Fabric Types

Sunscreen

  • Also known as screen fabric these fabrics tend to come in 4 different openness factors: 1%, 3%, 5%, and 10% - check the specific fabric to see the specification.
  • The percentage refers to how much of the fabrics surface area is made up of the space between the weave. Therefore meaning that 10% fabrics are the most open, and 1% fabrics are the most dense. Therefore a 10% fabrics lets the most light through and has the most visibility through it.

Light Filtering

  • Light filtering fabrics are also commonly broken down into two sub-groups, dimout and sheer fabrics.
  • Sheer fabric has a very loose weave, and as a general rule transmits a lot of light. They’re commonly chosen for their aesthetics rather than their functionality.
  • Dimout fabrics are fabrics that have a solid weave, and block a lot of heat and light. The only difference between dimout and blackout fabrics is that dimout options can still have a small amount of light ‘bleeding’ through.

Blackout

  • Unlike dimout fabrics, the ones under our blackout category maintain full light block. They commonly have a white backing to help reduce solar heat gain, although that isn’t always the case, check the specific fabric to be sure.
