Sorry for the confusion.
I was trying to imply i was open to either options. It would appear i would not get a grant because none of use obtain any state benefits.
It would seem injection from outside is easier, however i only have limited walkway access to rear, no vehicle access...
Good evening.
Basics- require insulation for single wall construction with stud wall in a bathroom. Do i work from the inside (boards) or from the outside (inject) ?.
If your not too bored already the details follow .
May i first start by saying how staggeringly ignorant i appear...
