Save a warm atmosphere in your home is quite a difficult task. Is not only insulate the floor and walls. You can not leave without attention and ceiling. On the market there are a large amount of insulation for the ceiling of the house. One of the most popular is rock wool. How to install and insulate, consider the article.
Advantages of mineral insulation
Why most people opt for mineral wool? This is due to the fact that this heater has more pros than cons. Positive mineral wool quality include:
- Affordable price;
- Convenient use;
- Not afraid pests (mice and rats);
- It does not rot or grow moldy;
- Fireproof material;
- It has noise insulation properties;
- Good water vapor permeability;
- Eco-friendly material;
- It has improved strength;
- The thickness of mineral wool may be different.
Because of these qualities of mineral wool - the best material for the thermal insulation of the ceiling. But as with any material, it has its drawbacks:
- It can not be subjected to creasing and tamping. This reduces its thermal insulation properties;
- Minvata afraid of water. When wet loses its properties.
This type of insulation is used in combination with other materials - plastic foam and plastic film. Thermal insulation in so doing will be reliable.

Kinds and features of mineral wool
fibrous materials used in the insulation space. They can be of vegetable (eg, cotton) and mineral origin. Only mineral fibers do not burn, so the building is used by them. Minerals suitable for the extraction of the fibers is small. These include glass, rocks and some toxins. Accordingly, there are three types:
- Glass wool. It is made of limestone, dolomite, sand, borax and cullet. Has low thermal conductivity, it tolerates vibration. Plastic material, while the carriage can be compacted without risk of loss of properties. It is produced in the form of plates and cylinders for insulating pipelines. It has a low cost. Leaders in the manufacture of glass are «Isover», «KnaufInsulation», «Ursa».
- Basalt wool. This insulation is made of diabase, basalt, gabbro. On their basis it is possible to obtain materials with different densities, shape. Accordingly it is possible to vary the resistance to mechanical stress. The thermal conductivity higher than that of glass. You can create different density of glass wool, which makes it possible to make it flexible and durable and tough. Flexible articles of stone wool used in small buildings. Also, a heater such density insulated wells and pipelines. It is used in environments with low mechanical stress. Thinner basalt wool used in private homes and for insulation communications. If the wool is reinforced with a metal wire and has a large thickness, it can be used anywhere. It keeps the room warm, fire. It helps to reduce the penetration of outside noise. Shaped products of this heater tubes and treated wells. At high mechanical loads using a hard basalt wool. It is strong in the gap, which allows to use it, insulating sheets code need to bond together. Basalt may have a base foil or glass filaments. To make it stronger using metallic threads. Basalt wool produced: Rockwool, Paroc, Nobasil, Danko-Izol, Technonikol.
- Slag. Made of waste in the melting of pig iron in blast furnaces. It has a high thermal conductivity. The downside is that it readily absorbs water. Therefore, for wet areas and facades do not use it. Also slag has a low resistance to vibrations. To date, used in the construction is extremely rare.
Each type of mineral wool has its advantages. It is important when choosing to use the knowledge about the type of premises, its size and purpose.
The layer of mineral wool for insulating the ceiling
Quality of the insulation material is determined by the density of the fibers, thermal conductivity and resistance to moisture. Due to its properties, mineral wool is increasingly used in the construction. Its characteristics are different types of mineral wool for ease of use. Since wool can cause itching of the skin, and slag wool fibers are quite prickly. Ceiling better to choose basalt wool.
Thermal insulation of the ceiling is best done from the rooftop of the coating. Better insulation laid in 2-3 layers, to cover the joints. Technology of warming of any mineral wool ceiling is quite simple.
How to fix mineral wool ceiling
Mineral wool fastened to the ceiling is not difficult if you know the right technology. If carried out by the external insulation of the attic, the cotton sheets lay between joists overlap. Be sure to leave a distance between the insulation and vapor barrier film. To when pulling wool is not sags and does not slide down, its pull on the frame of the twine. Then the stuffed and rake ceiling plasterboard or other material. If the ceiling is solid or concrete, then it becomes a crate of metal sheets or wooden bars. Step between the guide should be 57-59 cm. Next laid mineral wool. Then it clips sewn vapor barrier. Next is a layer of plasterboard or other finish. If there is ventilation in the ceiling, the vapor barrier is not required.
If you want to keep the height of the ceiling, the insulation is secured directly to the ceiling without battens. Possible for fixing mineral wool ceiling Apartement to use anchors or adhesives.
insulated with mineral wool ceiling with his hands
How to properly insulate the ceiling in the home? Perform insulation ceiling on its own - the task is quite doable. Moreover, that mineral wool insulation greatly simplifies the process. First, you need to decide which side will be made of operation: internal or external. External insulation is made in the presence of attic.
The main stages of the external thermal insulation of the ceiling:
1) is made of lath-like bars or metal sheets. Cross section must be selected according to the thickness and density mineral wool.
2) lays down a vapor barrier. As it is most commonly used foam, thickness 5 cm is sufficient. Fastening is carried out using counter-.
3) Next, the insulation is laid itself. In the joints better make 2 layers.
4) A stacking waterproofing layer. For fasteners most often used construction staples.
With proper selection of materials and tools with external insulation of the ceiling handle even an inexperienced builder.
Internal insulation of the ceiling. The nuances of installation
For this kind of insulation often resort buildings, with the second and subsequent floors, city apartments, shops and other commercial buildings. The process of insulation is simple, so you can make it with your own hands. Installation steps:
1) On a ceiling mounted waterproofing layer with staple gun. The seams between the sheets is better to close by means of the reinforcing tape. Waterproofing is used in the case, if the ceiling is wooden.
2) Collect crates. The cross section of the bars and the steps therebetween chosen with regard to the thickness of the mineral wool is wool. Fastened with screws or dowels can be.
3) Placement of a conventional mineral wool ceiling. Attach you can glue or staples. How best to secure the mineral wool on the ceiling? If used wooden crate, the layer can be additionally fixed by means of nails or ropes. Skip rope for a snake to hammer a nail. This insulation insure against removal due to moisture, or vibration.
4) Mineral wool closed isolating film layer by means of staples.
5) Set a counter lath for mounting topcoat.
Installation of insulation on the inside has a lot of steps, but do not need to implement them specific skills. Well-chosen tools and fasteners will facilitate the work. These include: screwdriver or a drill, screws, dowels, stapler and braces, reinforcing tape, adhesive tape.
In private homes and cottages often use a combined method of insulation.
When working with mineral wool should use a respirator and protective gloves. This will help to protect the respiratory tract and the skin from the finest wool particles. If the installation batten any gaps due to irregularities of the ceiling, then it is better to cover with foam to avoid drafts. It happens that the thickness of the bars is less than needed for wool. Not worth the crease heater, it is better to increase the additional bars. The result of this work can be checked with a thermal imager. This will eliminate mounting errors before applying the finishing coating. Not necessarily to buy a professional instrument. For many smartphones released a special app that will be no less effective.
If you pay attention to the choice of materials and observe the installation steps, insulation will prevent the ceiling premises from mold, mildew and frost. It is well insulated house - a place where a comfortable and pleasant stay.
