Description

Roofers have trusted this color for centuries; patios are just catching up. A custom slate curtain brings that same sober, weathered-stone authority to a pergola — dark enough to screen the neighbors at lunch, gray enough that the space underneath still feels like daytime.

Slate Sunbrella drapes belong with modern farmhouse builds, board-and-batten walls, and blackened-steel hardware, and they give pale hardscape the contrast it's usually missing. Layer lighter gray cushions against them and the whole bay looks composed.

Why Choose This Curtain?

Exactly the Panel Your Bay Ordered

Every Sunbrella Cast Slate outdoor curtain is sewn to your submitted dimensions, so coverage runs edge to edge and the hem strikes a single line across the structure.

Mid-Dark That Stays Mid-Dark

Dark grays betray coating-dyed fabric by going pale and patchy. Slate's heathered strands carry pigment all the way through, weathering evenly under the 5-year colorfast warranty.

The Sensible End of Dramatic

Slate hides grill haze and pollen the way dark colors do, but its heathered mid-value dodges the heat-soaked, cave-dark feel of true black. Splash beads off the highly water-repellent finish; the fabric resists staining and water spots.

Fabric Information

Slate holds the useful middle ground of dark gray — enough weight for privacy and presence, enough light left in it to stay clearly gray, never black. The Cast heathering mixes close-toned strands so the surface carries the soft mottling of split stone. Like every color we sew, it's solution-dyed: pigment enters the liquid acrylic before the strand exists, and Sunbrella warrants the result colorfast for 5 years.

Your Sunbrella Cast Slate outdoor curtain is cut to the width and drop you provide, seamed twice over in UV-resistant outdoor thread, and treated with a fluorocarbon finish that keeps it highly water-repellent while the open weave sheds humidity.

Frequently Asked Questions

Think wet slate roof: unmistakably dark, unmistakably gray. It's several steps lighter than black, and the heathered surface reflects just enough light to show its texture. Closed panels read substantial without turning a bay into a dark room.
Yes — Slate is the medium-dark of the pair. Charcoal presses close to black; Slate keeps more visible gray and shows its heathering more openly. If you're torn, Slate is the safer daytime choice and Charcoal the more dramatic evening one.
That's its core argument. The opaque weave blocks sightlines completely, but the mid-dark tone and open structure of a curtained bay keep ambient light bouncing through. You get a screened lunch table, not a sealed booth.
Life. Flat dark fabric can look industrial at scale; Slate's mingled strands give big panels the mottled character of natural stone, which reads softer and more expensive. The variation also disguises dust and water marks between rinses.
Noticeably. Drawn across a west bay, the dense mid-dark weave knocks low-angle glare down to a comfortable dimness while the rest of the structure stays open and bright. It's the difference between squinting through dinner and enjoying it.
Rarely. Droplets bead up on the highly water-repellent finish and roll away before minerals can dry into rings, and the heathered mid-tone camouflages the few that remain. The fabric resists staining and water spots by design.

Great waterproof material and made to spec.

The material is good quality. The fit is not good, despite their website requiring a number of different measurements. Part of me suspects the website photos were generated by AI, as they’re almost too perfect.

Worth the money

I just received my order. I am very happy with the product.
It fits perfectly. Please let the people who created the cover know; they did a great job.
Here's a picture. I hope the material will last a long time against the sun. Just keep in mind that it does take 4-6 weeks so be very patient unlike me. haha. totally worth it

The tie downs at the corners were not long enough to latch together. Otherwise the build quality was very high.

Highly recommend!

I ordered a right arm love seat cover, left arm love seat cover and an ottoman cover in the higher end fabric. With a discount code, all 3 were a little over $300. The covers are perfect and the quality of the fabric is…..well, let’s just say it’ll probably outlive me! They’re very heavy duty and totally waterproof. Craftsmanship is excellent.

Customer service was A+. I had questions about measuring and some concerns about shipping. I used the chat option for questions about measurements and it was a REAL person, not a bot. He was friendly and personable. They also contacted me to verify some things about my measurements. When I contacted both sales and customer service via email with a question, they responded within hours. They’re constructed in another country and it took about 6 weeks from order to delivery. The delay was FedEx customs.

Bottom line, they are excellent covers at an extremely fair price that fit perfectly, will last forever and are a very friendly, responsive, competent company to work with.
