Options

• Interior opening windows (casement, tilt & turn, hopper).

• Integrated into a curtain wall windows.

• Single doors.

• Double doors.

• Integrated into a curtain wall doors.

• Exterior opening doors.

• Interior opening doors.

• Doors with high basement profile.

• Doors with automatic threshold.

Advantages

• Max. dimensions of doors and windows made of ALTW72 system are higher than of those made of wood and plasti

• In addition, high strength and easy maintenance increase significantly the operating period of doors and windows made of aluminium profiles.

• High thermal parameters of the profiles are comparable with best wooden frames.

• High level of sound insulation.

• Wide range of profiles and technical solutions.

• Simple and faults excluding assembly technologies.

Aluminium and combined profiles

Profiles are made of AlMg0.7Si EN AW-6060 T6 alloy, which is resistant to corrosion and allows manufacturing high precision profiles. Combined profiles are made with the use of thermal insulating glass-filled polyamide profiles produced by leading European suppliers. Great strength characteristics of combined profiles are ensured by modern technology of joining different materials.

Gaskets

EPDM-based rubber gaskets are used to seal the glazing, sash-frame junction and ensure condensation drainage. Physical-mechanical properties of gaskets meet DIN 7863 requirements. Operation life is at least 15 years.

Fastening elements

Fastening elements used to connect profiles and other components are made of aluminium and stainless steel.

Hardware

The system provides for the use of hardware from leading suppliers (Savio, Fapim, Giesse).

Types of coating

Aluminium profiles are coated by protective-decorative polymeric layers (width: 60 micron at least) or anodic layer (width: 20 micron at least). The colour range includes any RAL-colour and 11 anodizing colours.

It is quite popular to apply two different colours for exterior and interior part of combined profiles.

The high quality of coating is confirmed by Qualicoat and Qualanod international certificates.
