What is rtd sheathing?

RTD sheathing is a type of rigid thermal insulation that is commonly used in construction to provide thermal and moisture protection for buildings. RTD stands for "rigid thermal drywall," which refers to the material's ability to provide both thermal insulation and act as a sheathing material for walls.

RTD sheathing is typically made of a rigid foam material, such as expanded polystyrene (EPS) or extruded polystyrene (XPS), which has a high R-value and helps to reduce heat transfer through the building envelope. It is used in both residential and commercial construction projects to improve energy efficiency, reduce heating and cooling costs, and create a more comfortable indoor environment.

In addition to its thermal insulation properties, RTD sheathing also serves as a moisture barrier, helping to prevent water infiltration and damage to the building structure. It is often installed on the exterior walls of a building, underneath the siding or exterior finish material.

Overall, RTD sheathing is a versatile and effective building material that helps to improve the energy efficiency, durability, and longevity of a building.
