How to insulate the ceiling in a private house from the inside?

In winter, the thermal loss of the ceiling structure is about 15%. Since the house is warm and it is cold outside, condensation forms in the room, a favorable atmosphere is created for the reproduction of bacteria and fungi. Therefore, you need to think about the effective insulation of the ceiling in the inner part of the house.

The main feature of the ceiling insulation from the inside is the impossibility of organizing condenser drain. The situation could be corrected by drainage walls. However, their cost is not everyone can afford. Depending on the season, the ceiling can quickly heat up and cool down. For this reason, the main technology of ceiling insulation is oriented so that condensate is not created in the finished structure.

In the people such heater is called glass wool. If this material is used in conjunction with a suspended ceiling, drywall will create an insurmountable barrier to the outgoing heat.

The installation of mineral wool should be divided into several stages:

• Collection and installation of the frame on a metal or wooden base. For this process it is worth using an electric drill and dowels.
• Filling the void between the parts with mineral wool. As an attachment used special glue for tiles. It instantly hardens and creates a reliable fastening of the material. Do not forget about the additional installation of vapor barrier.
• At the final stage of work on the ceiling install drywall. It is recommended to use self-tapping screws made of hardened steel as fasteners (they have high strength and are able to withstand maximum loads).

To an ordinary person it will seem that the installation technology is quite simple. However, any installation process has its own nuances.It is strictly forbidden to press mineral wool. The main effect of heat preservation is that the bubbles located in the inner part of the material do not provide heat exchange between the ceiling and the attic.

Spotlights can also create a problem. Energy-saving lamps are known to become very hot. Mounted insulation will prevent the removal of heat from the lamps, which will lead to their rapid breakdown. An alternative option is to create an additional gap between the luminaires and insulation, (preventing the heat sink and air circulation).

Various shops and markets of building materials offer a large selection of insulation. Against this background, there are several varieties.

Mineral wool - the usual textile fiber obtained by various methods. A fiber made from volcanic materials is called stone rock. Slag is based on blast furnace slag. Glass wool is a raw material created on the basis of molten glass. As for the thickness of the insulation, the index ranges from 2 to 20 cm.

Polyethylene foam in the form of a roll on the foil basis - a heater of a new generation. The thickness of this material is from 3 to 20 mm. Polyethylene is the most effective material used for ceiling insulation. The small thickness makes it easy to install in a private house and apartment.

Polyfoam - the material made of plastic mass in the form of cells. Available in the form of squares with a size of 1 x 1 m. The thickness of the sheet is from 2 to 10 cm. The density of the material varies between 15-25 kg / m2 (foam insulation 25 kg / m2 is more often used for insulation of the ceiling). Polyfoam is often used for insulation of hanging frames, walls and other coatings of a private house. He has good reviews.

Extrusive polystyrene foam is formed by making special polymers: the finished insulation is created by extruding the material through a special form 120x60 cm in size. The thickness of the finished sheet ranges from 10 to 200 mm.For insulation of ceiling structures often use a material with a density of 25-45 kg / cm2. In simple terms, it is foam made using a different technology. Its main difference is the higher strength of the material.

You can warm the ceiling with loose clay. This material is more often used for warming attic floors. In addition to basic materials, weatherization can be accomplished with an isolon, penofol, penoplex. It is important to fix the insulation material correctly. The materials are suitable for insulation on the top floor, veranda, basement, attic.

Stopping on the choice of insulation, special attention should be paid to flammability, strength, weight and permeability. The cost of insulation plays not so important a role as its effectiveness. There are wooden and concrete floors. Concrete structures, unlike wooden ceilings, have a large bearing capacity. Concrete is considered to be a partially vapor-permeable material, but finished slabs lose this indicator.

Wooden ceilings are more common in private homes. Usually attic floors are installed on a wooden base. It is known that the tree is subject to burning and well passes any couples. If you try to close the access to the air, over time, the tree will start to rot. It is necessary to highlight the key factor influencing the choice of material - the location of the insulation layer. The ceiling can be insulated from the attic side of the house and its inner part. Lovers of low-cost, simple and affordable options for insulation suit the attic floor.

Experienced experts do not recommend insulating ceilings in the inner part of the room. The main reason is the danger of penetration of insulation or its fumes into the room. Consider the best options for placement and installation of ceiling insulation, observing the technology of work and precautions.

As an effective option you can use polystyrene foam (EPS). Installation work begins with the installation of crates. In the next stage of work, polystyrene foam is installed. The thickness of the insulation should be 3 mm.

Next, measure the space between the slats (no more than 2 mm).Empty space is filled with insulation and fixed with dowels. At the end of the crate fix the drywall as a suspended ceiling. Alternatively, tension structures can be installed.

Polyethylene foam is not as effective as a heater. It can be used for insulation in the event that heat loss is small. Mount the crate on the ceiling and fix the penofol with dowels. After mounting on both sides of the material, a small gap is made for ventilation of the air and one more crate is installed.

Plaster mixtures may become an additional heater. They are an excellent insulation for the ceiling on a concrete base. Plaster mixes have high environmental friendliness. They do not burn and fit perfectly into the architectural style of the house. One of the most natural and high-quality materials for thermal insulation inside the hands is the agglomerate of cork bark. Such material is mounted on the crate.Since bark plugs are not afraid of moisture, vapor barrier is optional.

Warming of the ceiling in the inner part of the room depends on the material used. Using foam, you can not install the crate, because it is perfectly mounted on mastic or glue. Additional strength to other materials forms a hinged design. In wet rooms (for example, a bathroom), an additional metal profile is used, in other situations a wooden structure is used. However, to insulate the ceiling without decorative decoration will not succeed.

The profile must be fixed under the dimensions of the insulation. As a waterproofing material used film or asphalt. Insulation is mounted without additional gaps. Another layer of waterproofing is placed on top of the insulation and hermetically glued. Foil insulation is mounted with a reflector into the interior of the room. Special lathing serves as an additional element of support for the subsequent decorative decoration of the ceiling.

Stopping on the choice of insulation, it is necessary to take into account tips and recommendations, as well as a number of conditions and characteristics of the base material.It is necessary to analyze the construction material (concrete, brick, wood), as well as the size and purpose of the room.

Highlight the basic properties and characteristics for insulation of the ceiling:

• High level of fire safety (the material should not burn).
• The elasticity and elasticity of the material play an important role in the preservation and restoration of insulation.
• Environmentally friendly insulation (the main composition of the material should not contain harmful and toxic substances).

The durability and the long period of operation of a heater depend on it. Thermal insulation of ceiling structures in private houses is carried out upon completion of the main construction works.

Before finishing, it is necessary to insulate the walls and flooring. The main process of insulation is performed after the construction of the house. The design should sit down completely (this occurs within 6 months). After this period, the roof of the house is insulated.At the end of the work, insulating materials with waterproofing are mounted on ceiling structures. Experts recommend leaving a small gap between the insulating material and the roof for air circulation.

The finished ceiling construction can reduce heat loss by up to 10%. As a result, the owner of a private house will significantly save on heating, will feel cozy and comfortable while being indoors. The process of warming requires diligence and responsibility. From the effectiveness of the work performed will depend on the cozy atmosphere in the house. If there are certain doubts and uncertainty in their own abilities, insulation of the ceiling should be entrusted to experienced professionals.
