Additional Information

Cladding boards are durable exterior building materials designed to cover and protect the walls of a structure. They come in various materials such as metal, wood, vinyl, or composite, offering both aesthetic appeal and functional benefits.


  • Durable Materials: Our cladding boards are crafted from high-quality materials, ensuring longevity and resistance to weather elements.
  • Versatility: Available in a variety of styles, colours, and finishes to suit diverse architectural designs and preferences.
  • Easy Installation: Designed for hassle-free installation, saving time and labour costs during construction or renovation projects.
  • Low Maintenance: Requires minimal upkeep, making it an ideal choice for busy homeowners or commercial property managers.
  • Weather Resistance: Engineered to withstand harsh weather conditions, including UV exposure, rain, snow, and temperature fluctuations.

How It Works:

Cladding boards serve as an external layer for walls, providing an additional barrier against moisture, wind, and other environmental factors. They are installed onto the exterior surface of a building, typically over a moisture barrier or insulation layer, using nails, screws, or adhesive. Once installed, they effectively shield the underlying structure from damage while enhancing its visual appeal.


  • Enhanced Protection: Protects the underlying structure from moisture infiltration, mould growth, and structural damage, prolonging its lifespan.
  • Improved Energy Efficiency: Helps to regulate indoor temperature by providing additional insulation, reducing heating and cooling costs.
  • Aesthetic Appeal: Enhances the curb appeal of buildings with a stylish and contemporary look, increasing property value.
  • Increased Durability: Adds an extra layer of defence against impact, scratches, and other physical damage, maintaining the integrity of the exterior walls.
  • Sustainable Solution: Some cladding materials are eco-friendly and recyclable, contributing to sustainable construction practices and environmental conservation efforts.
