At R-Shield, we are driven by a commitment to deliver innovative, high-quality insulation solutions for the construction industry. As a proud member of the Premier Building Systems family, R-Shield carries forward a legacy of excellence and innovation in building products. Our expanded polystyrene (EPS) and graphite expanded polystyrene (GPS) insulation materials are engineered to meet the diverse needs of modern construction, offering solutions that are versatile, efficient, and environmentally responsible.
Choosing insulation is about more than just performance—it's about long-term reliability. With R-Shield, you’re not only getting a high-performing product; you’re also getting the peace of mind that comes from Premier Building Systems’ 50-year warranty. Unlike other rigid insulations that may see their warranties—and performance—diminish over time, R-Shield’s warranty remains strong, just like its stable thermal values. This combination of proven product performance and robust warranty protection makes R-Shield a dependable, cost-effective choice for any project.

R-Shield is engineered to give you optimal control over your project’s application—from design flexibility and timeline efficiency to material cost management. With R-Shield, you can customize insulation to fit your unique project requirements, helping you keep projects on schedule and on budget. Designed to cover a wide array of applications, R-Shield EPS and GPS insulation products are versatile solutions for both residential and commercial construction needs.
The secret to R-Shield’s superior performance lies in its unique manufacturing process and material composition. Unlike traditional rigid insulations like Polyiso and XPS, which rely on chemical-intensive methods, R-Shield is manufactured using an innovative steam expansion process. This method not only minimizes environmental impact by eliminating harmful blowing agents, but also ensures exceptional material consistency and strength.
Through steam expansion, the EPS and GPS beads in R-Shield insulation are expanded to form a lightweight yet robust cellular structure, consisting of over 90% air. This structure provides stable thermal performance that won’t degrade over time, while also being highly moisture-resistant and vapor-permeable. By using steam rather than chemicals, R-Shield products reduce their global warming potential by up to 10 times and eliminate ozone-depleting emissions.
This controlled expansion process results in a sustainable, recyclable product with a minimal environmental footprint. From raw material to finished product, R-Shield’s steam expansion ensures that each insulation panel is manufactured to meet stringent quality standards, giving contractors and builders a high-performing, environmentally responsible insulation option they can trust. This results in:
R-Shield doesn’t just insulate—it enhances the construction process by providing structure, predictability, and superior moisture management:
Predictable Performance: With R-Shield’s precision-cut panels, builders and contractors know exactly what to expect. This predictability simplifies installation, reduces unexpected adjustments, and keeps project timelines and costs in check, creating a smoother, more streamlined construction experience. R-Shield’s EPS and GPS materials also ensure long-term stability, meaning the insulation will maintain its structural integrity and thermal efficiency for decades.
Structural Integrity: R-Shield EPS provides excellent compressive strength and durability, ideal for direct-to-deck and other structural applications. Unlike fiber-based insulations that may shift or compress under load, R-Shield maintains its form, making it suitable for high-performance applications such as roofs, walls, and below-grade uses.
Moisture Resistance: One of the standout advantages of R-Shield’s EPS insulation is its superior moisture management compared to other rigid insulations like XPS. In XPS, water tends to become trapped within the fiber structure, with only 2-3% of the moisture retracting slowly over time. This gradual retraction can lead to long-term degradation of thermal performance. In contrast, R-Shield’s EPS beads allow moisture to move in and out freely, enabling rapid drying and preserving the insulation’s stable R-value. This quick-release feature prevents moisture buildup, ensuring that R-Shield maintains its effectiveness in wet conditions and minimizes the risk of mold or water damage that could compromise the insulation’s longevity.
High Vapor Permeance: R-Shield’s high vapor permeability allows moisture to escape rather than remain trapped within the insulation. This ability to “breathe” makes it an excellent choice for wet climates or areas prone to high humidity, where vapor-permeable insulation can enhance the building’s durability and energy efficiency.
By combining predictable installation and long-term thermal stability with superior moisture resistance, R-Shield ensures that projects remain on track and protected, giving builders confidence in both performance and longevity.
R-Shield EPS and GPS insulation products come with a range of benefits that set them apart:
R-Shield is more than just insulation; it's a complete solution for those seeking high performance, reliability, and environmental responsibility in their building projects. From simplifying complex roofing systems to maintaining stability below ground, R-Shield’s products offer a trusted choice that builders and contractors can rely on.
