Graber Solar Blinds And Shades – Aspects To Check


Graber Solar Blinds And Shades are one of the best options when you are looking for purchase window treatments. In the following sections let us look at few of the aspects you need a check to select the right shades.

Heat Absorbance | Glare | Shading Coefficient | Heat Weldable | Indoor Environment and Safety

When selecting fabric for the solar shade you will have to look into different options. Let us go through the details here.

# Heat Absorbance

Suppose there is a fabric with 14% openness and 105″ width, which is suitable for both exterior and interior application. The fabric will usually be available in its lightest and darkest color. Here you will have to understand three things; TS, RS, and AS.

  • TS refers to solar heat gain getting transmitted through fabric and glass

  • RS is for solar heat that gets reflected

  • AS is for solar heat gain absorbed by the fabric

If the fabric is of darker color then the absorbance rate is higher. For instance, if it is a black color fabric then absorbance rate could be as high as 81%. This will make the fabric work like a radiator of heat into your home. Thus, to avoid such a situation what you can do is opt for a lighter color like white that will probably have an absorbance rate of about 14%.

# Glare

  • There will be another factor that you will have to look into, and it will be light transmitted (referred to as TV) by the fabric
  • This factor is used for measuring the amount of glare you will have to bear
  • TV will be the number that will show the percentage of light that gets radiated through your solar shades fabric
  • If this number is higher, then it will mean that more light can pass through the fabric and will result in more glare

As such, if you want to reduce the amount of glare then it will be necessary to select a darker color for your fabric so that more light is absorbed and there is less amount of glare.

Graber Solar Blinds And Shades – Shading Coefficient

Interior Installation | Exterior Installation

Shading coefficient refers to the ratio of solar heat going through fabric and glass. Let us look at the shading coefficient for both interior and exterior installation of solar shades.

Situation #1

Interior Installation
  • If it is a white colored fabric, then it is likely to allow as much as 40% of the solar heat gain to enter your room
  • On the other hand, a black colored fabric will let around 70% of the solar heat gain (SHG) to enter the room
  • This happens because dark colored fabric absorbs light, which gets converted into heat

Situation #2

Exterior Installation
  • The opposite will happen when you have an exterior installation
  • The SHG for white colored fabric will be close to 30% while for a dark colored fabric it would be about 23%

Graber Window Coverings

Since the dark colored fabric will be absorbing the heat on the exterior, the solar heat gain will be less when the exterior installation of Graber window coverings makes use of a darker colored fabric.

# Heat Weldable

Graber Roller Shades

If the fabric of Graber roller shades is heat weldable, then it can be turned (or railroaded) if the window opening is more than 105″. Additionally, if required it can also be seamed using a heat weld to turn it longer than 105″.

Light or Dark Colored Fabric?

Selecting a solar shade with light colored fabric will be the right option when you have small windows in a room and in common areas where you are looking for a brighter and lighter ambiance. On the other hand, if you are looking for glare control and passive solar warming then solar shades with dark colored fabrics will be the right choice.

Let us look at an example to understand the differences between a dark gray and a light gray fabric for your solar shades with an openness factor of 5%

  • The dark gray fabric has a TS of 12, RS of 8, and AS of 80 then same fabrics light gray counterpart will most likely have the configuration of TS 27, RS 57, and AS 16
  • This tells us that darker fabric will be reflecting much less heat and will be absorbing a lot more heat in comparison to the lighter fabric
  • Additionally, if the darker fabric has a TV 21 and the lighter one has a TV 14, then it will mean that the light colored fabric will let more light through

    If all this seems confusing, don’t worry. It’s not an exact science
  • All you need to know is that dark colors reflect less and absorb more heat, while light fabric reflects more and absorbs less heat

Indoor Environment And Safety

Graber Roman Shades

  • Fabrics can emit VOCs (or volatile organic compounds) in the air and are commonly called off-gassing
  • To avoid such a risk, what you will have to do is purchase a fabric material that is Greenguard Gold or Greenguard certified by UL
  • Such certifications will mean that the emission levels from fabric adhere to EPA standards specified for low emission products

Graber Vertical Blinds

  • Certification will also give you the assurance that the fabric you have selected (for your Graber Roman shades or Graber vertical blinds) will not be releasing carcinogens or toxins into your home’s indoor environment
  • Similarly, you may want to look for fabric material that consists of antimicrobial protection which can inhibit the growth of mildew, mold, and bacteria
  • As such, you need to look for certification such as ASTM D 3273, ASTM G22, ASTM 2180, and ASTM 6329 Greenguard bacteria and mold standard
  • Flame retardancy is another safety factor that you need to look into while purchasing solar shades
  • Ideally, you should look for fabrics that meet NFPA 701, ASTM 84, and NFPA 101 standards that are related to flame retardancy

# The Weave

Basket Weave | Twill Weave | Jacquard Weave

Weave plays an important role in improving fabric’s performance. Let us look at the available options:

  • Basket Weave: Since it is a non-directional weave, it will appear the same irrespective of the direction in which the fabric is hung.

  • Twill Weave: It is a type of diagonal pattern which makes it possible to manufacture fabrics which are dark on one side and light on the other.

  • Jacquard Weave: This weave facilitates the use of custom patterns and designs since in this weave each yarn of the loom can be individually controlled.

A Final Note

To conclude, we will say that the selection of the right fabric is important while you purchase solar shades.
