High Density Under Slab Insulation Expanded Polystyrene Board Partition Wall Expanded Polystyrene Board

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Thermal Insulation: High-density XPS (extruded polystyrene) board designed to provide exceptional thermal resistance for under-slab foundations and partition walls, minimizing heat transfer.
  • Structural Partitioning: Engineered for durable, lightweight wall construction in commercial and residential settings, ensuring acoustic and thermal separation.

Key features

  • 1. Material Technology

    • With high-density expanded polystyrene (XPS) material and B1/B2 flammability ratings, achieve superior thermal insulation and fire resistance for safe, energy-efficient construction.

  • 2. Performance Parameters

    • With a density ~30% higher than standard EPS boards*, deliver enhanced thermal resistance (R-value) to reduce energy loss in commercial and residential spaces.

  • 3. Scenario Solutions

    • Designed for under-slab and partition wall applications, effectively insulate high-traffic commercial spaces like supermarkets while maintaining structural integrity in demanding environments.

  • 4. Interactive Design

    • With uniform thickness and smooth surfaces, easily cut or shape the boards to fit precise insulation needs, streamlining installation in diverse construction projects.

  • 5. Certification Standards

    • Backed by CE certification, ensure compliance with EU safety and quality standards for seamless integration into international building codes and regulations.

Product details

High Density Under Slab Insulation Expanded Polystyrene Board Partition Wall Expanded Polystyrene Board

The High-Density XPS Insulation Board is a premium thermoplastic material engineered for superior thermal insulation and structural durability. Designed for commercial and residential applications, it offers customizable flammability ratings (B1/B2), CE certification, and seamless integration into wall partitions or under-slab systems.

Technical specifications

FeatureSpecificationBenefit
MaterialExtruded Polystyrene (XPS)Moisture-resistant, long-lasting insulation
CertificationCE-compliantEnsures safety and regulatory compliance
FlammabilityB1 (self-extinguishing) / B2 (slow-burning)Flexible fire safety options for diverse environments
Density32–40 kg/m³ (high-density)Enhanced compressive strength and thermal performance
Thickness25–100 mm (customizable)Adaptable to insulation and load requirements

Customization guide

Adjust thickness (25–100 mm) and flammability rating (B1/B2) to meet specific needs:

  • Thermal Efficiency: Thicker boards (e.g., 50+ mm) for extreme temperature zones.
  • Fire Safety: Opt for B1 rating in high-risk commercial spaces like supermarkets.

Get inspired

Ideal for supermarket wall partitions (noise reduction + energy efficiency) or under-slab insulation (moisture barrier + thermal stability). With its smooth, uniform surface, it can be easily cut to fit custom designs.

Supplier's note

  1. Three Breakthroughs:

    • Pro Model’s Moisture Shield: Reduces water absorption by 50% vs. standard XPS, ideal for under-slab use.
    • Advanced B1 Rating: Meets stringent fire codes for commercial buildings (e.g., supermarkets).
    • R-7 Thermal Performance: 40% higher than baseline, ensuring energy savings in extreme climates.

  2. Optimal Version Selection:

    • Base Model: Suitable for residential walls or low-risk zones requiring basic insulation.
    • Advanced Model: Best for supermarkets or offices needing B1 compliance and moderate load-bearing.
    • Pro Model: Recommended for industrial or coastal areas where moisture and fire resistance are critical.

With B1 flammability, you can meet commercial safety standards while maintaining thermal efficiency. Pair the Pro’s Moisture Shield with its R-7 rating to create a durable, long-lasting insulation system for harsh environments.
