Perforated Wallcovering.

Selection.

 

An experienced building professional familiar with the condition of the specific building, local conditions, and the characteristics of wallcovering should be consulted to determine if perforated wallcovering is right for your application. If your building professional determines that a permeable interior wall system is appropriate, interior walls (particularly older walls) should be tested for permeability prior to installation of perforated wallcovering.

While perforated wallcovering will maintain many of the functional qualities of conventional vinyl wallcovering, perforated wallcovering will not be as cleanable, durable or protective as conventional unperforated wallcovering and, due to its higher permeability, will not prevent liquid or vapor moisture originating from the interior of the building (e.g., bathrooms, kitchens, etc.) from going through the wallcovering into the wall and wall cavity. Excellent cleanability/scrubability characteristics as well as protecting walls from interior liquid or vapor moisture intrusion, are important requirements in many applications.

Neither perforated, nor any other type of wallcovering, will prevent mold or other moisture related damage if a wall or wall cavity is subject to moisture accumulation. If moisture is present for a sufficient period of time, mold will form regardless of whether the wall surface treatment is paint, perforated wallcovering or other material. Prompt correction of moisture sources is always required. Building maintenance must always include actions necessary to prevent the development of moisture accumulation sources as well as routine inspections for and prompt corrective action if moisture accumulation is found in a wall or wall cavity.
