If you want your house was not only beautiful, but dry and warm, with particular attention during its construction the correct device node so important: the ceiling, the roof.And we, for our part, will help you figure it out.
final stage of construction of the carcass of any building is the installation of a roof.From competent selection of materials and their proper installation, degree of protection depends on the whole house of weather conditions.
Roofing - a common concept, it includes several types of works on the device and installation of roofs, drainage systems, as well as the insulation of the ceiling and roof.
roof structure is often compared with puff pie - it consists of many elements, arranged in a specific sequence, where each layer performs its function (see photo above).
The choice of building materials for the roof is made based on the climatic conditions of the construction site, the destination of the
Roofs can be divided into several types.
- depending on the roof structure is changing and the technology of the work.The flat roof is most often used polymeric membrane or roll facing materials - they are ideal for this type of roof.
- compound sheets of web material between them is achieved by a jet of hot air welding.This applies special postmark, securely fixing roofing carpet, and allow it to achieve a complete seal.
- as insulation in roofs such use foam, mineral wool or polystyrene.
- Since flat roofs satisfied, mainly in built-up structures, good thermal insulation of the roof, the ceiling is the key to conservation of heat in the house.After all, when there is an attic, its space is a kind of air cushion keeps the overlap against rain and cold air.
- Roofs made on the basis of bitumen roll materials are short-lived, no more than 4-5 years, due to the rotting foundations of cardboard.The cost of such a roof is low, so it is most often used for temporary buildings.
- in the construction of capital buildings use more durable materials on the basis of modified bitumen. technology devices such roofs is quite simple, it is quite possible to perform with his own hands, it would wish.
- Pitched roofs are of a completely different design: it creates a bias set a certain way wooden beams (rafters).They can be fastened in different ways, depending on the design of the building foundation.
- If he columnar, or between the outer walls there is an extra load bearing wall - can be used naslonnye rafters.Average of them during installation relies on the wall or a special support and the ends - on the exterior walls.
In this case, work for bending the beam, and only.
- Another way to install trusses used in buildings, which have no intermediate supports: rafters are based only on two extreme support and called the hanging.
- Installation of hanging rafters, beams act as bending and compression, so for reinforcement Connects leg rafters metal or wooden tightening , and all the elements are fastened together with nails or staples.
- Such an assembly of rafters is more economical and faster.
- In the next phase of work under construction wood sheathing.If the roof is soft, the sheets of plywood or boards stuffed closely parallel to the roof ridge.It
- continuous sheathing.Such a sheathing substantially insulates the attic, so it is used in cases where it is used as an attic room.
- In other cases, it makes lattice, from bars section of 5x5 cm, fills the rafters parallel bars at 20 cm. Next, the installation of roofing, and it begins with the installation of the waterproofing layer.
- First lay a special film, which is connected to the joints with duct tape.Next comes a layer of insulation, hide another film - waterproofing (sm.Gidroizolyatsiya ceiling - why and how to do it).
and then proceed directly to the installation of the top layer of the roof.
- If waterproofing was performed qualitatively - the roof will last a long time, without the need for repair after a rainfall or snowmelt.And also the right to work the system of natural ventilation of the roof.
There is a huge variety of roofing, their choice is determined by the slope pitched roof, and of course the construction budget.
- roof with a slight slope in the range of 9-12 degrees most frequently covered profiled decking, slate, different types of tiles - it all depends on customer preference.
Types of roofing materials
- often used ordinary galvanized steel sheets which are bonded on special equipment in a double or single folds.This coating is called - rebated.
price far below this roof tile, which is one of its virtues.
Technology laying corrugated metal or less time consuming, just sheets are attached with screws to the crate.
quite differently work with bitumen roof shingles.
She laid on a layer of bitumen mastic overlapping, on a carefully cleaned and dried the base, or fastened with nails.
There are options such tiles having lower self-adhesive layer. All varieties of slate assembled by the same scheme - in sheets in advance drilled holes for the nails with a special anti-corrosion hat, fitted with a rubber gasket and put them on the crate.
on the Web site has more detailed instructions and even videos on the subject.
important component of roofing is the organization of drainage systems.When installing pitched roofs used external system consisting of gutters and pipes, both metal and PVC.
Plastic pipes is much cheaper, but under the influence of temperature changes can be deformed, resulting in protёkam.There are special seals are included such systems.
They allow you to extend the life of pipes PVH.No they can not match the durability of metal pipes, especially copper, which can serve for many decades.
The flat roofs of the water flow provide internal.They included the pipe, a funnel for draining and connection elements.
When designing the drainage system of the building, takes into account many factors: the roof area, slope, especially climate regiona.Gramotno organized flow of water not only protects the base and walls of the building from destruction under the influence of moisture, but also gives the building attractive and finished look.
Warming attic floor
Even with a loft and a good waterproofing of the roof, overlapping the last floor must be insulated.Then the ceiling will always be dry and indoor dampness appears.
cottages with beamed ceiling, for example, for this purpose use mineral wool or fiberglass boards.Lay them on a prefabricated vapor barrier.
It may be an ordinary polyethylene film.This vapor barrier film to protect the insulation from moisture.
There are insulation materials with vapor barrier finished.One side of this mineral plate lined with foil.Shiny side down and put the heater.
capital in homes where the supporting structure - a hollow-core slab, the device is a vapor barrier is not necessary because the concrete has a low water vapor permeability.
Here the most important thing - to calculate the thickness uteplitelya.Krome mineral wool as insulation, you can use other materials: polystyrene, expanded clay, and even sawdust.
We hope that helped you correctly orient in a sea of information and do in your home nice and warm roof.
