50mm White Polystyrene EPS External Wall Insulation

50mm White Polystyrene boards deliver superior thermal performance through integrated graphite technology that enhances heat reflection. This rigid expanded polystyrene (EPS) insulation features closed-cell construction that traps air within each bead, effectively minimising heat transfer through your external walls.

Graphite-enhanced EPS boards incorporate reflective particles throughout their cell structure, creating a distinctive White appearance whilst improving thermal efficiency. As radiant heat passes through the 50mm boards, graphite particles reflect it multiple times, substantially reducing heat loss and boosting energy performance to 0.031 W/mK—significantly better than standard EPS alternatives.

Warm air follows a winding path towards cooler zones within the board structure, slowing thermal movement and maintaining interior warmth. This advanced composition delivers an R-Value of 1.15m2K/W, making it an excellent choice for external wall applications.

Installation

The 50mm EPS boards attach to substrates (masonry or timber) using mortar, adhesive, mechanical fixings, or combined methods. The 50mm expanded polystyrene boards require an outer protective layer such as cladding or mortar finish. Before applying fiber mesh and base coat, rasp or sand the board surface to create proper adhesion for the mortar layer.

Certifications

Manufactured to EN-13163 Standard specifications.
