SECA T&G Sib. Larch Double Rhombus is a type of cladding made from Siberian Larch wood. The “T&G” stands for tongue and groove, which is a jointing system used to fit the boards together. The “Double Rhombus” refers to the shape of the boards, which are designed to overlap each other to create a diamond pattern.

This type of cladding is often used for external walls of buildings, as it provides a durable and attractive finish. Siberian Larch wood is known for its durability and resistance to decay, making it a popular choice for outdoor applications. The tongue and groove jointing system also helps to create a tight seal between the boards, which helps to prevent water penetration and reduces the risk of rot.
