The thermal and optical performance of Mermet® solar protection fabrics are tested in accordance with the European EN 14501 standard. These values are necessary for set recommendations, but do not help when it comes to spontaneously selecting the right fabric.

This is why Mermet has developed a unique system to help make your choice, enabling the four requirement levels in a building to be qualified :

• Do you want to allow all the light to enter or not?
• Do you want to control on-screen reflections?
• Do you want to protect yourself against heat?
• Do you want to offer good visibility when looking out?
  

4 comfort factors to choose the right fabric for the function and colour required and ensure the success of your solar protection.

These 4 indices are determined for each fabric depending on its specific characteristics: weave, openness factor, colour, thermal and optical values.
