ARi Hidden Leaf System
Opening system with RPM - 60 mm

Opening system with hidden leaf, european chamber and central sealing in EPDM, with thermal break obtained by insertion of sticks of polyamide type ómega with 24 mm, reinforced with 25% of glass fibre.

The sections of rim and fitment are 60 mm, with an average thickness of aluminium profiles of 1,5.

There are possibilities for straight or curved sheet.

Opening possibilities:
• Interior opening: folding, tilt/turn.

Acabamentos:
• Polyester powder coated colours;
• Wood effect paint;
• Anodizing.
