What is the best type of underfloor insulation?

Moisture insulation for floors

A very cold floor is often synonymous with a cold, uncomfortable interior of a house. The solution is to insulate the floor of the house. For this you will have to ask a professional for a project of reform of your house.

It is also important to insulate the floor from humidity, in case this problem is present. The best solution is to waterproof the floor with an asphalt sheet, with butyl, …, under the screed layer and put a ceramic floor.

The room will heat up faster when the heating is running, and cool down faster when the heating stops. The laid insulation will affect the floor level, reducing the volume of the room, making it difficult to open doors, stairs and other accessories. The most commonly used solution in this case is phenolic foam, as it can achieve good thermal insulation in less depth.

It is generally better, especially in a south-facing room, as the concrete helps absorb heat and limits overheating. In this case, the thermal insulation goes on top of the waterproofing membrane; the concrete is poured on top.

What is the best thermal insulator available?

Expanded polystyrene has high thermal resistance and thermal conductivity, is a lightweight, water and shock resistant material, easy to handle and install. It has a great performance as a thermal insulator for roofs, floors and facades.

How to insulate the floor of a house?

The most common is to use a specific floor insulation. This is an underlayment that is placed under the final floor of the house and has a high thermal resistance and waterproofing and anti-condensation properties, making it very effective.

What is the best thermal insulation for walls?

The best thermal and acoustic insulators

In this case, we highlight fiberglass. This insulating material is used with a higher density in areas that require greater resistance to compression. This is the case of floors or facades, to give you a practical example.

Thermal ceramics for floors

The correct insulation of floors greatly improves comfort in the home, as well as its energy performance. The cold floor effect is very unpleasant for comfort, as the natural temperature gradient from floor to ceiling is enhanced. The cold air from the floor does not mix with warm air from other sources, such as heating or cooling.

hot air from other sources, such as heating or air conditioning, because the hot air rises up to the ceiling, and the cold air stays below. This temperature gradient is negative for the comfort of the inhabitants. In other words, it is very difficult to heat the floor, as the warm air tends to rise.

It is also an effective solution for floors in buildings with a wooden structure, where the floor is also a platform and has a large air chamber that can be blown in with our usual technique.

The ideal situation is that the floor has an air chamber underneath, such as a wooden floor on battens. Using the blowing technique, careful perforations are made through which the insulating material is introduced.

What is the best roof insulation?

Among the most efficient thermal insulators for sheet metal roofing are the following: Expanded polyurethane, sheet metal roofing paint, glass wool and styrofoam roofing sheets.

What is the best blown-in insulation?

In short, the most suitable materials are EPS beads and rock wool or mineral wool (glass wool or fiberglass). EPS beads adapt a little better to small cavities. The use of cellulose is not recommended and polyurethane foam should not be used under any circumstances.

What is the best thermal insulation for wooden houses?

Polyurethane: This is the material that can best insulate your wooden house, but its origin is totally petrochemical, it has a high chemical load and its manufacture involves the expenditure of a lot of energy. It comes in the form of sheets or polyurethane foam.

Thermal insulation for floors

In construction there are several insulating materials that can be used when making repairs, building a house or any type of building. It will depend on the needs, the type of insulation to be used.

But that is not all, noise from neighbors, humidity, pipes or electrical circuits are other important factors to protect those who live in an apartment or house.

By having the characteristics mentioned above, mineral wool focuses on improving the quality of life of people -in their home or other type of construction- and at the same time providing them with safety.

How to insulate the floor without building work?

It would be better to use natural thermal insulation. For example, wood fiber or mineral wool insulation is almost as good an insulator as EPS. Cellulose is the ideal insulation if it does not have to be load-bearing. Granulated cork is also used.

How to insulate the floor of a second floor?

To improve insulation in second floors with porches, cellulose must be injected from the outside. In this process, the perimeter is closed to prevent drafts and, after opening hatches from the porch, the cellulose is injected.

How to insulate a house from ground moisture?

The best thing to do is to pour a layer of gravel to prevent water from rising to the pavement, you also have PVC vaults that leave a ventilated chamber under the floor that prevents moisture from rising … it is more expensive, but more effective.

What is the best thermal insulation

Insulation reduces heat loss and leakage in winter and overheating and hot air ingress in summer. The choice between the different types depends on the area to be insulated (interior walls, facades, ceilings or under roofs) and the type of installation.

Solutions from the outside require a waterproof material, such as extruded or expanded polystyrene, or an air chamber that allows drainage and ventilation of the insulation; this insulation is placed inside a structure and covered with panels.

What does the R of the insulation mean: it is a characteristic of the materials, which measures the resistance of the material to the passage of heat: the higher the value, the greater the insulating capacity of the material. This thermal resistance is measured in m2*k/W and relates the thickness of the product and its thermal conductivity (λ).

Lambda λ indicates the thermal conductivity of a material. It is independent of thickness and depends only on the type of material. The lower it is, the higher the insulating capacity of the material. Insulators have λ = 0.028 -0.040 approximately, it is measured W/m*k. Another data to take into account is the thermal transmittance (U) which is measured in W/m2*k. It is the amount of heat that passes through a material or a series of materials (wall). In the case of a wall it is the sum of the thermal resistances of all the materials or layers that compose it.
