Construction Guide


Radiated or otherwise layered, with a minimum thickness of 40 centimeters (concrete), reinforced with structural steel, cross-section and layout based on static design. Ensures a horizontal plane in order to build on it.

Galvanized steel skeleton

Hot-galvanized steel is applied in accordance with European legislation and in cross sections C and U in dimensions from 100mm to 300mm and thickness from 1.50mm to 3.00mm. The density of the uprights is determined by the structural design of the engineer. The cross sections are connected with self-tapping screws and special fastening anchors.
The steel used is cold-formed with hot galvanizing and high strength. As material conforms to EU standards. Hot zinc galvanizing 275g / m2 provides excellent protection against corrosion even after metal forming / cutting.

The advantages of steel

√ The construction is lightweight per square in relation to other construction solutions, offering seismicity and durability.

√ It is an industrial product of high standards and specific certifications.

√ Galvanized steel does not rust and does not wear over time, keeping its properties and strength stable.

√ It is recyclable over 90% and environmentally friendly.

Oriented OSB Fibers of Class 3

 OSB / 3 is used to cover the metal frame on both exterior and interior surfaces, floors and roofs, covering virtually the whole structure. OSB / 3 used in accordance with country and EU standards are used in accordance with the European Standards: EN 13986, EN 1058, EN 789, EN 300, which are certified by the Greek Standards Organization. Inside, after OSB, it is placed on the final finishing of the walls.


The advantages of OSB chipboard

√ Resistance to moisture and stable geometric and mechanical properties over time.

Good thermal insulation behavior.

Stiffness and lateral support to the metal frame.

Surface of the surface

Quick application.

Good base for external thermal insulation systems.

Fully recyclable and environmentally friendly material.

Antimicrobial treatment.

Building insulation

Inside the OSB and between the uprights is placed 8 cm of KNAUF mineral wool for greater thermal insulation performance. In addition, an integrated finishing system of the construction is applied, which simultaneously offers thermal insulation and waterproofing throughout the construction, the thermal face system. The basic materials of a typical external thermal face system are:

√ Coating of OSB / 3 with expanded polystyrene thickness of 5 cm (EPS80).

√ Fixing the plates with anchors.

√ Alkaline grid

√ Basic layer of ready-mixed plaster.

√ Final layer of ready-to-paint silicone plaster.

The advantages of the external thermal face


√ Minimum energy consumption for cooling and heating of the structure.

√ High noise and acoustic factors within the structure.

√ Elimination of thermal bridges, reducing the possibility of water vapor formation on the surfaces of the construction and mold problems. Ready made plasters of exceptional quality and elasticity prevent cracking.

√ Prepared plasters of exceptional quality and elasticity prevent cracking.

√ Optimal protection of the bearing steel body from environmental conditions.

External frames

Aluminum thermal breaks of branded companies are used, but there is the possibility of installing PVC frames also of branded companies.
