Technology of mineral wool insulation facade is very important to maintain strict compliance with all requirements. Small things should not be here. Hurry and illiterate spent working, you can get an excessive accumulation of moisture, which is fertile ground for the development of mold. It will be black mold. What material is better to conduct insulation, how to do it, and will be discussed in this review.
Works related to the thermal insulation, are widespread today. Since effective thermal insulation of facades mineral wool can achieve substantial savings. On the costs associated with providing home heat, a lot of money is going. In a house or apartment warming can be performed in-house. But for multi-storey buildings, will likely have to involve experts.
Which is achieved by high-quality thermal insulation of the walls?
Properly insulate walls is possible to obtain a number of positive aspects:
- In the room are comfortable. It can significantly save on heating, which gives a certain economic benefits. If properly organized process of warming of facades with mineral wool can be done to achieve the required indoor temperature. In winter, this room will be warm and in summer to protect from overheating.
- If there is no insulation, it will actively proliferate fungal flora and the wall just covered with black mold. I must say that to get rid of it later is not easy. Mold development adversely affects the health of people. This is especially true for children and the elderly, as well as persons suffering from allergic reactions.
- If done correctly, warming from the inside with mineral wool in the room will not accumulate excess moisture. In addition, you must install the high-quality radiators and old frame, it is desirable to replace the three-compartment plastic bags. Such works need to perform not only in the apartment, but also in the loggia.
- The term mineral wool duty. The manufacturer claims that it will last at least 50 years, if there are no negative impacts.
Mineral wool as insulation to like not only people, but also rodents. When laying mineral wool sure to leave a small air gaps that do not allow to collect the condensation. Thus, trying to avoid excessive moisture inside. But this space are rodents. There are several ways to protect yourself from rodents:
- Process material lime or borax solution.
- Place the heater into the dry pine branches, peppermint, wormwood, or ash.
- Fit the metal mesh in place, which can penetrate the mouse.
First we need to understand what are the types of material, and how they differ.
Kinds and features of mineral wool
Modern construction market is now able to offer a large amount of insulation options. But a lot of interest so far is a material such as mineral wool.
The process of obtaining a rather difficult, but in the end it turns out pretty good material for thermal insulation of facade of the house inside and out. Mineral eutectic during production is stretched to form the finest filaments, cooled and crushed. Such material has a very low thermal conductivity. Mineral wool is classified in many ways. One of the criteria underlying the classification is the starting raw material from which it is made. Depending on this, the following types of mineral wool:
- Stone. It includes basalt, porphyry and granite. It is distinguished by high quality. Mainly used where high strength is needed for a long time.
- Slag. The basis for its production are steel waste. On the quality of this kind of stands on a step lower than the previous version. Not tolerate sharp temperature drops. It is also undesirable for him to high loads and humidity. Basically it insulated sheds, temporary buildings, summer houses and other similar building structures.
- Glass. The basis for the glass is melted. The composition is also administered ash, limestone, dolomite. Such insulation has increased resistance to excessive vibrations. The material is well suited for facilities facing higher fire safety requirements.
In finished form is released consumer mineral wool rolls, mats or plates. Standard sizes in the mineral wool slabs are as follows: 100 x 50 cm.
Tip! Prefer bloc heater, since the density of mineral wool rolls for thermal insulation of walls is much lower.
For greater strength fiber material is treated with compositions of special binders. If you need to warm a large area, then this is done using special mats mineral wool.
Where this material is determined by the degree of its rigidity will be applied. If the wall insulation is carried out from the inside with mineral wool, that are mostly milder form. It uses the frame structure. For external insulation are generally rigid and semi-rigid. This is due to the fact that the outside of the structure is subjected to high mechanical stress.
Positive and negative sides in the application of mineral wool
Like any other building material, it has its pros and cons:
- It does not deform or change shape during sudden temperature changes. Therefore, it can be used in all climates.
- Mineral wool is inert in its composition. It is characterized by high biological and chemical stability. In contact with metallic corrosion products does not occur.
- Work with it very easily. It can be cut with a knife, or cut it with a hacksaw. This simplifies work on insulation.
