There are several different types of mansard roofing systems, namely:
- Triangular.
- Asymmetric.
- Symmetric.
- Broken.
One of the most important motions of the design is the calculation of the angles of the inclination of the roof of the roof. When performing this stage, the following features should be taken into account:
- Climatic conditions of the region.
- The appearance and characteristics of materials used for construction and finishing.
- Personal preferences of the owner of the house.
Mounting nodes of the rafter system.
The bigger the angle of inclination of the roof of the roof, the smaller there will be free space in the attic room. However, if the angle is too small, the roofing system will be more difficult to cleanse from precipitation and pollution. After a while, this will lead to a decrease in the reliability of the system. Therefore, it is very important to choose the optimal roofing material for the existing conditions.
The installation of the rafter for the roof of the attic ensures the strength and stability of the roof. When performing this work, you need to comply with a number of rules. First, the design is constructed from wooden beams with a cross section of 100x100 mm or 150x150 mm. Secondly, the system is carefully indoilable. Usually rubberoids or only use as waterproofing.
The frame design is placed on the base from reinforced concrete. Wire and metal brackets are used to attach the carrier node. Quite often applies spike-grooves. It is important that the wood that is used for the construction of rafters had no more than 15% humidity. If possible, the choice should be given in favor of coniferous rocks.
Be sure to be created a disinfectant atmosphere. Remained bars are strictly forbidden to use. Because of them, the entire rafting system can simply collapse. Therefore, before applying, the bars must be dried. Additionally, wood is impregnated with antiseptic and anti-footage.
Performing the installation markup of the supports, calculate the installation step so that all the rafters are installed vertically in the same plane. Check the verticality of the installation will help you with a friend to any builder called a plumb.
To fix parts to be the most reliable, use the offset or stretching. Vertical racks up to suitable materials. Most often double-sided covering with plywood and drywall. Between the sheets of the plating must necessarily be laid insulation.

Step-by-step instructions for mounting rafters
Strengthening scheme raftered with additional subproof.
The process of mounting the rafting system for the roof of the attic begins with the laying of the top bar. To secure it, you can use nails, screws and metal brackets. Bruces are used by a cross section of 150x150 or 100x100 mm.
After that, the installation of Mauerlat is performed. It is necessary, first of all, so that the roof does not overturn over with a strong impact rush. Mauerlat must be designed and mounted in such a way as to withstand the loads that come to the roof of the house and on its walls. Directly Mauerlat is laid out from BRUSEV. It is best to use bars 100x150 mm. You can also apply boards with a thickness of 50 mm.
The selected material should be put horizontally, after calculating the size of the surface of the walls. Under each bar or board, the waterproofing material is mounted, which will protect the elements of Maurolat from the harmful effects of moisture.
At end, the rafting legs are mounted. These design elements can be purchased at the finished form or do it yourself. First, the step of the rafter feet is calculated, after which the markup is applied to Mauerlat. To do this, you need to put marks on the ram and Maurylalat. Professionals are recommended to mount rafters in a step of 1-1.2 m. Lay out the extreme rafters to the front. It is important that the line of edge of the front and the top of the legs were on the same level.
The rafters are made from bars or boards. It is important that the boards are straight.
From using the material with bitch it is better to refrain, the maximum allowable amount of bitch - 3 pieces per meter.
