I am getting close to having windows installed (its been a long journey to here), my brickies have installed dpc and then vertical insulation reveal strips to the inside of the external skin of block and returned the inside block to meet this and close the cavity. At the head we have nothing other than internal & external head along with a filler head to partially close the cavity. My thought is to use some more pir reveal strips to close the remainder of the cavity and some low expansion foam if necessary. Is my thinking right?
Lets assume it is, I am full filling the cavity with blown beads what should I do with the area under the sloped DPC above heads (see image)? Do I just leave this and assume/instruct/trust the insulation installers to blow beads into this section?
Thanks again in advance.
