Than to insulate the floor in a private house?

If the house has Underfloor heating on them comfortable to walk barefoot, especially in the cold season. There are a large number of heaters and their installation. Let’s look at what it is possible to insulate the floor in a private house.

Types of insulation

Mineral wool

One of the common insulation of the wooden floor is considered to be mineral wool. It retains heat well and can leak air, which is important since the tree has to breathe.

Disadvantage of this material – it is resistant to moisture, so when this insulation is necessary the waterproofing layer. It can be made of a conventional plastic film. After the waterproofing layer is fixed can be laid mineral wool.

It is important to leave between the boards and the insulation is a little bit of space from 4 to 6 cm, which will allow air to circulate.

Expanded clay

Concrete block – plus of this material is that it is lightweight, moisture-resistant, durable, no harmful to human and is inexpensive. Used for insulation of floors on the ground. Downside is its ability to retain heat is much lower than that of mineral wool.


Polystyrene is a dense insulation that can withstand heavy loads. Retains heat well, has a low level of water absorption.


Cellulose fibre insulation, as mineral wool is resistant to water, so before you insulate the floor in the house need to do the waterproofing layer. It retains heat well, is breathable, gives you the opportunity to breathe the tree.

Produce ecowool made from recycled paper and treated with special means to increase the resistance. It usually is not formed fungus and mold.


The foam is water – resistant, retains heat well, long service life of about 20 years. Disadvantage of this heater is that it is brittle, highly flammable and when burning harmful to human enzymes. It is best to use for insulating a concrete or brick floor.

Polyurethane foam

Polyurethane foam – this foam insulation is molecular, it is usually used for insulation of floors on the ground. Before you apply this insulation is necessary to make waterproofing layer, as it has a greater absorption capacity. And to increase the level of insulation material with both sides coated with aluminum or fiberglass.

Electric floor

Electric floor is another version of how to insulate the floor in the house. This floor is very convenient because you can regulate the floor temperature depending on the time of year or if you wish you can set automatic program. They come in several types: cable, infrared or film, deviperm, and heating mats.

Film and infrared heaters can be divided if you need a certain number of elements. Underfloor heating occurs uniformly by infrared radiation. This heater is not harmful to humans. When using it there is no dryness in the air, it is safe in case of fire, no corrosion, easy to install under any floor covering. When installing these heaters, you can not use the coupler.

Important if fails one section, the rest will work.

Heating mats

The heating Mat is a heater, as the previous is not harmful to humans. When installing it warms up the entire floor, but the coating must be with good thermal conductivity, doesn’t rust. Of the minuses – if for some reason it damaged the sensor fails the whole mechanism, not refractory.

Cable floor

Cable floor heats unevenly, to install it need a special coating, granite or tile. Subject to corrosion, fire, when using it, the air becomes dry, are harmful to humans.

When choosing a heater, try to pay attention to the service life, safety performance and features.
