• Solar C brise soleil

Solar C fixed brise soleil solar shading system

Solar C is a simple and effective fixed aluminium C-section brise soleil solar shading system designed to reduce heat gains and glare. It is positioned around or above windows.

It offers architects and contractors a versatile and practical solution to managing solar radiation, whilst adding a modern architectural aesthetic.

Fixed brise soleil devices such as Solar C are most effective on facades where it is possible both to reduce the amount of high angle sun in the summer, but also to allow low angle sun in the winter, which can then provide some passive solar heating.

Product information

Features and benefits

Versatile - Solar C can be mounted above or in front of windows and, as with all Colt solar shading systems, the louvres can also be mounted around corners and curves. This, combined with the various angles at which the system can be installed, ensures that the shade created is always optimal. The versatility of the system, with respect to dimensions and colours, offers many design alternatives.

High light transmission, low heat transmission - Unlike conventional 'Z' shaped blades, which reduce both direct and diffused light, the Solar C blade is designed to be particularly effective at controlling solar heat gain while allowing a large proportion of diffused light through the blade.

Potential to reduce installation time – Alternatively Solar C can be provided in modular pre-assembled form and also as a panellised system.

Six blade profiles are available varying in width from 100mm to 150mm. A perforated blade is also available with a width of 110mm. The pitch between the blades is normally set at 100mm but this can be varied to suit the blade size and angle.

Five basic Solar C brise soleil rafter designs are available. Their use depends on the fixing method and the loadings on the structure. For any projections less than 1m the rafter can be cantilevered from the building structure, assuming the wind load is not excessive. Maintenance walkways with kick plate and hand rails can be attached to the rafter to enable access for cleaning.

Solar C is normally provided as a continuous brise soleil louvre system mounted either above or below fixed rafters projecting from the building. However, if a panellised system is preferred, then this is available with profiled end plates which can make a prominent feature to a building. This can also reduce installation time.

Installation of Solar C

With continuous brise soleil louvres, the louvres are sent out in breakdown for on-site assembly, unless it is supplied in modular pre-assembled or panellised form. An adjustment in the louvre system can accommodate building tolerances of +/- 10mm. Particular attention is required to suitable fixing locations and the structural integrity of the fixing material. This should be considered at the early stages of the project.

Design service

We 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, we can work with the customer from the earliest stages of the project to design an aesthetically pleasing, high performance solar shading system.

We also offer complete project management and installation, which means that we take complete responsibility to ensure that the product is in full working order within one package of works.

Please contact us for more information relating to the application, specification or installation of Solar C.

Support rafters

Five rafter sections are available, together with a bracing strut - their use depends on the fixing method and the loadings on the structure.

  • Type TR 15/30: 15 x 30 mm channel section fixing to steelwork
  • Type TR 23/30: 23 x 30 mm double channel floating intermediate section

  • Type TR 90/30: 90 x 30 mm extended double channel section

Rafter selection subject to system design

  • Bracing Strut 20/20: 20 x 20 mm rectangular box section

Maintenance walkways with kick plates and handrails can be attached to the rafter to enable access for cleaning.

Support clips

Fixed and adjustable plastic support clips are available, grey or translucent. The plastic clip allows for thermal expansion of the blade.

  • Adjustable clips: Allow complete flexibility of louvre and rafter angle. For visual and thermal performance the louvre angle can be changed on the rafter. The louvre clip is adjustable in increments of 15°. The action of attaching the louvre blade fixes the angle.
  • Fixed clips: Available in 30, 45, 60 and 135° to set the louvre angle.
