Product Overview
EPS100 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 EPS100 grade, it achieves a compressive strength of 100kPa, making it suitable for use beneath non-structural or lightly loaded floor systems, as well as in general insulation build-ups. While not classed as a load-bearing structural material, EPS100 maintains shape and support when used under screeds, slabs, or flooring layers subject to standard domestic or light commercial loads.
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.
Features & Benefits
- High compressive strength: EPS100 rating provides 100kPa resistance under compression, suitable for non-structural flooring and general insulation applications.
- Lightweight composition: Easy to handle, cut, and fit with standard tools, reducing installation time.
- Multi-application suitability: Compatible with floors, walls, and roofs in both new-build and retrofit projects.
- Board size 2400mm x 1200mm x 100mm: Provides maximum thickness within the EPS100 range for deeper void filling and standard-grade insulation performance.
Applications
- Floor insulation: Suitable beneath screeds, ground-bearing slabs, or suspended floors where compressive stability is required.
- Wall lining and cavity fill: Provides modest thermal resistance in internal linings or cavity walls.
- Roof insulation: Used in flat or pitched roof systems under membranes or deck coverings.
- Perimeter insulation: Ensures continuity of insulation around slab edges or external walls.
Installation Guidance
- Surface preparation: Ensure substrate is level, clean, and dry before laying boards.
- Board fixing: Lay boards tightly with staggered joints to prevent thermal bridging.
- Adhesive or mechanical fixing: Use approved insulation adhesives or fixings suited to substrate and application.
- Cutting: Trim boards with a fine-toothed saw or hot wire cutter for accurate fitting.
- Protection: Avoid prolonged UV exposure and protect from solvents or hydrocarbons.
Compliance & Performance
- Material specification: Expanded polystyrene insulation conforming to BS EN 13163.
- Compressive strength: Minimum 100kPa at 10% compression.
- Thermal conductivity: Typical value 0.038 W/m·K.
- Important note: Always verify compatibility with adhesives and finishes to ensure material integrity.
