Insulation in Victorian terrace house

    I currently live in a terraced, redbrick Victorian house. The house has no insulation and I am looking to get a company in to do all the insulation. Before I start making calls I am looking for recommendations on how best I should insulate the house.

    Attic - I would prefer to insulate the roof as opposed to the attic floor, which will be used for storage.

    Walls Front- I think the walls are rubble stone, fronted in red brick to the front of the house. I have original lathe and plaster ceilings wall original coving, which I want to retain. I know this will make it difficult to dry line.

    Walls Rear - The lower floor is partially new, with a cavity, but rest and upper floors are original, Have not drilled so do not know if there is a cavity. I have the same issue with original plaster in upper bedroom, but could I insulate outside of house?

    Floor - on the ground floor I have crawl space beneath the floor boards and ventilation into this. This is divided into three seperate areas and is about 3 feet in height. There is a trap door cut and renailed into one of these crawl spaces.

    Windows - These were double glazed about 15-20 years ago with white uPVC but not really in keeping with the style of the house. I would like to upgrade to new sash windows, but the house is on a very busy main road so noise is a major issue.


    I know this is a big job to do all this but really want to get it done as well as possible. I have already renovated the house so would like to do the work with as little impact on the interior as possible.

    All advice and recommendations greatly appreciated. I also need recommendations (please PM) for companies/contractors to do the work. I am based in Dublin (North City)

    I think the way to insulate your external walls would be to fix insulated boards and get new cornice ran up and replaced to match the existing.
    You would only lose 100mm or so of internal space depending on your required depth of boards. I have done this a few times and its not too big a job.
    Sometimes the existing render has lost its bond and may have to be taken off the walls, a lime based render can then be applied to straighten walls and allow them to breath before fixing insulated boards.

    The ventilation in your tassle walls is required for your floor joists, a rigid insulation could be fixed between the joists to the underside of your flooring, this would improve your heat retention in this area, you could also fix plywood down beneath your finished floor which would also improve the heat loss/ draughts.

    The correct thing is to do the whole job together including the windows as you will not get the benefit of the remedial works if you don't do all aspects.
