Thermal insulation for the home: save maximum energy

thermal isolation

Many people focus on simply purchasing efficient stoves or air conditioning systems, or installing smart thermostats, and believe that is enough to save energy. But most forget something cheap, and that can make a big difference: thermal insulation.

Thanks to this isolation, it will be possible keep your home both cooler in summer and warmer during winter, so your climate equipment will have to work less, saving a good portion of electrical energy, thanks to its double benefit, isolate from the outside and prevent leaks to the outside.

Best thermal insulation for home

Among the recommended products, we have the heat shields to put behind radiators, or between systems that emit heat and air conditioning systems, to improve their effectiveness:

If what you are looking for is a thermal insulation for walls or floors, the options go through these others:

As well you have curtains that insulate against cold and heat quite effectively, both for doors and windows:

isolations for doors and windows, to prevent the slots from letting energy in or out:


Properly insulating your home is a fundamental investment to improve comfort, reduce energy consumption and save money on bills. However, choosing the best insulation for your home can be a complex task, as there are various materials, thicknesses, and installation systems available. To choose the right one, you have to Keep these considerations in mind:

  • Climate of the area: The type of climate your home is in is a crucial factor in determining the type and thickness of insulation needed. Areas with cold winters and hot summers will require a higher level of insulation than areas with temperate climates.
  • Characteristics of the property: the typology of the construction, the orientation of the home, the existence of thermal bridges and the surface to be insulated are aspects that must be taken into account when choosing the insulation. Generally, in modern apartments and homes, the insulation is de facto worse than in old houses, with stone walls and very thick walls. For example, while in modern homes you may be interested in insulating more walls and floors, in older homes the weak point could be in the doors and windows.
  • Budget available: Thermal insulation has variable prices, so it is important to establish a budget before starting the search.
  • Energy efficiency: It is important to opt for materials with high energy efficiency, which guarantee good performance and contribute to energy savings. There are various insulating materials available on the market, each with its own characteristics and advantages:
    • Mineral wool: a versatile and efficient insulating material, available in the form of panels, blankets or loose. It offers good thermal and acoustic insulation, is fire resistant and is not hygroscopic (does not absorb moisture).
    • Expanded polystyrene (EPS): It is light and economical, popular for its ease of installation. It is a good thermal insulator, but less efficient than mineral wool and not as fire resistant.
    • Extruded polystyrene (XPS): an improved version of EPS, more resistant and durable, with greater insulating capacity and greater fire resistance.
    • cellulose insulation: It is a natural and ecological product, based on recycled paper. It is a good thermal and acoustic insulator, and regulates environmental humidity.
    • Cork: can be both artificial and natural, with excellent thermal and acoustic insulation properties. It is a breathable and resistant material, although it can be expensive if it is natural.
  • Insulation thickness: the thickness of the heat shield will depend on the factors mentioned above, such as the climate, the type of home and the insulating material chosen. In general, a minimum thickness of 5 cm is recommended for good thermal insulation for intense climates.
  • Installation systems: There are different installation systems for insulation, depending on the type of home and the insulating material chosen, such as blown-in systems for ceilings, cavities, walls, etc., the panel type that is embedded or screwed, and the one designed for very large roofs. , such as facades, roofs, etc., and there are even self-adhesive ones, for easy installation.
