High-quality thermal insulation of the floor in the house - the recommendations on materials and technology

Compared with the flat floor insulation options for private home is much greater.The main thing is to choose the correct technique not only of all the activities, but also the necessary materials.After all, this floor finish - is not only comfort, but also save money, since the consumption of energy, less intensively used space heaters and produced their share is significantly reduced.

As you know, just good planning provides the expected end result.We believe that the house is already in operation.

Things to Consider

• climate region, soil characteristics and location of the building on the ground.
• What floor will get off the ground.
• presence (or absence) of the basement.
• foundation type.
• type of materials used in the construction process;on what technology built building, equipped overlap.

It is understood that a single recommendation for insulation of floors, with view of the above, can not be.However, regardless of the specifics of the structure, there are activities that take place at all times.It makes no sense to dwell on various technologies - more than enough.Therefore, it is more expedient to understand what insulation and when it is better to use, as well as with the individual nuances of their installation.

But before we mention the types of jobs that are not always required, but recommended.A decision on the need for their conduct adopted on the basis of the characteristics of the floor, insulation material and the indoor climate.

Substrate preparation

Operation may be different.In principle, this stage in full - not all insulating materials.Much depends on whether, by what technique to arrange "finish" finish.If you are constantly cold and damp in the room, you also need to do everything from "scratch".

Cleaning the

How to make - is solved on the spot.We need to understand that the meaning not only in the garbage collection under the floor.The basis of the need to wash, scrape so that you could see in it the smallest shell crack.Visual inspection - the first case.What's the point wasting time and money on the insulation, if the surface has diverged interplate seams, chips, deep cracks?

Yes, and the presence of mold, mildew can not be ignored (as get rid of them, read here)."Spot", preventive maintenance is always cheaper capital.Of course - all defects subject to elimination.

impregnation

Any material, in principle, subject to destruction - all of it only in the intensity of the process.Therefore, the compositions are used to guard against fire (flame retardants - wood) from the mold and mildew (antiseptics), by absorption of liquids (waterproofing solutions, mastic).The cost of these assets is significantly less than those costs, which requires any repair bases.They sometimes substantially (time) "push" such an unpleasant event.

Priming

This surface treatment pursues multiple objectives:

• ensure reliable adhesive bond to the substrate (for example, expanded polystyrene insulation boards);
• «nail» the remnants of dust on the surface, otherwise the adhesive will be laid at a coating any lumps;
• strengthen the upper part of the base as the ground is partially absorbed in its structure;
• further reduce moisture permeability, since the composition of fills and seals the pores of the material.

Those who neglect this step, eventually a lot and lose.Now you can go to some of the nuances of warming.

house with a basement

To the floor was warmer, warming starts at the bottom.In fact, the basement - is a separate, recessed room, which has its walls, floor and ceiling.It is with them and should start.Finishing the ceiling cellar often eliminates the need to open the flooring in the rooms of the 1st floor, because it is usually enough of this "underground" insulation.

Recommendation

• The basement is necessary to ensure reliable ventilation - about it here.If there is insufficient natural, then mounted enforced.The lack of "traction" is largely due to the emergence of dampness in the rooms of the ground floor.
• Outside insulation of the foundation recommended if the internal was not enough effective, because it is more time-consuming and not always feasible.

Cellar no

work done on the ground or on a plate (if the foundation slab).In the first case it is filling with expanded clay gravel and settling screed quality.Next - surface preparation.It is necessary to worry about the device and secure water drainage system of the house (drainage).

Consider the main types of products, which are used for thermal insulation of floors.

Styrofoam

This type of foam has good strength, and if deformed, it is insignificant.And you need to choose an extruded material - it is more durable.But the installation of this product is only done on a flat surface - plate, plate, or the insulation layer will "play".

Keramzit

bulk material, so it can be installed anywhere - between joists, across the surface of the concrete.

Recommendation

If you want to maximize the sealing layer, you need to purchase products with different sizes of granules.In addition, such "filling" it is desirable to equip the layers, each of them carefully ramming and then "spill" cement mortar to reduce mobility.

Foamglass

Pre settling screed on the ground.On it are mounted units, are bonded to each other, and on top - another tie.In areas with excess moisture under it fits waterproofing.

granulated slag

It should be used with caution."Fresh" product with substandard treatment may contain toxins.It is generally used when laying directly on the ground (if no basement).Then - waterproofing and screed for finishing.

mineral wool

as budget way to warming.But we must note that it is only fit between joists as easily deformed.In addition, it absorbs moisture, so the quality of the waterproofing should be given increased attention.

Recommendation

plates (mats) can usefully obkladyvat waterproofing material on both sides.

OSB

This compressed mixture of wood chips and sawdust.Such an insulation not only reduces heat loss, but also aligns the substrate.In principle, the "finish" finishes, you can use linoleum, carpet, parquet board and other materials.

device - with the help of lag or rigid substrate (concrete).In the first case, you can pour a slab further expanded clay.This material is durable, combined with a certain plasticity.Manufacturing technology provides spetspropitku, so the material does not rot, and almost no moisture soaks.

There are other ways of insulating floors - gipsovolokno, double-deck, the system "warm floor", self-leveling compounds, linoleum and others.

Useful tips

• Different sources recommended for use as a waterproof coating roofing material.But for some reason few people pay attention to the fact that even under the most ideal conditions year after 4 it will have to change.Therefore it is better to stop the choice on the membrane or film p / e.
• Floor Warming will be incomplete if you do not pay attention to the plinth.It is in these places because of the loose fit them to the floor and walls of the "leaves" heat.Close up joints "tightly" it is impossible, as it is necessary to take into account the temperature deformation of the coating.But in addition to glue adhesive tape, for example, or "zapenit" in some cases, can not hurt.
• During walling always settling shut-off (horizontal) waterproofing.It is desirable that the corresponding layer in the room, not only it was located at the same level, but also securely docked.The task - to achieve a single "web", without gaps and bad joints.
