Note: Based on a 1m x 1m size. Smaller louvres may have a higher Pressure Drop.
- Aluminium alloy 6063-T6
- Finition laminée
- Clear or colour anodised
- Polyester powder coated Matt (standard) or gloss
The principal reason for using louvres is to allow the movement of air. But, louvre specification is a balance between form and function, with louvred façade appearance playing an important part in the selection process.
