Guide to buying a thermal insulator

If you are looking to save money on heating and improve insulation in the home or car, it is necessary to use thermal insulation, which allows a warmer environment inside the space. Currently, there are many models available, but for one to be considered quality, it must meet certain standards. Therefore, we invite you to read the following guide to buy the best thermal insulation on the market.

Shopping guide

Manufacturing materials

If you want to know how much thermal insulation costs, you should analyze what materials the manufacturer used to make the product. In general, the higher density they are, the higher their price. Among the most common materials, insulators can be found that are made of polyester, foam glass, cork, resin foam, mineral wool, wood wool slabs, wood fibers, blown cork, polyethylene and silicone, while others incorporate rubber, as well as other dense materials that do double duty.

According to the materials, a model will be more or less suitable to install in the rooms, according to the heat tolerance. For example, there are designs that are suitable for installing in windows, while others are suitable for placing on walls, the objective being the same, but on a different scale.


According to the needs, it is necessary to select a style. Beyond the fact that it is a good and economical thermal insulator, it is necessary to analyze if it will serve the purpose that is being sought. For example, in the market you can get some options that are suitable for horizontal walls and others for vertical walls.

Similarly, it is also possible to get some designs that are practical to isolate small holes left in doors and windows. Meanwhile, some are of a film style that seeks to cover the windows to improve thermal insulation, without compromising visibility.

isolation level

The most important thing in a thermal insulation is that it fulfills the function of preventing the cold from entering or the heat from leaving the room in order to keep it warm. So, before buying, you need to make a comparison of thermal insulators based on this property.

The level of insulation must be high and in many cases this is due to the thickness of the panels and the materials that have been incorporated, which creates a dense layer that prevents the entry of cold air. In addition, it is also important that when making the selection you look for options that incorporate greater versatility.

For this reason, some manufacturers offer alternatives that not only insulate the cold, but also serve to prevent sound or that fulfill a double function, being suitable for maintaining both hot and cold temperatures.


Thermal insulations are available in different colors. At first glance, the tonality may not represent a problem. However, it can be depending on the type of insulation. If this layer of thermal insulation goes under the concrete or concrete, there will be no problem with the color. Now, if it is a film that will be placed on windows, it is recommended that it be transparent so that it prevents visibility. On the other hand, if it is an insulator for a car or external wall, it should be in neutral colors such as grey, beige or black. 


According to the type of thermal insulation, the installation process changes. For example, on the market you can get some models with an easy-to-install system that only requires adhering to the surface with a little pressure, because they include strong glue that helps the sheets to stick to the surface efficiently.

Similarly, some models are equipped with double-sided tape, whose function is to stick the insulation. On the other hand, there are models that can be placed behind the radiators in a simple way.

size and presentation

Thermal insulation is available in different presentations and sizes that are suitable for different surfaces due to their dimensions. Some models come in rolls and are convenient for insulating a van in one package. Similarly, there are other models that are designed in the form of panels, as well as others that look like tapes, also called weather stripping. Other insulations come in foam form.

On the other hand, in relation to size, there are options that come with the specific shapes of the windows or that give the user the possibility of cutting them, without losing the excess part, so that it can be used in another space. The important thing in this aspect is knowing how to take advantage of the sizes based on savings.

Frequently asked questions

Q1: Which thermal insulation is better for sheet metal roofs?

Insulators for sheet metal ceilings can be of different types and provide a high degree of thermal resistance. The intention with these insulators is that they have a low degree of humidity so that the heat does not pass through. Hence the need for them to be made of porous materials that immobilize dry air. For this reason, the most used materials for these ceilings are crushed cork in the panels, being a kind of agglomerate. Also, there are those who recommend using wood fiber, cellulose or wood wool insulation.

Q2: How to safely renew a corrugated iron thermal insulation?

The uralite ceilings are not a good option when it comes to insulating the cold or heat. There are those who recommend that fiber cement ceilings be insulated from the outside or inside. In both cases, it is a high investment and with jobs that can be annoying.

In addition, it is appropriate that they be executed by professionals. In the case of insulation from the outside, it is appropriate to reinforce the roof with a thermal insulator that supports adverse weather conditions. Internal insulation requires troublesome work and involves a loss of at least 10 centimeters in height. Beyond these options, the recommendation that remains is to remove the entire roof and opt for another material.

Q3: How to make a domestic heat insulator?

Keeping the temperature of the home warm allows you to enjoy a comfortable, safe stay with a pleasant climate, hence the importance of insulation. There are a few methods for making home insulation, as well as techniques that save some money naturally. One of them is with ground recycled newspaper.

Borax salt must be added to this, so that it behaves in a similar way to wood and turns out to be an insulator with a high capacity for storing heat on cold days. It is recommended that this insulation be added in cavities such as false ceilings. Similarly, cork is another material that can be used successfully and is suitable for summer, because it has the ability to retain freshness.

Q4: Which is better, glass wool or thermal insulation?

Any insulation that is used is convenient to provide more comfortable and warm rooms on cold days or to provide freshness on hot days. In the case of glass wool, it is a type of thermal insulation that is made up of many agglomerated glass filaments and serves to transmit heat.

In fact, it is one of the most widely used and recommended because it is convenient as an acoustic for ceilings, walls, floors and others. Also, it is a light insulator with which energy can be saved in air conditioning spaces, and it is also a recyclable, non-polluting or non-toxic alternative, so it is not harmful to health. All this leads us to conclude that it is one of the best thermal insulators that can be obtained on the market.

Q5: Is it suitable to use cardboard as thermal insulation?

Cardboard is an alternative that is usually used as thermal insulation and its use is appropriate. However, its effects are not the most efficient and will depend on the type of cardboard, the treatment that has been applied to it and the place where it will be placed. These variants will affect their insulating effect to be greater or lesser. The ones that work best are usually honeycomb cardboard and xanite cardboard.

Q6: What advantage does vapor barrier thermal insulation provide?

The vast majority of thermal insulators have a vapor barrier, such as polyethylene sheets, a
