Full instructions on the insulation of the attic from inside his own hands

To begin let me remind you that the attic - it is attic space, which is equipped for human habitation or any household needs (office, greenhouse, etc.).Depending on the purpose of the building, its layout, such as the attic roof can be of different configurations, but inside the general requirements for the insulation of the attic remain unchanged.

Features and materials for thermal insulation of attics

should be understood that this room, unlike all the others, is colder, because the top has a "heat cushion".Therefore insulation, which we will do with their hands, should be particularly high quality.Based on this, and the material selected.

The difficulty lies in the fact that the surface rough, as the roof trusses are arranged beams, and all have to get.A layer of waterproofing have to withdraw under the roof in order to carried out the condensate drain.The organization of work must take into account that the end walls of the attic also need to cover - through them takes a lot of heat.

Each house has its own architecture, roof shape and the material roofing and walls.Consequently, for each dwelling may be some special, specifying guidelines for insulation of the attic space.Therefore, we consider only the basic, mandatory actions to be undertaken.

choice of material depends on many factors.The design of the roof, the roof, the climate in the area, and much more.We list only some of the features of materials that can be used.

foam

One of the cheapest, and therefore popular materials for insulation.It is easy to process and installation.But experts point out that it has a small vapor permeability.Consequently, the room can be damp.In addition, the gaps between the plates and the foam will increase as the "drying" wood trusses.And this - the slot for the draft.There is one more remark.In this mouse cover often equip their homes, and then the fight will be quite difficult with them.

Styrofoam

preferable, since such a "brickwork" has almost no joints and unattractive mice.

mineral wool Basalt mineral wool

excellent in all respects.With greater strength, it does not absorb moisture, fire-proof and practically does not conduct heat.Since it is elastic, it is well kept in the place of installation, resting their edges in the rafters.Glass wool stronger, and as a sound insulator more effective.It can withstand lower temperatures, however, work with it requires special precautions.

main stages of work on warming

roof insulation

initially laid along the rafters waterproofing.Moreover, over the entire height - from the bottom and up to the roof ridge.However, this is not always done, because the roofing material itself also plays a role of the insulator.If the coating of roofing iron, for example, it would be sufficient.When installing the heater should be aware of its coefficient of thermal conductivity.Such data can be obtained at the point of purchase (as they are specified in the certificate for the products) and on the Internet.Based on this information, a decision is made, to be enough to make a single layer or double-stacking, to avoid possible heat loss.

When installing this material should be remembered that between it and the roof has to be some distance away.This air gap is necessary for high-quality ventilation in place bookmarks insulation.This allows you to protect him and the structural elements of the roof from rotting.

thickness of this layer depends on the coating material of the roof.If he has a wavy shape (shingles, metal), it shall not be less than 2.5 cm. And by using "flat" format (roll materials, sheet steel, asbestos), the distance from the heater to the roof should be doubled.

Another point - the rafters and the thickness of the insulator plates (for example, Styrofoam) can be different.If plate "thinner", the first layer is placed between the rafters, and the second - on the rafters.In the case where the plate thickness, the rafters should fill the wooden slats, deleting such a "drop" in height.The quality of work is not affected.

To protect the insulation material from excessive humidity, superimposed on top paroizolyator.It is known that warm air rises, and where condenses.Therefore, this protection is mandatory.As a material for such a layer of asphalt are used, plastic film, roofing paper, foil materials.Currently for sale a great choice.

Wall insulation attic

This is done in case, if the roof does not reach the floor.First, the walls are fixed slats for laying thermal insulation and next - vapor barrier - layers.Method of production work exactly the same way as described above.But here, you must first put the waterproofing material.By the way, for the walls as insulation fiberboard sheets are well suited.They are easy to operate, as they can be fastened with nails or screws.

-quality attic insulation can significantly reduce home heating costs, it creates a favorable microclimate and increases the service life of structural elements.In addition, the owners have at their disposal additional square meters of usable area.
