What is a Moire?

According to the Merriam-Webster Dictionary, a Moire is “an independent usually shimmering pattern seen when two geometrically regular patterns (such as two sets of parallel lines or two halftone screens) are superimposed especially at an acute angle”. If you can visualize that from the definition, congratulations. You are pretty word-centric.

How about a video to just show you what a moire is more simply? Yeah, me too! After you watch the video, we will talk about a couple of points that are relevant.

Ways to Avoid Moire

When you have two patterns that are sheer, you have to be careful that that patterns don’t match too closely. When they match, they create this shimmering effect that we call a moire. When you watch the video, or just at the screenshot, you see these huge waves of competing fabrics. To be honest, the camera makes it worse than it really is, but you need to be aware of this issue, before you purchase.

One of the ways I mentioned in the video to avoid the Moire issue is by removing the exterior insect screen. This is very possible on many of your windows. If you open certain windows for ventilation, then obviously you will keep the outside bug screens on those windows. This technique will help you have a less obstructed view.

Another way to avoid a moire is by choosing a different product, or a variance of the type of fabric that is typically done for screen shades. When choosing with your window fashion expert, a good designer will hold the fabric up to your windows and show you how it affects the look.

I’ll write about this concern another time because there are other products that create a moire. This blog was specifically about solar screen shades, whether roller shades or Roman shades.
