Frame:

• Material and Coating: Constructed from steel profiles (S235JR and S355MC, EN 10025-2), the frame is coated with a 120 µm thick polyurethane paint for corrosion resistance, conforming to ISO 12944-2, Class C3M. The standard color is RAL 9002.
• Dimensions: The frame dimensions are 2435mm x 4880mm.

Floor Insulation:

• Construction: The floor structure includes steel crossbeams with smooth, galvanized steel sheets (0.5mm thick, DX51D according to EN 10327) underneath, providing protection against corrosion.
• Insulation: Insulated with mineral wool (thermal conductivity λ=0.040 W/mK) and a polyethylene vapor barrier (80 µm thick) on the upper side. The floor insulation thickness is 100mm with a U-value of 0.35 W/m²K.
• Top Layer: Covered with a 20mm thick water-resistant particle board (EN 312, P3, E1, D-s2 classification).

Ceiling Insulation:

• Construction: The ceiling consists of steel profiles (S235JR and S355MC, EN 10025-2), with wooden purlins spaced at 500mm intervals and galvanized steel sheets (0.5mm thick, DX51D, EN 10327) forming the flat roof.
• Insulation: Filled with mineral wool (thermal conductivity λ=0.040 W/mK) and a polyethylene vapor barrier (150 µm thick). The ceiling insulation thickness is 100mm with a U-value of 0.36 W/m²K.

Walls:

• Panels: The walls are made of FTVL panels with 60mm thick mineral wool insulation (thermal conductivity λ=0.040 W/mK), providing a U-value of 0.57 W/m²K. These panels comply with EN 13162 and have an A1 fire rating according to EN 13501-1.

Windows:

• Material and Glazing: Windows are constructed from three-chamber PVC profiles, featuring double-glazed insulating glass units (4/15/4 mm) with a thermal transmittance (Ug) of 1.1 W/m²K. The standard window size is 885mm x 1372mm with an overall thermal transmittance (Uw) of 1.6 W/m²K.
• Type: Windows can be opened vertically or horizontally, excluding sliding windows, and are equipped with double sealing for improved insulation.

Doors:

• Material and Construction: Doors are made from painted aluminum profiles with a 40mm thick leaf, composed of galvanized and painted steel sheets (0.5mm thick, DX51D, EN 10327) and filled with 40mm thick styrofoam (EPS). They have a thermal transmittance (U-value) of 1.8 W/m²K.
• Features: Each door includes a cylinder lock, metal handle, and complies with CE certification according to EN 14351-1. The standard door size is 905mm x 2060mm.
