Use of Lightweight Thermal Insulation Materials Promoting Inclusivity in Construction Workforce

This paper examines the theoretical relationships between sustainable lightweight construction materials developed within the SNUG project “Circular Economy Based Materials Development to Foster The Transition to Sustainable and High-Energy Performance Buildings at Optimal Costs” and workforce accessibility in the building sector, with particular attention to ergonomic and gender inclusion dimensions. The study analyses four material innovations evaluating how their physical and installation characteristics may influence the demands placed on construction workers: aerated eco-concrete blocks, self-levelling mortars incorporating phase change materials, aerogel-based insulation and plasters, and bio-based hemp fibre panels. The methodology is literature-based and analytical, drawing on established ergonomics principles, material performance data, and workforce research to identify plausible pathways through which reduced material weight and technically sophisticated installation processes could lower physical barriers and broaden workforce participation. Results indicate that SNUG materials collectively shift installation emphasis from physical strength toward technical knowledge, precision, and equipment operation, though empirical validation remains absent. The paper concludes that the transition to sustainable construction presents an opportunity to intentionally integrate social and environmental goals, while cautioning against premature claims.
