ahah ! bit of excitement in the over sixties community where i reside. wall cavity filling ... indeed!
many holes being drilled, noisily.
many workmen in overalls wielding the instruments required for wall cavity filling.
i guess i will be privileged to be even warmer than i already am. scotland can be cold but mostly we have this blanket of cloud cover to keep us moderately warmer than those who exist under clearer skies than ours.
still, i am reliably informed that i will save on heating costs and considering they are executing the procedure on the outer walls of my apartment for free. solely due i believe, to my somewhat impecunious circumstances, well, who am i to say them nay!