There are some negative points:
- If the finish is a material having a low vapor barrier properties, condensation will accumulate within wool. It is not excluded that it will lose its geometric forms. To avoid this, at warming of facades it is necessary to cover the membrane film.
- Working with mineral wool should be carried out using personal protective equipment. The kit includes goggles, gloves, respirator. If they do not use, the dust that stands out wool, can get into the respiratory tract.
To achieve the desired effect, it is necessary to choose high-quality insulation.
What is mineral wool select
By the choice of material should be approached very responsibly, and be guided by it should be specific criteria:
- Thermal conductivity. From this figure depends on how the house will be warm. The lower the score, the lower the costs incurred by the owner of the premises for heating their homes.
- The thickness of mineral wool for insulation of facade walls. If the installation carried out correctly, the use of the term is not limited timeframe.
- Permeability to steam. High coefficient provides a vapor barrier having such circumstances under which the plaster on the front, applied wet, dry very fast.
- Fire safety. Comment this property is probably not necessary.
- The density of the mineral wool. From this parameter depends on the weight of the insulation, and therefore its cost. The higher the density the more expensive material.
- If insulated façade with frame structure, it is necessary to use the material, which is composed of rocks and glass.
- If the insulation is expected increased load, it is necessary to pay attention to such indicators as resistance.
- Used for thermal insulation inside the basalt wool or fiberglass. In addition to insulation, it is achieved more noise absorption effect.
After the acquisition of insulation, it is possible to start the installation. It is important to distinguish between the stacking technology for interior and exterior walls.
internal insulation
Sometimes, for various reasons it is impossible to insulate the facade. The way out of this situation is the insulation of the walls from the inside. The process is not very complicated and it can be done independently, without involving, assistants.
Initially prepared surface intended for warming, and tools.
You will need:
- Putty knife. Essential for applying glue and putty.
- Hand saw or a knife for cutting the material.
- Drill and mounting material for the frame mount.
- Sandpaper for grouting.
- Level and construction bucket for mixing glue.
The first in the course of attending a spatula and building cleaner. Dry the wall by using a special dryer. If there is a need, the walls are subjected to antiseptic treatment.
It is necessary to carry out sealing of all cracks and holes. For this purpose the cement mix. Next, primer is applied on the wall. It is applied in several layers, but each successive made only after the final drying of the previous.
At the finish carried out the alignment of the wall. This is done to ensure that the insulation on the wall went to more tightly.
When the frame is used to mount slats of wood or metal profile. The distance between the transverse strips is performed based on what has width roll. It is necessary to make a little smaller. This will provide a snug fit to the wall wool. For insulation partitions interior wall vapor barrier film is placed on top and is held in the horizontal direction. If using foil mineral wool, the overlay layer vapor barrier is not required. The joints must be secured with the help of a construction tape.
Cut wool must be according to the required length, but making allowance of 10 cm. After laying the insulation cover sheet of drywall.
How to make mineral wool insulation walls on the outside with their hands
Work can be done one of two ways.
Wet method. The material is fixed to the wall. Perform this adhesive. In this way usually insulated brick walls and those that are made from concrete blocks. We do not recommend performing insulation when there is rain. Material simply gets wet.
Dry method. Performed frame, and then it fixed rail. It turns crate.
The cell is placed insulation. It turns out, the so-called ventilated facade. For crates can be used timber. Then it was impregnated with an antiseptic.
Important! Always mesh size should be slightly smaller than the width of insulation. This provides a more secure fit and a tight abutment.
On top of a heater is necessary to impose a moisture proof film. Its fixation is carried out by means of double-sided tape. It is also possible for this purpose to use a staple gun. Performing crate, you can achieve two goals simultaneously. Formed peculiar airbag, which further contributes to the retention of heat. Moreover, the frame serves as the basis for a heater assembly. In addition, it will be attached a material that was chosen for the finishing. It can be conducted, for example, siding or clapboard. Some owners for this purpose, asbestos cement slabs.
Having considered the detailed options for insulation, it can be said that the use of mineral wool - a good way to keep your home warm and cozy.
