Ceiling insulation: where to start?

In a private house or in a country house, you want to create an environment where it will be warm and comfortable, but sometimes the heat from the house leaves the street because of the cold roof, so many begin to look for the answer to the question - how to insulate the ceiling in a private house. There are many types of insulation materials, which have their own characteristics.

Varieties of materials

The ceiling is insulated in a house with a cold roof using thermal insulation materials. When choosing insulation products, consumers are guided by the following properties:

• Heat conductivity - this characteristic affects the heat transfer through the ceiling surface. The lower this figure, the better the material.
• Resistance to humidity - the indicator is evaluated when warming the roof from the outside.
• Service life - provides a long period of use when warming.
• Environmental friendliness - the impact on the body is assessed.
• Flammability - thermal insulation should not ignite when located on wooden roofs.

The following materials serve as insulation materials:

• Sawdust;
• Expanded clay;
• Stone wool;
• Ecowool;
• Styrofoam;
• Clay;
• Styrofoam.

Professionals believe that it is better to insulate the ceiling of a private house with the material that is suitable for the base of the roof, otherwise you can achieve the opposite result. Technological features of insulation depend on the category of overlap. The basis of concrete involves the use of high density materials or heat insulation materials with a large weight. For wooden ceiling ceilings, the best materials are lightweight filling agents or rolled insulation.

Insulation methods

There are various methods of insulation, suggesting a variety of insulation of roofs of houses. You can do the insulation of the ceiling with your own hands.

Use of sawdust

Many people wonder how to insulate the ceiling with sawdust? Warming the ceiling with sawdust was common in the last century. When the woodworking enterprises are located near houses, it is possible to purchase materials that serve as insulation for the cold roof for a small cost.

It is recommended to heat the ceiling with sawdust on wooden floors. The disadvantage of this material is high flammability. This quality is offset by the use of numerous insulated technologies.

If you use sawdust as a heater for the roof, then you should correctly select the size of the layer. Insulation of the ceiling with sawdust consists of the following stages of roof insulation:

1. Smearing a wooden floor with a clay solution of liquid consistency.
2. Sand filling to prevent damage to the insulation layer.
3. Application of a mixture of carbide and slaked lime to prevent mice from eating insulation.
4. Falling asleep sawdust.
5. Powder waste slag to avoid fire.

After the last poured layer, it is better not to lay anything. If the use of an attic is intended, then planks can be laid.

Using insulation of the ceiling with sawdust, you can apply a film for waterproofing. After laying it on top of the surface, then pour a mixture of sawdust, cement, water in a ratio of 10: 1: 1.5.The thickness of this layer is 20 cm. Cement can be replaced with clay. You can still use a similar method of warming without pouring slag, and grease the laid layers with clay.

Clay as a heater

Insulating the ceiling with clay implies the formation of a layer with a thickness of 0.5-0.8 m, but the ceiling area is not able to withstand such a weight, therefore, a composition of sawdust and clay is used. At the end of laying the prepared solution in water, it is necessary to dry the space and again cover the floor with clay to remove possible cracks.

The use of expanded clay

Ceiling insulation with expanded clay has the advantage of incombustibility of the base. In addition, expanded clay does not cause allergic reactions. Warming should be made with a material with particle size parameters of 0.4-1.0 cm. Warming of a wooden ceiling with such a tool is not recommended due to its high weight.

The correct technology for using expanded clay involves preparatory work. They consist in cleaning the surface and placing the vapor barrier film layer on the ceiling from the outside. Further, the insulation of the concrete ceiling occurs according to the scheme:

• Laying a layer of clay on a film located on the ceiling;
• Expanded clay filling (a mixture of oversized particles has the best effect);
• Making a screed with a thickness of 5 cm from a mixture of cement and sand.

Insulation of the attic ceiling in this way will add strength to the ceiling. You can put heavy objects in the room.

The use of mineral wool

Thermal insulation of mineral wool is the most common way to prevent heat leakage in attic rooms. Who insulated the ceiling with this material, notes its harmfulness due to the use of formaldehyde resins in the manufacture.

Insulation of the ceiling with mineral wool suggests the following scheme:

• Before using mineral wool, the concrete ceiling area must be leveled;
• To cover with a film a draft ceiling;
• Laying mineral wool;
• Flooring equipment made of plywood or boards.

Insulation of the ceiling with mineral wool eliminates the screed on top of mineral wool due to reduced thermal insulation of the concrete ceiling.

