Your method of cunstruction is certainly cheaper but I'd like to see
comparative thermal performance figures.
Eh? Extra long bricks (matching the facing bricks) cheaper than wall
ties (which are basically large stainless-steel paperclips)? I think not!
The ties are cheaper. Galvanised steel (not stainless) isn't expensive.
I thought galvanised ties were no longer allowed, and stainless was
required in new builds.
The ones used by magpies to build a nest in one of our trees were ss. I was
surprised because I'd only ever seen galvanised.
Magpies like shiny things of course. Maybe they were being choosey ?
