The upper timber walls are injected with Warmcel (recycled newspaper) insulation which is highly vapour open (‘breathable’) thereby safeguarding the building should moisture make it past the air and vapour layer. Core holes are drilled in the board, the insulation injected, and then the plug reinserted and taped over. Note the test hole where the insulation thickness of 340mm and the associated density has been noted – critical to ensure the insulation doesn’t slump. Pumping the insulation completely fills awkward spaces saving labour costs, and being newspaper, sequesters carbon – a great solution, but unfortunately rarely used.