Insulating the glass wool ceiling (a type of mineral wool) for a cold roof made of wood consists of the steps:

• A vapor insulating material is placed between the beams on the roof to prevent loss of mineral wool properties;
• Cutting pieces of glass wool, exceeding the size of the beam by 20 cm, or when making the roof, already make large holes for laying cotton;
• Laying glass wool on the ceiling;
• Laying a wooden floor.

If the attic is supposed to walk on the floor, then glass wool is covered with floor material without fail. The correct laying of boards on the ceiling area is carried out with the release of the interelement distance of 0.3 cm between the insulation and the board. Insulation of the ceiling in a wooden house with mineral wool is carried out using a material thickness of 10-25 cm.

Foam application

Insulation of the ceiling with foam can be done inside and out. The insulated ceiling with polystyrene inside is found in apartment buildings. You can use the insulation technology in the house from the inside for sound insulation between the apartments. In order to reduce the heat transfer of a cold ceiling, the use of foam is carried out from the attic in a private home. Insulation of the ceiling with foam implies the use of a waterproofing layer on the cold side and a layer of vapor barrier from the inside of the room.

How to insulate the ceiling with foam? Scheme of work:

1. Clearing a cold ceiling and laying a vapor barrier;
2. If necessary, the construction of a lag;
3. Material laying;
4. The implementation of the waterproofing layer;
5. If the insulated attic floor surface is made without logs, then screed must be filled;
6. Laying a clean floor.

A proper insulated ceiling does not require laying the floor if there is no walking on the surface.

How to insulate the ceiling in a private house from the inside? The answer is simple - polystyrene. In this case, they insulate according to the scheme:

1. Surface cleansing;
2. The implementation of the frame (using wooden or aluminum profiles);
3. Fastening foam on the draft ceiling;
4. Performing vapor barrier;
5. Sheathing.

Insulating the ceiling from the inside involves plasterboard cladding or the installation of suspended ceilings.

Insulating the ceiling in a private house with your own hands in the described way is easy. However, the base has high combustibility and emits toxic substances during combustion, so you can use it as a ceiling insulation in a garage or as an option to heat the ceiling in a cellar.

The use of penofol

Insulation of the ceiling with penofol is used in those situations when the room retains heat, but there are minor losses. Penofol is a foamed polyethylene. In this way, the ceiling is insulated in the apartment.

The method involves warming the cold ceiling of the room from the inside. How to properly insulate the ceiling in a wooden house using penofol? Work Stages:

1. Organization of the crate;
2. Fastening the material so that the side with the foil applied is located inside the room (nails can be used);
3. Finishing.

In private homes, ceiling decoration can be done with plasterboard or false ceiling. It is better to install suspended ceilings in the apartment in order to save more space.

Unlike the stone wool method, this method involves leaving ventilation gaps on both sides of the penofol. Many people wonder how to insulate the ceiling in the country, if you want to use penofol. You can combine this material with foam. Penofol in this situation is fixed in front of a layer of drywall.

Ceiling insulation in other buildings

Insulating the ceiling in a cold-roofed bathhouse involves the use of lightweight fire-resistant materials. For a bath, mineral wool and expanded clay are often used. The use of foam when warming the ceiling of the bath is not effective due to its increased fire hazard. In the process of arranging the insulation of the ceiling surface of the bath, it is required to lay a layer of hydro- and vapor barrier.

How to insulate the ceiling in the bath with your own hands, if the location of the attic is not assumed. Then it is necessary to place a vapor barrier before the insulation. At the end, install boards on the ceiling of the bath.

How to insulate the ceiling in the garage? Mineral wool and polystyrene foam can be used. Polyfoam is applicable even in a situation with a metal garage. It will serve as additional soundproofing material for the garage space. If the cellar ceiling insulation is required, then the location of the steam-waterproofing layer, as in the situation with the bathhouse, is a prerequisite.

The ceiling insulation on the balcony is best done with the use of foam or polystyrene. The insulation of the ceiling on the loggia is also economical to use with the use of foam. Moreover, the ceiling of the loggia or balcony is conveniently sheathed with these materials. If you want to use stone wool on the loggia of the apartment, then you should think about the action of allergic components. How to insulate the ceiling on the balcony? The work process is built similarly to the methods described:

• Installation of the crate;
• Material laying;
• Finish.

When creating a bathroom insulation in a private house, the described materials are also used, but you should choose materials for steam and waterproofing with high quality indicators. When the bath is located in a corner room, it is better to insulate the ceiling from the street and from the inside.

If the roof of the house is properly insulated, then heat will always be present. Given all the features of the operation of materials, it is possible to achieve long-term effective thermal insulation.
