Wood-Look, Aluminum Slat, or Fire-Resistant Steel Fence: Which Fits?

For a modern backyard, choose composite wood-look (myRedwood) when you want full privacy with a finished look on both sides, aluminum slat (myAir) when you want airflow and an open horizontal design, and fire-resistant steel (myFireGuard) when you're in a fire zone or want certified fire performance. The useful part is that all three are infill options on the same Modern Yard post platform, so you're choosing a look and a performance profile, not three different fences.
At a glance: which backyard fence material fits
Material | Best for | Quantified signal |
myRedwood composite | Full privacy, wood-look | Both-side finish, 25-year warranty |
myAir aluminum slat | Airflow, sightlines | Open horizontal slat design |
myFireGuard steel | Fire-zone and WUI | ASTM E84 Class A, 120 mph wind rating |
Read down the "best for" column to find your priority, then use the decision checks below to confirm the fit before you order.
What should you check before choosing a backyard fence material?
Start with three questions. How much privacy you need, whether your property has a fire-zone requirement, and how the fence should read from both sides. Those decide the material faster than any feature list, because each Modern Yard infill is built for a different answer. The checklist below structures the decision so you're matching the material to the site rather than to a sales claim.
What to check | Why it matters | Strong signal |
Privacy level | Full screen vs. airflow changes the material | Both-side-finished panel for full privacy |
Fire-zone status | WUI areas may require certified materials | ASTM E84 Class A, CFSC Vendor List |
Both-side appearance | Shared boundaries need matched faces | Good neighbor fence in the California sense |
Wind exposure | High-wind sites need structural strength | Steel system, 120 mph wind rating |
Long-term maintenance | Coastal and humid sites stress finishes | TriShield protection, 1500+ hr salt spray |
Gate and lock match | A mismatched gate undercuts the look | Matching gate frame, pre-drilled for the lock |
Modern Yard is a modular fence and gate system platform built for professional contractors, fence dealers, and lumber yards across the United States, and each material above runs on the same myPost universal post. That's why the decision is about infill, not about committing to a separate system.

When does composite wood-look make sense?
Choose myRedwood composite when you want the warmth of wood with full privacy and a finish that matches on both sides. It's the option for a private backyard or a shared boundary where both you and your neighbor see a finished face. In California, where the "good neighbor fence" standard is most commonly referenced, myRedwood qualifies because both sides carry the same board pattern.
Privacy. Full screen, no gaps, finished both sides.
Look. Wood grain appearance without the maintenance cycle of natural wood.
Boundary use. Works as a good neighbor fence in the California sense.
The composite system seats into the same post groove as the other infills, so the gate and posts come from the same platform. You can see board options on the wood-look composite fence page. It's backed by a 25-year limited warranty, so there's no need to estimate how many years the finish holds; the warranty states the coverage.
When does aluminum slat make sense?
Choose myAir aluminum slat when you want airflow, partial sightlines, and a clean horizontal-slat look rather than a solid screen. It's the open-design option, so it fits front yards, garden edges, and modern backyards where you want light and breeze through the fence line.
myAir is not a full-privacy good neighbor fence. The slats read similarly from both sides, but the design leaves gaps by intent, so it shouldn't be described as a both-side-finished privacy panel. If full screening is the goal, composite or steel is the better match; if airflow and sightlines are the goal, the slat design is the point. See the modern aluminum fence page for the slat profiles.
Airflow. Open horizontal slats let air and light through.
Design. Architectural horizontal lines for a modern look.
Privacy. Partial, by design, not a full screen.
When does fire-resistant steel make sense?
Choose myFireGuard steel when your property is in a fire zone or WUI area, or when you want certified fire performance with full privacy. It's a both-side-finished steel privacy panel, so it works as a good neighbor fence in the California sense while carrying fire-resistant performance the other materials don't.
The Modern Yard FireGuard Series is fire-resistant, tested to ASTM E84 Class A, and listed on the California Fire Safe Council Vendor List, which makes it a code-relevant option for WUI and fire zone projects. The fire-resistant powder coating releases moisture as it heats, which reduces temperature, smoke, and flame spread across the panel surface. It's fire-resistant, not fireproof, and the distinction matters. The rating describes tested flame-spread and smoke behavior, not an absolute guarantee.
The steel system is also engineered to withstand wind loads rated up to 120 mph and uses the TriShield triple-layer protection system, combining powder coating, internal foam sealing, and structural drainage for long-term corrosion resistance, with the coating rated to 1500+ hours of salt spray testing. That makes it the pick for high-wind and coastal sites as well as fire zones. See the fire-resistant steel fence page for panel details.

Which material fits which backyard scenario?
The cleanest way to decide is by matching the scenario to what matters most on that site. Each row below pairs a common backyard situation with the material that fits and the reason.
Use case | What matters most | Why this material fits |
HOA backyard, shared boundary | Matched look both sides | myRedwood, both-side finish, 25-year warranty |
Fire zone or WUI property | Certified fire performance | myFireGuard, ASTM E84 Class A |
Front yard or garden edge | Airflow and sightlines | myAir, open horizontal slat |
Coastal or high-wind site | Corrosion and wind strength | myFireGuard steel, 120 mph, 1500+ hr salt spray |
Pool surround needing privacy | Full screen, finished both sides | myRedwood or myFireGuard privacy panel |
Because all three run on the same post platform, a backyard can mix them on one continuous system. A fire-zone property might run myFireGuard along the exposed boundary and myAir across a garden edge, with the gate and lock shared across both. The modular connector system supports flat ground, slopes, and corners with the same posts, so mixing materials doesn't mean mixing systems.
Does the gate and lock stay consistent across materials?
Yes. Whichever infill you choose, the gate frame accepts the same infill as the fence, so the gate carries the same board or panel pattern. The welded aluminum gate frame ships pre-drilled for the lock, and the aluminum hinges are packaged with the frame and installed on-site. That keeps the gate from reading as a separate add-on regardless of the material.
The myLock combination lock works the same across all three systems. It's a battery-free mechanical lock with 665,000 combinations, sequential code entry for enhanced security, and a Universal Fit that handles both left-hand and right-hand gates without swapping parts. One lock SKU covers any of the three materials and either gate orientation.
How does a system approach change the comparison?
Comparing wood-look, aluminum slat, and steel usually means comparing three separate product lines from different suppliers, each with its own posts, gates, and hardware. On the Modern Yard system, the comparison narrows to the infill, because the post, rail, gate, and lock logic stays the same underneath. That's a simpler decision and a more consistent backyard.
The whole system is backed by a 25-year limited warranty and distributed through national and regional partners including Master Halco, BMD, and Golden State Lumber, so any of the three materials is supported by local inventory and dealer service. Installation videos and PDF manuals for each system are published on the installation guides page, so you can verify the build for your chosen material before ordering.
Match the material to your site, then confirm the gate
Pick by priority first. Choose composite for full wood-look privacy, aluminum slat for airflow, and fire-resistant steel for fire-zone and high-wind sites. Confirm your fire-zone status and both-side appearance needs against the checks above, then verify the matching gate size and the shared lock in the same system. If your backyard has more than one need, remember the materials mix on one post platform, so you don't have to force a single choice. Your authorized dealer can confirm the infill, gate, and lock against your layout before you order.
