Metal standing seam roof systems incorporating PlastiSpan insulation provide an energy efficient option for a wide range of applications. The exterior metal surface can include a variety of profiles and colors to suit many architectural requirements and the system offers the added advantage of installation at any temperature.
Modern metal roof designs incorporate a number of different design concepts. The standing seams are often roll-formed on the job site and include a sealant placed in the seam. The roof system is held down with clips that are incorporated into the standing seams and have a slotted hole for attachment to provide for expansion/contraction of the roof assembly.
The use of PlastiSpan insulation board within the metal roof assembly provides a uniform insulation layer with the required thermal resistance. The insulation can be laid over a light gauge steel deck incorporating a thermal barrier or vapour barrier where required. An air barrier is recommended in the roof system in order to avoid the movement of air through the system. Standing seam roofs are applied to sloped roof construction where the required slope is provided by the roof structure itself.
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.
