100mm White Polystyrene EPS External Wall Insulation

100mm White Polystyrene boards deliver superior thermal performance through integrated graphite particles that reflect radiant heat. This rigid EPS closed-cell insulation traps air within each bead, creating an effective barrier against heat transfer. The graphite-enhanced structure provides a distinctive White appearance whilst boosting energy efficiency.

Graphite infusion throughout the cell structure of these 100mm boards creates reflective properties that slow radiant heat movement significantly. As warm air navigates the convoluted paths within the insulation, heat transfer is substantially reduced, delivering improved thermal conductivity of 0.031 W/mK—outperforming standard expanded polystyrene boards.

Benefits of Expanded Polystyrene (EPS) White Insulation

1. Enhanced Thermal Performance: Graphite particles boost the insulation's thermal properties, substantially lowering energy demands for heating and cooling applications.
2. Cost-Effective: Delivers excellent performance at competitive pricing compared to alternative insulation solutions, offering outstanding value for money.
3. Lightweight: Simple to transport and fit, reducing both labour expenses and installation duration.
4. High Moisture Resistance: 100mm EPS insulation resists moisture absorption effectively, preserving thermal performance throughout its lifespan.
5. Durability: Maintains insulating capability and structural stability over extended periods without degradation.
6. Environmentally Friendly: Frequently manufactured with recycled materials and fully recyclable, supporting green building practices.
7. Ease of Installation: Cuts readily to any required shape or dimension, offering flexibility across diverse project requirements.
8. Mold and Mildew Resistant: Natural resistance to fungal growth ensures healthier interior spaces.
9. Versatility: Performs excellently across walls, roofs, floors, and foundations in varied applications.
10. Improved Fire Resistance: Select White EPS products feature fire-retardant treatments for enhanced safety standards.
11. Low Thermal Conductivity: Minimises heat transfer efficiently, maximising building energy performance.
12. Minimal Thermal Bridging: Significantly reduces thermal bridging risks, preventing heat loss and unnecessary energy expenditure.
13. Acoustic Insulation: Contributes meaningful sound insulation benefits, creating quieter interior environments.

Characteristics

• Lightweight construction
• Cuts easily with sharp tools to any dimension
• Excellent mold growth resistance
• Maintains durability when installed correctly
• Budget-friendly option
• Eco-conscious Green Way product

Installation

The 100mm EPS boards attach to substrates (masonry or timber) using mortar, adhesive, mechanical fixings, or combined methods. The 100mm expanded polystyrene boards require an outer protective layer such as siding or mortar coating. Surface preparation involves rasping or sanding to create texture before applying fiber mesh, followed by base coat or mortar application.

Certifications

Manufactured to EN-13163 Standard specifications.
