Warming of the floor in a wooden house from the bottom: the materials and installation technology

One of the most common and important problems of a private house of wood is a cold floor. This is due to the outflow of cold ground air streams which penetrate through the cracks. So the room was warm and comfortable floor insulation must be carried out in a wooden house at the bottom. To learn how to do it, what materials are used for this purpose and highlights installation work described in this article.

Why do I need to do a floor insulation in a wooden house from the bottom

Warming wood floors in a private house in a technically correct to hold the bottom, which is due to several reasons:

• This avoids changes in the size of the room height on the ground floor;

• no need to choose a hard insulation that withstands the weight of furniture and home appliances;
• thus protects the owner from freezing all the hardwood floor;
• reduced sedimentation condensate line outside the structure. This helps prevent the decay of the whole house.

Nuances of warming the floor in the house

The choice of materials and methods of floor insulation in the house is totally dependent on the design features of the structure, individual capabilities and preferences of the owner. Be sure to take into account the nuances of the installation and the specific operation of the wood itself.

Houses made of wood can be:

• frame type;
• on screw piles;
• on strip foundations;
• on pile foundation.

No matter what type of a structure, insulation of the wooden floor in a private house has a common specific nuances:

• use waterproofing - a mandatory necessity. This will prevent the swelling of the boards. The best material for waterproofing is unilateral fiber;
• to provide heat in the room to do a two-layer insulation of the wooden floor below in a private home. In such buildings flooring consists of tightly fitted to each other boards. This material was subjected to constant to temperature extremes and moisture. Therefore wood floor necessarily subjected special means;
• insulation performance should not vary by contact with the wood.

All of these points should be observed during the warming of the floor in the country and in the private country cottage.

Materials for thermal insulation of the floor in a private house

The construction market offers a wide range of materials for insulating floors. They vary in cost, technology of installation work, the optimal operating conditions, etc.

The materials used for thermal insulation of the floor in a wooden house from below:

• mineral wool;
• keramizit;
• penofol;
• foam or expanded polystyrene;
• sawdust;
• penoplex;
• ecowool.

Each material has its advantages and disadvantages. His choice as a heater depends on the characteristics of the house, the financial capacity of the owner and the type of flooring.

Features floor insulation Penoplex

Penoplex is conventional foamed polymer. It is characterized by high strength, the ability to maintain good form. For production Penoplex used extrusion method. This allows you to get a solid structure with a large number of small cells inside for better heat transfer. Inside the holes did not penetrate the moisture, so the material does not require additional waterproofing. Penoplex not put a strain on the structure of the foundation. Thanks to this feature of the material, most often it is used for thermal insulation in the floor frame house on stilts.

Mineral wool

Mineral wool as an insulation is used more often. It is lightweight, does not burn, has a high degree of protection from outside noise.

There are three kinds of material:

• glass;
• slag;
• stone.

This material is produced in the form of a dense board or a flexible mat. For ease of mounting plates is marking a blue stripe. This allows to place the sheets in the desired direction.

The big drawback of this material is the ability to absorb moisture. Therefore, when the insulation of the floor in a private house with his own hands need to hold good vapor barrier.

Useful advice!Working with cotton requires special protective clothing for the body, gloves and glasses. This is due to the fact that when carrying out installation work on small plates separated fibers. They can cause skin irritation and itching.

Warming of the floor expanded clay

LECA is a small round spheres of porous clay or shale. They are obtained by firing material in an oven at high temperature. Expanded clay is considered to be a safe and environmentally friendly material. Among its advantages should be highlighted:

• high sound insulation;
• resistance to low temperatures;
• environmental protection for human health.

Notable drawback of this material is a seal under its own weight. Expanded clay balls are pressed together. This increases the weight of the substance and reduce the insulating properties.

Useful advice!It is not necessary to choose the material for insulation of the floor in a wooden house on screw piles. Increasing the mass of flooring may lead to loss of the foundation structure.

Using sawdust for insulation of floor

Sawdust - waste products of the woodworking industry. They have good sound insulating properties of steam and retain heat, environmentally safe for humans. Sawdust different low cost. The resulting thermal effect is no worse than the expensive materials. Due to the cement component is well suited even for warming the floor in the ground floor apartment. Subsequently, a tie can be done laying the laminate, linoleum, tile, etc.

