WPC Exterior Wall Cladding Installation Guide

This guide explains how to install our 2.6m WPC Exterior Wall Cladding Boards and matching trims. It is intended as general guidance for competent DIY installers and tradespeople.

WPC expands and contracts as temperatures change, so correct ventilation, support spacing and expansion gaps are essential. The cladding must not be fixed directly against the wall or installed so tightly that the boards cannot move.

Important: Every building and installation is different. Check that the wall, fixings and supporting framework are suitable for the intended application. For large elevations, exposed locations, buildings subject to fire regulations or installations above ground-floor level, consult a qualified installer or building professional.

Before installation

Store the boards correctly

Store the boards:

• Flat and fully supported
• Off the ground
• In a dry, well-ventilated area
• Away from direct heat
• Protected from impact and scratching
  

Do not store the boards leaning against a wall for extended periods, as this may cause them to bow.

Allow the boards to acclimatise near the installation area before fitting. Some composite-cladding manufacturers recommend approximately 48 hours, although the exact requirement depends on the product and conditions.

Check the wall

The supporting wall must be:

• Structurally sound
• Clean and reasonably level
• Free from loose render, crumbling masonry and vegetation
• Capable of supporting the battens and cladding
• Properly weatherproofed before the cladding is installed
  

The WPC cladding is a decorative rainscreen finish. It should not be relied upon as the building’s primary waterproof barrier.

Any required breathable membrane, flashing, cavity barriers or insulation should be installed before the battens and cladding.

Plan the layout

Before fixing anything, determine:

• Whether the boards will run vertically or horizontally
• The position of corners, windows, doors and other openings
• Where full and cut boards will be placed
• The location of starter trims and finishing trims
• How joints will be supported
• How ventilation will enter and escape from behind the cladding
  

Measure the wall carefully and plan the layout to avoid leaving a very narrow cut board at the final edge.

Batten orientation

The battens must run in the opposite direction to the cladding boards.

• For vertical cladding boards, install the battens horizontally.
• For horizontal cladding boards, install the battens vertically.
  

This provides regular support across the back of every board.

Where horizontal battens are used, the cavity must still allow water to drain and air to circulate vertically. Counter-battens or suitable drainage and ventilation breaks may, therefore, be required.

Batten spacing

As a general starting point, install battens at a maximum of approximately the following:

• 300mm to 400mm centres
  

Also position battens:

• At both ends of every board
• Around windows and doors
• Along internal and external corners
• Behind every board joint
• Wherever trims require support
• Around lights, cables, vents or other penetrations
  

Published guidance varies considerably by WPC profile, with some systems specifying approximately 300mm centres and others allowing up to 500mm. Your final batten spacing should therefore be confirmed with the board manufacturer or supplier, particularly for exposed exterior elevations.

Use additional battens in areas subject to increased wind loading.

Ventilation cavity

Do not install the cladding directly against masonry, render, insulation or membrane.

Maintain a continuous ventilated cavity behind the boards. A cavity of approximately 20mm to 25mm is commonly required for exterior composite cladding systems.

The cavity should:

• Remain open at the bottom and top
• Allow moisture to drain away
• Allow air to circulate behind the boards
• Be protected against insects where necessary
• Not be blocked by adhesive, sealant or insulation
  

Use suitable ventilated profiles or insect mesh where required, without preventing airflow.

Expansion gaps

WPC moves naturally as temperatures rise and fall. Never install the boards tightly against walls, trims, roofs, paving, window frames or other fixed objects.

Unless your product-specific technical information states otherwise, allow approximately the following:

• 5mm between board ends or butt joints
• 5mm to 8mm around fixed objects, trims and openings
• A suitable gap at the top and bottom of the installation
• Additional movement allowance across particularly long elevations
  

Several composite-cladding systems specify an end-to-end expansion gap of at least 5mm.

Do not fill required expansion gaps with rigid adhesive or sealant.

Expansion requirements vary according to board composition, board length and installation temperature. Confirm the final gap with your supplier before publishing it as a fixed warranty requirement.

Installation instructions

1. Mark the installation area

Use a tape measure and spirit or laser level to mark:

• The bottom of the cladding area
• The position of every batten
• The location of corners and openings
• The finished position of trims
  

Make sure the starting line is completely level. Any error in the first board will become more noticeable as the installation continues.

Where the cladding begins close to the ground, leave enough clearance to prevent standing water, soil, vegetation or splashback from constantly contacting the boards.

2. Install the battens

Position the first batten at the edge of the installation area and secure it to the wall using appropriate fixings.

Continue fitting the remaining battens at consistent centres.

