Continuous Blade Louvres


  • Louvre flexibility
    - Site assembled louvre for large openings where
    continuous streamlined appearance is required.
  • Unlimited Louvre widths
    Vertical louvre supports are normally spaced between 1200mm and 1800 mm centres to enable louvres of virtually any width to be specified
  • Standard or Weatherproof adjustable blade Louvres
    for use in both internal and external building applications.
  • Blade Performance
    - blade design minimises pressure drop characteristics throughout the louvre.
  • Louvre depths
    Available !n two different depths (100mm and l50mm) .
Louvre heights -
  • Available in a full selection of standard heights (see table) giving maximum free inlet area.Louvres can be manufactured in other non-standard sizes .
  • Factory assembled
    Quality manufactured in a variety of materials and finishes to suit specific aesthetic requirements.
  • Easily installed
    - rapid fitting into all wall types on site to blend into aesthetic requirements.
  • Minimal maintenance
    Occasionally clean the louvre. Protective metal and fittings maximises corrosion resistance.
  • Coefficient of discharge
    Performance tested at a guaranteed minimum of 0.63 for 100mm deep louvres and 0.68 for l50mm deep louvres

Optional Accessories

Bird / insect screens
- to eliminate entry of birds and insects, with screens fitted to the internal face.
Additional steelwork
- where multiple louvres are used on large openings.
- can be supplied to meet individual customer requirements

Pressure Drop and Free area

When designing any ventilation system, pressure drop through a louvre should be considered. The percentage of free area to the whole louvre face area is a function of height and width. Refer to the appropriate Ellflow Louvre Performance Chart to determine the actual pressure drop through the louvre and the free area.
Each Louvre Performance Chart shows pressure drop (Pa) at air velocities (m/s) through the free area of the louvre.
