I think my error was I was focused on the older housing as that is where my professional interest lies as I manage rental properties, most of which are victorian or early 1900's vintage. My main interest in. HPs is because I can see I am goi g to have to deal with the upgrades in the future and am trying to work out how to approach it.

That is an interesting problem, and one that may require a creative engineering solution. Link to comment Share on other sites More sharing options...

The thing is, I don't think it requires any creative or novel engineering. The major hurdles are finance and regulations (sound, visual etc) Link to comment Share on other sites More sharing options...

That is where the engineering creativity comes in. Creativity isn't my problem. It's the restrictions. They, in turn add cost. I have a nice cladding system i am trialing on an out of the way building. No way I would be allowed to fit it to my main buildings because of planning restrictions combined with it's industrial look Personally,, I think there is a pint when how warm and cheap to run a building is for the occupants trumps how it looks for the passers by. But my view is very much in the minority, so solid walls and single glazed windows it is. Link to comment Share on other sites More sharing options...

My LPA wouldn't let me fit double glazed metal framed windows in a refurbished property when single glazed metal framed windows had to be replaced. So we were forced to put in new single glazed metal frame windows. This was in a property originally built in 1860. Would it even have had metal windows when first built - I doubt it. Nuts.
