Cladding with planks and weatherboards involves specifications focused on material choice, dimensions, profiles, finishes, and installation methods. Common materials include timber, fibre cement, and vinyl, each offering different benefits such as natural aesthetics, durability, and low maintenance. Profiles like shiplap and bevelled edge provide various visual effects. Finishes can be painted, stained, or textured, enhancing appearance and protection. Installation can be horizontal, vertical, or diagonal, using different fixing methods. Key considerations include fire ratings, durability against rot and pests, weather resistance, and sustainability, with options for eco-friendly and recyclable materials. These specifications ensure optimal performance, durability, and aesthetic appeal for building exteriors.
