"Air" roof: the roof of the house need to breathe
Bashny.Net
The roof of the house need to breathe, and without a proper ventilation system service life is significantly reduced. Ignorant man it is hard to imagine why you need ventilation if the roof is made of quality material, and where, he says, to take moisture?.. Today, many do not set the ventilation system the roof space in their homes, and this is a big mistake. Especially during the installation of metal roofs and sheeting.
Both these materials have a so-called dew point, which is on their inner side. Between the sheets of metal roofing and waterproof film accumulate in the condensate. In the absence of ventilation formed in the roof space, condensation may cause rotting of wooden structures, destruction of crates and kontrobreshetki, which is attached to the roofing material.
Further — more. Due to the high humidity in the roof space insulation gets wet, the efficiency decreases significantly, a wooden structure begin to rot, moisture gets into the dwelling.
Ventilation of roof space is required the classic mansard roofs when the roof is warm room, not cold attic.
Attics not used as living and therefore do not need heating. Air circulation in these areas occurs naturally when air currents pass freely through openings in the eaves, the roof ridge and gable grilles on the facades. Natural air circulation is beneficial to the wooden rafters, which, thanks to this ventilation become stronger and last longer.
Quite differently arranged attic (insulated) roof. The warm air inside the home resulting from human activity, the laws of physics strives up. Due to the temperature difference between indoor and outdoor air, especially in the cold season, the room appears condensate, which we discussed above. The under-roof space or ventilated gap called the space between the roofing material and waterproof tape.
What happens in the absence of a ventilated gap? Wooden rafters and insulation materials are constantly exposed to condensation or rain from the outside. In winter warm air is not cooled in the roof space heats the roof and causes the melting of snow, formation of ice and icicles. This leads to the destruction of the roof and gutters.
By the way, poorly assembled or nonexistent air gap leads to negative consequences very quickly — after six months on the walls of the house can appear dark stains and spots.
For the proper organization of the under-roof ventilation is necessary to release the accumulated in the roof space air mass and moisture and provide the fresh outdoor air. To do this, in the lower part of the roof made produhi through which outdoor air enters the roof space and pushes through vents in the ridge area of the roof moist air.
Vents or roofing aerators (agroalimenta) are of two types: spot and continuous. In the first case, the aerators installed at some distance from each other and rise above the roof.
Continuous aerators are mounted across the length of the ridge, they are invisible: first, because they do not protrude above the surface of the roof, second, painted in the color of the roof.
Consider the algorithm of the ventilation outlet on the roof of metal.
— The number of ventilation outlets — one per 60 sqm of the surface of the roof.
— When you have a complex roof structure, the number of ventilation outlets should increase.
— Vent must be no more than 60 cm from the ridge.
— The hole for the vent is marked using the template included in the package.
End part of the metal holes must be painted to avoid corrosion of the hearth.
Ventilation passageway is fixed to the roof using a rubber ring, fixed with silicone, and optionally, special screws, also included in the package.
Waterproofing and vapor barrier film should have a tight and plumb to the vent pipe with the roof; so that moisture did not get into the sealing layer, it is necessary to apply additional silicone sealant.
The device under-roof ventilation is the case when the entire work should be left to professionals. Only qualified personnel, observing all the technological canons installation of roof ventilation, will create proper roof ventilation in your home. published
