Insulate the house is a necessity for comfort and energy savings Effective and easy to implement: isolate the habitat from the outside.

In new buildings the insulation is placed at the building with more and more obvious, with a genuine concern for complete continuity of insulation, thermal bridge breakers for an optimal thermal and acoustic performance. insulation directly included in the thick walls or walls with panels as straw , or through the use of performance materials such as aerated concrete , or exterior insulation are among the most common techniques. By cons, a vast majority of habitats prior to the 1990s, reviewing the insulation of the house appears as a necessity especially in view of rising energy costs and, as such, a thermal diagnosis is an effective aid . Two solutions are then: interior insulation, exterior insulation. Common in Scandinavia and Germany in particular, the principle of external insulation is often seen as the best solution to completely isolate a house.

Home insulation from the outside, for what buildings?

Insulation is often considered in terms heat, but it also concerns the phonic aspect in many processes. Fighting against noise , fighting against the excesses of warmth against the cool habitat are three reasons which may lead to isolation from the outside. This is a very interesting method under construction. For existing housing, this process alters the exterior appearance. Also, it is essential to consult the planning rules of the common, and subdivision regulation if one exists, to know what is allowed or not at this level: consistency requirements imposed by the documents Planning, Land Use Plan (POS) and Local Development Plan (PLU) may prohibit the implementation or require certain rules.

The external insulation is excluded in the case of a listed building or when the owner wishes to retain the existing exterior, with stone walls, exposed brick, timber . A strong presence of architectural constraints can substantially increase costs, for the quantitative abundance of glass walls, bay windows, balconies . it leads to treatment of many thermal bridges and thus to a substantial increase in costs. By cons, numerous pavilions and houses are architecturally more conventional fully adapted to receive this procedure. Better, the exterior insulation can then be considered also as a complete renovation or a facelift.

Various techniques of isolation of habitat outside

Among the different isolation processes include mainly: The application of a thin coating or a hydraulic mineral coating (projected onto the wall) applied to an insulator such as expanded polystyrene or of mineral wool supplemented by a coating of a fabric reinforced with glass fibers and a coating finishing. Polystyrene can be glued to the wall, or mechanically secured.

Home insulation from the outside, the benefits

The classic example of flags whose facades are tired is a very interesting scenario: the realization of a complete thermo-acoustic insulation from the outside adds a real facade renovation. The house is rejuvenated against all colorings linked to red brown mushrooms and lichens, with tasks related to the humidity of porous walls, the spectacle of microcracks or defective external rendering. The exterior insulation does not change the living space (when we lack an appreciable space) and is realized without causing discomfort to the occupants. Do not Mess sites interiors. These aspects are of the highest order for anyone looking to protect its interior or a lifestyle difficult to repeat.

Home insulation from the outside, the disadvantages

In some cases, the formalities can be binding (permissions request form for advance notice of work or even permission). Attention increases the load factor on the ground in the field, this can sometimes be problematic in light of new regulations (Footprint concept). The price is higher than the interior insulation, but this assertion does not take into account all aspects of the facade renovation, repair of the interior, to the inconvenience or not . The solution can be difficult to implement in a complex form of old buildings or in the absence of adequate roof overhang: it requires indeed complementary to create an advanced roof and change the water recovery system Rain.
