A wall treatment is it purported that simple wall coverings or treatments of less than 1mm can reduce the heating load of an older solid wall type of home.  These claims are the subject of much debate.  The objective of this research was to use a systematic study of the currently available products using internationally accepted test methods to study the likelihood and quantity of any savings that can be directly attributed.

Following a detailed study of the coatings in the thermal laboratory in series of experiments, including traditional coatings such as normal paint, the samples were examined under a scanning electronic microscope and x ray analysis to understand the internal structure of the materials.

The provided a series of material characteristics that we re used to make changes to a fully validated, calibrated model of the Energy House test facility at the University of Salford  (Marshall et al., 2017),

The main findings of this work are:

  • Measured thermal resistance of thermal paint and general wall coverings are alike.
  • Thermal paint coatings & additives are thin (<1 mm) and do not show low-e surfaces.
  • Regular EPS liners give more effective thermal insulation levels at a lower cost.
  • Microscopy of insulating additives suggest the structure is not nano-porous.
  • The payback period is longer than a human life span for thermal paint coatings.
