150mm Grey Polystyrene EPS External Wall Insulation

150mm Grey Polystyrene (Graphite) represents a premium expanded polystyrene (EPS) board incorporating integrated graphite particles that deliver a distinctive grey appearance. The graphite content within the insulation beads reflects radiant heat, boosting thermal performance by approximately 20% when compared to standard 150mm white EPS insulation of equivalent thickness. This 150mm rigid EPS closed-cell product encapsulates air within each bead, and because air conducts heat poorly, it substantially reduces heat transmission rates.

Graphite particles distributed throughout the cell matrix of 150mm Grey Polystyrene (Graphite) boards create reflective surfaces and impart a striking dark grey finish. When radiant heat travels across the 150mm graphite insulation, it bounces repeatedly, dramatically decelerating heat flow and maximising energy performance.

Within 150mm Grey Polystyrene (Graphite) boards, warm air follows an indirect route towards cooler regions, decelerating heat transfer and maintaining interior warmth. This delivers superior thermal conductivity of 0.031 W/mK, outperforming conventional 150mm expanded polystyrene boards.

Benefits of Expanded Polystyrene (EPS) Grey Insulation

1. Enhanced Thermal Performance: Graphite incorporation within grey EPS elevates insulation capabilities, substantially lowering heating and cooling energy demands.
2. Cost-Effective: Delivers outstanding performance at competitive pricing relative to alternative insulation solutions, offering excellent value.
3. Lightweight: Straightforward to transport and fit, potentially lowering installation labour and timeframes.
4. High Moisture Resistance: 150mm EPS insulation resists moisture penetration effectively, preserving thermal properties throughout its lifespan.
5. Durability: Robust material that preserves insulating effectiveness and physical strength across decades of service.
6. Environmentally Friendly: Frequently manufactured from recycled materials and fully recyclable, supporting green building practices.
7. Ease of Installation: Cuts readily to match any dimension or configuration, providing flexibility across diverse projects.
8. Mold and Mildew Resistant: Built-in resistance prevents fungal colonisation, fostering healthier interior conditions.
9. Versatility: Applicable across numerous settings including walls, roofs, floors, and foundations.
10. Improved Fire Resistance: Selected grey EPS variants incorporate fire-retardant treatments for enhanced protection.
11. Low Thermal Conductivity: Minimises heat movement, strengthening building energy efficiency.
12. Minimal Thermal Bridging: Mitigates thermal bridging risks, preventing heat escape and unnecessary energy expenditure.
13. Acoustic Insulation: Contributes modest sound insulation qualities, creating quieter spaces.

Characteristics

• Lightweight
• Easily cut with a sharp knife to any size and shape
• High resistance to mold growth
• Highly durable when used according to specifications
• Cost-efficient
• Environmentally friendly Green Way product

Installation

The 150mm EPS boards are initially secured to the substrate (masonry or timber) via mortar/adhesive, mechanical anchors, or a hybrid approach. The 150mm expanded polystyrene boards must subsequently be protected with an external finish, including cladding or mortar coating. The board's outer face requires rasping or sanding to establish a textured surface prior to application of fiber mesh, followed by base coat or mortar application.

Certifications

Produced in accordance with EN-13163 Standard.
