How and how to insulate the ceiling in a house with a cold roof

Nowadays, heat is very expensive, and prices for different types of heating increase. Therefore, many people think about how best to maintain heat in a house or apartment. Nobody wants to warm the street, and the insulation of the house with a wide variety of methods is gaining more and more popularity. Distributed ways to save such valuable heat are insulation of walls and windows. However, in this article we will talk about how to insulate the ceiling. Few people know that due to the characteristic ability of hot air, most heat, namely 60%, is lost through the ceiling overlap. Moreover, when the heated air reaches the cold surface of the unscrupted ceiling, it turns into condensate, simply put to moisture. Therefore, thanks to insulation of the ceiling, dampness in the upper corners of the house can be avoided, and hence the appearance of mold and fungus there. So, today we will find out how to insulate the ceiling correctly and how to do it.

What to take into account when warming the ceiling with your own hands

There are several basic rules that we must not forget about, deciding how to insulate the ceiling. Although the features of construction and repair in the house, financial capabilities and other criteria make this choice individual, yet these few tips will be useful to anyone who wants to maintain heat in their house. So what needs to be taken into account:

the insulation material should be environmentally friendly, and, of course, not toxic;
the insulation should be fireproof - do not contain easily igniting substances, as well as substances that, when burning, secrete poisonous gases;
the material for insulation should be reliably protected from moisture from entering it to avoid damage to it and your ceiling;
when the ceiling is insulated from the inside, it is also important that the material is as thin and light as possible.

How to warm the ceiling with your own hands

Now consider materials for thermal insulation. To make a decision, the better to insulate the ceiling, it is necessary to consider in detail the possible options.

Not so long ago, clay, straw and sawdust were the only affection for people, at our time, technologies are so large that it becomes not so simple to choose. The table below indicates the main materials for insulation, as well as their advantages and disadvantages.

Material	pros	Minuses
Mineral wool	Vapor permeable; Environmentally friendly	It is necessary to use in conjunction with additional waterproofing, moreover, very careful, which makes the process of insulation more expensive; It cannot be covered, rammed or removed; a very thorough styling is needed, because the slightest gap can skip cold; Minvat needs to replace every ten to fifteen years.
Ecowata	Absolutely harmless to humans; elastic and elastic, due to which it does not give shrinkage; vapor permeable; prevents the appearance of the fungus; has soundproofing power; Fireproof.	When laying, a cloud of dust from boric acid occurs; installation should only be performed by professionals with special equipment; Ecowata is not recommended to be used near the fire or high temperatures (for example, in the bath), since the process of smoldering will begin.
Styrofoam	Has a very low thermal conductivity; Resistant to damage by microorganisms.	Fire hazard; Some substances in the composition are short -lived; rodents can start in it; It comes from it toxic gas with a pungent odor, which harms health and is also explosive - formaldehyde; Foam practically does not breathe - the premises need ventilation.
Ceramzit	Cheap; durable; Good sound insulation.	Absorbs moisture; We need a lining, since there are a lot of crumbs and dust from expanded clay.
Penoizole	Inexpensive; insulates hard -to -reach places; fireproof; Breathing well; not destroyed by microorganisms and rodents; has a high temperature range at which it retains its properties; Good sound insulation.	Low mechanical strength, which requires additional finishes to protect the material; the complexity of independent insulation work; Penoizole exudes harmful substances.
Sawdust	Inexpensive.	Outdated method, although it is sometimes used; Sawdles are fire hazard; they cure, so you need to add fresh; For such a heater you can not walk, so it is suitable only for rooms that are not used.
Clay	Environmentally friendly; cheap; does not burn.	Under clay, wood is prone to decay and the appearance of fungus; If clay and sawdust are incorrectly mixed, the opposite effect can be observed from insulation - more heat will go more.
Foil insulation	It is convenient to mount, as it is made ready, even happens with glue; good in rooms with concrete ceilings; It is often used to insulate the ceiling in the bath.	If it is not tight enough, leaving the cracks, then the tree under the foil will deteriorate.

How to warm the ceiling with your own hands

There are several ways to insulate the ceiling in a private house:

1. Ceiling insulation from the inside.

This method is applicable when the attic is in your house in your house. It can also be used in the apartment when another apartment is above you or for any reason there is no access to the attic.

In order to insulate the ceiling from the side of the room, you need to build a wooden base - the frame - and attach it to the ceiling. Next, you fill out the basis of your chosen type of thermal insulation, add a vapor barrier that should be between the insulation and the ceiling, and lift it all with drywall with below. Of course, with this method, the height of the ceiling is significantly reduced. In addition, it is quite laborious.

2. Ceiling insulation from the attic side.

If the attic is under your roof, then it will be much easier to insulate. Taking into account whether it is operated or not, you can choose one of the right materials for insulation.

