Sunscreens – the balance between light and shade
Sunscreens have become the product of choice for shading windows in Canadian businesses and it is easy to understand why.
 
Maintaining your outside view
The unique weave of Sunscreen fabrics allows a view through the fabric from the area of lesser light to the area of greater light. That means that during the day, building occupants can see through the fabric to the outside, while there is a high level of privacy from people looking from the outside into the building. The darker the colour, the greater the amount of light transmitted, hence the better the view through the fabric. In fact, black fabric provides very little obstruction to the view outside.

Sufficient natural light
Human beings crave natural light. It sets our body clock and triggers the sensation of colour in our brain. The open weave of Sunscreens filters natural light – the higher the openness factor and the lighter the colour, the more light is transmitted.

Shading
Outside, sunlight can vary in strength from as much as 100,000 lux to less than 10,000 lux, but inside we need from 100 to 1000 lux, depending on the task. Most often we need a light level of 300-500 lux, so windows must be shaded to reduce the quantity of light entering the room. As a rule of thumb, maximum luminance differences between the window, walls and computer screens should be 30:10:1.
Sunscreens transmit around 5% to 25% of the outside light, depending on the weave and colour, and so provide significant shading that supplements the shading provided by the glass.

Glare reduction
Reflections and high luminance variations cause eye discomfort, particularly where people are using computers.  Sunscreens provide uniform shading across a window, eliminating light spots and annoying reflections. The darker the colour, the greater the glare reduction.

Heat protection
The need for heat protection is a key consideration in the comfort of the building occupants and the cost of cooling the building with air conditioning.
Sunscreens transmit as little as 7% of heat, depending on colour and weave. Lighter colours and less open fabrics reflect more heat than darker colours in more open weaves. Sunscreens provide the greatest heat protection when fitted externally, as they stop most of the sun’s rays before they reach the glass.
 
UV protection
The need for UV protection for people is well known. UV radiation also damages furnishings – unprotected carpets near windows can fade within months.  Sunscreens filter UV radiation, reflecting up to 94% of the UV radiation that is transmitted through the window

Energy benefits
Shading that is fitted to a building provides significant reductions in solar heat gain, while reducing UV rays.
Automated Sunscreens can be connected to Building Management Systems for optimal control of air conditioning loads and comfort of the building occupants.

Environmental and employee benefits.
The light filtering effect of Sunscreens means that the use of natural light in the workplace can be maximised, which is important for
individual productivity and well being as well as reducing the need for artificial lighting during the day.

Product overview
Sunscreens are available as interior Roller Blinds, Roman Shades, Panel Glides. Sunscreens allow the building occupants to enjoy their view and natural light whilst providing low light transmission, glare reduction and excellent shading values. New fabrics are constantly in development including eco-friendly GreenscreensTM.
Hardware specification overview Rollershades and Sunscreens are available in spring, chain or automated operating systems. Chain control, automation and spring control utilise extruded aluminium roller tube and hard-wearing UV resistant plastics.

Durability
Glass fibre based fabrics possess inherent strength, dimensional stability and chemical resistance. Polyester fabrics are also available to provide an environmentally friendly option while still offering high levels of performance. Sunscreens are naturally resistant to growth of mould and mildew and are easily cleaned. The colourfastness of the fabric is 6-7 blue scale (where maximum score is 7) (AS001.4.21). The operating hardware is cycle tested to ensure long term durability.

Applications
Situations where view retention is required while providing shading and glare reduction, e.g. Audio visual rooms, computer work stations and open plan living areas. Applications where natural light is desired whilst providing some shading e.g. restaurants, galleries and exhibition spaces, public spaces, schools

Fire retardant
Some Sunscreens are suitable for use in Class 2-9 buildings
according to the Building Code of Australia. Refer to the fabric
sheets in this manual.

Warranty
Sunscreens are covered by a 3 Year Warranty. Conditions apply.
All motorized components are covered by Somfy's 5 year warranty

Automation
All Sunscreens and Rollershades can be automated with remote
control, wall switches, RF or linked to Building Management Systems.
