SECA Th-Wo Treated Double Rhombus is a type of wooden cladding material that has been treated with a special process called thermal modification to improve its durability and stability. The “Th-Wo” stands for “Thermal Wood”, which refers to the fact that the wood has been heated to a high temperature to alter its chemical and physical properties.

The double rhombus shape refers to the shape of the individual boards, which have two parallel faces that are angled on both sides to form a diamond shape. This shape allows for easy installation and creates a modern, streamlined look when the boards are fitted together.

The thermal modification process involves heating the wood to a high temperature in a low-oxygen environment. This causes changes in the wood’s cell structure and chemistry, making it more resistant to decay, insects, and moisture. The process also changes the color of the wood, giving it a darker, more uniform appearance.

SECA Th-Wo Treated Double Rhombus is commonly used for exterior cladding on buildings, but it can also be used for interior applications such as wall paneling or ceiling tiles. One of the benefits of using this type of wood is its increased stability and resistance to warping, splitting, and cracking. The thermal modification process also reduces the wood’s tendency to expand and contract in response to changes in temperature and humidity.

SECA Th-Wo Treated Double Rhombus is available in a range of sizes and finishes, allowing for a variety of design options. It is a sustainable building material, as it is made from renewable wood sources and the thermal modification process does not involve the use of harmful chemicals.
