Loglap cladding T&G (tongue and groove) is a type of exterior siding that mimics the appearance of log cabin walls. It features boards with interlocking edges, allowing for a seamless, weather-tight fit. The T&G design provides a clean, traditional look while enhancing insulation and reducing drafts. Typically made from timber, it is used to give buildings a rustic charm and offers both durability and ease of installation.
