In fact, their properties may vary with the moisture content, temperature, ageing degradation, etc. Therefore, in this work, the thermomechanical behaviour of different materials was compared when subjected to accelerated ageing. Insulation materials that use recycled rubber in their composition were studied, along with others for comparison: heat-pressed rubber, rubber_cork composites, aerogel_rubber composite (developed by the authors), silica aerogel, and extruded polystyrene. The ageing cycles comprised dry-heat, humid-heat, and cold conditions as the stages, during cycles of 3 and 6 weeks. The materials\u2019 properties after ageing were compared with the initial values. Aerogel-based materials showed superinsulation behaviour and good flexibility due to their very high porosity and reinforcement with fibres. Extruded polystyrene also had a low thermal conductivity but exhibited permanent deformation under compression. In general, the ageing conditions led to a very slight increase in the thermal conductivity, which vanished after drying of the samples in an oven, and to a decrease in Young\u2019s moduli.<\/jats:p>","DOI":"10.3390\/gels9030241","type":"journal-article","created":{"date-parts":[[2023,3,20]],"date-time":"2023-03-20T03:09:37Z","timestamp":1679281777000},"page":"241","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Thermomechanical Performance Assessment of Sustainable Buildings\u2019 Insulating Materials under Accelerated Ageing Conditions"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0400-4645","authenticated-orcid":false,"given":"Ana Dora Rodrigues","family":"Pontinha","sequence":"first","affiliation":[{"name":"University of Coimbra, CIEPQPF, Department of Chemical Engineering, 3004-531 Coimbra, Portugal"}]},{"given":"Johanna","family":"M\u00e4ntyneva","sequence":"additional","affiliation":[{"name":"H\u00e4me University of Applied Sciences, HAMK Tech Research Unit, 13100 H\u00e4meenlinna, Finland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0134-6762","authenticated-orcid":false,"given":"Paulo","family":"Santos","sequence":"additional","affiliation":[{"name":"University of Coimbra, ISISE, ARISE, Department of Civil Engineering, 3004-531 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3336-2449","authenticated-orcid":false,"given":"Lu\u00edsa","family":"Dur\u00e3es","sequence":"additional","affiliation":[{"name":"University of Coimbra, CIEPQPF, Department of Chemical Engineering, 3004-531 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"24","DOI":"10.1016\/j.conbuildmat.2013.10.038","article-title":"An Environmentally Friendly Thermal Insulation Material from Sunflower Stalk, Textile Waste and Stubble Fibres","volume":"51","author":"Binici","year":"2014","journal-title":"Constr.
