Insulating a 19th century category C Listed Building

In partnership with Robert Gordons University, the challenge was to insulate a building without drilling any holes and thus leaving any wall finishes intact. The “harm-free” concept was the driver of this method as not a single hole was drilled into the building fabric as is generally the case. Understanding each building structure was the initial investigation as not all historic or traditionally built buildings are the same.
The Kishorn team managed in Bogendollo house to: identify access to the wall cavity that will allow the operation to take place, created ways to reach and insulate each individual bay of the wall, identify the wall’s weaknesses and dealt with them:

  • by controlling the foam expansion and pressure during its application,
  • by transforming the existing equipment and adapting it to the project
  • by releasing the appropriate quantity of liquid foam

The most important thing is that the team managed to keep the building as it was before the insulation project (visually) and improve its U-value by 50%

In partnership with the RGU and Icynene UK we are delighted to have won an Innovation in Housing Commendation for our work in treating traditional and hard to treat properties. This is the first time such insulation has been used in an historic building in Scotland. The water blown foam was created specifically for injecting into delicate structures. The foam expands slowly putting little pressure on the fragile inner wall and, as it is 100% water blown, it contains no harmful blowing agents. Additionally, through its open cell structure, the foam will allow the wall to breathe which will assist in controlling moisture movement.
