How to Fit Composite Cladding?

February 28, 2025

One excellent method to both protect and enhance the appearance of your walls is to use composite wall cladding. Composite cladding is perfect for renovating your home’s exterior walls because it is long-lasting and visually appealing. To guarantee a stunning and long-lasting installation. We’ll take you through the fundamental procedures required to install composite cladding on your walls.

Materials and Items Needed

The following supplies and equipment must be ready before we begin installing composite cladding:

  • Composite wall cladding panels
  • Measuring tape
  • Level
  • Screws and wall anchors
  • Screwdriver or drill
  • Adhesive (if required)
  • Saw (for cutting panels to size)
  • Pencil
  • Safety equipment (gloves, safety glasses)

Composite Cladding Installation Instructions

Step 1: Measurement and Preparation

Measure the wall’s area that needs to be covered first. Determine the square footage mathematically after taking measurements of the length and width. Invest in enough composite cladding to completely cover this space. Additionally, keep in mind to purchase additional composite cladding in case something goes wrong or needs to be fixed later.

Step 2: Get the Surface Ready

Verify that the walls are dry, clean, and clear of any paint or dirt that might be sticking out. You might need to apply a layer of plywood or another suitable backing material if the wall is uneven. By doing this, the surface will be level and smooth for the cladding to be installed.

Step 3: Creating a Plan for Layout

Plan the arrangement before you begin installing composite wall cladding. Decide on the orientation and arrangement of the panels. Most people install from the bottom up for a clean and organized finish.

Step 4: Setting Up the Initial Panel

At the base of the wall, position the first composite wall cladding panel. Make sure it is completely straight by using a level. If you want to secure the panel in place, you can use wall studs. To keep the panel from shattering, drill holes in it before fastening it.

Step 5: Proceed with Panel Installation

Make sure the next panel is firmly attached to the first panel before adding it. If necessary, use wall studs and screws to distribute them evenly throughout the panel. Repeat the process for the subsequent composite cladding, ensuring that every wall panel fits snugly and is level.

Step 6: Cutting and Trimming

Measure and mark panels when cutting to the end of a row or when cutting to fit around windows and doors. The composite cladding should be trimmed to the correct size and shape using a saw. Wearing safety gear is essential for this phase.

Step 7: Adhesive (if necessary)

Certain composite wall cladding systems could need an adhesive for further security. If so, adhere to the glue and splice the panels together according to the manufacturer’s directions.

Step 8: Perfecting the Edges

To finish the look, trim the edges and corners if needed. These trims also aid in stabilizing the panel edges.

Step 9: Final Check

Once all the composite cladding has been spliced together, take a step back and admire your accomplishment. Verify that every panel is securely fastened, flat, and free of any cracks or damage.

Crucial Details for Composite Cladding Installation

Always make sure the composite wall cladding has space to expand. To accommodate for the material’s thermal expansion, leave a minimum of 8mm between the butt joints at each end of the boards.

The distance between the board’s edge and the adjacent wall, object, or floor should be at least 20 mm. The boards may warp if there is not enough room for expansion, which could nullify the warranty.

Prior to installation, drill pilot holes. To keep the composite material from shattering, use pilot holes that are the right size while screwing it in. The holes in the board should be at least 2 mm bigger than the threads to keep the board from cracking when heated.

Clamps at each end of the board should not be shared. Attach one complete bolt and one complete clip to each end of the plank. It is not appropriate to share clamps between butted ends. Instead, secure the plank ends with a double press.

When putting in composite cladding on the top and bottom, use butt joint strips. Seam strips guarantee adequate air and water flow for vertical installations.

Guidelines for Composite Cladding Storage and Handling

Following these crucial handling, storage, and transportation guidelines will help composite wall cladding maintain its attractive appearance for a long period.

Storage Suggestions

  • Cover the material until it is time to install it to maintain a clean surface. This is especially crucial if it will be kept outside for storage. It will be necessary for you to utilize an impenetrable cover.
  • Establish a support point 500 mm above the ground after making sure all of the composite cladding is level and flat.
  • The stored cladding materials should be secured and separated using battens. To prevent the battens from bending, make sure they are no more than 500 mm apart.
  • Stack such that the battens and bottom supports line up.
  • It is not recommended to stack cladding pallets more than three meters or four pallets high.

Managing Suggestions

  • Avoid tipping or dropping the composite wall cladding materials when unloading them.
  • Carefully lift and lower the boards to remove them from the unit. When moving, make sure the boards don’t slip against one another.
  • Use the ends of the boards to support the composite wall cladding to increase the stability of the boards.
  • During building, avoid dragging or sliding any tools over the planks to avoid damaging them.
  • The boards may get damaged if you set anything, including building debris, on their surface.

You may prolong the appearance of your composite cladding product by adhering to these handling and storage guidelines.

