Insulation of pitched roof - was the attic , the attic will

Insulation of pitched roof at the initial stage

Knowing how much rain falls on the roofs of houses in almost all regions of Russia, everyone involuntarily want to increase the tightness of the roof at his country house.And rightly so, because the heavy rain dripping from the ceiling, the water did not contribute to a good mood, and go out in the rain, with a good chance to earn an inflammation of the lungs, would risk a few.Therefore begin insulation pitched roof with waterproofing , which will be a reliable hedge against precipitation in your new room.And now before you stands the first choice as waterproofing films are of two types - "breathing", ie, paroprovodyaschie, and "not breathing", which means, respectively, do not let the fumes.

Given the likelihood of condensation under the waterproofing, and to avoid the appearance of dampness and mold, choose, of course, the "breathing" of the film, which, in turn, are divided into two types: diffusion and superdiffusion.The first is nothing but a regular reinforced film with numerous tiny holes through which the steam flows freely and does not leak moisture."Breathe", such films are not the best way, therefore between them and the insulation must be a certain gap, air gap, otherwise they will lose their intrinsic properties.Superdiffuzionnaya more perfect in this respect, as are the membranes and well passed steam, completely preventing the penetration of moisture, without any discounts on inappropriate conditions for the task.

It is worth to mention the "not breathing" waterproofing films that require additional ventilation, for at least two gaps of 8 to 10 centimeters.In these films has its advantages, in particular, against condensation, which are due to a special coating the inner surface does not allow drops down to insulation.As a result, condensate dries safely without causing dampness.Generally "non-breathing" film typically made of polyethylene or polypropylene, as well as "breathable" diffuznionnye and the membranes are typically made of synthetic fibers and nonwoven web are.Any waterproofing film is a first line of defense of our insulation and is attached directly to the sheathing and rafters being pristrelennoy to the last with the help of construction stapler.

Warming pent roof - saving on insulation

In fact, the roof must not only prevent the penetration in the attic cold winter, but also to protect from the summer heat, which, given the roof heat in the sun, afford not to everyoneinsulating materials.It is best to carry out insulation wooden roof of basaltic mineral wool, which, unlike glass, more secure during installation and can withstand higher temperatures.Better yet, use, of course, silicate fiber insulation or even on the basis of vegetable raw materials, but the mineral wool may be preferable because of its stiffness, which is important for a material disposable obliquely between the rafters. excellent substitute for mineral wool can be expanded polystyrene, also known as foam .This in itself pent roof insulation will have enough economical, as the wall on which are the rafters, implies adequate protection from the cold.However, the attic insulation foam to a greater extent to increase savings.

So, where to put a heater, has been said, however, is too broadly, so refined.Rafters in a wooden house is the main supporting element for roofing, insulation and pent roof, as, indeed, and a gable, is best done with their direct participation.Filling the space between the rafters insulation, you first of all, can work in stages, and secondly, the rafters will provide excellent thermal insulation material fixing elements.The thickness of the insulation must be equivalent to the height of the rafters, but ideally it is desirable that it reached 200 millimeters.If the rafters are not high enough, after the installation of a vapor barrier on them, you can fill the horizontal bars across the rafters with some gaps between them lay another layer of insulation, vapor barrier and then put back.

Warming gable roof - protection from fumes from

premises As already mentioned, in our thermal insulation cake is present at least one layer of a vapor barrier, which is to prevent the penetration of moisture inside the premises, often appearing in the form of vapor.Especially because we have a loft located above the other living rooms, and steam convection by law, it is always striving upwards, hence the humidity on the second floor will be higher than on the ground.This raises the risk of dampness insulation on the inside, that is, from the property.To avoid this, vapor barrier materials and are used, on the basis of polypropylene and polyethylene.The latter is not sufficiently strong, reinforced with strips of the same material and reinforced lamination.

main property of a vapor barrier - the density, the higher it is, the more reliable the material against vapor resistance.

density is important for another reason: if it so happens that the heater suddenly lose its stiffness and lose shape, it will no longer be held between the rafters and all its weight will be on the vapor barrier.This load the material must withstand without damage to itself, or gable roof insulation (or pent) will cease to be.Of course, on top of a vapor material finishing panels, for example, gypsum board is usually laid, which is being plastered, also good enough prevent a couple, but extra rigidity "roofing pie" does not hurt to give.

thickness of insulation is rarely corresponds to the height of the rafters, but to strive for the ideal is never out of place, especially the thicker the insulation, the lower the ceiling of the attic.
