Warming of the attic from inside if the roof is already covered: materials and technologies

Improvement of the living space on the site of the attic for a long time ceased to be a rare occurrence. More and more home owners are interested in how to carry out repairs to life "under the roof" was no less comfortable than in the house. Consider how to make the insulation of the attic if the roof is already covered, what materials are best suited for this purpose and what the nuances necessary to pay attention.

Warming of the attic from inside if the roof is already covered: training facilities

Attic - it is not just a lived-in attic. There are some rules that distinguish these two spaces from each other. In the first place, the roof of the attic have to be sloped. Also mounted norm room height should be at least 2.5 m.

Focusing on attractive appearance, many decide about the arrangement of the attic. But in reality, we have to deal with some nuances, become familiar with which one wants to before the start of works:

• materials used for the construction of the attic, directly determine the further heat loss in the room. Therefore, their choice should be approached very seriously;
• no less influence and correctly selected engineering solutions that allow on the top floor all the necessary communications;
• essential role played by the shape of the roof. It can be a pent, saddle or broken;
• to hide the load-bearing elements of the roof, will have to show imagination;
• attic can be placed not only in homes but also go beyond it, based on the columns.

Each of these aspects has its influence on the approach that will be needed for high-quality thermal insulation of the roof. But the main role still belongs to two basic materials - heat and waterproofing. On the one hand, the space under the roof is in the coldest zone of the structure. On the other - a strong difference between the temperature inside and outside often causes condensation, which is destructive effect on materials.

The best materials for insulating the attic with his own hands

there are plenty of suitable options for the internal insulation of the attic. But the choice should be done based on the characteristics of the region of residence, as well as the specific features of the roof structure with which to work with. We consider what options exist today and what features are characteristic of them.

Warming of the attic with foam: the pros and cons of the material

Foam - one of the most famous of heaters, which occupies a niche among the inexpensive insulating materials. Its price is really much lower than that of many others, but this is not its only advantage:

• foam totally absorb moisture. If the material is pretreated specially designed for this impregnation, the water will merely flow down along the surface down;
• light weight - another advantage, which greatly facilitates transport and installation, and also reduces the load on the roof;
• the foam thermal conductivity is very small, so that with its direct functions, he manages more than full;
• foam is easily cut and fastened. This allows you to easily work with him even in the absence of any experience.

Interesting!At a cost of this method can only be compared with the ceiling insulation expanded clay, but now this method is still rarely used.

Based on these characteristics, we can conclude that the foam - almost a safe bet when it comes to insulation of the attic from inside. But wall insulation foam from the inside also has shortcomings, and sometimes they turn out to be much more significant advantages:

• water vapor permeability of the foam is at a very low level. As a result, the room is often stuffy and hot. It also leads to an increase in humidity, causing the development of mold and mildew on the wooden elements of the roof;
• despite its artificial origin, this material is often subjected to damage from rodents;
• eventually timber has a property to shrink, resulting in the formation of gaps between the elements of the foam. Fix it is not possible, and the only way to solve the problem - a complete replacement of insulation material.

Many believe that these shortcomings more than the benefits, and attic insulation foam is not justified. But one must admit that this is one of the most low-priced option that minimizes the hassle, and subject to installation technology, may well be an alternative to more costly solutions.

Thermal insulation of attic polystyrene: advantages and disadvantages especially

Extruded polystyrene foam is very similar to. Their specifications are almost identical, except for one significant aspect - installation technology. If foam must be laid between the rafters, then put on top of styrofoam, which eliminates the risk of cracks and gaps.

Useful advice!Some manufacturers offer customers plate with staggered joints, allowing you to make the joints more robust and reliable. This fixation elements together - ideal for mansard roof insulation.

Among other advantages polystyrene foam roof insulation should be noted its light weight, which is combined with high strength and resistance to external influences. In addition, the service life of the material is quite large, provided that the entire attic insulation technology Penoplex.

Expanded polystyrene is not prone to the processes of decay or decomposition, which is also important in the case of work on the roof. Over it, any topcoat can be applied, which give an attractive appearance and provide additional security.

Work with polystyrene own simple: it locks fit a variety of adhesive mixtures and compositions. And in some cases, even use staple gun. So for installation no need to purchase any expensive additional elements.

But all these positive characteristics we can not forget about a single, but rather serious disadvantages polystyrene insulation inside the walls and the roof - the material has an elevated level of combustibility. For owners, this means the need for more careful and thoughtful summing up of all utilities, particularly electricity.

Of course, manufacturers are trying to reduce this drawback to a minimum, but today we can say with confidence that this issue remains open, and each owner has opted for thermal insulation of walls inside Penoplex is obliged to take care of their security.

Interesting!It is no accident that most all other material is chosen for insulation balconies. Expanded polystyrene has a very low thermal conductivity, and thus on the balcony it practically does not have contact with electricity.

