If you are unsure of your home's wall type, select 'I don't know the wall construction' option and we will decide what is most likely based on the answers you've already given us.
Solid walls: these are typically built from a solid layer of stone or brick, and do not have a cavity. They tend to be thick walls and are common in older properties built before 1930.
Cavity walls: these are made of an inner and an outer layer of brick with an air gap between them. They are typical in homes built in the 1960s and 1970s. If known, please indicate whether your cavity wall has been insulated.
Timber framed: a house where a timber frame is the structural support for the property. Early timber frame houses are easy to identify by their narrow walls of usually less than 200mm thickness. Modern timber frame houses are more challenging to identify as they usually have some form of cladding, making them appear similar in style to other construction types.
