How Solar Screen Shades Work
How Solar Screen Shades Work
Onthank Interiors handles roller shades from QMotion, Mariak, Hunter Douglas, Kirsch and Alta. Trying to pick the right fabric can be confusing. Here is some tips on selecting Solar Screen fabric.
Solar Screen Shades Block the Sun, but Not the View!
Solar screen fabric is available in a wide variety of colors, styles, and openness factors to meet almost any criteria. These fabrics fall into three categories; dark fabrics, light fabrics, and high performance reflective fabrics, all of which provide:
Natural Light Management
View through connection to outside
High Performance Solar Screen Shades
High performance solar screen fabrics are designed to outperform light and dark fabrics when a project requires excellent heat control, glare control, UV protection and view through characteristics. High performance fabrics like SilverScreen and EnviroScreen have a highly reflective exterior regardless of the room-side color. Metallized high performance fabrics are able to provide low visible light transmittance (VLT) values in combination with low shading coefficient (SC) values, independent of color. Typical light and dark colored solar screen provide a dedicated solution where one or two criteria are required or deemed the most important.
For excellent view through and glare reduction select dark colored fabric
For excellent heat management select a light colored fabric
For view, glare control, heat reduction select high performance fabric
Dark-colored Solar Screen Shades
Dark fabrics provide excellent glare control by reducing the visible light that comes through the fabric. Fabrics that block 94%-96% of the visible light provide excellent glare control characteristics, and will absorb some heat and keep it at the window until it dissipates into the room. In applications where passive solar warming and glare control are desired, dark colored solar screen fabrics are optimal.
Higher AS (Solar Absorbance) values mean more light and heat is absorbed,
Lower VLT (Visible Light Transmission) values mean less light passes through the fabric, resulting in excellent glare control
Light-colored Solar Screen Shades
Light colored fabrics are more effective at reflecting heat, and allow more visible light into the room. Fabrics that block 80-90% of the visible light are an excellent choice for providing more light where windows are small, and in common areas where a lighter, brighter ambience is desired. Light is filtered, and view through the fabric is similar to a sheer drapery.
Higher RS (Solar Reflectance) values mean lighter colors reflect more heat away
Higher VLT (Visible Light Transmission) values mean more daylight is allowed to pass through
WHY Solar Screen Shades work- the science behind the fabrics
Solar screens are a marvel of science! Solar Screen mesh shades control heat and light, allowing a lower percentage of both to enter the room. Fabric color and density determine the solar/optical/thermal performance of individual fabrics. No single fabric has the precise combination of thermal/optical properties to satisfy every application requirement. The combination of properties of each fabric allow for a perfect match for every application and aesthetic. Your dealer or the fabric expertise of Onthank Interior’s customer service staff are available to help you make the perfect fabric choice for your needs.
