From a functional point of view, external insulation can achieve higher levels of insulation with little risk of moisture problems either internally or within the wall structure, assuming it is correctly installed. It also maintains the thermal mass of the building by keeping the masonry within the insulation envelope.
Is there a benefit to insulating interior walls?

What is the cheapest way to insulate an old house?
Cheap Ways to Insulate a Building Consider the R-Value. R-value refers to thermal resistance. Spray Foam Insulation. Spray foam insulation seals leaks and gaps inside existing walls. Rigid Foam Insulation. Cellulose Insulation. Fiberglass Batts. Radiant Barrier. Recycled Material.

How effective is external wall insulation?
External wall insulation significantly reduces this heat loss, leading to a reduction in annual fuels bills by as much as 25%. External Wall Insulation systems also protect the building structure, prevent deterioration, and overcome thermal bridging and condensation problems.
