Composite fences

Composite fence

Get the appearance of wood without the maintenance it demands. We install board fences on the South Shore in LM Woodgrain composite or LM Karbon HDPE, two durable, stable solutions well suited to Quebec's climate.
Grey composite fence with black posts along a modern house
Composite and HDPE reproduce the character of wood without behaving like it. No warping, no cracking, no boards to replace. The panels hold their line and their colour after several freeze-thaw winters.

A clean finish to structure your landscape
Boards slide into the frame through a U-Track system, with no visible hardware. One continuous line, with no exposed screws breaking the rhythm of the panels.
A stable, rigid frame
The boards are installed on aluminum or steel posts, with corrosion-resistant hardware. The whole system stays straight and solid for the long term.
Repairable board by board
Each board slides in and out individually. A damaged board is replaced on its own, without taking the section apart.

Two boards, one wood finish with no maintenance

Two boards, one extruded aluminum frame, and the same 20-year warranty. The difference comes down to the material. For a fully private, architectural contemporary aluminum option, also see our Zen aluminum fences.

FAQ

Frequently asked questions about composite fences

Answers to the most common questions about our composite and HDPE board fences.
Free quote
What composite fence heights are available?

Panels are available in 60 inches, 72 inches, and 96 inches (5, 6, and 8 feet), depending on the desired privacy and your property layout.

What's the difference between LM Woodgrain composite and LM Karbon HDPE?

LM Woodgrain is a composite board (wood fiber and polymer) with a true-to-grain wood texture, available in four tones. LM Karbon is an HDPE board (high-density polyethylene) that doesn't absorb moisture, won't rot, and resists impacts even below freezing, available in eight colours. Both mount on the same aluminum frame and carry a 20-year warranty.

What colours are available?

LM Woodgrain composite comes in four tones, Black, Stone Grey, Forest Brown, and Sand. LM Karbon HDPE comes in eight colours, including white. Physical samples are available on request.

Can composite handle Quebec winters?

Yes. Composite doesn't warp or crack under freeze-thaw cycles, and HDPE doesn't absorb moisture and resists impacts even in deep cold. On a rigid aluminum frame, both retain their alignment and colour after several winters.

What warranty comes with a composite fence?

Composite and HDPE boards are covered by a 20-year limited warranty against manufacturing defects, including cracking and peeling. Several financing options are also available.

Do I need a municipal permit to install a composite fence?

Most municipalities require a permit to install a fence. We recommend checking the requirements with your city before starting the project.
