Hi All we have a small scullery-type extension on the back entrance to our house. It is single skinned brick and has not great roof insulation, although it does have an old double-glazed metal door. So it takes the worst of the winter weather off but remains on the cold side.
The other side of this, forming the main door to the house, is an old but solid half-glazed wooden door, fairly well fitted. I am not sure whether this was the original back door, before the extension was built, or whether it is a normal internal style. It seems somewhat in-between to me.
I am wondering about thermal improvements that could be made to this arrangement, without too much work.
Are there any style of half-glazed "internal" doors that are (a) double glazed and (b) have good insulation in the rest of the door?
I don't really want to fit an external grade door to this second entrance, that would mean you having to open two 'heavy' doors in order to get into the body of the house.
Thanks for any thoughts J^n
