When it comes to roofing insulation, not all rigid boards are created equal. The right roofing insulation board can make a significant difference in energy efficiency, comfort and even the lifespan of your roof. But with so many options available, varying in thickness, material and thermal performance, how do you choose the best one for your project?
At Benchmark Foam, we specialize in Expanded Polystyrene (EPS) roofing insulation designed for many applications.
Differentiating Roofing Insulation
Material Matters
Roofing insulation boards come in different materials, each with unique benefits:
- EPS (Expanded Polystyrene): Lightweight, cost-effective, naturally moisture and mold resistant. It’s compatible with most roofing systems and maintains stable thermal performance (R-value).
- XPS (Extruded Polystyrene): Boasts high compressive strength and initial high R-value but blowing agents used during manufacturing diffuse over time, taking R-value with it.
- Polyiso (Polyisocyanurate): Offers a higher R-value per inch but at a higher cost.
EPS strikes the best balance between performance, ease of installation and affordability for many projects.
Keys to Thermal Efficiency
R-value reflects how well any insulation material resists heat flow. The higher the R-value, the greater the insulating power. However, it must be ensured that the material used fits the lifespan of the structure, as not all materials are created equal in regards to the stability of their R-value. While EPS may require slightly more thickness to achieve comparable R-value, it has a proven, stable R-value, ensuring its thermal properties.
EPS provides excellent R-value at a lower cost in comparison to other materials, making it a smart choice for many projects.
Matching Insulation to Roof Systems
Not every roof insulation material will work with every system. While the primary function of a proper roof insulation system is to keep the heat where you want it or reduce heat transfer. A critical part of maintaining the roof system is to direct water away from the roof so as to not negatively impact the performance of the roof system.
EPS can be produced flat and custom-cut to match your roof system and ensure water is dispelled from the roof, for nearly any system, including flat, sloped and metal roof systems.
