How much does the sunscreen fabric open?

Have you found the term “openness” in silk fabrics, but you don’t know what this means? Of course, if you’ve finished this article, it’s because you don’t know what the degree of openness on the screen means. The screen fabric is a technical fabric designed to control solar radiation and is made of PVC-coated polyester thread. These types of fabrics are perfect for making roller blinds, vertical blinds, and custom Japanese blinds.

This type of fabric is mainly used for:

Increase privacy without giving up external vision.
It helps save energy and reduces the use of heating or air conditioning.
Filters sunlight and reduces glare.
Protect the fading of furniture parts (eg fabrics, furniture, upholstery, carpets, etc.) in the house.
They retain the original color of their choice for a long time.
It is prepared by interweaving thousands of fine threads together to form a uniform woven fabric. When we talk about openness, we mean the separation that exists between these threads, allowing more or less light to pass from the outside to the inside. Also called open factor.
That is, the larger the interval between the interwoven threads, the greater the degree of opening or opening, and the closer the weft or interval of these threads, the lower the degree of opening of the mesh fabric.

In short, the effect of the screen on transmitted solar radiation depends on two main factors:

Tissue thickness
The density of the tissue, depending on how open it is
Tissue color
Screen fabric openness:
In order to make you clearer, we show you the mesh fabrics with different opening degrees among the most demanding mesh fabrics on the market and their effects.

5%: Medium height outward visibility and medium light input.
3%: average outward visibility and low light input.
1%: Low external visibility and low light input.
10%: High outward visibility and highlight input.
0%: total light blocking and visibility inside and outside.

These values are standard values, but you should know that as we pointed out earlier, the color of the fabric also affects visibility. For dark colors, the visibility is greater, and for light colors, the opacity is greater.

Screen fabric and products:
Screen fabrics have become an increasing demand for different types of products due to their many advantages: energy saving, filtering, and visibility control. This type of fabric is mainly used for shutters, risers, Japanese panels, awnings or canvas.
