Explore distinct product types and their applications below to ascertain the most apt EPS product for your needs.

What is Expanded Polystyrene (EPS)?

Expanded Polystyrene (EPS) is a rigid, closed-cell insulation material made from polystyrene beads that expand under heat to form lightweight boards. EPS is widely used in the construction industry for its impressive thermal performance, moisture resistance, and affordability. It’s commonly applied in floors, roofs, and wall insulation, helping buildings stay energy-efficient all year round.

Standard EPS Sheets

Standard EPS 70, available in 2400mm x 1200mm size across all applicable thicknesses, and the Enhanced EPS, available in 1200mm x 600mm dimensions, serve as the fundamental insulation components suitable for a myriad of applications. Their practical uses span from wall insulation in cavity walls, and floor insulation to even under-soffit application, ensuring a thermally efficient envelope in diverse building scenarios.

Thermal Laminates

Differing from basic EPS, thermal laminates like the ones offered by Knauf and Thermboard in 1.2m x 2.4m sizes cater to drylining applications. The Knauf EPS Thermal Laminate and Thermboard EPS Thermal Laminate are designed to provide an enhanced thermal barrier when applied to internal wall structures. Adaptable and easy to install, these products ensure internal environments maintain a stable and desirable temperature, significantly impacting energy efficiency and comfort.

Gyproc ThermaLine

British Gypsum’s Gyproc ThermaLine, available in 1.2m x 2.4m size, is another credible option in thermal laminates, establishing itself as a choice product for improved thermal performance, particularly in wall partitioning and lining systems. 

Warmline EPS Insulated Plasterboard

Warmline EPS insulated plasterboards, available in 1.2m x 2.4m size and all related thicknesses, deliver a two-in-one solution of insulation and drylining, reducing the need for multiple product applications and thereby optimising the construction timeline.

High-Density EPS

The High Density EPS 200e series showcases EPS sheets in various thicknesses, ranging from 20mm to 90mm, packaged in bundles tailored to your project scale. Notably durable and robust, these high-density variants are particularly suited for applications requiring enhanced compressive strength, such as floor insulation in high-traffic areas or underneath heavy load-bearing structures. 

Selecting Your EPS Product

• For General Purpose Insulation: Standard EPS Sheets: Choose EPS 70 or Enhanced EPS for a wide range of standard insulation applications.
• For Internal Wall Applications: Thermal Laminates: Opt for Knauf, Thermboard, or Gyproc ThermaLine Basic Insulation for thermal laminates that can be applied directly to internal walls for improved thermal performance.
• Integrated Solutions: Select Warmline EPS Insulated Plasterboard when seeking an integrated insulation and drylining solution.
• For High Traffic/Load Areas: Leverage High Density EPS 200e in required thicknesses to ensure optimal compressive strength in areas demanding heightened durability and stability.

Benefits of EPS Insulation

• Excellent Thermal Insulation: EPS delivers consistent and reliable thermal performance, reducing heat loss and improving overall energy efficiency.
• Lightweight Yet Strong: Despite being lightweight, EPS boards offer excellent compressive strength, making them easy to handle without compromising durability.
• Water and Moisture Resistance: EPS resists moisture absorption, helping maintain its insulating properties even in damp conditions.
• Cost-Effective Solution: EPS is one of the most affordable insulation options, providing high performance at a competitive price.
• Eco-Friendly: Fully recyclable and manufactured using low environmental impact methods, EPS supports sustainable building practices.

Applications of Expanded Polystyrene (EPS)

• Floor Insulation: Used under concrete slabs and suspended floors to prevent heat loss and improve energy ratings.
• Roof Insulation: Ideal for both flat and pitched roofs, EPS helps regulate indoor temperatures and reduce heating bills.
• Wall Insulation: Commonly installed in cavity walls or externally as part of an insulated render system.
• External Wall Systems (EWI): EPS boards are frequently used in external wall insulation systems to improve a building’s thermal envelope.
• Underfloor Heating: Provides a stable and thermally efficient base for underfloor heating installations.
