Leaking Roof Prods Paper Mill to Switch Insulation Systems

When the original insulation installed in the built-up roofing system on the Powell River Number 11 Paper Machine Building at Pacifica Papers, Inc. failed, a replacement needed to be found. As with most pulp and paper plants, Powell River's Number 11 paper machine operates in a hostile, high-humidity environment, placing severe demands on the performance of the roof and roof insulation systems. With its resistance to high internal humidity levels, compressive strength and dimensional stability key concerns, FOAMGLAS^® cellular glass insulation was selected for the re-roofing project. FOAMGLAS^® Insulation's moisture resistance, dimensional stability and high compressive strength allow it to provide a firm, stable base for modified bitumen, built-up, or adhered elastomeric membrane systems. If the membrane is punctured, water cannot penetrate the closed-cell structure of FOAMGLAS^® Insulation as it can with permeable insulating materials.
