How Does a Cordless Day Night Cellular Shade Work?

A day night cordless cellular shade is basically two cellular shades stack on top of each other, allowing you two different fabrics in one.

Moreover, the shade will be filtering the daylight for avoiding glare and heat. This means that the room will remain bright and light while at the same time you will be able to maintain a certain level of privacy.

What to look for while purchasing cellular shades that block heat?


Shading Coefficient | Openness Factor | Type of Fabric

By checking certain aspects you will be able to purchase the right shade that provides better performance in terms of blocking of heat. Let us look at what those aspects are.

Shading Coefficient

One of the important aspects you will have to look into while buying cellular shades will be their ability to reflect heat.

This can be evaluated by what is known as “shading coefficient”. For instance, if any specific window treatment is able to reduce heat in the 75-85% range then the window treatment has a shading coefficient that is in the .25-.15 range.

Thus, while making a purchase you will have to look for shades that have lower shading coefficient so that you have the assurance that it will be able to better reflect heat.

Openness Factor

Openness factor is the number that tells us about the tightness of weave for solar day and night shades.

If the openness factor is high then you will be able to easily see through your shades. But, on the negative side, you will be letting in more heat as well as UV light.

As for example, if you purchase a shade that has an openness factor of 1% then it will be able to block almost 99% of UV light. This way you will be able to conserve more energy but at the same time, you will sacrifice your outside visibility.

Thus, if blocking out heat and UV rays is important for you then you will have to select a shade that has lower openness factor. The light filtering and blackout fabrics of cellular shades generally do not have an openness factor, meaning there are no openings in the fabric and they will block 100% of UV through the fabric.

Type of Fabric

When your main aim is to keep the heat out of your home, a crucial aspect you will have to look into will be the type of fabric to select.

Let us look at the positive and negative aspects of light and dark colored fabrics so that you can make the right choice while purchasing shades for your home.

Positives and Negatives of Dark Fabrics


  • Dark fabrics are able to better control glare due to the fact that the fabric is able to absorb more light.
  • You will also have better outside visibility since dark fabrics will reduce glare during daylight hours (applies to sheer fabrics).


  • Since they absorb more heat compared to light fabrics, you will gain less in terms of reduction of heat.

Positives and Negatives of Light Fabrics


  • Compared to darker fabrics, they are able to better reflect heat, which in turn will help in reducing cooling costs.



  • You will not have as clear outside visibility during daylight hours (for sheer fabrics).
  • Reduction in glare will be slightly less than what darker fabrics are able to achieve.



To conclude we will say that cellular shades certainly prove to be effective in blocking the heat out and should be your first preference when your main aim is to reduce the amount of heat that comes into your home through windows.
