Q Can XPS foam boards be used in combination with other insulation materials?
A
Yes, XPS foam boards can be used in conjunction with other insulation materials, such as fiberglass, to achieve higher R-values and improve overall thermal performance.
While XPS foam boards have a closed-cell structure that provides some degree of moisture resistance, they are not entirely waterproof. However, they are highly resistant to water absorption and will not rot or degrade when exposed to moisture.
XPS foam boards are commonly used for insulating roofs, walls, floors, and foundations in residential, commercial, and industrial buildings. They are also utilized in cold storage facilities and various other construction projects.
