Building insulation

  • Exterior walls

Heat loss can be avoided with good insulation. In general, thermal insulation products are mineral or organic in origin: fibre glass, pumice, cork, vermiculite, polystyrene, polyurethane and perlite. Depending on the case, these can be used loose or as foam, rigid panels, mats or felt.

One of the most appropriate insulation systems for exterior walls is external insulation. This consists of fixing sheets of insulating material on the outside of the walls and covering them with a new coat of plaster.

This type of insulation allows, first of all, eliminate heat bridges caused by beams or pillars, thus preventing the formation of mould from condensation. Secondly, it reduces variations in temperature, improving the building’s thermal capacity

Summer air-conditioning is a comfort requirement that is used in many countries with hot spring and summer periods. The most used systems in Europe are:

  • Centralised ventilation, cooling systems Ventilation and heat recovery
  • Independent air-conditioning appliances


Traditional incandescent light bulbs generate less than 10% of the electricity they use: the rest is needlessly lost as heat. In low consumption fluorescent lamps this ratio is inverted, as they convert  90% of the consumed energy into light.

In an apartment, just replacing the three most used incandescent light bulbs by three low consumption light bulbs, can lead to 75% lighting electricity savings. The replacement of one LED will save 80 % of the consumption of one fluorescent lamp