Guidelines for Spacing and Expansion Gaps

It is crucial to make sure that every composite wall cladding conforms with the following clearance and spacing requirements in order to accommodate for the natural expansion and contraction of composite materials as temperatures change:

  • Make sure there is at least 8 mm between butt joints when utilizing boards that are 3.6 meters long. The growing gap between boards should be at least 0.2% of the boards’ length when they are cut or trimmed.
  • When using composite cladding for butt joints, leave a minimum of 20 mm between the ends.
  • There must be a minimum of 20 mm of space between the cladding and any wall or other attachment.
  • Give the bottom border of the cladding panel at least 20 mm of space from the floor.
  • To facilitate water drainage and air circulation, make sure the space below the cladding is at least 38 mm.

How to Install Composite Wall Cladding

Composite wall cladding can be firmly installed using treated timber battens or laminated battens. The following guidelines should be adhered to in order to accomplish a successful installation:

  • To make sure they are sturdy and offer the right support, each compression seam strip component must be joined in at least three locations.
  • Composite slats should not be used for typical building tasks. Composite laths will perform better than other compression seam strips in specific situations, including siding installation.
  • Vents should be at least 38 mm wide to guarantee proper air circulation and to permit rainfall that has penetrated the cladding to drain freely. It will be easier to maintain the necessary space behind the cladding panels if you choose a press-seam strip that is at least 38 mm thick.
  • Make sure to follow BS8417 when handling wooden battens if you choose to use them.
  • Covering the cavity opening with an insect screen is a smart idea to keep insects out of the cavity. This will assist in maintaining the cladding in good shape and keep bugs away.

Installing Support Slats for Siding

To install high-quality, dependable siding, make sure to adhere to the following instructions while installing support slats for composite cladding:

Space and Ventilation

Make that the bracing strips on the wall or other structure are spaced no more than 600 mm apart. This will give the cladding steady, even support.

To allow for air circulation, leave a space behind the cladding that is at least 38 mm wide. Rainwater can drain smoothly and with adequate air movement thanks to this cavity.

Installing a double layer of compression strip construction at the connections between cladding panels might provide further strength. The wall becomes stronger and more sturdy when more compression seam strips are added on both sides.

Bracing Strip Installation

At least 20 mm should separate the first support strip from the ground. Installing the pallet does not need activating it. The support strip is fastened in place with screws. The screws should be no more than 600 mm apart for the best support. Verify that every screw is parallel to the wall. Packing can be employed to guarantee leveling if required.

Construction of Double Slats

The wall panel joints (sometimes called “butt joints”) should have a double slat structure fitted at both ends. The plank joints receive extra support and stiffness from this double-slat technique.

Speak with an Expert Builder

It’s wise to speak with a building expert regarding insulation and vapor barriers for your cladding job. Their expertise can assist you in making sure your installation fits the requirements and building environment.

Guidelines for Composite Wall Cladding Maintenance

Composite cladding will continue to look excellent and endure longer if it is properly maintained. Here are some crucial upkeep pointers:

Cleaning Techniques

Products made of composite wall cladding can be cleaned with a soft bristle brush and soapy water. As an alternative, you can utilize a power washer that has a 1500 psi maximum pressure.

Use a fan nozzle tool and always spray in the direction of the board grain when using a pressure washer. Stay at least 6 inches away from the surface. Use the appropriate cleaner for cleaning.

Grease and Dirt

To avoid dust, grime, and mold accumulation, composite wall cladding may usually be cleaned with soapy water on a regular basis. Although composite cladding products prevent mold growth and discoloration. However, mold stains can still occur in damp or pollen-filled areas.

Spot Stains

Many stains are best removed with soap, warm water, or a home degreaser. Rinse with warm water after promptly scrubbing and soaking the area. To effectively remove particularly difficult stains, you might need to utilize a cleaner designed specifically for composites.

Although it is uncommon, you might need to lightly sand the damaged area with coarse sandpaper (60–80 grit) for certain tenacious stains.

Precautions for Stain Removal

Depending on location and use, cleaned or sanded areas may initially appear lighter. However, they usually return to their previous condition within 8-10 weeks.

Similar to any wood product, composite wall cladding may show “tea stains” or extraction bleed color. This is a transitory stain that will go away on its own with time, so you don’t need to worry about it.

Abrasions and Scratches

Weather will eventually cause abrasions and scratches on the composite cladding’s surface to disappear. Scratches and scuffs can be removed using a wire brush or coarse 60–80 grit sandpaper.

Sand, brush, or remove marks in the direction of the item’s grain. The region will weather and recover in eight to ten weeks following treatment.

Applying Paint and Stain

Composite wall cladding can be painted or stained. However, most composite product makers advise against it. This is due to the fact that composite cladding doesn’t stain over time. In addition, staining could nullify the warranty.

Make sure the cladding’s surface is dry and clean before painting or staining, and give the product time to weather completely. Make sure you adhere to the product’s instructions while applying paint or stain.

These upkeep and care guidelines will help you maintain the excellent appearance of your composite wall covering. This will increase its longevity and improve your outside experience.
