How to Heat a Very Cold House

Little by little, winter is approaching, temperatures are getting lower and our houses are losing temperature. As a result, we begin to need the heating to be on for more hours and, therefore, gas, diesel and electricity bills rise steadily.


Normally, those who consider acquiring a rug will base their choice on the beauty, material or form of knotting. Very few people will take into account the insulating capacity of a carpet when buying it.

Buying a carpet with high density is synonymous with having a great thermal insulator for our home. The denser the carpet, the more fibers it will have in less space and, consequently, the thermal insulation will be greater and more effective.

In addition to density, we must consider the material of the carpet. Knotted wool is as effective as thermal insulation that synthetic materials have been created imitating this property.

Once you have chosen the carpet you will wonder how and where to place it so that the ability to thermally insulate is as large as possible. An option that never fails is to place it on the floor of the room, avoiding unpleasant contact against the cold floor in the morning. However, another option is to place the carpet as a tapestry, in an upright position. This form is a beautiful, insulating and eco-efficient solution for exterior walls, which have little thermal insulation.

Now that you know, if you are considering buying a carpet, do not forget that it can also be a great thermal insulator that allows you to obtain great energy and economic savings.

Gaskets and under doors

Both weather-strips and under doors are ideal elements to thermally insulate the home. The weather-strips, of different materials and features, for sliding and sliding doors and windows are incorporated into the window or door opening you want to cover. Whether they are foam, rubber, silicone or brush, they all effectively fulfill their insulation function. On the other hand, the under doors cover the gap between the floor and the door. 

Weather-strips and under doors are a quick and economical solution to improve the insulation of windows and doors. It has been found that placing these materials in the gaps of doors and windows to avoid leaks and improve insulation can provide up to 30% energy savings. In addition, the installation is very simple. Except for the swinging seals, which are screwed to the doors, all other types are self-adhesive.

Gaskets, under doors and carpets are thermal insulators that, logically, do not require an integral reform. However, if you have to undertake a home renovation and want to insulate it to improve thermal comfort, also, in this post, we want to give you some tips to choose the best thermal insulator for your home.

Multilayer reflective insulation

You probably won’t know that this material was developed by NASA for spacecraft and satellites. It is considered by professionals as the best thermal insulation, both against cold and heat. The multi-layer reflective insulation can be installed on facades, ceilings, roofs and floors. It can also function as a thermal insulator for windows.

This type of insulator has many advantages. Among them are its low thickness and the consequent gain of space in a home, flexibility (adapts to all corners and encounters), its ease of handling and that does not affect humidity. In short, the multilayer reflective insulation is ideal for use in renovations and renovations.

Expanded and Extruded Polystyrene

This material, better known as white cork, stands out for its use as a thermal insulator. It is a very light insulator, very easy to transport and install. On the other hand, it prevents the appearance of fungi and bacteria, they can be recycled easily, and they are very durable materials.

However, many professionals claim that by absorbing moisture, the material loses effectiveness. In turn, it is not a flame-retardant material, so it does not protect against fire.

On the other hand, extruded polystyrene, despite having a composition practically identical to that of the expanded one, has greater thermal resistance, is more rigid and less flexible.

Projected polyurethane

Also known as polyurethane foam, it is a thermal insulator that is used in construction. When projected in the form of foam, it allows all holes and hard-to-reach places to be completely covered and insulated.

In relation to water resistance, the projected polyurethane foam has impermeability properties, since it allows the perspiration of the enclosures, exposure to moisture does not usually affect it and hinders the appearance of bacteria or fungi.

However, the projected polyurethane has drawbacks. As it is a combustible and difficult to install material, it is beginning to be less and less used when it comes to thermal insulation of homes.

Glass wool and rock wool

These 100% recyclable materials are very commonly used to carry out thermal insulation in all types of buildings and homes.

Unlike the aforementioned materials, wool, both glass and rock, have the property of fire resistance.

Between the two wool they differ in that, while glass wool is putrescible, rock wool can sometimes be affected by the appearance of mold, fungus or other bacteria.

Likewise, it should be considered that there have been situations, although unusual, in which there has been skin irritation, allergies or other health-related problems. In turn, rock wool entails a significant loss of habitable surface.

Have you noticed an increase in your bills? Are you thinking of carrying out a reform and want to take the opportunity to thermally insulate your home? Take advantage of our tips to insulate your home and see how you start saving. And if you know other more effective thermal insulators, let us know through the comments. Insulate your house and you will save!
