StackFence’s 4 ft Storm Grey semi-private composite fence pairs cool woodgrain WPC boards with rust-resistant black aluminum posts. Its dual design builds two open airflow spaces into each panel — a sleek, contemporary look with horizontal lines that also lets wind pass through instead of catching it like a solid fence, so it holds up better through Missouri weather without the upkeep wood demands.
Each 4 ft × 6 ft panel uses interlocking wood-plastic composite (WPC) boards on a simplified rail system, so it installs faster and holds its look season after season. At a lower 4 ft height, it’s a great fit for front yards, garden borders, and open boundary lines where you want definition without closing in the view.
Available as a complete panel set you can install yourself, or supplied and installed through StackFence and our approved Missouri installer partners.

Why Choose a Storm Grey Semi-Private Composite Fence Over Wood
Missouri summers are humid, spring brings heavy rain, and winters cycle through freeze and thaw — the exact conditions that make a wood fence rot, warp, cup, and split, and that’s before the yearly cost of staining and sealing just to keep it presentable. Composite is built to shrug that off and hold its shape and color year after year.
- No annual staining, sealing, or repainting
- Resists rot, warping, and splitting in Missouri humidity
- Holds its color and shape through heat and freeze/thaw swings
- Fade-resistant surface built for hot, sunny summers
How the Semi-Private System Is Built
A premium composite fence designed around a sleek, contemporary look and long-term performance.
Dual Airflow Design
Two open spaces built into each panel let wind pass through, so it stands up to gusts better than a solid fence — and they give it a clean, modern banded look.
Storm Grey Woodgrain Boards
Solid WPC boards with a realistic wood-grain texture and clean horizontal lines, in a cool, contemporary Storm Grey tone.
Black Aluminum Posts
Powder-coated aluminum posts and caps that resist rust and corrosion — strong and modern, and a crisp contrast to the Storm Grey boards.
Interlocking Rail System
Boards lock into top and bottom rails for a straight, secure, faster build.
Low-Maintenance Material
No staining or sealing — a rinse with the hose keeps it looking new.
What’s in the 4 ft Panel Set

Frequently Asked Questions
What does “semi-private (dual)” mean?
Semi-private means it isn’t a solid wall — each panel has two open airflow spaces rather than full coverage, so it feels lighter and less boxed-in. “Dual” refers to those two open spaces, which also let wind pass through instead of catching it like a solid fence.
Is a 4 ft fence tall enough for privacy?
A 4 ft fence is designed more for defining a boundary, adding curb appeal, and light screening than for full privacy. If you want more height and screening, we also offer this style in a 6 ft panel.
Does it hold up in wind?
Because the two openings let air pass through the panel instead of pushing against a solid surface, a semi-private fence like this generally handles wind better than a full-privacy wall. For very exposed sites, ask us about post spacing and setting depth.
Is composite really maintenance-free?
Not completely — we prefer “low-maintenance.” There’s no staining, sealing, or repainting like wood. Occasional cleaning with a hose or mild soap and water is usually all it needs.
Can I install it myself?
Yes. The interlocking boards and simplified rail system are designed for a straightforward install, and many homeowners do it themselves. We also offer professional installation if you’d rather not.
How many panel sets will I need?
Each set covers one 6 ft-wide section. Share your approximate footage and any gates through the form on this page and we’ll help you work out the count.
Is there a warranty?
Yes — the composite boards carry a 20-year limited material warranty, and installed projects also include a one-year workmanship warranty. Ask for written warranty details with your quote.
