The best solution
 Cavity wall with 60mm board already
fitted

in cavity (yellow) and topped up with
'Foamfill' (white) |
Insulation board is usually installed to a thickness of 60mm in a 105mm cavity, assuming the board is correctly installed the current required u-value of .027 w/m2/K is achieved.
To improve the thermal effiency of the wall the board can be topped up with  As the foam is injected under 130 lbs pressure, it will fill any voids left between the boards or any areas where the board is poorly fitted.
Why
FOAMFILL insulation is self supporting and will not settle or sag within the cavity to create voids. FOAMFILL will not absorb water and has excellent fire resistance. Unlike other insulation products, FoamFill has no effect on electrical cables or wall ties and is not effected by frost. It is rot and decay proof and requires no maintenance.

BEST U-VALUES
Whilst the installation of any cavity wall insulation will reduce heat loss and improve the thermal efficiency of the walls, none can compare with FOAMFILL A U-Value of .24 is easily achieved in a normal 100mm cavity compared with .34 using white polystyrene beads. A whopping 40% more efficient.
