Walls

In non-extreme climates, due to the seasonal variation, all of these conditions will be encountered during the year.This means that in general, wall insulation will always bring positive benefits. There may be some situations, however, where benefits may small in comparison with the cost, or present technical difficulty and/or unacceptable visual impact.This is sometimes the case in historic buildings. Or there may be buildings where due to high internal gains, the lack of need of close temperature control or the nature of the activity, heating and cooling loads are already modest.
