The construction methods and associated materials very much influence the thermal performance of a building and the environmental quality in which it operates.
Unfortunately these solutions end up as bad performances and bad thermal carbon assessments.
These are the points of contact between the outside and inside of the building through a material more or less conductive so that the coolness or heat from outside can get inside the building and vice versa. By placing the insulation on the outside of the building envelope thermal bridges from the building structure can be avoided.
If one wants to achieve a very high energy performance (cf. BBC label and Passive House) this requires not only a very good insulation but also an airtightness of the building.
