Naco Louvre Windows

 Naco LouvresA practical solution for control of light, sound and airflow. Naco Airflow louvre fittings are supplied as a kit to your specifications, ready to install in aluminium or timber frames. Glass or aluminium blades are available.

Benefits of Naco Airflow louvres:

  • Rust-resistant, fully housed mechanisms, with smooth operation
  • Durable finish - anodised, painted or powdercoated in a range of colours
  • Precision-fit blade holders to ensure positive blade contact
  • Built-in compression-fin draught eliminators on blade holders
  • Adaptability for optional factory-fitted security bars
  • Multiple-handle operation options for versatile breeze control
  • Adaptability for motorised remote-control operation

Planning and Specifying louvres:

  1. Calculate the number of blade required from the following table.

  2. Extended window heights (i.e. higher than standard sizes listed and within the next blade height) require fixed, custom-sized infill panels to fit remainder of opening depth.

  3. A fixed head weatherbar should be used above infill panels.

  4. For Naco louvres the recommended maximum single blade length is 760mm. See diagrams to calculate louvre blade widths.

Blade-Lok Louvres

BladeLok

Benefits and features of BLADE-LOK Louvres

  • Fitted with two poly-pile edge strips to keep out dust, rain and to reduce drafts. Improved strutting has eliminated annoying wind rattles

  • Combined locking and operating handle with a plastic tip to ensure comfortable and firm control. Left hand control is standard but can be supplied on the right to special order

  • Manufactured from robust aluminium with anodised or epoxy powder coated weather-proof finish providing strength and attractive appearance

  • Fitted with a patented BLADE-LOK security clip which prevents glass being removed when the louvre is in a locked or open position. Glass blades are not supplied with the louvre fittings but are stocked by glass merchants in various types. Can be tinted with film just the same as any glass window

  • A set of Cooper De Luxe Louvres consists of two aluminium mullions with attached operating mechanism and channels for holding the glass blades. These mullions are not joined together in any way and therefore can be spaced to fit any width opening with the maximum recommended of 762mm

Installation Instructions

  • Before installing the louvre fittings, make sure the frame is square and true throughout. Failure to observe this fundamental instruction will cause the louvres to be stiff in operation and could result in air and water leakage.

  • When screwing the louvre mullions to the side frame ensure that they are exactly parallel and opposite each other. Providing the frame is plumb in all directions this may be done easily by scribing a guide line down either jamb at equal distance from the outer face.

  • Ease back the glass retaining clips and then insert the glass blade. When this is fully home the clip must be bent over the top edge to retain the blade in its correct position.

  • The louvre must be in the locked position when fitting the sillboard at the bottom and the cover bead at the top. These should be brought up to but NOT pushing against the glass. This will ensure the weather-proof seal between the blades is maintained. This is most important as most complaints concerning faulty operation of the louvre are due to incorrect positioning of the sill-board or cover bead forcing against the glass preventing the blades sealing correctly.


Trimline Louvres
