A method of constructing thermally insulated cavity wall in a quick manner with relatively unskilled labor comprises laying bricks, blocks or the like in successive courses without mortar or adhesive therebetween and injecting a foamable material into the cavity progressively as the wall is constructed. Joint spaces may be provided between adjacent blocks in each course so that the foamable material may bond to for example plaster board applied to the inner wall portion.
