONRETE SUBSTRUCTURE (CONCRETE GRIDERS)
The first and most frequently used roof system is a flat roof system with a concrete substructure, made of concrete beams (the I- and Y-beams, T-strands). High profiled sheet metal is mounted on the substructure to hold the moisture barrier, thermal insulation and the finishing PVC film.
FLAT ROOF SYSTEM WITH A CONRETE SUBSTRUCTURE (CONCRETE SLABS)
The elements of this root system are a flat roof with a concrete slab as substructure. In contrast to the system of concrete girders, this system does not use high-profiled metal sheets.
FLAT ROOF SYSTEM WITH A STEEL SUBSTRUCTURE
A flat roof system with steel substructure is also very commonly used. This system is basically the same as the flat roof system with a substructure made of concrete grinders. The only difference is in the steel roof substructure.
ROOF SYSTEM WITH SHEET METAL PANELS AND A STEEL SUBSTRUCTURE
The flat roof system with a steel substructure and a sheet metal sandwich panel with thermal insulation is also fairly common. A separation layer and PVC film is laid on the panel as a finishing.
PITCHED ROOF WITH A SLOPE SYSTEM
For this system, TPO roofing is fitted under the steel substructure. A TPO is a building slab, which is used for lining unheated roofs and facades. It is made of galvanized and painted sheet steel with 10 mm polyurethane spray coating, which prevents condensation and thus extends the service life of the covering and roof structure. The trapezoids are filled with a non-combustible mineral wool and the plate’s bottom side is finished with an aluminium foil.
If the polyurethane spray coating is not needed, TPF roofing is used instead of TPO. The TPF panels are made without polyurethane spray coating, but have the additional layer of fabric made of polyester fibres on the bottom. The main task of the fabric is to retain moisture from condensation.