Check that:

• Every batten is straight
• The faces of all battens sit in the same plane
• The framework is level and plumb
• All board ends and joints will be supported
• The wall fixings penetrate into a suitable structural substrate
• The ventilation cavity remains continuous
  

Use packers where necessary to create an even fixing surface. Do not force flexible boards over an uneven framework.

Leave small breaks where required for drainage and ventilation rather than creating enclosed sections that can trap water.

3. Fit corner and perimeter trims

Install any trims that need to sit behind the cladding before fitting the first board.

Depending on the design, this may include:

• External corner trims
• Starter trims
• L trims around windows and doors
• Bottom or side finishing profiles
  

Fix trims into the supporting battens rather than only into the cladding boards.

Keep all trims straight and allow the required expansion clearance between the board ends and the inside of the trims.

External corner trims

Use external corner trims where two clad walls meet at an outside corner.

Make sure:

• Both sides of the corner are properly battened
• The trim is straight and plumb
• Each adjoining board remains fully supported
• The boards have room to expand inside or alongside the trim
  

L trims

Use L trims to:

• Finish exposed board edges
• Frame windows and doors
• Create a defined perimeter
• Cover suitable transitions between cladding and adjoining surfaces
  

Where possible, cut trim corners using neat mitre joints.

Starter trims

Use starter trims at the beginning of the cladding layout or where the product profile requires an enclosed starting edge.

Set the starter trim perfectly level, as it controls the alignment of the boards that follow.

4. Measure and cut the first board

Measure the required length at more than one point, as walls and openings may not be perfectly square.

Mark the board and cut it using a fine-toothed blade suitable for composite material.

Support the board on both sides of the cut to prevent vibration or damage.

Wear suitable eye and respiratory protection. WPC cutting dust should not be inhaled.

After cutting:

• Remove loose dust and swarf
• Check that the cut is square
• Test-fit the board
• Confirm the required expansion clearance
  

5. Install the first cladding board

Place the first board into the starter trim or against the marked starting position.

Check that it is:

• Level or plumb, depending on orientation
• Correctly positioned
• Fully supported by the battens
• Not resting on the ground
• Not tightly trapped between trims
  

Fix the board through the designated fixing flange or concealed fixing area.

Where screws pass through the WPC:

• Pre-drill the fixing holes
• Make the pilot hole slightly larger than the screw shank where movement is required
• Position the screw centrally in the fixing area
• Drive the screw straight
• Do not overtighten
  

The screw head should hold the board securely without crushing, distorting or clamping the profile so tightly that it cannot move.

Do not fix through the visible slatted face unless the system specifically requires it.

6. Install the remaining boards

Engage the next board with the interlocking edge of the previous board.

Push it into position carefully, ensuring that:

• The joint is fully engaged
• The board remains straight
• The slatted spacing is consistent
• The ends remain supported
• Expansion clearance is maintained
  

Fix the new board into every supporting batten through its concealed fixing flange.

Continue across or up the wall, checking the alignment every few boards. Do not wait until the final board to correct a developing level or alignment problem.

A rubber mallet may be used gently with a protective block. Do not strike the board directly with a metal hammer.

7. Form board-end joints

Where two boards meet end to end:

• Support each board end independently
• Use two adjacent battens where required
• Do not leave either board end unsupported
• Maintain the required expansion gap
• Stagger joints where appropriate for the chosen layout
  

Never bridge a butt joint with a single screw positioned too close to both board ends.

For the neatest finish, plan joints so that they align consistently or are positioned in less prominent areas.

8. Clad around windows and doors

Install additional battens around the full perimeter of openings.

Before cutting the boards:

• Measure each opening carefully
• Allow for the finishing trim
• Allow the necessary movement gap
• Check that any sill flashing can drain freely
• Make sure the cavity is not blocked
  

Cut the boards neatly and finish the exposed edges using matching L trims or the appropriate perimeter profile.

Do not obstruct drainage channels, window weep holes, vents or air bricks.

Water must be directed away from the opening using properly installed flashing or weatherproof detailing. Decorative trims alone should not be treated as waterproof flashing.

9. Install the final board

Measure the remaining space and cut the final board to width where necessary.

Do not force an oversized board into the gap.

Fit the board while maintaining the appropriate expansion clearance, then secure it into the supporting battens.

Where the fixing flange has been removed during cutting, the final edge may need to be secured using the appropriate trim or another manufacturer-approved concealed fixing method.

10. Fit the finishing trims

Install the remaining external corner, L or finishing trims.

Check that:

• All cut edges are neatly covered
• Corners are straight
• Mitred joints close neatly
• Fixings are concealed where possible
• Drainage and ventilation openings remain clear
• The cladding is not tightly pinched by the trim
  

Remove all cutting dust, protective film and installation debris.
