2.1.1 Adding or increasing external insulation in walls Description External Thermal Insulation Composite Systems (ETICS) in retrofitting projects consist in adding a surface layer of thermal insulation (EPS, XPS, glass wool, cork…) externally attached (stuck, plastic pins and profiles) to the façades and visible party walls, to then protect the insulation using [...]
2.1.2 Adding or increasing internal insulation in walls Description The internal insulation system is based on the placement of thermal insulation in the internal layers of facades and party walls to coat after with a new internal finish, usually of plasterboard panel, or cladding finish of hollow brick. This system leaves out [...]
2.1.3 Adding insulation in air chambers of walls through injection Description In the case of the existence of air chambers in the thermal envelope of the building to retrofit, it is possible to fill these chambers with thermal insulation. The most common methods are the injection of polyurethane (PUR) foam and cellulose. [...]
2.1.4 Installation of a ventilated façade Description It is a double façade system provided with an external coating fastened with metal profiles to the internal part of the enclosure. Between both, there is an air chamber partially filled in with thermal insulation. The ventilation is raised through top and bottom openings or [...]
2.1.5 Adding or increasing external insulation in roofs Description This measure consists in adding a layer of insulation to the exterior face of the roofs with the object of reducing their thermal transmittance. The measure is of great interest for 1 or 2-storey buildings. It should be initially rejected for high-rise buildings [...]
2.1.6 Adding or increasing internal insulation in roofs Description The insulation from the inside is achieved by insulating the roof of the building or the ceiling of the upper housing in case it is a multi-family building. It is a simple execution and it allows the use of thermal insulation materials of [...]
2.1.7 Adding or increasing external insulation in floors Description This measure consists in adding a layer of thermal insulation to floors with the goal of reducing the thermal transmittance. This measure is of interest for 1 or 2-storey buildings for enclosures that are in contact with permanent occupied spaces. [...]
2.1.8 Adding or increasing internal insulation in floors Description This measure consists in adding a layer of thermal insulation to the internal face of the floors with the goal of reducing the thermal transmittance. This measure is of interest for 1 or 2-storey buildings. It is a simple implementation work and it [...]
2.1.9 Installation of efficient windows (double glazing with aluminium frames with thermal break) Description This measure consists in the replacement of inefficient windows (e.g. aluminium frame without thermal brake and single glazing) for an efficient one with double glazing and aluminium frames with thermal brake. A typical transmittance of this type of [...]
2.1.10 Installation of efficient windows (double glazing with wood frames) Description This measure consists in the replacement of inefficient windows (e.g. aluminium frame without thermal brake and single glazing) for an efficient one with double glazing and wood frames. A typical transmittance of this type of windows is between U=1.9 W/m2K and [...]
