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. Depending on the chosen type of glass, frit or film, light and radiation transmission can be accurately achieved for every specific application.
Shadoglass shading systems are operated by linear actuators that have the capability to operate complete facades. The louvres are available in various colours, surface finishes and coatings to meet specific design requirements. Photovoltaic cells may be integrated so as to obtain further energy benefits.

Shadoglass Solar Shading System
Types available
There are five standard systems in the Shadoglass range. The leaflet (pages 4-14) provides further information.
System 1
Intended for wider spans, carrier system 1 incorporates a central aluminium torsion tube along the length of the louvre, and is ideal for continuous facades, as well as for roofs. For glass, cross sectional louvre widths from 300mm and up to 600mm are available. This carrier system is also suited for use with metal, fabric, wood, terracotta clay and translucent acrylic louvres, and is suitable for carrying photovoltaic cells.
Three torsion tubes are available:
Central torsion tube LS1-55:
Glass louvre system width: 350 - 500mm.
Vertical supports at 2500mm maximum centres.
Angle of rotation: 0-100°.
Central torsion tube LS1-65A:
Glass louvre system width: 350 - 500mm.
Vertical supports at 3000mm maximum centres.
Angle of rotation: 0-100°.
Central torsion tube LS1-65B:
Glass louvre system width: 420 - 500mm.
Vertical supports at 3000mm maximum centres.
Angle of rotation: 0-100°.
Project examples
System 2
Primarily intended for smaller spans or where frequent anchor points are available, carrier system 2 provides minimum obstruction to the glass area, thereby maximising daylight and enhancing the view to the outside. For glass, carrier system 2 is available with cross sectional louvre widths of up to a maximum of 500mm. This carrier louvre system is also suited for use with metal, fabric, wood, terracotta clay and translucent acrylic louvres.
The glass louvres are mounted on a choice of two aluminium support brackets:
Support Bracket LS2-30 ("C" shaped bracket):
Glass louvre system width: 500mm (maximum)
Vertical supports at 2000mm maximum centres.
Angle of rotation: 0-100°.
Support Bracket LS2-301 (straight bracket):
Glass louvre system width: 550mm (maximum)
Vertical supports at 2000mm maximum centres.
Angle of rotation: 0-100°.
Project examples
System 3
Carrier system 3 is centrally pivoted, intended for wider spans and incorporates a discreet central aluminium torsion tube along the length of the louvre. It is ideal for continuous facades as well as for roofs. For glass, louvre spans of up to 4000mm long can be achieved without any additional supporting structure. Glass louvres can have a cross sectional width of up to 600mm. Its two-piece aluminium cast pivots are dog-legged to allow the louvres to overlap thus providing noise attenuation, wind protection, ventilation in warm weather and insulation for the building during winter.
This carrier system is also suited for use with metal, fabric, wood, terracotta clay and translucent acrylic louvres, as well as photovoltaic cells.
Maximum glass louvre width is 600mm. Vertical supports are at 4000mm maximum centres. Angle of rotation is 0-100°.
Project examples
System 4
Shadoglass Systems 1 to 3 are centre pivoted systems which require the supports to be connected to each side of the louvre. Shadoglass System 4 provides a back hung design solution with hidden control mechanisms integrated within the main vertical supports. This allows for seamless continuous louvers with unobtrusive supports when viewed from the outside looking in, due to the louvers being in front of the supports.
For glass, carrier system 4 is suitable for smaller spans of up to 1800mm in length. It can utilise cross sectional louvre widths of up to 500mm, incorporating photovoltaic cells if required. This carrier system is also suited for use with metal, fabric, wood, terracotta clay and translucent acrylic louvres. Angle of rotation is 0-100°.
Project examples
System 5
Carrier system 5 is a fully centre pivoted system which provides maximum transparency. Louvres are supported at each end by a bonded and extruded end cap. For glass, louvre spans of up to 1800mm long can be achieved without any additional support work. This glass louvre system can utilise cross sectional louvre widths of up to 600mm. System 5 is ideal for either horizontal or vertical applications. This carrier system is also suited for use with metal, fabric, wood, terracotta clay and translucent acrylic louvres. Angle of rotation is 0-100°.
Bespoke systems
Colt realise the importance of creativity and individuality when designing a building and offer many bespoke solar systems in such materials as perforated aluminium, wood, terracotta clay, and translucent acrylics.
Construction
The principal support and control components are manufactured from aluminium and stainless steel. Aluminium extrusions are to BS 1474 Grade 6063 T6.
The glazed louvre panels are heat soak tested toughened glass with the edges treated to remove stress. Glass thicknesses of between 8mm and 16mm max are available. The glass specification will be tailored to suit each application, taking full account the project's aesthetic and performance requirements.
Photovoltaic Cells
With the exception of carrier system 2, Photovoltaic cells may be integrated into the glass louvre system, either laminated onto the reverse side of the glass panels or between the two sheets of a safety glass.
