This exterior insulation reduces the thermal bridging effect that studs have in a wall because each piece of framing can act as a thermal bridge through the cavity insulation. Insulation is one of the most important factors that contribute to a home s energy efficiency or inefficiency. 1 in field testing on identical 2x4 exterior wall types greenfiber r 13 stabilized spray applied insulation outperforms r 15 unfaced fiberglass batts by 4 nic raring points which equates to a 60 reduction in sound power.

Loose fill is blown into or sometimes damp sprayed into attic rafter spaces and wall cavities. The point of insulation is to combat the movement of air. Yet polystyrene is a fabulous insulator with r values that range from r 3 8 to r 4 4 per inch of thickness and so it s considered green because it helps save so much energy source. Polystyrene doesn t sound like a green material.

And since air can move in all sorts of directions insulation is needed in roofs ceilings walls and floors to prevent air from entering and leaving.

The weak point in the assembly such as flanking through windows and doors will diminish the value of the reduction in sound power.
