Insulation

A quick walk at lunchtime, passed these high rise flats being renovated with new external insulation.  I think that the original brickwork can be seen on the highest floors so this isn't replacement insulation as a result of the Grenfell Tower tragedy.

It's only now I look at the image that I've noticed that all of the balconies have had their balustrades removed.  As far as I am aware the residents haven't been moved out while the work is done.  At least some of them will be benefiting from the improved heat retention.
