Polyiso roof insulation is likewise produced at high density to end up being a much-specified cover board. Cover boards safeguard the roof assembly from roofing traffic, mechanical abuse and hail. These roofing system cover boards are resistant and lightweight. The Polyisocyanurate Insulation Manufacturers Association (PIMA) does impressive work in looking into the current patterns in polyiso advances and is a great assistance for the insulation industry.

High-Density Extruded Polystyrene (XPS) Roofing Insulation R = 5 With an R-value of around 5 per inch, extruded polystyrene (XPS) is produced utilizing an extrusion process to produce closed-cell rigid foam insulation with polystyrene polymer. Many producers add a color to the formulation to include an unique colouration, usually pink, green or blue to identify the product brand name.

For industrial roofing, it is most typically specified for Inverted Roof membrane Assembly (IRMA) or Protected Membrane Roofing (PMR) systems. Extruded polystyrene is usually ranked in the middle of cost vs. R-value in terms of cost/benefit evaluation of flat roof products. It is susceptible to solvent-based adhesives and hot asphalt, and its usage in PMR systems needing ballast can make structural weight of the assembly a problem.

With Insulated Metal Roofing Panels, The Future Of Roofing Insulation Is  Here

High-Density Expanded Polystyrene (EPS) Roofing Insulation R = 4. 6 Expanded polystyrene (EPS) is made from the very same base polystyrene resins as XPS, but the manufacturing procedure is different, resulting in beads that are formed and cut into different sizes and shapes or formed. High-density items have an approximate R-value of 4.

Contractors like to set up EPS as it can be cut easily to fulfill site conditions, and it is light-weight. In theory, it has a more steady R-value with time as there are no chemical blowing agents that can outgas. There are no existing research studies that can verify this quality. EPS has several drawbacks, nevertheless.

In addition, foot traffic on the roofing can damage the material. 6. Glass Fiber and Mineral Fiber Batts and Panels R = Variable by Maker The commercial roofing industry phased out rigid fiberglass two-by-four panels as single-ply roof systems became a larger share of the marketplace.  Check Here For More , fiberglass was not suggested for EPDM, PVC or TPO systems.
