What is cladding, and which type is right for your building?

Cladding is a term that architects and builders use daily, but one that many homeowners encounter properly for the first time only when planning a build or renovation. Put simply, cladding is the material applied to the exterior, and sometimes interior, surface of a building's structure. It is one of the most consequential choices you will make for any project, influencing how the building looks, how it performs, and how much maintenance it requires over its lifetime.
This guide explains what cladding is, outlines the main types available, and examines why WPC (Wood Polymer Composite) cladding has become an increasingly popular choice for residential, commercial, and mixed-use developments.
What is cladding?
Cladding is an outer skin or layer applied over a building's primary structure. It is typically not load-bearing; rather, it serves a range of protective and aesthetic functions. Depending on the product chosen, cladding can provide weather protection, thermal insulation, moisture resistance, acoustic performance, and UV shielding. At the same time, it defines the visual character of a building.
As shown in this overview of cladding in construction, cladding systems range from simple horizontal board applications to complex rainscreen arrangements. What they share is a fundamental purpose: to protect the structure behind them while contributing to the building's visual identity.
The main types of cladding
Cladding comes in a wide range of materials, and the right choice depends on your budget, aesthetic goals, performance requirements, and the environment the building is located in.
Timber cladding
Timber cladding is one of the most traditional options and remains popular for its natural warmth and variety of profiles, including horizontal, vertical, shiplap, and tongue-and-groove formats. However, it requires consistent maintenance, typically painting, oiling, or staining every two to three years, and is vulnerable to moisture damage, rot, and insect infestation without proper treatment.
Fibre cement cladding
Fibre cement is a durable and fire-resistant option that can be finished to resemble timber. It handles moisture well and is relatively low-maintenance. The trade-off is an industrial quality in its appearance that does not suit all architectural styles, and its weight can add complexity to the installation process.
Metal cladding
Steel and aluminium cladding are commonly specified for commercial, industrial, and contemporary residential projects. They are extremely durable and come in a wide range of profiles and finishes. However, they can feel cold and hard in residential settings, and certain metals require specific coating regimes to prevent corrosion in humid or coastal environments.
WPC composite cladding
WPC cladding has grown significantly in popularity over the past decade. It combines the visual warmth and texture of natural timber with the performance characteristics of polymer, resulting in a product that resists moisture, UV degradation, rot, and insects without the same maintenance investment as solid timber. It is suitable for both interior and exterior applications, giving specifiers considerable flexibility.
Why architects and builders are choosing WPC cladding
The shift towards WPC cladding among professional specifiers reflects a straightforward calculation: the combination of low maintenance, strong aesthetics, and environmental credentials is difficult to match with other materials. For residential projects, WPC reduces the ongoing cost and effort of building upkeep. For commercial projects, it delivers a consistent appearance over time that aligns with the longer replacement cycles typical of larger buildings.
Additionally, the sustainability profile of products like those from Acacia Composites, made from invasive bush in Namibia using a CO2-neutral process, addresses a growing requirement from clients and planning authorities to demonstrate responsible material sourcing.
The Acacia Composites cladding range
Shiplap cladding
The shiplap cladding is a precision-extruded WPC board designed for clean, overlapping installations. The shiplap edge detail creates a seamless visual finish while allowing for natural expansion and consistent alignment. At 138 x 18 mm, it is suitable for interior and exterior use and comes in woodgrain and brushed surface profiles. Available colours include Camelthorn, Charcoal, Hazelnut, and Cinnamon.
ThermoCell wall cladding
The ThermoCell wall cladding is designed for projects where thermal performance is a priority alongside visual appeal. The insulated construction improves the energy efficiency of the building envelope, making it a strong specification choice for projects targeting improved thermal ratings or reduced running costs.
Interior and exterior cladding applications
One of the practical advantages of WPC cladding is its versatility. Externally, it performs well on facades, boundary walls, pergolas, and covered outdoor structures. Internally, it works as a feature wall finish, a paneling solution for commercial reception areas, or a durable surface treatment in moisture-prone rooms. Because WPC cladding does not require painting, sealing, or oiling, it simplifies the build process and reduces the trades required to complete a project.
Choosing the right cladding for your project
The right cladding depends on several factors: the aesthetic you are aiming for, the environment the building is located in, the performance requirements you need to meet, and the maintenance budget available. WPC composite cladding is particularly strong for projects that require a natural timber appearance, a long service life, and minimal upkeep.
