Dow Chemical Thermax
Thermax Metal Building Board provides both insulation value and an interior finish system for interior walls in metal buildings. Thermax insulation board is fire rated for exposed applications in metal buildings and installs quickly in walls and ceilings – inside and outside of purlins, trusses or bar joints. Board insulation is also used in standing seam metal roof applications. Boards are lightweight and can be sawed or cut with a knife. In order to meet fire rating specifications, the surface of the insulation at all joints must be continuously sealed with tape or with a joint closure system. R-values can be found within each product information sheet below.
