The insulation has certainly been effective in the way heat is retained longer ... the Govt subsidy helped too of course . R3.8 wool blanket in ceiling and R1.4 compressed under floor.
I'm aware of the foam-filled wall drilling system but that seemed an expensive and messy undertaking ... and the house has thick old timbers inside and out (Totara, Matai, Kauri etc) plus 'modern' Gib.
Double glazing would be great for these large old casement windows but I've never really liked the magnetic system ... maybe if Lotto comes up we could get new d/g windows made to order .
Bung: Foil lined Gib was a bad idea and stopped being used in the 90's.
I was reading about it recently, a USA website. It's not foil lined gib, but they put some kind of metal foil in the walls. I can't remember why.

Makes a huge difference to the comfort of the house doesn't it?!
The "magnetic" double glazing isn't really magnetic, not always, it can be permanently fitted. Mine looks like a frame within a frame. It's not perfect, but it looks fine and changes the windows from wet with pools of water underneath them to having a light mist.
I think with those they might put on magnetic panels that can be removed in summer. The problem is the panels are quite heavy, and the magnets aren't that strong. Big big windows have the panels screwed in to them, but my smaller windows have them removable. All my windows swing outward so it doesn't really matter.