Before using the dust is subjected to special treatment. This helps prevent the appearance of these rodents and bugs. After they are mixed with cement and water and applied uniformly to the whole area of ​​the flooring.

Useful advice!Instead of clay, you can use the solution. This material is environmentally friendly and has better insulating characteristics than cement.

Sawdust is ideal for thermal insulation of floors on the ground, especially if the building does not have a strong and solid foundation.

Floor Warming foam

Popular floor insulation with polystyrene foam. Most often, this material is referred to as foam. Advantages of the insulation:

• steam and low acoustic permeability;
• low thermal conductivity;
• resistant to external factors and chemicals;
• It does not lose its properties over a long period of time;
• easy to install.

A significant disadvantage of the foam is its exposure to moisture. It can absorb it into himself. This negatively affects the basic operational characteristics. So he is afraid of exposure to fire and high temperatures. And here is a simple and inexpensive technology polystyrene insulating floors is its great advantage. That is what, in most cases, and the owner of the house is oriented.

Useful advice!If your cottage or private house is located on the ground with shallow groundwater, or at high risk of flooding, you should not choose foam as insulation. If the choice has already been made, it is necessary to take care of a good waterproofing.

Ecowool

Penopoliuteratnovaya foam (ecowool) - a great way to solve the problem of warming the floor in an apartment on the ground floor private house (dacha). This material is blown into the free space by the compressor. So it uniformly fills all voids. Fine particles consisting ecowool, provide excellent vapor barrier. The material is not exposed to moisture, so additional waterproofing is not needed during installation. This reduces costs for warming.

After solidification the solid obtained even layer. It is perfectly withstands the load. Light weight does not increase the weight of the structure. The service life of the heater - for more than 20 years.

Ecowool significant drawback is the need to use a special industrial equipment.

Useful advice!Professionals say that the waterproofing is not needed for insulation of this material. However, when the floor warming cottage foundation without additional waterproofing layer is better to build.

Penofol: insulation for floors

The combination of foamed polyethylene and a thin layer of aluminum foil is called penofolom. It is sold in the form of rolled coil. The thickness of the seal 3 to 10 mm. Penofol retains heat well, is environmentally friendly, has high soundproofing.

The big drawback of this material is exposed to moisture due to the presence in the aluminum foil. Another negative - penofol no different long-term use. Five years later, it is necessary to carry out the re-warming.

Highlights of the installation work

All used materials for thermal insulation of the floor have their fastening methods. However, there are highlights of the thermal protection device. It is recommended to observe the installation of any material.

The order of the main layers in the device insulation of the floor in a wooden house with his own hands:

• waterproofing layer;
• layer of insulation;
• vapor barrier material;
• direct structural overlap of the elements;
• flooring.

Experts say that such an arrangement will provide essential layers inside the room optimal thermal conditions. This technology preserves the necessary moisture circulation in the house.

Useful advice!In basement floor insulation in wooden house can be chosen with the cross beam 50 to 100 mm. They reinforce the bottom, and is laid between the insulation layer. In addition, the resulting "cake" to be sewn planks.

waterproofing

At warming the floor in a private home can not do without waterproofing. Because of the ability of cold air to condense on the surface of the warm, wooden flooring is affected by moisture. Her constant presence in the room leads to the active development of fungus, mold and causes rotting of the structure itself. Especially if special funds are not used in the construction of the house.

When laying a waterproofing layer insulation without the influence of moisture adversely affects the conductive properties of the material. Result - increasing humidity and temperature reduction. Waterproofing helps to avoid unpleasant moments data.

Waterproofing layer is laid from the effects of cold air flows.

laying a vapor barrier

Human warmth and worked in the house of the equipment highlights the warm air. It passes through the overlap and collide with cold air condenses. The problem of this phenomenon lies in the fact that there is settling of moisture inside the structure. As a result, wood swells and begins to rot from within. To prevent this process by treating special means will not work. Therefore, when the insulation of the floor in a wooden house or other bottom Penoplex presence of vapor barrier material is necessary.

When carrying out installation work from below, and vapor control layer is laid first. The simplest and most accessible material for this purpose is a polyethylene film. It is ideal for steam and waterproofing.

