OUR AL SYSTEMS
Aluminum opening system 38mm - O38
- Structural width - 38 mm
- Available with single glass - 4 mm, 5 mm, 6 mm, 8 mm or 10 mm, double glass - 18 mm or 20 mm
- Water resistance class - 7A and 7B
- Wind resistance class - C2
- Air permeability - class 4
- Air noise insulation - R w (C; C tr ) = 32 (-2; -4) dB.

This type of profile is made entirely of aluminum. The best option for this system is internal partitions, they do not have large temperature amplitudes so there will be no condensation. Its main advantages are elegant appearance, lightweight construction, low price for the material!
Aluminum opening system with interrupted thermal bridge 55 mm
- Structural width - 55 mm
- Double and triple glass - 24 mm, 28 mm, 32 mm or 38 mm.
- Water resistance class - 9A and 7B
- Wind resistance class - C2

- Air Noise Insulation - R w (C; C tr ) = 37 (-1; -2) dB
- Max heat transfer coefficient of the window - Ug = up to 0.7 W/m 2 K
- Heat transfer coefficient of profile system Uf = 1,6 W/m 2 K
Aluminum opening system with interrupted thermal bridge 70 mm
- Structural width - 70 mm
- Double and triple glass - 24 mm, 32 mm, 38 mm or 42 mm.
- Water resistance class - 3A
- Wind resistance class - C2
- Air permeability - Class 4
- Air Noise Insulation - R w (C; C tr ) = 40 (-1; -4) dB
- Max heat transfer coefficient of the window - Ug = up to 0.6 W/m 2 K
- Heat transfer coefficient of profile system Uf = 1,5 W/m 2 K

OUR SLIDING SYSTEMS
Lift and slide system TBS60
The sliding system of this type is made of aluminum profiles with interrupted thermal bridge. The size of the doors can be within the range:

80 cm width x 160 cm height.

We use the mechanism of the German company HAUTAU, which is a guarantee of reliability and quality.
It is able to withstand a glass unit of 300 kg - 400 kg.

Painting is typical for all aluminum systems*. Thickness of double-glazed windows: 24 mm, 28 mm, 32 mm and 42 mm, also mosquito nets can be installed.
Also, we use other systems:
- S28 sliding system (cold aluminum)
- Profilink PVC sliding system
- PVC and aluminum tilt sliding door mechanism
