Tensioned shading systems require technical fabric that is strong and stable, whilst meeting environmental and aesthetic design criteria. Our fabric collection has been selected by our engineers to provide an optimum combination of these factors.
Standard Screen Fabrics
with a range of openness factors for optimum visual comfort and heat protection.
Specialist Screen Fabrics
with advanced materials and finishing techniques such as metallisation for best in class heat protection, glare control, and aesthetic finish.
for complete light control, privacy, and insulation.
Data values explained
The Gtot, or total solar energy transmittance, is the percentage of solar energy that reaches the interior of a building, penetrating through the blind and glazing. It is calculated from a number of factors, including direct transmittance (Ts), reflectance (Rs), and absorptance (As), as illustrated here on an external shading system.
The closer the fabric’s index is to 0, the more efficient it is in terms of protection against the sun’s heat.
Glare and comfort is subjective, but a Total Transmitted Light (Tv) value gives an indication of fabric performance in regulating brightness, reducing glare and managing contrast. The Tv value of a fabric is the total percentage of daylight transmitted into the room, made up of two elements; the direct light through the open spaces of the fabric and the light that is diffused through the fibre.
Maintaining view-through for visual comfort and wellbeing, whilst managing glare is possible through a combination of colour choice and openness. The application of specialist fabric coatings widens the colour choices available and is extremely beneficial for solar energy control.
There are thousands of technical fabrics on the market, many of which are compatible with TESSTM systems. For fabrics outside of our approved collection, we can carry out a desktop suitability assessment at no charge. Alternatively, you can submit a sample of the fabric to our testing service, used by many of the industry’s fabric experts as a performance benchmark.
