1.1.11 Adding a low Emissivity (E) window film

1.1.11 Adding a low Emissivity (E) window film Description A low E film is an extremely thin layer of metal oxides, in the order of nanometers, which, if it is applied on the glass, provides a capacity of reinforced thermal insulation. The film reflects inward a part of the incident long-wave energy (heating), [...]

1.1.12 Adding a solar control window film

1.1.12 Adding a solar control window film The solar control film, easily applicable on window glasses, has the property of reflecting part of the solar radiation received, decreasing the amount of energy that passes through the glass.   Benefits Solar films block 99% of UV light that fades [...]

1.1.13 Put foil behind radiators to avoid heating the wall

1.1.13 Put foil behind radiators to avoid heating the wall Description Silver foil placed in the back of a radiator will reflect heat back into a room rather than letting it uselessly escape through the walls of a house. Benefits The energy savings will not be significant, [...]

2.1.1 Adding or increasing external insulation in walls

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

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

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

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

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

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 [...]
