Internal heat preservation of the advantages: low cost, simple construction.
The shortcomings of internal insulation: thermal insulation effect is poor (because not all covered insulation layer), will appear condensation water (because the wall is cold, heat insulation layer is hot, inside and outside the formation of condensate), the impact of decoration (insulation layer in the interior decoration will damage the insulation layer), the impact of the area (construction area calculation rules).
The advantages of external insulation: insulation effect is good, does not occupy indoor space.
Disadvantages of external insulation: high cost, difficult construction (especially the top), construction technology requirement is high, and the wall decoration influential (exterior wall tiles higher technical requirements).
