rare urban dwellers today are not dreaming of his country house.And if you're lucky, and you become its owner, in most cases, sooner or later you will want or need to do repair it to make your home as easy as possible.

One of the main conditions of comfort in the house will be a reliable roof.You agree that even in the most beautiful interior can hardly feel comfortable if the roof leaks.

And, of course, the roof should be reliable in all respects.The roof needs to retain heat in the house and to protect it from unnecessary moisture.Therefore, a prudent owner of the house, in the construction or repair of a roof, be sure to take care not only about the good roofing material, but also on the quality of hydro and thermal insulation of the roof.Which, incidentally, will allow it in the future to save a lot of money in the operation of his house, since heating costs will decrease, and the number of repairs accurately reduced.Especially because the heat loss by 20-30 percent going right through the roof.

various insulating materials there is now an enormous amount.To be guided in their selection should be on the price of the material, and, significantly, its performance characteristics, the ability to resist the effects of a different sort, from the climate to mechanical loads.

Choice hydro or thermal insulation materials also depends on the shape of the roof.It can be flat, single or gable, hipped, hipped roof or attic.

Today widely used have the insulation as polystyrene plates, rigid fiberglass boards, foam glass, foam and mineral wool.All of them have different degrees of thermal conductivity, environmental, water absorption, water vapor permeability.It should also take into account a number of other options, the price to the strength properties, the nuances of which, of course, known in the art.Therefore their opinion when choosing insulation have to be taken into account.

But perhaps the most common, and in many respects the best insulation for today are mineral wool boards.They can be used in all types of roofs.This material is not actually burn (even withstand temperatures over 1,000 degrees).It has a low thermal conductivity and water absorption, other materials less subject to deformation, does not allow to accumulate pair.Plus: to protect the room from the outside quietly.

insulated flat roof can be external and internal way, in two layers, or one.The first method is easier to implement, but here requires careful consideration of a variety of parameters.For example, if the supporting structure will withstand the weight of roofing, heat insulation and other materials.

non-flat roofs with insulation (pitched, roof) technology is another.
insulated slope, it is necessary to make the air space between the insulation material and roofing.It is also important to have a vapor barrier designed to prevent the penetration of steam inside a residential house, as in the case of a mansard roof type.Such a layer can be installed separately, but often it is a built-in heater.

better thermal insulation layer and the easiest to stack between rafters.But you can on the rafters.In the case where the insulation installed in the finished building, then the only option is the location of insulation - the rafters.
insulated attic insulation boards are placed on inclined surfaces between the guide extending from the base to the roof ridge.

Quite often in suburban homes are present attics.In such cases, if the attic is not used as a dwelling, the roof itself is not insulated - only the floor of the attic.Otherwise, of course, also insulate roofs.And, of course, that the house was really warm, the heaters should be used not only for the roof, but at least for the walls and windows.

Protect your home from unwanted moisture allows the waterproofing of the roof.Materials for this kind of protection as in today's market there are many.One of the most common is mastic, which is perfect for flat roofs.Mastic is applied directly to the roof surface in the form zhidkovyazkom thus formed waterproofing membrane.Polyurethane - one example of a protection mastic.

One of the cheapest and easiest ways to insulate the roof from moisture is sticking roofing felt, polyester, fiberglass and other materials of the same series.Today this method is considered obsolete, but still often used.

also used for waterproofing special film in the form of a laminated polypropylene fabric, malopodverzhennoy tearing and stretching.This waterproofing is secured under the roof covering.

Perfect waterproofing that does not require additional materials to provide certain types of tile.For example, a flexible shingles or cement and sand.And over time, their waterproofing properties are amplified.At the same ceramic tiles, they are reduced.

Another common type of moisture protection is to secure to the roof by means of screws or welding sheets of plastic or metal.Especially popular in the first case vinilplastik and plasticized in the second - stainless steel, copper and aluminum.

Of course, the list given here hydro and thermal insulation materials is not complete.Therefore, the repair or construction of the roof is always better to get a detailed consultation with experts to protect the premises from excessive moisture and heat loss.
