I am building a new house. How does the cost of Supernova Silver Bead compare with that of fitting traditional polystyrene insulation boards in the cavity?
Once you take account of the cost of labour and the wastage associated with traditional board insulation Supernova Silver Bead compares very favourably. On a new build the insulation is pumped into the cavity wall through the interior wall before they are plastered. The drill holes are filled in and then cover during plastering.
