‘Blown Loft insulation is the quickest way to meet the thermal regulations for both new build and existing loft spaces. 250mm blown loft insulation with an isolated 12.5mm plasterboad ceiling achieve more than 50dB sound reduction in a tiled roof construction.
Consistent density and flow rate; No foreign bodies; All bales to be within agreed weight tolerance; There shall be no deleterious effect on PVC or similarly covered electrical wiring.
Thermal conductivity (K value)= 0.043W/mK.’
