Hybrid roofing insulation systems, and why they matter

Two is frequently better than one. One measly scoop of ice cream hardly seems enough when compared with two heaping servings of your favorite flavor. Or in a team setting, where combining forces can lead to bigger wins.

Hybrid roofing insulation is no exception, combining the benefits of multiple types of insulation in one high-performance system. When blending polyisocyanurate (polyiso) rigid foam insulation’s high R-values with cost-effective expanded polystyrene (EPS) rigid foam insulation, contractors can save money while complying with code-required R-values. As an added benefit, EPS offers the highest R-value per dollar, and the R-Value remains consistent over time. This provides the two-in-one roofing solution with a stable, reliable foundation.

While hybrid roofing insulation can come in a variety of combinations, the result is particularly noteworthy when EPS and polyiso team up:


EPS taper and polyiso hybrid systems

Insulfoam’s tapered EPS insulation combined with polyiso flat board insulation creates an ideal hybrid roof insulation system that saves you time and money on the roof. Our tapered EPS insulation is available and customizable up to 40” thick in one layer, less layers means less adhesive and less time installing insulation boards on the roof. When you need to build up a slope on the roof to facilitate positive drainage, this hybrid insulation dynamic duo combines the best of both products to give you a labor and cost saving solution for any tapered roof application.

EPS and polyiso hybrid insulation solutions simplify the jobsite and accelerate installation, therefore creating wider profit margins for savvy building professionals.


EPS flute-fill for metal retrofit roofs with polyiso over-top

EPS and polyiso work just as well in metal roof applications, where EPS can be used as flute-fill, fitting snugly between seams, and has a layer of polyiso covering it. Insulfoam Flute-Fill can be factory-taper-cut, square-cut or profile-cut to fill metal roofs’ spaces or standing seams perfectly. When every minute counts on the jobsite, eliminating the task of field-cutting insulation saves valuable time.

After installing EPS flute-fill, construction teams have a gap-free and uniformly smooth surface to place the polyiso over-top. According to the roofing systems manufacturer, Carlisle Syntec Systems, polyiso “provides energy-efficient solutions for buildings in any region and climate, as well as outstanding return on investment and significant energy savings.” These performance outcomes tailor well with EPS insulation’s nearly air-tight composition and metal roof’s ability to help sustain lower utility bills and lessen environmental impacts.
