In-situ temperature monitoring of an internal insulated wall in a historic building

Internal insulation using calcium silicate board and phenolic foam significantly alters temperature dynamics in historic masonry, as demonstrated by in-situ monitoring of a wall in Levoča’s Spišský Hrad. The study found that insulated walls exhibit distinct thermal behavior compared to uninsulated references, with measurable differences in surface temperatures, sub-insulation layers, and deeper masonry (100 mm depth). These findings highlight the impact of insulation materials on perimeter structures while also assessing their influence on indoor environmental quality. By comparing temperature profiles under different insulation conditions—calcium silicate board and phenolic foam—the research provides critical insights for preserving thermal performance in heritage buildings without compromising structural integrity.
