Gender refers to the coldest part of the house.First of all, this is due to the fact that cold air falls down, and from under the floor blowing.Therefore, to reduce heat loss in the house and more fulfilled their underfloor insulation.This is particularly needed to make the premises with wooden floors.Even if the boards are stacked to each other tightly enough, after some time, they crack begins to show through the crevices of which leads to heat loss to 30%.

invited to consider options, what and how to insulate the floor of the wooden house from the bottom.

technology

insulate the floor in a private home is quite simple.For insulation you can use a variety of types of insulation.

Before you insulate the floor of the wooden house from below, should take into account the following parameters:

  • conditions in which the floor will be used (temperature and humidity inside the house, the purpose of the premises, provided the load);
  • required height of the layer of insulation.

insulate the floor with his hands is a snap.Insulation has three layers:

  • insulation;
  • vapor barrier;
  • flooring.

How to insulate the floor of the wooden house from the bottom: the sequence of work

  1. Stacked wooden logs.
  2. Grips bottom on the joists wooden boards or boards.This coating will serve as a support base on which is placed a heater.
  3. sandwiched between the joists insulation.Material should be installed tightly enough, and formed between joists and fill the gaps sheets special sealant or assembly foam.
  4. laid on the insulation and vapor control sheet.Vapor barrier fixed to the joists, glued metallic tape all joints and gaps.
  5. lay wooden flooring and made further finishing time.

thickness of the insulation layer is selected for each private house individually.It depends on the following factors:

  • what type of insulation;
  • any climatic conditions.

floor insulation on logs

Consider how warm the floor of the wooden house from the bottom of the joists.This method is fairly simple, but very effective, allowing to eliminate significant heat loss.

insulate the floor in a private house on logs as follows.

Initially, you need to install the wooden joists.Then fix the panels or boards, which will continue to be laid insulation.They hem bottom or secured on special bars.Further, between the joists put a heater on the deck, hydraulic and vapor barrier.At the final stage mounted floorboards and held finish flooring.

main advantage of thermal insulation of the floor joists - it is easy to work, which will be able to cope with virtually anything with the same efficiency at the highest level.

Materials for insulating floors

Today, construction market offers a lot of different thermal insulation materials, which differ in their characteristics, size, method of application and cost.

better insulate wooden floor?Thermal insulation can be achieved by using insulation materials that are used for thermal insulation of roofs and walls:

  • mineral wool (rock, slag, glass);
  • ecowool;
  • polyurethane foam;
  • polystyrene;
  • izolon;
  • penofol.

also used materials such as expanded clay, sawdust and styrofoam.Selection of an appropriate sealant depends on different parameters, preferences and capabilities of the owners of the property.

How to insulate old floor with sawdust?

Filings belong to one of the easiest types of insulation.Their main advantage is the relatively low cost (compared to other insulation materials), ease and simplicity of filling, which allows the warm and very difficult even bottlenecks.In addition, chips are eco-friendly materials.They can be used not only in pure form, but also to be included in different mixes.

mineral wool insulation of floors

insulated floor in an old house can be mineral wool, which belongs to one of the most common heaters.Its main advantage is the absolute incombustibility.It also has:

  • chemical and biological stability;
  • high insulation qualities.

Before warm wooden floor below the mineral wool should be familiar with its shortcomings.These include:

  • low mechanical strength;
  • low water vapor permeability;
  • ability to absorb moisture well, thus losing its insulating qualities (for this reason, when the installation of a vapor barrier must be addressed).

Furthermore, the material does not refer to a safe for the human body.

mineral wool produced in the form of hardboard or flexible mats.A more solid side panels represent a blue stripe.Laying should be performed so that the marking (the band) was at the top.Plates are usually used for the insulation of wooden floors.Stack them one layer.

floor insulation penofolom

Penofol refers to one of the new multi-layer roll of thermal insulation materials, which appeared in the construction market only recently and had not yet widespread.It consists of a heater and a special light-reflecting layer (thin polished aluminum foil).The basis (insulated material) can serve almost any insulation.The most in demand translucent material to which the polyethylene foam.

classic version penofol polyethylene foam is thermally bonded to the foil.But this option can not meet all the requirements of modern construction, so at the moment there are many varieties penofol.

Penofol classic has a high density, whereby it is able to withstand high mechanical loads.

Use material can perform both basic heat, steam and water proofing and insulation as auxiliary, in combination with another heater.

Due to the small thickness and presence of foil installation is simple, easy and fast.Insulation laid on the floor surface can butt or overlap.The resulting joints are sealed with metallic tape.Using penofol eliminates the need for installation of steam and water proofing.This function is performed by an aluminum foil.

floor insulation polystyrene (foam)

Styrofoam (polystyrene) also occupies a leading place among the heat-insulating materials.This is explained by the presence of a number of advantages and disadvantages from a minimum of material.Thermal insulation has a low thermal conductivity and water vapor permeability, high strength, fire resistance, biological, and chemical resistance.Due to the cellular structure of the insulation is durable and very effective as a thermal insulation.

disadvantage polystyrene - water absorption, due to which lost some of its properties.

floor insulation ecowool

Ecowool made from natural materials.75% consists of paper and 25% - natural special additives.This mixture of cellulose and binders therein are boric acid and antiseptic lignin.Due to this composition ecowool absolutely safe for humans, as well as being environmentally friendly.

Among its advantages are low thermal conductivity, fire safety (material does not burn, but only smoldering), having the ability to restore the insulating properties when wet.Disadvantages rank higher costs than other heaters.

How to insulate wooden floor ecowool?It is applied in various ways:

  1. Manual.The material is placed between the joists (bars) on the boards or panels, hemmed bottom.Ecowool should be laid tightly and place the docking process with foam.
  2. Mechanical.In this case, use mobile blasting machines, which are fed through the insulation of the hose under pressure.

Warming izolona

Izolon - a thermal insulation material made of expanded foam.The heater has been designed taking into account the current requirements for thermal insulation.Due to this, its use has a number of advantages.

First we note a small thickness of the material, which ranges from 2 to 10 mm.When this thermal conductivity is not increased.Izolon with a thickness of 1 cm of thermal conductivity equal to masonry.

Izolon by polyethylene foam does not get wet.Durable material not subject to decay, protects against steam and moisture.Insulation is environmentally safe, you can use it in any room.Such material may be used for both the main and auxiliary for insulation.Izolon the processing of wood flooring not only serves as insulation, but also plays the role of sound insulation, as is able to absorb the sound.Another advantage of this material is a little thick, which saves space.

floor insulation polyurethane foam

have foam cell structure, in which the pores are filled with insulating gas and air, which ensures a low thermal conductivity and at the same lightweight material.Therefore, the polyurethane foam is considered one of the best insulating materials.Its advantages include resistance to alkalis and acids, to rot, mold.

How to insulate wooden floor with polyurethane foam from the bottom?The material applied to the surface by spraying, using special equipment.This insulation is well engaged with different materials, so that it can be used for thermal insulation of all surfaces.This method allows to completely insulate the surface of different shape and complexity, repeating with precision all the contours and without forming joints.Due to its low coefficient of water absorption is no need for vapor barrier device.

floor insulation is an important step in preserving the heat and maintaining a favorable atmosphere in the house.

If you think, as a warm old wooden floor, and are going to make the purchase of material, it is necessary to consider all factors, prioritize, and only then make a final selection.
