Warming of the floor of the first floor

a significant amount of heat can escape through the floor of the first floor of the building.To minimize heat loss, and with it, and reduce the cost of heating homes, you need to perform a qualitative and proper insulation surface.

There are several ways to implement this problem.At the same time to create a reliable heat-insulating layer can use different heaters.Check out the features of the most popular materials, select the most appropriate method and proceed to installation of insulation.

Popular insulation materials and their characteristics

On today's construction market a large variety of materials, the characteristics and properties that make them suitable for thermal insulation of the floor of the first floor.Each bushing has a number of advantages and a certain list of weak qualities.

Mineral wool

Tech.characteristics of mineral wool	Indicators
	density of 115 kg / m3
Water absorption at full immersion, no more	1%
average fiber diameter of not more than	0,2 m
Content fibrous inclusions in the mass, not more	4,5%
Thermal conductivity at 283 K + 1, max	0,044 W / m * K
shear strength, not less than	50 kPa
compressive strength, not less	100 kPa
tensile strength, not less	150 kPa

most popular material for thermal insulation of various constructions is rock wool.Among its main advantages can be distinguished:

• high thermal insulation properties;
• to the fire resistance;
• good sound insulation;
• relatively low cost.

  Comparative characteristics

main disadvantage - poor resistance to moisture, against which there is a need for high-quality waterproofing layer arrangement, otherwise the heater very quickly destroyed.

Mineral wool is made in the form of slabs and mats, which makes it possible to choose the most convenient option for your situation.

foam

Equally popular insulation material.Advantages:

• low thermal conductivity;
• small thickness and relatively low weight;
• strength;
• durability;
• resistance to mechanical damage.

Unlike mineral wool, foam does not require the device so severe moisture protection.

If you have enough budget, you can and do buy polyethylene foam.During the production of this material, its surface is covered with aluminum foil, eliminating the need for arrangement of additional waterproofing.

Ecowool

Represents insulation based on cellulose with a variety of additives that contribute to the improvement of its fire-resistant and environmentally friendly characteristics.The structure is a bulk material.Ecowool very simple in arrangement - just pour it into a pre-assembled crate and shelter deck.

ecowool major shortcoming is its low resistance to moisture.Under its influence the material quickly loses its operational properties and destroyed.

Fiberglass

This heater is rapidly gaining popularity.The basic operational characteristics of the glass is praise.The material is excellent for thermal insulation of floors of premises, located on the first floor.Also among the advantages of fiber should include an affordable price.

Choice arrangement method of thermal insulation layer

Before carrying out thermal insulation measures, it is necessary to examine not only the most popular properties of insulation, but also to get acquainted with the peculiarities of their arrangement.Depending on the structure of the materials are classified:

• bulk;
• solid.In this category are rolled insulation, and insulation materials in the form of mats and slabs;
• liquid.

Loose insulation

performed using the above-mentioned ecowool, as well as the following materials:

• slag;
• crushed foam;
• sawdust.

Granular materials are convenient in that they can be insulated even the most remote places.The method is equally effective in private homes or in apartments on the first floor.

However, despite its efficacy, loose insulation is not widespread because the market are available in more modern and simple in arrangement of heaters.

solid insulation

coils, slabs and mats are most commonly used for insulation.Such materials have a relatively small thickness - an average of 100 mm, so the living space using them decreases insignificantly.

Typical representatives category - mineral wool and polystyrene.It is also gaining wide popularity mats made from plant fibers of natural origin.

Liquid insulation

not very common, but very effective method.The following materials:

• mortar with addition of sawdust, expanded clay and other excipients;
• sprayed polymer-based formulations.
  

  Warming Liquid insulation

The quality of such insulation in no way inferior to the plates, mats and roll materials.However, spraying formulations have to use special equipment, which is not the best way affects the cost of the work.

Options floor insulation and instructions for their implementation

procedure for warming the floor the first floor will vary depending on whether the bottom of the cellar or basement present.

If there is a basement

the presence in the house basement or a basement heat insulation work should start with them.Firstly, you have to insulate the walls and ceiling of the basement.Secondly, before the insulation surface quality should be waterproofed.Otherwise, the ground water seep through walls and destroy the insulation.

If you do not want or intend to disassemble the floor to create the most high-quality insulation, use the method, the essence of which boils down to the basement ceiling insulation.

first step. Lay and secure the waterproof film.Lay the strips of film with 10-15 cm of overlap.Joints certainly cement the tape.

second step. pinned to seal the surface of the batten.The width of the strips and their placement step is selected according to the parameters used insulation.

third step. Place the slab or roll insulation in the space between the rails.For fixing thermal insulation, use wire or tamp the cross rails.

fourth step. rails nailed to planks (boards or OSB).

After isolation of the basement, you can go directly to the floor insulation.

first step. Place the logs and attach them to the cranial bars.

on fixed bars lay wooden boards or OSB.Flooring should be such that at the junctions of the elements was not even small cracks.

second step. Nestle flooring Waterproofing foil.

third step .Place the film on top of the selected heater.Fasten the base of the support logs.

fourth step. Take another flooring or OSB boards.The gap between the flooring and insulation should be about 10 mm.

If there is no basement

If no basement or plinth work on the floor insulation will pass more easily and quickly.If not mentioned space, the floor, usually located directly on the ground or on the same foundation.

In this situation, the sequence of warming will be as follows.

first step. Remove the flooring if any, to gain access to the basement or the ground.If the floor is placed on the ground, carefully align the ground.

second step. Pour on the basis of expanded clay 10-15 cm layer.This filling will provide additional insulation.

third step. Puts reinforcing layer.The required stiffness provide common-mesh netting.Lay it on the ground.

fourth step. Make a new tie.

fifth step. Nestle frozen screed Waterproofing film.

sixth step. nailed to the bottom batten.

seventh step. Place selected insulation material in the space between the rails.

eighth step. Assemble the floorboard and perform finishing at its discretion.

insulation option with a floor heating system

This technique is not warming in the truest sense of the word, but allows you to make the room much warmer.The system may be electrical (film, cable) and water.

The simplest arrangement is a film in the infrared heated floor.To install it, just enough to align the base to spread the film in the appropriate places and connect the system to the electricity.Screed not filled.The key advantages of this system is the possibility of placing it under any surface finish and ease of installation.Disadvantage - relatively high cost.

Cable floor also relatively easy to packing and can be combined with most types of existing flooring finishing.You do not need to tie.The main drawback - the high cost of operation.

The most popular is the radiant floor heating.This system is the most economical.It requires prior arrangement foundation waterproofing, laying special mats (best to use a plate with a so-called bosses, as in this case do not have to use additional fasteners) and the subsequent screed.

Thus, for thermal insulation of the floor of the first floor, you can use a variety of materials and techniques.Now you are aware of the peculiarities of each of the available options and will be able to make the best choice.

Insulating material	Thermal conductivity (W / m × K °)
Mineral wool	0,045-0,08
Ecowool (cellulose insulation)	0,038-0,046
Fiberglass	0,033-0,06
styrofoam (polystyrene)	0,031-0,040
Keramzit	0.16
Claydite	0.31
Foil polyethylene foam (penofleks)	0,032-0,037

Successful work!
