Description

Louvres for roof-top screening. The panels have a steel construction for strength and durability and are available in two designs: Italia-100 for 100% visual screening and Italia-80 for 80% visual screening. Italia-100i and Italia-80i are manufactured with the louvre blades inverted to face upwards, which maintains the visual screening properties from ground level.

Each installation is individually designed to include single or double access doors and panels which can be shaped to accommodate ducting, parapet walls, conduit or any roof obstruction. Products are finished hot-dip galvanized with an optional powder coated to any RAL colour.

Site conditions:

- Pre-existing roof membrane or bitumen coating:

Panels can be supplied with a free-standing framework specially designed for roof-tops. The adjustable framework is attached to non-penetrative feet which have a high tensile strength and an anti-slip ethafoam pad to distribute the load. The system is ballasted for wind loading and is designed to carry panels up to 2 m high.

- New builds:

Where the screening is installed prior to the application of any roof finishing treatment or waterproof membrane, panels up to 3 m can be supplied with posts which are manufactured with base plates for fixing directly to the roof.

- Existing structural support:

Custom-sized panels can be supplied to any height with framing to suit the required fixing method.

Standard product features

Material:

Electrofused steel S235JR.

Framing:

The panels are framed on two sides.

Product Options

Arrangement:

  • Bespoke designs: The integrity of the raw material allows it to be cut or shaped to suit non-uniform openings.
  • Secondary steelwork: Designed and supplied as required.

Orientation:

  • Italia-80 and Italia-100 panels: Designed with the louvre blades sloping downwards. If panels are required to be rolled to a radius, the louvres must have a vertical orientation.
  • Italia-80i and Italia-100i panels: Designed with the louvre blades sloping upwards which provides more effective visual screening for roof-top installation when viewed from ground level.

Bird and insect screens:

Panels can be framed with an angle section on all four sides to provide a mounting surface for bird and insect screens or blanking plates.

Finishing:

Polyester powder coating is a multi-stage process which applies thermo-setting resins, producing a significantly superior finish to painting.
