Since 1928, Hemsec has been one of the UK’s leading manufacturers of insulated panels - a trusted, values-driven partner known for delivering high-quality, UK manufactured solutions to the construction industry.
Hemsec manufactures high-performance insulated panels in both steel and timber-framed formats, designed to support energy-efficient commercial, leisure, and residential buildings.
Our Structural Insulated Panels (SIPs) are BBA-certified and ideal for fabric-first Modern Methods of Construction (MMC), enabling flexible, sustainable designs that can meet – and often exceed – Passivhaus standards.
Hemsec SIPs offer exceptional structural strength, allowing large roof spans without additional trusses and increasing internal space and natural light. Our wide range of panel sizes provides unrivalled design flexibility - from ultra-thin profiles that maximise usable floor area, to the UK’s thickest panels for industry-leading thermal performance.
Our steel-faced insulated panels deliver the same exceptional thermal efficiency and strength, while remaining incredibly lightweight. In high-performing technical environments, such as data centres, pharmaceutical clean rooms, freezer rooms, cold storage facilities, medical environments, or vertical farms, these panels could significantly reduce or eliminate the need for additional supporting steelwork.
High-performing. Fire resistant. Adaptable. All Hemsec panels undergo rigorous structural testing for fire and thermal performance. Our OSB/3 timber is PEFC-certified, demonstrating our commitment to responsible forestry and sustainable sourcing.
“I believe that Hemsec are best placed to service the needs of the construction industry heading towards new regulations in 2025 and the target of net zero.”
