Types of Polystyrene Insulation We Offer
Expanded Polystyrene (EPS)
Expanded Polystyrene (EPS) is a durable, cost-effective insulation material with closed-cell structure, offering high thermal performance and moisture resistance. EPS is available in various grades, with each grade offering specific thermal conductivities and compressive strength to suit different applications.
Grades of EPS Insulation
-
EPS70: Suitable for general-purpose applications such as cavity walls and underfloor insulation, offering a compressive strength of 70 kPa and a thermal conductivity of approximately 0.038 W/m·K.
-
EPS100: Ideal for slightly higher load-bearing requirements such as lightweight concrete floors, with a compressive strength of 100 kPa and improved thermal performance.
-
EPS150: Recommended for more demanding applications like floor insulation in high-traffic areas, with a compressive strength of 150 kPa.
-
EPS200: Typically used in commercial and industrial applications, EPS200 provides a compressive strength of 200 kPa, suitable for heavy-duty floor insulation.
-
EPS300 to EPS500: High-density grades with compressive strengths ranging from 300 to 500 kPa, used in applications that require superior load-bearing capabilities, such as industrial floors and infrastructure projects.
White vs. Grey Polystyrene
Polystyrene insulation is available in two main types: white and grey EPS. While both provide excellent insulation, grey EPS contains graphite particles that reflect and trap heat, giving it up to 20% better thermal performance than white EPS. Grey polystyrene is ideal when seeking maximum thermal efficiency with thinner profiles, while white EPS remains a versatile, affordable choice for a wide range of applications.
Key Benefits of Polystyrene Insulation
-
Thermal Performance: With thermal conductivities as low as 0.031 W/m·K for high-grade grey EPS, polystyrene insulation effectively reduces heat loss, maintaining comfortable indoor temperatures year-round.
-
High Compressive Strength: Different EPS grades offer specific load-bearing capacities, with compressive strengths ranging from 70 kPa (EPS70) up to 500 kPa (EPS500), making EPS suitable for both residential and industrial applications.
-
Lightweight and Easy to Install: Polystyrene insulation is lightweight, easy to handle, and can be easily cut to fit, making it ideal for both DIY and professional projects.
-
Cost-Effective Solution: EPS insulation is an affordable option that delivers excellent thermal and structural performance, offering great value.
Frequently Asked Questions (FAQ)
What is EPS insulation best used for?
EPS insulation is lightweight, cost-effective, and used in a variety of applications including floors, walls, and roofs. Different grades provide tailored compressive strength for varying load requirements.
What’s the difference between white and grey EPS insulation?
Grey EPS contains graphite particles that enhance thermal performance by up to 20% compared to white EPS, making it ideal for applications where higher insulation performance is required in thinner profiles.
Can EPS insulation be used for underfloor applications?
Yes, EPS70 and EPS100 are commonly used for underfloor insulation in residential and commercial buildings, providing effective thermal resistance and compressive strength.
What EPS grade should I choose?
The choice of EPS grade depends on the load-bearing requirements of your project. For standard wall insulation, EPS70 may be sufficient, while floors in high-traffic areas may require EPS150 or higher. Contact our team for specific recommendations at 0300 303 4578 or sales@insulationuk.co.uk.
Is EPS insulation environmentally friendly?
Yes, EPS insulation helps reduce energy consumption by providing effective thermal resistance, which reduces heating and cooling needs. It’s also recyclable and supports eco-friendly construction practices.