Insulation of attic with mineral wool inside: a worthy alternative Penoplex

Mineral wool - another heat-insulating material, which is used everywhere and is widely known due to its characteristics. It received its name because of the fibrous structure, similar to medical cotton wool. Buy it can be in rolls, which makes transportation and installation more convenient.

Low thermal conductivity is combined not with the ability to absorb moisture. Although, if it happens, the material dries quickly without losing its appearance and specifications.

Mineral wool is classified as an environmentally friendly and safe materials, it becomes evident even in the event that the upper part of the roof is covered with metal, which tends to become hot under the influence of solar rays. In addition, mineral wool is also sound-absorbing barrier, and in contrast to the foam, it is not of interest to various rodents and insects.

Warming of the roof from the inside with mineral wool should be done taking into account the fact that it is quite elastic material even though its original soft fibrous structure. It is quite able to be held between the rafters provided qualitative fixation.

Useful advice!In the process of cutting of mineral wool for stacking sheet between rafters must be left margin of about 2 cm. This will allow them to be held and not to fall, even in the absence of additional connectors.

Warming of the roof inside the glassy: whether to use this material

According to its characteristics similar to the glass wool mineral wool, but in this case the fibers that make up the material are more in length that generally increases the elasticity of the material. Slightly higher performance and durability and sound capabilities. But when in contact with moisture inferior wool mineral wool, absorbing more water.

The use of glass wool for insulation of residential premises does not lead to any negative consequences for the health of residents. No toxic substances in the production process are not used. In addition, glass is characterized by low flammability.

In operation, the material required to comply with security precautions to avoid getting air into the glass fibers. Its fine particles can cause irritation, so use of a respirator and protective eyewear is mandatory.

Useful advice!Sometimes glass fiber can cause skin irritation, so in the process of working with it is recommended to wear closed clothes, and even gloves.

Warming of the roof inside the attic with his own hands with the use of stone wool

Stone wool - the most expensive option among similar materials. But at the same time it is very safe for human health and is much higher than all other options on the degree of reliability. Here are some of its main advantages:

• the thermal conductivity coefficient of this material is one of the lowest;
• stone wool is completely environmentally friendly, even when heated;
• This thermal insulator layer is also excellent sound barriers;
• vapor permeation level is very high;

• material is substantially not illuminated;
• no mechanical loads are not capable of deforming rock wool or affect its performance;
• material characterized by long service life;
• buy stone wool can be in the form of plates that can be easily cut to the desired length and attach to the ceiling surface.

Due to the high cost of stone wool it will often try to replace by means of mineral wool or glass wool. But such a change can not be considered complete, since the quality of the insulation is reflected quite seriously. Many users claim that the price of the material is justified, and, subject to installation technology, it quickly pays for expenses provoked.

In addition, it is possible to carry out all the work on the roof of the attic insulation from the inside by hand. Video instruction can demonstrate the procedure of work, and the recommendations of experts will help to avoid common mistakes.

Warming of the attic ecowool - one of the most effective ways to combat cold

Ecowool - pre-crushed material which is blown in the first slot, and then by means of the same method, a layer placed between the ceiling and rafters, using a specially designed for this device. This is an expensive procedure, but it allows you to completely eliminate all risks of drafts and ensure the most efficient insulation.

Ecowool 80% consists of a natural material - paper, whose properties are very similar to those which are characteristic for wood. When their natural origin, reduces the level of heat loss ecowool no less effectively than other materials.

One of the components, which is part of Cellulose Fiber - drill. According to its characteristics it is a natural antiseptic origin that allows Wooden roofs effective protection against the formation of mold and mildew.

Ecowool applied a thin layer, but it provides an adequate level of not only heat, but also the soundproofing. Its features material retains even after decades of use. So do not be too low cost - the only drawback of this material, which is justified by its excellent properties.

Warming of the attic with polyurethane foam: the basis of the technology and features of the material

Polyurethane foam - this is the most modern of all these methods to insulate the attic. Its main difference in the total absence of joints or gaps that may be a source of cold air. In addition, the operational period of this material is one of the longest, and up to 30 years.

Polyurethane foam does not shrink, even if over time the wooden roof of the house begins to slowly deform. Its solid structure eliminates the risk of absorption of moisture, which eliminates the need for installation of additional vapor barrier.

But there are also aspects that significantly complicate the process of using polyurethane foam as insulation of the roof from the inside. First of all it concerns the application of the procedure, which requires complicated and expensive equipment. Its purchase is almost never justified, so it is usually taken on lease.

Another aspect - the application of sophisticated technology, which provides for a certain amount of experience work in this area and does not allow newcomers to cope with the task qualitatively.

Useful advice!Ideal - to invite a team of workers who come with their own equipment and just a few hours to make a quality insulation of the attic of your house.

