The better insulate the roof of the attic

better insulate the roof of the attic.

If your intention is to build a loft, is already mounting truss construction house roof and installation of its coverage to take measures for its good insulation.Insulation must not only protect the attic space from precipitation, but also hinder the process of cooling the space.As studies indicate, through unheated roof of the house is lost about thirty percent of the heat, so look at how to properly insulate the attic in the apartment repair site.

If the attic is not warm at all, or to perform the work quickly and of poor quality, the cold air coming through the air vents of the roof ventilation is provided.Cold air coming in contact with hot surfaces of the construction of the attic will cause condensation process.Later condensation builds up between

the rafters in the ceiling and on the very surface of the ceiling.The presence of moisture on wooden surfaces is sure to pull in the appearance of mold and rotting of wooden structures.Thermal insulation properties of the roof is also very significantly deteriorate, resulting in an increase in cash cost of heating homes.

Based on the above facts, the only solution in this situation is a quality insulation of the attic space, designed for long-term its operation.We will understand how and what better insulate the roof of the attic of the house.

To date, the most popular ways to enhance the performance of thermal insulation of the attic insulation is its heat insulation using mineral-based and whether the wool fiber glass.Using the second option is a bit cheaper.The advantages of the attic insulation cotton wool include ease of its installation, the lack of organic matter in the composition of its fibers, its non-toxic to the human body, a high degree of fire, high thermal conductivity performance when properly installed.It is not wealth can be attributed uncomfortable laying fiberglass wool.This is due to the presence of small particles of dust in the wool of glass.Most of them hit on the mucosa eyes can cause serious damage to it, and hit on the skin can cause itching, microscopic lesions and allergic reactions.For this reason, all works related to the vitreous must be performed using the protection of bare body parts.These include rubber seals, closed type of clothing, a special kind of glasses with rubber elements on the edges.Be sure to use a gauze mask or respirator, as microscopic dust particles of glass are in the air.After finishing the work destroy clothes.From dirt dust glass washing does not help.

use of mineral wool is fraught with less danger.In addition, it has a number of advantages.These include the natural composition of its synthetic fibers composed of finely crushed rock dust, as well as the small share.Also, mineral wool has excellent water vapor permeability and low hygroscopicity.Its handling is much easier processing of cotton fiber glass.

However, its use involves its isolation from the external environment.Due to the excellent sound absorption properties of the mineral wool is widely used in the construction of the internal walls in the building.For the price of mineral wool a bit expensive cotton wool.But experts unequivocally recommended for the insulation of buildings and their insulation is mineral wool, because after the time funds spent on its purchase will be repaid at the expense of high-quality thermal insulation of the attic.Using a cotton wool does not guarantee preservation of the above properties.
