Often many owners are equipped with a half-wool roof with their own hands, which in design is something between 4 and 2-pitched roof. This roof is especially necessary if your house is «on seven winds». We will talk about its device, as well as pluses and minuses, in the article.
Advantages and disadvantages of half -wool
The initial stages of work — preparation for the construction of the structure
When designing half -wool, the following points are taken into account: the type of roof, type of climate, the need for an additional attic space. Most often, such a roof is chosen under the appropriate weather conditions. With low -snow winters, slopes are equipped with a slight angle and extensive overhangs. With snowy winters, on the contrary, it is necessary to make a steep slope and a small overhang. The main advantage and dignity of this roof is the possibility of arranging a living attic space. Also, a big advantage can be called good protection against all kinds of weather phenomena (rain, wind, snow).
Plus everything should be said that this roof has a pleasant design. The house with her looks very stately and original. The following are distinguished from the minuses. Firstly, a rather complicated rafter design. It includes many ribs, edges, sprenigs, struts, rafters and other elements. Secondly, high material expenses. If you have never done such work, it is better to entrust them with highly qualified specialists.
The device of the four -sized semi -wire roof — structural elements
Human installation and collection of the rafter system
In terms of design and device, this roof resembles a gable structure with mowed corners. In general, the device of this roof has the appearance of a “pie” and the obligatory “components” in it are: a counter -crate, a crate for rafters, roof, insulation, vapor barrier, waterproofing and decorative decoration. We will tell you more about them.
Colelite — made of wooden racks or bars, which are connected to rafters on slopes. Designed for roof installation.
Contraughter — designed to attach the crate and fixing waterproofing. It also creates a gap, thanks to which roof ventilation occurs.
Material for the roof — it is usually used by corrugated board, metal tiles, as they have small weight, low cost, differ in simplicity in installation and durability.
Waterproofing — necessary to protect the insulation material from moisture. Today, diffusion membranes are used for these purposes. Before that, roofing material was used. But due to short-lived, it was ceased to use it.
Vapor barrier — necessary to protect the warming material from moisture (from the inside). The film is usually used for these purposes foil, polyethylene, pergamine.
Insulation — is needed to maintain heat in the room. The most popular are: mineral wool, polystyrene foam, foam. In cases where these materials already have the necessary moisture — and windshield, then it is not necessary to additionally mount waterproofing.
Decorative finish — necessary to give the roof of the finished type. Often from the inside is finished with drywall or lining.
Installation of the rafter system
The main components of the designs were listed above. But here’s how the installation of the rafter system of the semi -wire roof is made? After all, as you know, it consists of many elements that are important to alternately connect with each other. At the initial stage, a drawing is made. It denotes the amount of material. Before starting to make a roof, it is important to put Mauerlat on the supporting walls or equip a reinforced concrete reinforced belt (for brick). A roofing material in two layers is applied to this aromo -pile. And on it is already mounted on the studs of the Mauerlat beam. Formation 100×150 mm, 150×150 mm is often used for this, which is pre -treated with an antiseptic.
The design provides for the presence of diagonal or tow rafters. All this should be attached with iron brackets, cuts or other fasteners.
Diagonal rafters rest on the rafters. Otherwise they are called people. Therefore, it is important to make them stronger from 50×150 mm boards. Cooked rafters are attached to the skate beam and Mauerlat. Next, the installation of the rafters of ordinary ones, which should rely on Mauerlat and the horse, are installed. Additionally, they are attached to the side with overlays or brackets. If there are large spans, then absolutely all rafters are additionally strengthened with the emphasis, struts, a sprenigel farm.
