Interior insulation retrofit of a brick wall using super insulation materials: design of a field testing in an industrial brick building

Johansson, Pär,1986Chalmers tekniska högskola,Chalmers University of Technology (author)

The societal demands on a more energy efficient building stock in Sweden creates challenges to find suitable retrofitting measures. One of the measures currently discussed is to use interior insulation. This measure leads to a reduced temperature in the wall, which increases to a risk for elevated moisture levels in the wall. When the thickness of the insulation layer is limited, super insulation materials (SIM) may be used. SIM can be divided into advanced porous materials, such as aerogel blankets (AB), and vacuum insulation panels (VIP). Often moisture from the outside is the major moisture source why a solution may be to apply a water repellent substance on the surface. A previous study showed that it is difficult to predict all the uncertainties in the field using the hygrothermal numerical simulations. This paper presents the design of a field investigation of a homogenous brick wall where AB and VIP are installed as interior insulation.
