Warming of the floor: how to insulate the floor of the first floor effectively, reliably

comforts of home - it is, first of all, warm.We live on the ground floor, whether it is a private house, an apartment, a house over the arch or above unheated rooms, the floors often cause discomfort and other serious problems.It's cold, high humidity, annoying smell of damp all year round, especially in the dank offseason and consequently - endless colds whole family.Proper insulation of the floor during repair or at the stage of building a house will eliminate the above problems, and now adults, and even small children can mess around as much as necessary on the floor.


Complete solution three problems ↑

problems cold, moisture and odor of dampnessshould be dealt with in the complex.For warming the floor the first floor has fulfilled its primary function, it is necessary to carefully seal the holes, cracks and joints in the concrete slab, and in places of its junction with the wa

lls.For this purpose, the foam core may be used.

Polyurethane foam - a great insulator, and expands, it perfectly fills any tiny bumps and seals even through the slit.In addition, it is easy and does not create an additional burden on the overlap.Treatment with foam along the perimeter of all joints and gaps will get rid of the smell of damp and mold from the basement.Excess dried foam should be cut with a sharp knife.

To get rid of moisture in the flat on the concrete base floor must be put a layer of moisture-vapor barrier.This can be a roofing material, asphalt, polyethylene film, or any other modern paroizoliruyuschy film material.Panels insulating material lay across the floor area overlap by 15-20 cm. Designated laps glued bitumen sealant and fasten staple gun, and give birth to the film web on the walls to a height of 18-20 cm.

Warming of the floor - a comprehensive solution three problems
Before insulation on the concrete subfloor must be laida layer of moisture-vapor barrier.

next stage - warming the concrete floor of the first floor is performed by one of the following options:

  • Classic floors on joists;
  • Ties opilkobetona - arbolit;
  • National floors dry.

Classic beam floor ↑

Logs of wood are placed on the floor in the vapor barrier with a pitch of 500-600 mm is generally parallel to the shortest side of the room.By the concrete base of the floor are fixed with special anchors 8-10 x 200-250 mm.In the space between the joists insulation layers are laid, usually wool, at least - of the foam.

for cold and wet conditions of the first floor better than any other insulation is suitable mineral basalt wool: it does not burn and practically non-hygroscopic.

Fiberglass is recommended for warming only if done very carefully steam waterproofing.This material is very hygroscopic.

foam as insulation of the floor of the first floor is almost never used because of the non-compliance with fire safety, besides it can izgryzt rodents.

Styrofoam - the most expensive insulation, but its use is justified if necessary to ensure the thickness of the insulation layer is less than 50 mm.

Classic floors on joists
floors on joists - traditional design for thermal insulation of the floor of the first floor

After laying insulation on the joists plank rough floor of pine decking planks and finally - any surface finish: parquet, laminate, tile, linoleum or carpet.By clicking on the floor joists, it should be noted that a thickness of about 7-10 cm and in rooms with low ceilings, too, he is not always acceptable.

flooring arbolita ↑

Arbolit or opilkobeton - very popular in the recent past, but undeservedly forgotten cheap, lightweight and durable material for thermal insulation of the floor.It is also called drevobeton and orgabeton.The mixture is made from sand, cement and wood chips, for adding mineralization chemical additives or calcium nitrate, water glass.The benefits are undeniable arbolita:

  • High thermal insulation;
  • small share;
  • High strength;
  • Sustainability;
  • Off;
  • high flexural strength;
  • high degree of sound insulation;
  • Ease of processing;
  • very low cost.

But there is this material two significant drawbacks:

  • layer thickness of 100-150 mm;
  • long time completely dry without chemical additives - 22-25 days.

Given the substantial thickness opilkobetona, insulate the floors of this material is possible only in rooms with relatively high ceilings.Pour a mixture of the two layers.

For the first, thicker layer, a mixture of one part of the calculation of M400 cement, two parts sand srednekrupnogo, six pieces of wood sawdust and pour an even layer thickness of 70-80 mm.

For the second level, acting as a final covering, mix one part cement M400, two parts sand, three parts sawdust and pour a thin layer of 20-25 mm.

Arbolit - cheap, lightweight, durable mix for floor insulation on the ground floor

After complete solidification after 3-3.5 weeks arbolit can be laid parquet, laminate or any other floor covering.

National floors dry ↑

This kind of gender-based dry leveling compounds and gypsum fiber boards called dry screed, it is easy to install, is performed without the use of water due to the coating thickness not exceeding 50 mm, suitable for rooms with low ceilings.

Prefabricated dry floors
Dry screed - a modern and effective way of warming the concrete floor

on a layer of vapor-proofing poured a layer of fine quartz sand or expanded clay, lining backfill using a long level and, if necessary, lightly tamping.

expanded clay backfill placed on top of two layers of moisture resistant gypsum fiber sheets, stapling them together with dowels.You can also use sheets of water-resistant plywood, used in the construction of yachts - is a very durable and wear-resistant material, which is practically not deformed.If you use the panel "superfield KNAUF», enough of one layer: they initially have a double thickness.Sheets of the coating material, it is desirable to glue together, and tight joints putty putty for exterior for strength and water resistance guaranteed.

  • modern German technology of dry precast floor is rapidly gaining popularity due to many advantages:
  • Excellent insulation;
  • Moisture;
  • Soundproofing;
  • simplicity and speed of installation, requiring no special training;
  • Cleanliness work;
  • Suitable for installation not only in the concrete, but also on the wooden floor;
  • small share.

dry precast floor can be walked on immediately after laying and to lay finishing flooring - parquet, laminate, linoleum or floor tiles.

enumerating the traditional methods of warming of floor structures of the first floor, it should be noted and the most modern and most efficient systems - water and electric and infrared heated floors.Radiant floors are not recommended for use in high-rise buildings because of possible leaks, but ground floor apartment this prohibition does not apply.Electric underfloor heating is easy to install, but at considerable cost to their operation.No matter which way you choose a floor insulation, the most important thing that your abode on the first floor will be filled with warmth and comfort.
