EPS Insulation Board – Polystyrene – Residential & Commercial

Product Overview

This industrial grade polystyrene insulation board offers a length of 2400mm, width of 1200mm, and thickness of 100mm. Crafted from expanded polystyrene beads fused into a rigid, lightweight sheet, this board delivers reliable compressive strength and dimensional stability for various construction applications. Rated to EPS100 grade, it provides a compressive strength of 100kPa, making it ideal for use beneath non-structural or lightly loaded floor systems, as well as in general insulation build-ups.

Features & Benefits

• High compressive strength: EPS100 rating ensures 100kPa resistance, suitable for non-structural flooring and 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: Offers modest thermal resistance in internal linings or cavity walls.
• Roof insulation: Applicable 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.

• Material: Expanded polystyrene
• Compressive strength: 100kPa
• Conforms to: BS EN 131