Warm the ceiling with owl with our own hands

Before starting work on the installation of insulation materials, it is necessary to remove everything that lies from the attic, the replacement of the floor and even wash it. Depending on the size of the surface that must be insulated, it is necessary to prepare the foam in the appropriate amount. It should be at least 40 mm thick with thickness. You can also buy penostrol, but it will come out much more. Both polystyrene and foamyle have a high level of thermal insulation abilities and greater resistance to damage to microorganisms.

The entire area of \u200b\u200bthe floor should be covered with sheets of foam, the joints must be glued with mounting foam. On top of the foam we lay the reinforcing mesh and pour the concrete screed in case you plan to use the attic. The layer of the screed should be at least 5 cm.

Penoizol gives a much better result when warming than ready -made stoves from foam. This is because the polystyrene can do not fit the main frame, as a result of which the cracks may appear that will let the cold pass. The use of foamyizol also helps to reduce transport costs and an expenses of electricity. Since there are resins in the penosole, it adjacent to the surface well and fills the cracks and voids. It takes about twenty minutes to dry. However, Penoizol has one minus: it cannot be filled yourself, professionals should do this.

Foam plates can be attached to the frame, or you can simply glue it to the ceiling. If you decide to use the adhesive method, then consider the following features. While working with glue, the temperature in the room should be in the range from fifty degrees below zero to two hundred and fifty degrees above zero, so that it grabs well. For installation, you can use glue for tiles, and after its drying it, you can continue finishing work. To attach the stove from the foam, you need to apply tile glue to both surfaces, wait a few minutes and press the stove to the ceiling. After all sheets are glued, you need to carefully close all the cracks and places of joints with glue or mounting foam.

If desired, when the design hardens, you can reinforce the ceiling. To do this, it is necessary to apply a special solution to the foam, then glue a fiberglass grid on it. On top of the grid you need to apply a second layer of solution, wait until it hardens and you can do further work.

If you have chosen a frame method, then you need to attach the slats (metal or wooden) to the pre -prepared surface of the ceiling so that it looks like a grate. The size of the grooves should be a quarter of a sheet of foam, and so it will be necessary to cut the sheets. In the formed cells, it is necessary to insert the plate on which glue is applied around the perimeter. Further, as in the previous case, the ceiling can be reinforced and finished to your liking.

We warm the ceiling with mineral wool with our own hands

When working with mineral wool, it is very important to follow the safety rules: it is necessary to use protective clothing, as well as protect the eyes and respiratory tract with protective glasses and respirator, since the substances that make up the mineral wool aggressively affect the skin and mucous membranes. However, such precautions are necessary only in the process of installing mineral wool: after the end of all the necessary work with it, it ceases to be dangerous.

Before strengthening the ceiling with mineral wool, you also need to prepare the surface: remove garbage and dirt so that pure concrete remains. Next, you need to make a wooden structure-rest. Under the bottom you need to put a layer of vapor barrier. Then we lay mineral wool on top, the main thing is not to trample it, put it freely, otherwise it will lose its thermal insulation properties. For the best result, you can make two layers of cotton wool by laying them over. After the laying of mineral wool is completed, the floor is made, which is attached to the frame. If you need to insulate a wooden ceiling with mineral wool, then the frame must be made of wooden rails. Mineral wool must be opened strictly before laying.

We insulate the stream of ecovite with our own hands

As already mentioned, professionals should be stacked by Ecowatus. It is manually to do this hard and time -consuming, in addition, if an untrained person is engaged in the installation, then the result of insulation falls by twenty to thirty percent. Ekovata can be laid in two ways: moist and dry. For dry laying, special equipment is used, which, using air pressure, fills the ecowine frame, and not only horizontal, but even vertical. The humid method is based on one feature of the ecovy: when it gets wet, the substances that make up it make it adhesive. Using the same equipment, Ecowata is sprayed to the surface, to which it is glued, turning after hardening into a dense and even layer, which, in addition to thermal insulation, also does not miss the sound. In some cases, cotton wool is wetted not with water, but with liquid glue, so that it is even better grasped with the surface.

Warm the ceiling with expanded clay with our own hands

Expanded clay is placed like sawdust or clay. At first, as always, we prepare the surface, cleansing it of all superfluous. Then we make a wooden frame, as in previous cases. Under it, it is necessary to lay the waterproofer so that the sheets lay overlapping, connect the joints with tape and cover it with a reinforcing mesh. After that, fall asleep expanded clay. By laying a sufficient layer of insulation, we attach vapor barrier on top to wooden base. Next, you need to perform a cement screed. On top of the cement screed, you can already put any floor covering.

There are other methods to insulate the ceiling in the house with a cold roof. To make the optimal decision, consider the features of your home or apartment, your material capabilities, as well as consult with specialists. They will help to correctly calculate the durability and effectiveness of different materials, and your house will be warm.
