Single Ply Roofing
PlastiSpan® insulation board can be used in combination with most types of single ply membranes. Single ply roofing systems offer the advantages of rapid installation and lightweight construction.
Proven Performance
Various single ply roof assemblies incorporating PlastiSpan insulation board have been tested for compliance with requirements for fire rated roof assemblies. These roofing systems have many years of proven performance in both new and maintenance roof construction.
Plasti-Fab’s EPS insulation is an excellent choice for roofing applications due to its long-term thermal resistance and performance qualities. With R-values ranging between 3.75 per inch to 4.7 per inch depending on the product used, it is a cost-effective thermal insulation that provides increased energy efficiency within the structure.
Installation Methods
Single ply roofs may be installed loose laid and ballasted, fully or partially adhered to the substrate, or mechanically fastened. Installation can be over a single layer of flat or sloped PlastiSpan insulation or multiple layers of insulation to provide any thermal resistance required. The attachment of the insulation will be influenced by the base requirement of the single ply membrane to be installed.
