EPS70 Polystyrene Insulation Board with a 2400mm length, 1200mm width, and 100mm thickness. 

Manufactured from expanded polystyrene beads fused into a rigid, lightweight sheet, this board provides reliable compressive strength and dimensional stability across a broad range of construction applications.

Rated to EPS70 grade, it achieves a compressive strength of 70kPa, making it suitable for use beneath non-load-bearing floors, walls, and roofs where lighter or less demanding applications are required. While not classed as a structural material, EPS70 retains its shape and support under typical domestic floor loads and general insulation build-ups.

Designed for use in floors, walls, and roofs, it offers easy handling, precise cutting, and quick installation. The overall dimensions of 2400mm x 1200mm x 100mm offer maximum material depth for improved basic thermal resistance.

 

Specifications

  • Board Size: 2400 mm (length) × 1200 mm (width)
  • Thickness: 100 mm
  • Material: Closed‑cell Expanded Polystyrene (EPS), grade EPS70
  • Thermal Conductivity: 0.038 W/m·K
  • Compressive Strength: Rated for 70 kPa at 10% compression (standard for EPS70)
  • Useable Temperature: Range Up to ~80 °C — safe for underfloor heating systems.

 

Performance

  • Thermal insulation: With λ = 0.038 W/m·K, very effective for lowering U‑values when used under floor screed or chipboard / finishing layers.
  • Structural suitability (for domestic loads): Compressive strength adequate for typical domestic floor loads when covered by screed / chipboard; not designed for heavy industrial loads.
  • Durability / Long-term stability: EPS is dimensionally stable over time, non‑hygroscopic (resists moisture), rot‑proof, flood-resistant, and resistant to freeze/thaw cycles.
  • Compatibility with underfloor heating: Suitable up to 80 °C — compatible with warm‑water underfloor heating systems.

 

Features and Benefits

  • Lightweight & easy to handle — simplifies transport and installation on site.
  • Cost‑effective insulation — lower cost compared to rigid PIR when moderate thermal performance is acceptable; economical for domestic floors.
  • Good compressive strength for domestic floors — EPS70 rating sufficient under screed or chipboard for typical live loads.
  • Stable thermal performance over building life — EPS does not settle or significantly degrade, retains insulating properties for decades.
  • Moisture‑resistant, rot‑proof, non‑hygroscopic — suitable even for ground-floor slabs or where moisture ingress is possible.
  • Environmentally acceptable (to an extent) — 100% recyclable EPS, widely accepted in building projects.
  • Flexible application range — suitable for ground floor slab builds, suspended floors, under screed, under chipboard — good versatility

 

Applications

  • Thermal Insulation: Jablite Jabfloor 100 Polystyrene Insulation Board is primarily used for thermal insulation. It helps in maintaining the temperature of the building, reducing the need for heating or cooling systems, and thus saving energy.
  • Floor Insulation: It is specifically designed for floor insulation. It can be used in both new build and refurbishment projects.
  • Wall Insulation: This product can also be used for wall insulation. It helps in reducing heat loss through walls, thus maintaining a comfortable indoor environment.
  • Roof Insulation: Jablite Jabfloor 100 can be used for roof insulation. It helps in preventing heat loss through the roof, thus reducing energy consumption.
  • Basement Insulation: It can be used for insulating basements. It helps in preventing dampness and maintaining a comfortable temperature in the basement.
  • Sound Insulation: This product also provides sound insulation. It helps in reducing noise transmission through walls and floors, thus creating a quieter indoor environment.
  • Underfloor Heating Systems: Jablite Jabfloor 100 is suitable for use with underfloor heating systems. It helps in evenly distributing the heat and reducing heat loss.

Installation

The Jablite Jabfloor 100 Polystyrene Insulation Board can be installed above a concrete slab or a pre-cast concrete floor in ground-floor constructions. It is recommended to finish the installation with a layer of chipboard to meet the relevant U-value requirements.

Certifications

The Jablite Jabfloor 100 Polystyrene Insulation Board meets all relevant industry standards and certifications, ensuring its quality and performance. It is certified for use in both domestic and commercial applications.