Warming of the attic from inside his own hands, using penofol

Penofol - a kind of polyethylene foam - technology that takes its place among the ways of modern thermal insulation of walls and houses. Along with high insulation, it is worth noting also that penofol has quality coating of aluminum which may be coated on one or two sides.

Here are some arguments in favor of using penofol for insulating the attic:

• material poses no threat to human health or the surrounding environment;
• indicator of its thermal conductivity is very low;
• closed system of air bubbles characteristic of this material is an excellent barrier to the penetration of steam.

This method also does not refer to expensive and requires the implementation of significant investments. But, as practice shows, it is better one time to invest in high-quality material and thereby provide comfortable living conditions for many years ahead.

It is not uncommon, and the combination of materials. Matching the characteristics of materials can be used for thermal insulation together. For example, the perfect combination between a mineral wool and polystyrene. First placed between the rafters, and the second is closer to the edge of the roof. This combination will achieve the desired effect and significantly save on the purchase of materials.

As can be seen from the descriptions, each heater has its own advantages and disadvantages. The only question is how to choose the most suitable option that will satisfy the reporting compliance rates and quality material.

One of the most common mistakes made by the owners - a rash opt for the cheapest option for attic insulation. Videos and articles can demonstrate the positive aspects of a decision, but you must choose taking into account all the nuances and characteristics. Attempts to save on heat-insulating material can lead to the fact that after some time of operation, it is necessary to carry out repairs or even replacement of the entire material.

Warming of the attic from inside his own hands: video and stages of work

Each material has its own characteristics and attachment should be used only in accordance with the manufacturer's recommendations. But if we talk about the general order of work, then there are mandatory steps that are carried out almost always, regardless of the selected material.

The first laid layer of waterproofing material which is to protect the insulation from the destructive effects of moisture. Film overlapped so that one layer is on the other 10-15 cm. Attach material using the staple gun, and place further joints glued tape.

Then, if necessary, creates a crate. For it is possible to use wooden slats having a width of 8-10 cm. They must be fastened to the rafters, placing parallel to each other at a distance of 50-60 cm. It is important to inspect each item separately using the building level. This will prevent the appearance of any defects in the roof of the future.

On rafter or purlin heat insulator is placed and fixed manner suitable for him. For example, in the case of the use of any type of wool sold in roll form, the material is cut to the right size to put them between the rafters. In this case the thickness of the insulation must be such as to match the width of the joists. It is especially important if you decide to make wall insulation from the inside with mineral wool plus plasterboard. In this case all the free space should be filled with insulation.

The upper layer of the "pie" - a layer of vapor barrier material, as which may be used in plastic film, roofing paper or glassine. As in the case of waterproofing material selected lapped fit. However, in this case, the attachment is better to carry out with the help of thin wooden strips, placing them in increments of 40-50 cm. All joints necessarily glued shut.

Useful advice!If you require any laying several layers of insulation material between each of them is required to lay insulation film. This is especially significant for cold regions.

As a final step can only take care of a suitable finishing coat, which can be attached to the crate or in the case of its absence, directly to the bars. Into account not take the weight used decorative panels, because the installation of the heaviest of them may require a prior installation of a metal frame profiles.

Major mistakes made in the process of insulation of the attic

The end result of the work being done by the hands, is directly dependent on how well respected technology and all the prescribed rules. It is particularly attentive to the process of laying the waterproofing layer as materials, which are able to absorb moisture in the future is already dry, which often causes cold in room.

Here are some guidelines from the experts, that you can use to minimize the negative effects:

• if the roof angle is not greater than 13 °, this will cause the delay of precipitation on the surface. As a result - the occurrence of rust and leakage occurrence. All this can have a negative impact on the condition of the insulation, so it is important to make sure that the tilt angle is large enough, before you start to work;
• installation of thermal insulation material on the walls and the roof - it's not all the necessary work. You need to take care of the insulation windows (for Swedish technology). To do this, it is best to invite experts to certainly avoid leakage. Especially if required the installation of windows in an inclined;

• to provide thermal insulation material to dry out and the possibility of aeration in the case of wetting, it is desirable to leave between the material and the roof a gap of about 2-3 cm;
• absolutely can not miss at least one of the required layers of vapor or moisture-proof materials;
• if the insulation material thickness exceeds the rafters, their height can be increased by an additional rack stuffed yourself.

These simple guidelines can help in the process, significantly improving the quality of insulation. However, if for any reason there is any doubt in the abilities and experience would be better to invite a specialist. Of course, it will have to pay, but in this case do not have to redo everything twice.

Warming of the attic gable on the inside - is not the most difficult task that may face the owner of the house. Often on the top floor of the owners are willing to arrange a balcony, which insulation technology also has its own characteristics.

As for the walls, a variety of materials can be used for ceiling insulation on the balcony, although it is worth noting that there are often applied insulation technology loggias, which have not been I mentioned. Details to deal with the peculiarities of this process will help you to understand step by step instructions "Warming of the balcony from the inside with your own hands."
