Stormdry EP-Board - 1.2 × 0.6 m - Energy Performance Board

Stormdry EP-Board is a high-performance internal wall insulation board designed to reduce heat loss in solid wall properties without major disruption. Just 13 mm thick, each panel is constructed with an aerogel blanket bonded to magnesium oxide board to form a durable, breathable and moisture-resistant surface. The board dramatically improves thermal performance while maintaining slim internal profiles, making it ideal for retrofit upgrades where space is limited. Boards are installed using Stormdry EP-Board Adhesive, a fast-curing, straw-applied foam adhesive formulated specifically for use with EP-Board. The adhesive offers strong initial tack with minimal expansion, enabling quick, level installation directly onto masonry or plaster. Its B2 fire rating and water resistance ensure safe, long-lasting performance. Each 750 ml can covers up to 15 m2 and bonds securely with minimal surface preparation when applied correctly. Together, EP-Board and adhesive create a low-profile, energy-saving internal insulation system that improves occupant comfort while supporting compliance with modern thermal standards. Stormdry EP-Board is especially suited to homes seeking breathable, space-efficient thermal upgrades.
