Colt Shadoglass is a fixed or controllable external glazed solar shading system (glazed louvre system) that may be installed either vertically or horizontally in front of the façade.
This louvre system is also suitable as a primary or secondary facade element for ventilation.
It may be combined with other Colt products such as rooflights and glazed facades. Also Coltlite for glass louvre - natural glass louvred ventilators - could be of interest to you.
A Shadoglass controllable or fixed architectural glass 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. Depending on the chosen type of glass, frit or film, light and radiation transmission can be accurately achieved for every specific application. Photovoltaic cells may be integrated so as to obtain further energy benefits.
Shadoglass shading systems are operated by linear actuators that have the capability to operate complete facades. Such systems comprise a series of glass louvres mounted onto a building which are attached to a system of levers and push rods which link them to a control system. The louvres may be fixed at any angle and can rotate under motorised control within a range of up to 90º (85º with LS-4).

Shadoglass Solar Shading System
Many options
The various Shadoglass carrier systems are suited for use with glass, metal, fabric, wood, terracotta clay and translucent acrylic louvres, as well as photovoltaic cells.
The louvre spans depends on structural considerations and the kind of louvre blade selected.
Shadoglass is well suited to many different applications, from façades to glazed roofs. Such a louvre system can be either fixed or moveable, and positioned either horizontally or vertically.
See the specification page for further details.
Generic types
Shadoglass has five basic carrier systems:
Shadoglass LS-1 is centrally pivoted, intended for wide spans, and incorporates a central aluminium torsion tube incorporating the louvre brackets along the length of the louvre for additional support.
Shadoglass LS-2 is primarily intended for small spans or where frequent anchor points are available. It provides minimum obstruction to the glass area, thereby maximizing daylight and enhancing the view to the outside.
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.
Shadoglass LS-4 is a back hinged system with hidden control mechanisms integrated within the main vertical supports. This enables a seamless continuous appearance when viewed from the outside, since the supports are installed to the back of the louvres.
Shadoglass LS-5 is a centre pivoted system which provides maximum transparency. An aluminium clamping system is fixed along to the short edges of the louvre blades.
Robust design
All components including the supporting construction are manufactured from extruded aluminium alloy with stainless steel fixings.
Sitework
Shadoglass can be provided in modular pre-assembled form to reduce time on site.
Controllable versus fixed fins and control routines
A fixed solar shading system may only truly be effective on a south facing building.
Controllable solar shading systems can better optimise the flows of heat and light energy than fixed solar shading systems. Since the louvres are designed to follow the path of the sun, daylight levels may be optimised whilst radiation levels are reduced to a minimum. The likelihood of over-shading or under-shading that frequently occurs with fixed solar shading is reduced, since the louvres are always set to optimum shading angle.
On dull days, light sensors can operate to fully open the fins to allow the occupants full vision to the outside at all times.
An additional benefit is that when they are closed, moveable Shadoglass louvres can provide additional security and can help reduce winter heat loss.
Controllable Shadoglass louvres can pivot through 90 degrees and can be controlled by astronomical data operating the actuators to track the path of the sun.
Colt ICS 4-Link or Soltronic are the standard controls for Shadoglass. These provide accurate control of the louvre blades, continually calculating the position of the sun and together with internal temperature and lighting sensors controlling the position of the louvres. Remote operation is also available via an internal modem interface.
Design service
Colt can assess a client’s design and provide a bespoke solution to meet all aspects of a project. Backed by an experienced technical support team, Colt can work with the customer from the earliest stages of the project to design an aesthetically pleasing, high performance solar shading system.
