Abstract In the context of increasing energy costs and the need for global reduction of CO2 emissions, the development of superinsulation materials for the construction sector allows the design of low-energy buildings. Since still being in an experimental or at early-commercial stage, R&D of these materials focused on its final application is required, to accelerate access to the market for renovation of the building stock where space is a critical metric. In this paper, the experimental assessment of the thermal performance of a novel ambient pressure dried silica aerogel based composite is presented. In order to provide assessments at both, material and system levels, stress-strain tests, hot plate measurements, as well as full scale tests under realistic boundary conditions were conducted. The overall results are that this material provides good insulation properties (thermal conductivity in the range of 0.015–0.018 W/mK), along with sufficient mechanical properties, and allows for the creation of superinsulating assemblies even at small wall thickness.
