External / Internal wall insulation

[Awkward Knee]

Has anyone had external and internal wall insulation professionally fitted to a terraced Victorian property?

If so could you recommend a company?

Hi there, from what I've seen I haven't met anyone in ED who has had external wall insulation. This is due to the cost factor involved in external wall, plus it's only a realistic approach if you property is end of terrace, large flank wall. The front will not generally be done as it's going to add about 200-250mm, will look out of place and generally given the wall area to window area is not going to make a noticeable difference, generally speaking. Plus it's going to look odd next to your neighbours.

From experience, the rear of the property is mainly insulated. Points to bear in mind are that exit pipes, boiler flues and rainwater down pipes will need to be moved/extended, plus you need to consider how much of an overhang there is on the roof and will it carry on past the new wall surface? this can be resolved however.

Internal wall insulation is a different matter. The increased wall thickness will reduce space within the property, anything from 100-250mm depending. Some period features will be lost, dado rails and cornices but can be reinstated afterwards with a copy.

Speaking from experience, one of the best solutions is an insulating plaster. This can applied by a normal tradesman, depths of either 20/40mm will still have a significant impact, is cheaper, still allows walls to breathe etc and negates the use of membranes and problems with interstitial condensation.

I hope this has been of some help, choosing the right insulation is very important depending upon your aims and budget, plus it's great to hear someone is ahead of the curve!
