How to insulate the floor with glass bottles How to insulate the floor with glass bottles

In this article we will talk about whether it is possible to insulate a bath with the maximum possible efficiency, but at the same time not to use expensive and dangerous material for the human body? The floor in the bathhouse made of bottles will fully meet the requirements that can be imposed even on modern heat-insulating materials. Of course, there are no regulations governing the use of empty containers during the construction process. The use of glass bottles for floor insulation was guessed by home craftsmen, who rightly believed that the bottles would have similar characteristics to glass blocks.

Indeed, the floor in the bath made of glass bottles will fully meet all the requirements that can be imposed even on modern materials for thermal insulation.

General information

How appropriate is it to use bottles for floor insulation

How to insulate the floor with glass bottles The room, or rather the floor in it, can be insulated using both glass and plastic containers.

Empty bottles, which will be tightly packed with the floor covering, will provide an air gap between the base and the base. The heat-conducting properties of air are ten times worse than those of solids, so the effectiveness of this type of insulation will not be in doubt.

Of course, the question may arise as to how to accumulate such a large amount of containers. In fact, there should be no difficulty in performing such a task. It is not at all necessary to resort to the method of accumulating building material on your own, since the bottles you need are in large quantities in the waste containers.

If this option is not suitable for you, then you can make a large supply of bottles in a relatively short period with the help of family members, friends, relatives and neighbors. There is no need to speed up the process by buying drinks a little more often or in large quantities, since all the charm of the method, which is cheapness, will be lost. It remains only to allocate space for storing plastic or glass containers.

Empty bottles, which are placed under the floor covering, are able to provide an air gap between the base and the floor.

Reviews of know-how owners

From the owners of the floor in the bath, which is made of bottles, you can hear the following:

  • " The neighbors, when they found out that I had made a base from glass empty bottles, at first laughed at me, and now they themselves are building the same floors" (Igor A.


  • "In my dressing room, under the cover, there are plastic containers with a volume of 1.5 liters. The result is a wonderful warm floor, which cost me a penny" (Alexander T.)
  • "It makes me so funny when someone says that the base is made of glass bottles.They create cavities under a strong reinforced concrete screed "(Yuri P.


  • " It is difficult to call such a structure a full-fledged warm floor, since the bottles are not able to generate heat, but agree other thermal insulators cannot do this either. Their task will be to minimize heat loss. With empty and unnecessary containers, it works out very well "(Mikhail N.)
  • " And what? I have a lot of bottles, why spend money on any other materials? To begin with, I thought about insulating the floors with such material only in the bath. It so happened that there was a break in construction, but I did not regularly throw out the container, but kept it inside the basement.

    It was enough to finally make the thermal insulation of the concrete ceiling "(Alexey I).

We hope that after these reviews you have dispelled doubts about the advisability of using empty containers as a material for insulation. The process of insulation will not be difficult.

Thermal insulation with glass bottles


How to insulate the floor with glass bottles Immediately it should be noted that when preparing containers for insulation, care should be taken in advance to ensure that it is sealed. Corks from PET containers are rarely lost, but the same cannot be said about glassware.

But in fact, the problem with sealing the container can be solved with the help of various improvised means.

And if you do not close it? The air in the container, which is not tightly closed, will contact the external environment , and then will receive a higher heat conductivity, which can worsen the thermal insulation characteristics of the floor. Therefore, when warming the floor with bottles e the tie should be checked everything for the cover, which will be tightened tightly.

Please note, that it is better to do the floor from bottles with your own hands when it's sunny outside. Experts recommend warming up the container before sealing and installing it.

When the air in a sealed container becomes cold, it will be more rarefied. Everyone knows that the coefficient of thermal conductivity of a material decreases at the same time when its density decreases. The floors in the bath, made from bottles with your own hands, are best done in sunny weather, since the containers will warm up themselves, moreover, quickly and strongly enough.

Thermal insulation of the finished floor covering

How to insulate the floor in the bath with glass bottles, if the building has already been erected? It should be borne in mind that the height of the room will be significantly reduced, therefore, this method will need to be abandoned if you have low ceilings. If you nevertheless decide to implement this idea in your own bath, then for a start the container should be placed only horizontally.

It is laid so that gaps remain with the bottles, but they are minimal.

Before making thermal insulation for the floor from empty containers, a layer of roofing material should be laid on the sub floor.Adjacent waterproofing sheets must overlap. Roofing material should be laid with an overlap on the walls, which will correspond to the thickness of the future floor. All edges of the insulating material should be sealed with bitumen mastic or adhesive tape.

