What is the best fabric for roller shades?

What fabric should I choose?
SunCoast Blinds Breaks It Down

Picking out new window treatments can feel a little daunting, right? But if you’ve landed on the clean, modern look of roller shades, you’re on the right track. The next, and most important, decision is choosing the right fabric. At SunCoast Blinds, we’re an independent studio, which means we get to handpick the very best manufacturers for each product. This freedom ensures you’re always getting top-tier quality and performance.

That’s why when it comes to our roller shades, we’ve teamed up with Mermet.

Mermet’s Story: An American-Made Legacy

So, who is Mermet? Well, their story actually started in France back in 1951. They began as a company that wove custom textiles, and their dedication to innovation quickly made them a leader in sun control fabrics. By 1986, they decided to bring their expertise to the United States, setting up a production facility in Cowpens, South Carolina. For more than two decades, they’ve been proudly manufacturing their vinyl-coated fiberglass sunscreen fabrics right here in America. When you choose a Mermet shade, you’re not just getting quality; you’re supporting American-made craftsmanship.

Why Fiberglass Beats Polyester Every Time

You might find a lot of roller shades out there made from polyester, but we believe fiberglass is in a league of its own. Here’s why.

First off, think about dimensional stability. Unlike polyester, fiberglass fabric won’t stretch, shrink, or twist. It’s completely unfazed by the sun’s intense heat, so your shades will always hang perfectly flat and true in the window—no warping or sagging over time. This makes fiberglass fabric perfect for custom-shaped shades and even for large, tension-held applications. Plus, this reliability means we see fewer quality issues and less need for those frustrating call-backs.

Another huge benefit is how lightweight fiberglass is. It’s much lighter than polyester, and this makes a big difference. For example, it allows for a smaller tube and a reduced motor size, which gives your motorized shades a sleeker, more discreet look. Because of the lighter load, you can also couple more shades together on a single motor. And if you have manual shades, you’ll notice they require much less effort to pull down.

Finally, the fiberglass yarn itself gives you a crisper, clearer view. The precise weave and dimensional stability of the fabric ensure your view to the outside is sharp and unobstructed, without the fuzzy distortion you can get with other materials.

The Secret of Color and Opacity

The color and opacity of your fabric can dramatically change both the look and feel of your space. Here’s a quick guide:

• Darker shades are excellent for view-through. They reduce glare and allow your eyes to focus on the outdoor scenery, making it feel like the shades aren’t even there.
• Lighter shades, on the other hand, offer superior protection from heat. They reflect more sunlight away from your windows, which helps keep your home cooler and can even lower your energy bills. The trade-off is that they also let in more light, so they might not be the best choice if you’re trying to darken a room.

But what if you want the best of both worlds? Mermet’s innovative KOOLBLACK® collection is a game-changer. It’s a patented technology that gives you the excellent view-through of a dark shade with the heat-reflecting performance of a light shade. It’s a brilliant solution for getting both style and function.

Our Guide to Opacity

At SunCoast Blinds, we help you find the perfect opacity for each room:

• For public spaces like living rooms, we often recommend a 5% openness fabric. This lets you enjoy your view even when the shades are down, while still giving you great sun control.
• If you need a bit more privacy but still want natural light, a 1% or 0.5% openness shade is a great compromise. It blocks a lot of the view from the outside while still allowing a soft, diffused light to come through.
• And for bedrooms or media rooms where you need to block out the light completely, room-darkening shades are the way to go. They’re a must-have if you’re sensitive to morning light or if you work late and need to sleep during the day.
