Cavity question

Victoria White (Opinion, Jan 17) claims she had foam pumped into her cavity block walls.

Cavity block walls (1 wall) are not the same as cavity walls (consisting of two individual walls with a gap between).

Could she explain how every individual cavity block was filled and at what cost?

A good BER rating is great, but houses may have both mould risk and air quality problems if totally sealed, and if ventilated the BER literally goes out the window.
