Thermal insulation in one day and without building works

If the home has double partition walls (double leaf façades, façades with air cavity) or false ceilings, insulation by blowing insulating material into these cavities is a quick, economical and effective technique.
The insulating material is blown into the air cavity, filling the entire cavity and providing homogeneous insulation while stopping draughts. And it also provides sound insulation!

The solution has been used for more than 30 years and is used widely in countries with a continental climate. In the United Kingdom, more than 10 million homes have been fitted with blown cavity wall insulation. Different materials are used depending on the type of chamber and home. We can advise you on which material is most suitable for your home.

Holes are made in the brick or in the partition wall and the insulation material is blown through. The holes are then carefully sealed so that there is no sign of the operation. Holes are made all over the façade so that the insulation covers the entire wall. The insulation completely fills the air gap, leaving a layer of insulation that not only insulates but also prevents outside air from coming through the air gap.

It can be done from either the outside or the inside. In the case of flats, it is done through the inside to avoid using scaffolding and supporting structures.

If you want to install blown cavity wall insulation in your home, you need to find out if there is an air cavity in your walls.
If your home was built after 1960 and before 2006, it most likely has air cavities. If it was built after 1979, it probably has some insulation, although it is probably insufficient.
If the wall sounds hollow when you bang on it, or if when you go close to the socket (without touching it) you notice air currents, then you have air cavities.
In any case, an Iberdrola partner can come to your home to see if there is an air cavity and measure its thickness to provide you with an estimate for blown cavity wall insulation.

No. It's a simple process. It takes just hours or a day to insulate a flat. In the case of a detached house, it can take one or two days to insulate.
The operation can be carried out from the inside or the outside, provided that there is a common electricity supply for the blower. In the case of tiled rooms, it is preferable to insulate from the outside to avoid perforating the tiles.
There is no requirement for a building permit and additional equipment is only needed in the case of high buildings. In such cases, if the building residents' association agrees, the cost of additional measures is offset with the economy of scale of making the improvement jointly.

The benefits of thermal insulation continue throughout the life of the building. It needs no maintenance and there are therefore no additional costs.
Different materials are used in blown cavity wall insulation, but they all have properties or treatments that mean they require no maintenance. Thermal insulation will reduce the demand for energy in the home, which will put a smile on your face when you see your fuel bills are lower, year after year. The planet will thank you, too. What's more, it will improve your quality of life and provide sound insulation.

Iberdrola recommends glass mineral wool as the best choice for insulation, due to its superior thermal properties and durability compared to other materials.

No. It is the most economical option for reducing the need for heat and cold in a home.
It costs between around €800 and €1500 to insulate a flat. A detached home from €1200 to €2,500 or even more in the case of a large property.
The thicker the chamber, the more insulating material is needed to fill it and the greater your savings on heating and air conditioning.
It's the ideal solution if you have air chambers and gives you the best return on each euro invested in insulation.

Each home is unique. For this reason, a home visit is necessary to inspect the cavity to check the condition, feasibility of the installation and potential for improvement.
All our estimates are made to measure and after a technician's visit, since it is impossible to assess from a distance and even more so taking into account the enormous variability inherent in architecture.
The surface area of the house to be insulated tells me how “big” the shelter to be placed will be, and the size of the cavity how “thick” that shelter will be.

To ease the initial outlay, Iberdrola has agreements with lenders that will allow you to finance it. That means you can pay for your installation while you save on your bills

The amount will depend on the size of your home, the type of heating and the thickness of the cavity. In the case of a home with a gas boiler with an annual consumption of €550, saving 20% of the gas used for heating will reduce the annual bill by around €90 and prevent the emission of 240 kg of Co2 every year. If you have an oil-fired or LNG boiler, the emissions avoided will be higher.
The more you spend on heating your home, the bigger the potential savings and reduction of emissions.
If you also decide to upgrade your heating system, you can choose something less powerful, which will be kinder to the environment and make more savings.

If you have a false ceiling it can almost always be insulated. If you have air conditioning through ducts with the return without ducting, it should not be insulated. In all other cases, yes.
The larger the space above the false ceiling, the greater potential for gains there will be. We will also have to use more material to fill it, but the additional improvement will be worth the increased cost.

If the space is very large, more than 20cm, it may not be filled completely since the improvement will already be very significant without needing to fill it completely.
If the false ceiling is inclined (attic areas) it is necessary to fill it completely regardless of the space since it is the only way to guarantee that the placement of the material is correct.

These are one of the main points where heat escapes in winter and where heat enters in summer. Our technicians will advise you during the visit, but in almost all cases it should be the first point to improve.
If we have given you a quote for the façade and roof and you are not sure to what extent you wish to contract, the technician will advise you, but the general recommendation will be that we start the insulation with the roof (false ceiling or roof as the case may be).
The house may not start with the roof, but at Aislamiento Smart we do start improving efficiency from the top!

No. The glass mineral wool provides an acoustic improvement, but against airborne noises (voices in the street, cars), not against noises that are transmitted through the structure.

Usually not. The most common construction methods do not allow this. Only in exceptional cases, when we have documentation and know that it is feasible, do we isolate the party walls.

No. You can request a quote and then decide whether one, two, three, eight or all of them take up the offer. The decision will be individual and depending on the number contracted, the efficiency gain in the installation process is transferred in the form of a better price to the customers.
