The Off-Gassing Myth: Why KORE’s EPS Insulation is a Safe and Reliable Choice.
At KORE, we believe that peace of mind should come standard with your insulation. That’s why our Expanded Polystyrene (EPS) insulation is designed to deliver more than just thermal performance—it also promotes a healthier indoor environment.
One question that can arise when choosing insulation is the process of off-gassing, but with KORE EPS, there’s good news: off-gassing simply isn’t an issue. In this blog, we’ll explain what off-gassing is, why it matters, and how our EPS insulation stands out as a clean, safe, and dependable option for your project.
What is Off-Gassing?
Off-gassing is the release of gases—typically Volatile Organic Compounds (VOCs)—from materials like paints, adhesives, furniture, and some types of insulation. These emissions can affect indoor air quality and, in some cases, lead to health issues like headaches, irritation, or dizziness.
The great news? KORE EPS insulation is an inert, stable material that does not emit harmful gases, making it a smart choice for homes, schools, and commercial spaces alike.
Why KORE EPS is a Safe, Emission-Free Insulation Solution
We’ve built our EPS insulation to deliver on safety, comfort, and long-term performance. Here’s why:
-
Chemically Stable & Inert
KORE EPS is made from expanded polystyrene beads that are chemically stable and do not break down, which means no Volatile Organic Compounds (VOCs) are released into the air over time. The result? Consistently clean indoor air quality, year after year.
-
Free from Formaldehyde & Plasticisers
Our EPS is 100% free from formaldehyde, plasticisers, and other chemical additives commonly found in other insulation types. You can feel confident knowing that your building materials are working with—not against—your indoor environment.
-
98% Air, 2% Polystyrene
EPS is composed of mostly air—98%, in fact—with only 2% polystyrene. Thanks to its simple and safe composition, there are no complex chemical reactions or emissions that could result in emissions over time.
-
Maintains Thermal Performance
While some insulation types, such as PIR, may lose thermal efficiency over time due to off gassing of chemical blowing agents, KORE EPS holds its performance steady. It maintains its thermal resistance for the lifetime of your building, delivering long-term energy efficiency.
-
No Curing or Drying Required
Unlike spray foam insulation, which can emit gases during curing, KORE EPS is ready to go the moment it’s installed. There’s no waiting, no chemical phase, and no emissions—just immediate, reliable insulation.
-
Certified for Indoor Air Quality
KORE EPS insulation meets industry standards for indoor air quality. Whether you’re building a Passive House, retrofitting for energy efficiency, or simply improving comfort, you can count on KORE EPS to deliver clean performance without compromise.
Comfort without Compromise
When you choose KORE EPS insulation, you’re choosing a solution that’s safe, stable, and built to last. Free from off gassing and harmful chemicals, our EPS delivers consistent thermal performance, supports a healthier living environment, and aligns with sustainable building goals.
So, if you’re looking for insulation that offers peace of mind, long-term energy savings, and a positive impact on indoor air quality, KORE EPS is the clear choice.
