Sex refers to the coldest part of the house.First of all, this is due to the fact that the cold air falls down, and from under the floor it blows. Therefore, to reduce heat losses in the house and get warmer floors, they are warmed. Especially it is required to do in premises with wooden floors. If even the boards are stacked tightly together, after a while they dry up, starts to run out of the crevices, which leads to a loss of heat of up to 30%.
We offer to consider options, how and how to insulate the floor in a wooden house from the bottom.
To insulate the floor in a private house is quite simple. For thermal insulation, you can use a variety of types of insulation.
Before you insulate the floor in a wooden house from below, you should consider the following parameters:
Warming the floor with your own hands is not difficult. The thermal insulation has three layers:
The thickness of the insulation layer is selected for each private house individually. It depends on the following indicators:
Consider how to insulate the floor in a wooden house from the bottom of the log. This method is simple enough, but very effective, which allows to eliminate significant heat losses.
Warming the floor in a private house on the lags can be as follows.
Initially, you need to install wooden logs.Then fix the boards or boards, on which the heater will be further laid. They are sewn from below or fixed to special bars. Further between the lags on the deck lay a heater, hydro- and vapor barrier layer. At the final stage, floorboards are installed and the flooring is finished.
The main advantage of floor insulation on the lag is the simplicity of the work, almost everyone can cope with it, while efficiency is at the highest level.
To date, the market for building materials offers a variety of different thermal insulation materials, which differ among themselves in their properties, size, method of application and cost.
What is better to insulate the wooden floor? Warming can be achieved by using insulating materials, which are used for thermal insulation of roofs and walls:
Also used materials such as expanded clay, sawdust, foam. The choice of a suitable seal depends on the different parameters, preferences and capabilities of the owners of this housing.
Sawdust belong to one of the simplest speciesinsulation. Their main advantage is rather low cost (in comparison with other heat-insulating materials), ease and simplicity of backfilling, which allows to insulate even hard-to-reach and very narrow places. In addition, sawdust refers to environmentally friendly materials. They can be used not only in pure form, but also be included in various construction mixtures.
Warming the floor in the old house is possible with mineral wool, which refers to one of the most common heaters. Its main advantage is absolute incombustibility. It also has:
Before you insulate the wooden floor from below with mineral wool, you should familiarize yourself with its shortcomings. These include:
In addition, this material is not safe for the human body.
Mineral wool is produced in the form of solid platesor flexible mats. The harder side of the plates is denoted by the blue stripe. The installation must be carried out so that the marking (strip) is at the top. Plates, as a rule, are used for thermal insulation of wooden floors. Put them in one layer.
Penofol refers to one of the new multilayeredrolled thermal insulation materials, which appeared on the construction market very recently and has not yet managed to get widespread. It consists of a heater and a special reflective layer (thin polished aluminum foil). Almost any insulation can serve as a basis (warming material). The most popular is a translucent material, to which foam polyethylene belongs.
The classical version of penofol isPolyethylene foam, thermally bonded with foil. But such an option can not meet all the existing needs of modern construction, so at the moment there are many varieties of penofol.
Penofol classic has a high density, due to which it is able to withstand large mechanical loads.
The material can be used both for the main heat, steam and waterproofing, and as an auxiliary insulation, in combination with another insulation.
Due to the small thickness and the presence of foil assemblyis simple, easy and fast. Heat insulation can be laid on the floor surface by butt or overlap. The formed joints are sealed with a metallized tape. The use of foam foam eliminates the need for steam and waterproofing. This function is performed by aluminum foil.
Styrofoam (foam) also takesthe leading place among heat-insulating materials. This is explained by the presence of a number of advantages and a minimum of shortcomings in the material. The insulation has a low thermal conductivity and vapor permeability, high strength, fire resistance, biological and chemical resistance. Due to the cellular structure, the insulation is durable and very effective as a thermal insulation.
The disadvantage of expanded polystyrene - absorbency of moisture, because of what certain of its properties are lost.
Ecowool is made of natural materials.On 75% it consists of paper and 25% - from natural special additives. It is a mixture of cellulose, and the binding components in it are boric acid and antiseptic lignin. Due to this composition, ecowool is absolutely safe for humans, and is also environmentally friendly.
Its advantages include lowheat conductivity, fire safety (the material does not burn, but only smolder), the ability to restore heat insulation properties after wetting. To disadvantages, the cost is higher than that of other heaters.
How to properly insulate the floor with wooden ecowool? It is applied in various ways:
Isolon is a thermal insulation material,made of foamed polyethylene foam. The insulation was designed taking into account the current requirements for thermal insulation. Due to this, its use has several advantages.
First of all, it is necessary to note a small thicknessmaterial that ranges from 2 to 10 mm. The thermal conductivity does not increase. Isolon with a thickness of 1 centimeter for thermal conductivity is equal to the brickwork.
Isolon due to foam polyethylene is notgets wet. The material is durable, does not rot, protects from steam and moisture. Insulation is ecologically safe, it can be used in any premises. Such a material can be used for both basic and auxiliary thermal insulation. Isolon when processing wooden floors serves not only as a heater, but also plays the role of noise insulation, as it can absorb sounds. Another advantage of this material is its small thickness, which saves space.
Polyurethane foam has a cellular structure, in whichpores are filled with insulating gases and air, which allows to ensure low thermal conductivity and at the same time a small weight of the material. Therefore, polyurethane foam is considered one of the best thermal insulation materials. Its strengths include resistance to alkalis and acids, to decay, mold damage.
How to insulate the wooden floor from belowpolyurethane foam? The material is applied to the surface by spraying, for which purpose special equipment is used. This insulation is quite well adheres to different materials, so it can be used for thermal insulation of any surfaces. This method allows to warm the surface of absolutely different shape and complexity, repeating with accuracy all contours and thus not forming joints. Due to the low moisture absorption coefficient, there is no need for a vapor barrier layer device.
Warming of the floor is an important stage in keeping the heat and maintaining a favorable atmosphere in the house.
If you are thinking how to insulate an old wooden floor and are going to make a purchase of a material, you need to take into account all the factors, determine the priorities, and only after that make the final choice.
