i wonder whether in part it was also to do with the quality of paints, and also the wood itself. plus of course, the use of coal fires, not central heating. obviously with a coal fire, you need a fair amount of air movement, so some leakage does not really matter whereas with central heating and the hoary chestnut global warming  you need to reduce the air exchange, and also the wood is more likely to be kiln dried, and thus less stable. obviously time and money are important, but i think also the fact that you can't see it. ;D paul  |

I was talking more about the rebates on doors etc where a panel is going to be . I suppose any rebate your not able to get to once the joinery is glued up .

All I know is, from having demolished hundreds of doors , windows etc, that absolutely nothing which is out of sight is ever painted in trad work.
1st its a waste of paint. 2nd reason much more important is that it allows stuff to dry out if it gets wet.
Most obvious in window frames where a modern window with the sill painted underneath with primer, and set on solid mortar, can fill with water and become completely water-logged, if there is a gap in the paintwork or other fault above.
A trad window underneath will have no paint, an air gap of some sort, and minimal draught proofing with a bead of mastic or mortar. May get wet but has good chance of drying out and will last for hundreds of years.
cheers
