Shadoglass LS-3 glass louvred solar shading system

Shadoglass LS-3 is centrally pivoted, intended for very wide spans. An aluminium clamping system is fixed along to the short edges of the louvre blades. Its carrier system is suitable for use with glass, metal, fabric, wood and translucent acrylic louvres, as well as photovoltaic cells. Shadoglass LS-3 can be either fixed or moveable, and positioned either horizontally or vertically.

A Shadoglass shading system can reduce solar heat gain, lower air conditioning running costs, and lessen glare whilst maximising the use of natural daylight. Shadoglass louvres are available in various colours, surface finishes and coatings to meet specific design requirements, allowing the quantity of heat and light entering the building to be controlled.

Features and benefits:

  • Shadoglass is entirely customisable.
  • Reduces energy consumption, with high solar shading performance and reduction of glare to the internal space. Depending on the chosen type of glass, frit or film, the desired transmission of light and/or heat radiation can be accurately achieved for every specific application.
  • Movable option: can be operated by linear actuators that have the capability to operate complete facades.
  • Of robust, corrosion resistant materials.
  • Can be provided in modular pre-assembled form to reduce installation costs.

Product Options


  • Blade length: For glass, maximum 4000 mm long without any additional supporting structure.
  • Blade width: For glass, maximum 600 mm.


  • For glass louvre blades, consider their type, interlayer, colour, thickness, polish, frit, tint, edge treatment. Colt can advise on these aspects.
  • Side support arms, mounting brackets and support struts: Aluminium. Fasteners are stainless steel.
  • Aluminium components can be supplied with mill finish or polyester powder coated. Consult with Colt for availability of colours and to obtain samples.


  • ICS 4-Link: Provides accurate solar control and is particularly suited to larger projects. The system continually calculates the position of the sun and together with internal temperature and lighting sensors, controls the position of the louvres. Remote operation is also available via an internal modem interface.
  • Soltronic: A simplified version of ICS 4-Link, suitable for small to medium sized projects.


Consult with Colt for recommendations and details. Shadoglass can be provided in modular pre-assembled form to reduce time on site.

Structural considerations:

  • All spans subject to wind load calculations. Deflection of the louvre is limited to span / 100. Deflection of supporting structure is limited to span / 100.
  • Accommodation of thermal movement to be taken into consideration.
  • Structural tests of glass louvres may be necessary.
