Houses that are listed or in conservation areas would not be allowed to have external insulation.

External insulation of the vessel is typically provided to minimize heat loss.

There was also an awareness of the need for relatively high levels of external insulation.

Modern concrete wall systems use both external insulation and thermal mass to create an energy-efficient building.

Thicknesses of internal or external insulation typically range between 50 and 100 mm.

With external insulation, there is more room available for workloads, for a given size of pressure vessel.

External insulation is not difficult and can enhance the appearance of a three bed semi, as usually the lime render has failed anyway.

Solid wall insulation: A building with solid walls can benefit from internal or external insulation.

Many lofts remain uninsulated, many cavity walls unfilled, modern external insulation can be an effective remedial repair as well as energy saving.

Council-owned no-fines houses benefitted from the installation of clearly visible external insulation panelling and improved ventilation to address perceived disadvantages with the no-fines construction.

External insulation keeps the wall structure itself above dew-point temperature, thus avoiding problems of condensation in the depth of the wall that can occur with internal insulation.

Both external and middle insulation are typically done during the construction of the house, although external insulation can be done in conjunction with a drainage project aimed at keeping water away from the foundation.

Continuous external insulation, high quality double glazed windows, high thermal inertia, mass walls, external shading to South, East and West windows, central solar thermal system, optional central heating system, green roofs, among many other sustainability oriented characteristics.

Putting the insulation on the outside yields the smallest pressure vessel for a given inside working diameter, but the energy required to heat up the vessel itself each cycle soon makes this a very unattractive way of economizing, unless steam injection is used for heating, in which event external insulation must be used.