The presence of such layers in the floor covering should be designed in advance. If this was not done in time, it is necessary to pave the film immediately after entering the house in operation.

Useful advice!An excellent material for hydraulic and vapor barrier are moisture-windproof membrane. This material allows air to circulate inside and retards moisture from it. It can be used for insulation of the floor penofolom or other insulation.

The main stages of the insulation pads

The best option is the installation of a floor laying insulation on logs. These transverse boards are used for subsequent Coanda flooring.

The main stages of work:

• on foundation laid installing lag. The recommended distance between the beams is not more than 1-1.2 m;
• then conducted the installation of thick plywood or chipboard sheets. They are secured by screws. So preparing the foundation for the construction of a thermal insulation layer;
• between the timber joists is laid insulation. Depending on the material used, the thickness of this layer may be different. In any case it must not exceed the dimensions themselves lag;
• further waterproofing layer is laid. Although this step is recommended by experts for maximum effect, it can be skipped. This is due to the stability of some materials to moisture;
• It can now be laid flooring. It may be old. A can be replaced by a new one.

Compliance with this sequence will allow for warming of the wooden floor Penoplex or other insulation.

Features sawdust insulation

Warming of the floor with sawdust - eco-friendly and affordable way to keep warm in the house. If you choose this heater must adhere to a number of recommendations:

• in the prepared mixture of sawdust with cement or clay, you need to add the broken glass. This will avoid the appearance of rodents. Do not forget to use special solutions;
• mixture consists of five parts sawdust, one part cement (clay) and half of the water. This proportion must be observed. Mixing steeper solution you get a solid insulation, but with low thermal conductivity;
• carefully fill the void between joists. This will give an even layer of insulation. If you do not withstand this technology, thermal insulation is "leaky", and the floor will remain cold.

Useful advice!Because of the commercial availability of a large quantity of insulating material and time costs for preparing a mixture dust rarely used for insulation. However, they will help to solve the problem of isolation, with limited financial budget.

Features warming Penoplex

Due to its high durability and an affordable cost, insulation Penoplex floor in a wooden house is more common to other materials.

Among the features of the installation of the heater should be noted the following points:

• penoplex fit between joists and secured to the floor below the mounting adhesive;
• must be accurately and tightly customized plate edge. This will prevent the penetration of cold air;
• additionally glued joints space for maximum grip;

• laying the waterproofing layer is required. This is particularly important for the private house or villa in a swampy area;
• Penoplex before laying wooden beams and crossbeams treated with a special solution. This will avoid the appearance of rot and bugs.

Useful advice!If you live in an apartment building, then the choice Penoplex as insulation for floors - the best solution. This material is deposited a thin layer and does not affect the height of the room.

Thanks to its low weight, penoplex great for insulation in the floor frame house. The load on the structure of the foundation will be minimal. This will prevent shrinkage with time at home.

Highlights insulation haydite

Laying of the insulation occurs according technology unsubscribe above. However, there are a number of features that need to know. To carry out the floor insulation in a wooden house expanded clay, you must:

• necessarily lay a bed of sand. It is poured evenly and thoroughly tamped;
• on top of this pad is applied to the liquid layer of mastic. She plays the role of waterproofing;

• Now it is poured concrete block. To maximize layer was smooth and without voids recommended raznofraktsionny material. This will allow the beads fit tightly to each other;
• laying a vapor barrier is required. Only after the ground can be laid floor covering.

Due to the appreciable weight of the roofing, insulation wood floor expanded clay is best done with a solid foundation.

Warming of the wooden floor in the house with his own hands: video

Today, the Internet presents a great variety of self-training videos insulation installation. Their view will allow to understand the technology works and the principles of selection and milestones paving materials. In addition, these video scripts contain a large amount of useful things. So you can learn, for example, about the correct filling floor screed with polystyrene foam insulation.

To the floor of the house turned warm, it is necessary to take into account a lot of nuances. The right choice insulation plays an important role in this. When choosing the material for themselves, it is not necessary to start from fares or installation technology. Consider the type of structure, the nuances of the landscape and features of operation at home (permanent or seasonal). Based on this you can choose the perfect insulation for floors.
