Super insulation render for renovation and new constructions
This project aims at investigating and further developing solutions using a new type of aerogel plaster. The energy saving potential is very large, as 27% of Sweden's multi-family houses today have a plaster façade. Plaster are primarily used as water-repellent layer and protect the often non-insulated structure. Aerogel plaster can give a significant reduction in energy use, where the U-value can be reduced by 70% with a 5-6 cm thick plaster. If 10% of Sweden's plaster houses (brick and light-weight concrete) are equipped with aerogel plaster, 77 GWh can be saved annually. The project consists of laboratory study, hygrothermal modeling and field test. The aim is to give recommendations for using aerogel plaster in Sweden. The effect of temperature, humidity, alkalinity and mechanical stresses on the aerogel is assessed, as well as the heat and moisture properties of different types of aerogel renders adapted for buildings, are simulated and measured in the laboratory and in the field.
