Modern Construction Methods Used In Metal Louvers Roofs 4 From 4

The distance between the moveable Louvre panels and the glazed roof below is made sufficient to allow for access for cleaning the glass below and the Louvre assembly itself.

Electrically operated Louvre canopies are also used for horizontal and inclined glazed roofs, excluding up to 90% of solar heat gain when set at a 45oangle.

Louvre blades are 75mm-l00 mm in typical proprietary systems but blades up to 300 mm wide can be made as a single extrusion.

Nylon sleeves and washers are used at the connection of moving parts, rather than metal, to avoid the need for regular lubrication.

Louvers can be solid or perforated to

different percentages of solid to void, from around 10% void to a maximum of 50%.

though the latter is difficult to fabricate.

Louvers are fixed by steel pins into a sliding

aluminum section at each end of the profile.

The Louvers are also fixed at their centering section.

As the sliding aluminum rod moves.

opening and closing together.

The sliding rods are connected at each end of the louvers and are fixed to a supporting frame of aluminum I-sections.

The single tube is powered by an electric’ motor, and as it Tums, the sliding arms move through the arrangement of gears.
