Deck privacy option compared. Frosted glass railing, tinted glass, privacy picket, standalone screens, and wind walls. What blocks sightlines, what blocks wind, what blocks both, and what it costs.
This article is part of our complete Aluminum Deck Railing guide.
You want privacy on your deck. Maybe the neighbours are 15 feet away. Maybe the street has a clear sightline to your patio furniture. Maybe you just want to sit outside without feeling watched. There are a lot of ways to get privacy on a deck, and they range from a $30 bamboo roll from the hardware store to a fully engineered glass privacy wall system. The difference between them isn't just aesthetics. It's whether the solution is structural, code-compliant, weather-resistant, and permanent, or whether it's temporary and decorative.
We manufacture aluminum and glass railing systems at our facility in Aldergrove, BC. Privacy projects are a growing part of what we supply, particularly in dense residential areas across the Lower Mainland, the Okanagan, and the Pacific Northwest. The Christina Lake, BC project installed by Grand Forks Deck and Rail is one of the best examples of how privacy railing works in practice: one property using frosted privacy glass, clear infinity glass, and standard picket on different sections of the same deck, each chosen based on what that section faces.
Privacy railing vs standalone privacy screens
The first decision is whether your privacy solution is part of the railing or bolted on top of it.
Privacy railing means the railing itself provides the privacy. Frosted glass panels, tinted glass panels, or closely spaced privacy pickets replace the standard clear glass or open picket infill. The privacy is built into a system that's engineered, tested (our posts are Intertek tested to 315 lbs), and code-compliant as a guard under the National Building Code of Canada and the International Building Code. It does two jobs at once: safety barrier and privacy barrier.
Standalone screens are separate structures attached to or placed near the deck. Lattice panels, bamboo reed rolls, outdoor curtains, horizontal slat screens, planter walls. These add privacy but they're not structural. They don't replace your railing. They don't meet guard code. They add cost on top of whatever railing you already have. And most of them degrade faster than engineered aluminum and glass because they weren't designed for permanent outdoor exposure.
If you already have railing and just want to add some screening, a standalone option might make sense. If you're building new or replacing old railing, building the privacy into the railing system eliminates an entire layer of cost and maintenance.
Frosted glass: privacy without losing light
Frosted glass is the most popular deck privacy screen option we supply. The glass is acid-etched during manufacturing, which diffuses light so you can't see detail through the panel. You get brightness without visibility.
At Christina Lake, Mike Victory (our Director of Sales) describes the privacy sections: "Standard railing, which is glass, privacy glass. We have a two and a half inch post, and it transitions to a regular 1.72 post." The 2.5-inch posts are used on the privacy screen sections because they support the double glass mid-rail system, which extends higher than standard railing for additional screening. The regular 1.72-inch posts handle the standard railing sections on the same deck.
Frosted glass also shows fingerprints and dirt less than clear glass. On a railing that gets touched constantly, that's a practical advantage beyond privacy.
Tinted glass: partial privacy with glare control
Tinted glass in grey, bronze, or green reduces visibility without fully blocking it. You can still see shapes and movement through tinted glass, but detail is reduced. It's not full privacy the way frosted is, but it softens the sightline enough for many situations.
The added benefit is glare reduction. On south-facing and west-facing decks, tinted glass cuts the harsh afternoon sun that makes clear glass uncomfortable. The Metropolis towers in Newark, NJ use tinted glass panels across two multi-storey buildings, where the tint provides partial privacy while complementing the building's architecture.

Privacy picket: the affordable alternative
Privacy picket uses closely spaced aluminum pickets to block sightlines without using glass at all. It's the most affordable privacy option and doesn't require the careful handling that glass does during installation.
The Powell River, BC project installed by Modern Powell River shows privacy picket alongside regular picket and infinity glass on the same property. Mike describes it: "There's a mixture of product shown here, where you have privacy picket. You have regular picket, and then you have a transition to infinity." Each section uses the infill type that matches what it faces.
The trade-off with privacy picket is that it blocks more light than frosted glass and doesn't provide wind protection. Wind passes straight through the gaps between pickets. If wind exposure is a problem on your deck, glass is the better choice.
Wind walls: when you need more than railing height
Standard railing is 36" or 42" tall. That blocks a sightline when you're standing, but wind comes over the top. Our double glass mid-rail system extends the glass barrier above standard railing height, creating a wind wall that also functions as a privacy screen.
The Christina Lake project uses this system on the sections facing the neighbouring property. Mike calls it "a wind wall, but also it's a privacy screen." It's the same aluminum post and glass panel system as standard railing, just taller. For more on glass railing in wind-exposed and elevated applications: Glass Balcony Railing.
Mixing privacy options on one deck
The best privacy projects we see don't use one solution everywhere. They mix infill types based on what each section of the deck faces.
Clear glass on the view side. Frosted glass on the side facing neighbours. Privacy picket on the section facing the driveway where you don't need light transmission. Standard open picket on the section facing the backyard where privacy isn't a concern. Same posts, same powder coat colour (AAMA 2604, Tiger Drylac and AkzoNobel), same mounting hardware. Different infill where it matters.
Our systems are designed for this. The posts, top rails, and base plates are cross-compatible across all infill types. A dealer can quote a mixed configuration without any custom engineering. The 3D Railing Designer lets you visualize different combinations before ordering.
How to choose the right deck privacy screen
Choose frosted glass if you want full privacy, wind protection, and light. It's the premium option. $80 to $150 per linear foot for glass component railing.
Choose tinted glass if you want partial privacy with glare reduction. Works best on sun-exposed decks where light management matters as much as screening.
Choose privacy picket if you want privacy at the lowest cost and don't need wind protection. $50 to $100 per linear foot for aluminum picket.
Choose a wind wall if standard railing height isn't enough. The double glass mid-rail system extends the barrier for maximum wind and privacy protection.
Mix them if different sections of your deck face different conditions. This is what most of our dealers recommend, and it's what the Christina Lake and Powell River projects demonstrate.

Frequently asked questions
What is the best privacy screen for a deck?
Frosted glass railing provides the most privacy while keeping light and blocking wind. Privacy picket is the most affordable option. Tinted glass provides partial privacy with glare reduction. For the best results, mix infill types based on what each section of the deck faces.
Can you add privacy to existing deck railing?
If your existing railing is aluminum, your dealer may be able to swap the infill panels from clear to frosted glass or from standard picket to privacy picket without replacing the posts. If you're replacing old wood or iron railing, building privacy into the new system is more cost-effective than adding a standalone screen on top.
Does frosted glass railing block wind?
Yes. Glass panels, whether clear, frosted, or tinted, create a solid windbreak. Picket railing does not block wind because of the gaps between pickets. If wind protection matters, glass is the right choice.
What is a deck privacy wall?
A deck privacy wall is a glass panel system that extends above standard railing height, typically using a double glass mid-rail configuration. It functions as both a wind wall and a privacy screen. The panels are frosted or tinted for privacy and engineered for the wind loads at the specific installation height.
Can you mix clear and frosted glass on the same deck?
Yes. Our systems use the same posts and mounting hardware across all infill types. Clear glass, frosted glass, tinted glass, standard picket, and privacy picket can all be used on the same deck with the same colour and post style.
