- SuperHomer Susan Venner talks about using cork insulation both internally and externally during the eco refurbishment of her Victorian end of terrace house. In her experience cork insulation is highly suitable for insulating solid walls.
Susan chose to use cork insulation for a number of reasons.
* It is a natural material with low embodied energy
* It is suitable for use internally and externally
* Using it supports the cork industry which is struggling due to the change from corks to plastic stoppers
180mm of cork insulation was used externally. This was not rendered as the colour of the cork is close to the colour of the brickwork. Timber batons have been added to provide a climbing frame for plants. 120mm of cork insulation was used internally, covered with mesh then plaster skimmed.
Susan's home has undergone extensive eco renovation and also includes the use of Slimlite Double Glazing in the sash windows. It is one of the homes in the SuperHomes network of older homes that have been renovated by their owners to reduce carbon emissions by at least 60%. Most SuperHomes host public open days in Spring or September. For more, visit:

Very interesting video. I hadn't considered the idea of using expanded cork exposed to the elements as on this house. I will be interesting to see how it holds up over time. I agree that it is a very good colour match for the existing brickwork. Great idea!
Cork is fantastic material..
Cork is a fantastic material! Its main problem is that it is not as efficient an insulator as many of the man-made alternatives, which means that it may not be suitable when space is tight. If you have the space to use it, I would highly recommend cork.
How is this system getting on now?
hello
how is the external cork holding up after nearly 10 yrs, has the ivy penetrated it
If there is air and water infiltration behind the cork, it won't be very efficient will it? Did you 'glue' the cork to the wall with for example, hot bitumen to stop infiltration?
It is stuck with a specific adhesive
