There is no single best option. Whether you choose open lattice, fascia boards, or full board cladding, the cost is generally similar from one solution to another. It is mainly a matter of style: which option best matches your decking and the overall look of your outdoor space?

Keep in mind : closing the sides of a patio is often a more significant investment than the surface decking itself. It is therefore a good idea to plan for it early in your project design.

No matter which finish you choose, one key point remains essential: the underside of your patio must stay ventilated. Good airflow protects the structure against moisture and extends the lifespan of your installation.

Yes, and it’s one of the most practical benefits of a well-finished patio. By finishing the perimeter with fascia panels, boards, or lattice, you can turn the space under your deck into storage for patio furniture, tools, and outdoor accessories. It is even possible to integrate doors or drawers on the sides for convenient access and a clean finish.

What you need to know about waterproofing: Dekavie boards are not 100% waterproof. About 15 to 20% of rainwater can seep through the gaps between boards. To limit moisture, make sure your boards are installed in the direction of the drainage slope so water naturally flows outward. This helps keep the underside of the patio drier.

For most storage items, this level of water resistance is more than sufficient. If you need greater protection, a membrane or gutter system such as Goberco can be installed under the decking to direct water outward.

In all cases, it is important to maintain good ventilation under the patio. Proper airflow prevents moisture buildup and extends the lifespan of your structure. Our HDPE lattice is an excellent option for combining enclosure, storage, and ventilation at the same time.

Finishing a patio skirt is not just about installing cladding, it is a three-step process that, when done properly, delivers a clean, durable result with no surprises.

Build the supporting structure. Before any cladding is installed, a solid frame must be built between the ground and the deck structure. This frame will support and hold the finishing panels.

Install a membrane. Once the structure is in place, the front of the frame is covered with a membrane before installing the cladding. This step protects the top of the joists from moisture and extends the lifespan of the entire structure. We offer membranes suited for this application.

Install Dekavie cladding. Fascia, boards, or lattice, our recycled plastic finishing components are used to cover the structure for a weather-resistant, low-maintenance, and visually appealing result. They are available in the same colors as our decking boards for a perfectly coordinated look.

No matter which finish you choose, remember to allow space for ventilation. A well-ventilated underside is a longer-lasting structure.

Closing in the underside of a patio helps prevent animals from nesting underneath and reduces the accumulation of leaves and wind-blown debris. It also gives the deck a much more finished look and can turn the space underneath into a storage area.

Several materials can be used for a patio skirt:

• PVC panels
• treated wood
• decorative lattice
• HDPE plastic boards
• perforated metal

The best way to hide a patio structure is to install a patio skirt or a finishing panel system around the deck. This installation conceals the beams, joists, and posts while giving the terrace a clean and professional appearance.
