Our conventional fabrics utilize simple colors and patterns with proportional weaves. These fabrics are designed to provide optimal view through and solar control.
Our decorative fabrics feature unique coloring, weaves and textures. They are available in a variety of aesthetic styles that enhance the beauty and elegance of interiors.
Total Solar Reflectance (Rs)
The % of solar energy directly reflected by a material
Total Solar Absorptance (As)
The % of solar energy absorbed by a material
Total Solar Transmittance (Ts)
The % of solar energy directly transmitted through a material
Reflectance in the Visible Spectrum (Rv)
The % of visible light reflected by a material
Transmittance in the Visible Spectrum (Tv)
The % of visible light directly transmitted through a material
Openness Factor (OF)
The % of shade fabric made up of holes
Solar Heat Gain Coefficient (SHGC)
The % of solar energy reaching the interior of the building.
The combination of Rs, As, and Ts to equal 100% of total solar energy. The total of each property (Rs, As, Ts) is measured and reported as total solar energy, and it is also broken down into separate values by ultraviolet (UV), visible and infrared (IR) spectrums.
Solar Fabric Weave Types
This pattern gives the best view-through of any weave pattern due to the equally-sized square openings created in the final fabric.
This is the simplest weave pattern, creating no distinct front or back.
Mock Leno Weave
This pattern utilizes separation of grouped threads to create openings that allow for good view-through capabilities in the final fabric.
This pattern uses a larger yarn and exhibits a “ribbed” line effect in both the warp and weft direction.
This pattern includes any weave that doesn’t fall into plain, twill or satin categories but still results in a textured surface or pattern.
This pattern has more identifiable room vs. street sides. Each yarn row is offset from the previous in order to give a diagonal rib pattern. Each of these diagonal lines is called a wale. The wale is most visible on the room-side.
This pattern creates a dual-sided fabric with the intended street-side fabric being predominantly white, providing added heat protection. This pattern provides different interior room-side color schemes while maintaining exterior uniformity due to the white street-side appearance.