Please note that a water drainage system should be taken care of in the bathing area before placing bottles.

The gaps between the containers, which are laid out on the base, should be filled with dry sand. Next, you should lay an additional layer of material for waterproofing, and then lay a reinforcing grid. It should be positioned 1.2-2 cm above the membrane, so that after pouring, the reinforcement is immersed in concrete.

Please note that the thickness of the screed should not be less than 3 cm. After the mortar has hardened, you can begin to finish the floor.

Thermal insulation of the floor surface at the stage of building a bath

During the construction of a bath, a heated floor from bottles can be made directly on the ground. First you need to remove its upper loose layer (from 20 to 25 cm). The bottom of the small pit should be leveled and tamped.

Pour a layer of sand, ASG, screenings or crushed stone onto it. The drainage layer should also be well tamped. Next, you can lay everything with a reinforcing mesh on it, lay the bottles on it as described above (with minimal gaps and horizontally). An additional layer of reinforcement should be laid over the dishes. Next, the bottles should be poured using a concrete screed with a thickness of 6 cm.

When it hardens, you need to lay a layer of waterproofing and fill the floor with a finishing screed.

How to insulate the floor with glass bottles Useful advice! In order to keep the floor of bottles warm in the bathhouse better, they can be laid in 2 layers.

After laying the first layer, you can make a reinforced screed. A second layer of empty bottles is placed on it. It is poured with concrete, and then they continue to finish the flooring.

If the soil is not dense enough, then thermal insulation should be arranged on a base that is poured with concrete. To insulate the floor with glass bottles, a rough screed should be made on the ground immediately after tamping of a crushed stone or sand bed and laying a membrane for a waterproofing type on it. A rough screed can be made from lean concrete.

Thermal insulation from bottles will be much stronger when placed vertically. The container should be placed with the necks down.

This method of insulation will require more bottles, but the thickness of the air gap between the floor and the base will be much smaller. It is difficult to hold the crockery upside down on a concrete slab. It is better to install it like this - stick it with its necks into the rammed earth. Such a thermal insulator will be stronger than horizontal rows.

Before making the floor of the bath from empty bottles, it is imperative to make a furrow in the ground near one of the foundation walls.

Insert the container necks into it. On the bottoms of the bottles, for their good fixation, you can slightly tap everything with a rubber mallet. After installing the first row of bottles, the furrow should be filled up, do the following, put the second row of containers and so on until the end. The thermal insulator from vertical bottles will be stronger than from horizontal rows, so the screed above it should be poured with a thinner layer, but reinforcement should be done in any case.

Warming with plastic bottles

And how to make a warm floor in a bath from plastic bottles? For some reason, most people mistakenly believe that such a container is not strong enough to withstand the mass of concrete.

Surely everyone knows that closed plastic dishes wrinkle when cooled. Anyway, PET bottles are used for floor insulation with the same success as glass containers.

One way to prevent deformation of containers is to fill them with sand, sawdust, dry clay or other similar materials. Naturally, it will be useful to remember that closed plastic dishes must be warmed up as best as possible before pouring concrete. When cooled down, it will decrease in volume, but this will not affect the strength of the reinforced screed.

At the same time, a layer of air will remain under it, which does not conduct heat well. PET bottles can be installed in an upright position (in the same way as glass). In this case, the thermal insulation layer becomes much stronger. Just do not forget that you need to warm up the plastic dishes well.

The following factors will contribute to the quality performance of the work:

  1. Before insulating the floor of the bath with bottles, the temperature in the room should be adjusted from +20 to +25 degrees.

    If the overlap is to be done outdoors, then only a sunny day should be chosen for laying the thermal insulator and pouring it with concrete mortar.

  2. Mix the solution in heated water - warm concrete will not allow the air to cool in a plastic container. Excessive pressure will help to strengthen the walls of the pot until the solution begins to solidify.
  3. The screed must be reinforced. The maximum mesh size of the lattice for reinforcement should not be more than 15 * 15 cm.


What other materials are possible use for insulation, in addition to bottles (glass and PET)? For such a procedure, you can also use glass jars, if, of course, everything can be set according to the thickness of the overlap. True, it will be more difficult to save them, and it is not so easy to equip such a container with a sufficient number of lids. There is an option to take dishes with screw-type necks. Cans can be stacked upside-down with bottles, providing a relatively level base for the screed.It is not contraindicated to make thermal insulation from dishes with different volumes, as well as containers that are made from heterogeneous raw materials.

The main thing is that she fulfills her task - to keep warm in the bath.
