The blinds consist of a transparent solar film fitted to an aluminium roller which may be spring loaded, friction or chain ball side operated.

Where conditions dictate, the roller blind can be mounted inside a cassette which will protect the film from dust, hostile atmospheres and possible mechanical damage when not in use.

Solar films consist of thin layers of polyester which can be clear or dyed to various colour specifications and degrees of darkness to produce the anti-glare effectiveness of the film with a resultant benefit of reduced eye strain.

There may also be a micro-thin coating of aluminium between the layers which rejects infra-red rays and gives the film its heat reflecting/heat rejecting properties.  This feature can reduce heat build up and mean a saving in air conditioning power consumption and costs.

All solar films absorb over 97% of UV light which reduces the fading effect (anti-fade) and other destructive features of sunlight such as skin damage.

Types

• Grey/silver film - offers a high degree of glare protection combined with a high degree of heat reflection.
• Grey/grey film - this film has excellent glare protection without the obvious reflection associated with the above.
• Bronze/bronze film - almost the same properties as grey/grey but with a bronze hue.
• Grey/gold film - highly heat reflective with excellent anti-glare properties.  The most effective of all the films.
• Clear film - anti-fade only.  Used mainly in shop windows and hospital dermatology wards.
• Amber film - anti-fade with a little heat and glare rejection.  Used mainly as shop window blinds.
• Components - see roller blinds
