Only that roof which does not flow is considered reliable. At the same time experts in voice claim that only the metal roof has similar characteristic. Optimal variant if it is roofed by aluminum or copper. However, only to beat sheets to the basis a little. It is necessary to connect reliably them one way or another. Today the folded joint is considered one of the best options.
In general the faltsevy roof is such basis of design of sheets of metal which are fastened on certain technology. The roof has received the name by fastening method. Today distinguish several types of fold. It is lying unary and double faltslezhachy unary (double) rabbet and also standing unary and double faltsstoyachy unary (double) rabbet. It is natural that double options it is much more reliable unary. Standing usually use for fastening of the edges going along slope. Lying put across. Special clips (pictures) located at the edges help to mount easier and quicker roof.
Features of the device of roof on folded joints
That the faltsevy roof met all requirements and standards, it is necessary to observe the instruction for its mounting very accurately. Well and, of course, to consider number of nuances. So, for example, on such technology it is possible to cover roofs with bias no more than 14 degrees.
It is possible to use such method of laying of roof and on flat roofs, it is only necessary to apply double rabbet and in addition to fasten seams with silicone sealant.
Besides, it should be taken into account that all consumables (nails, bolts, wire, etc.) which are used when laying roof by such method have to be made of steel and are covered with zinc. Otherwise they will quickly fail, and laying of roof should be made anew. Also it is necessary to work carefully waterproofing of roof and to provide normal ventilation. Otherwise under roof condensate which will lead to fast deterioration and wear of materials of roof will gather therefore it will quickly fail. It is still important to think over on what basis you will stack roof - on furring or continuous. If you choose furring, observe rated step. Otherwise all your roof will sag, sheets are deformed, and all work will need to be redone anew.
Pluses and minuses of faltsevy roof
It is natural that the faltsevy roof in spite of the fact that is optimal and ideal variant in most cases, has both number of the advantages, and shortcomings. Usually carry long life cycle, ease of design (it is not necessary to carry out additional works on strengthening of walls or overlappings), to pluses smoothness of surface because of what moisture does not linger on roof surface. And still the faltsevy roof has corrosion-resistant coating that the long time allows it to remain accurate and beautiful.
Still rather often plus call design of roof. It though idle time, but due to different fastening - standing and lying - becomes quite original.
From shortcomings, as a rule, note not especially good noise isolation of covering. That is during rain the knock of drops on steel roof is heard too distinctly and loudly. Minus also difficult mounting is considered. Still often call shortcoming unattractive exterior. But it only if the roof is made of galvanized steel. In case copper or zinc-titanium acted as basic material, the covering looks more than nobly. It is also not really good that the faltsevy roof accumulates static electrotension, and it means that it is necessary to do also the lightning rod.
Device of faltsevy roof
The Faltsevy roof is made of several types of metal. Their number includes galvanized steel (especially for roof) about 0.5 - 0.7 cm thick. Experts claim that such covering is very durable and about 30 years serve. Also polymeric materials are used. For example, steel with pokrytima. Exactly thanks to polymers, the roof receives the high and effective anticorrosion properties. Copper roofing has various relief and is decorative part of roof. For example, such copper can imitate tile. Krovelney aluminum - one more material promoting creation of the most reliable roof. Also often in production also roofing zinc-titanium - material, according to experts, almost eternal is used. Production of faltsevy roof does not take a lot of time. It is rather easily and quickly cast from metals in certain form.
Features of mounting of faltsevy roof
Mounting of roof surely begins with drawing up the corresponding drawings. Then it is necessary to make pictures for normal covering of slopes of roofs and eaves. do them of the special preparations possessing necessary forms and the sizes. At the next stage it is necessary to lift parts of roof on roof, to lay out them and to connect fold. It is necessary to attach roof also to furring bars. Special attention needs to be paid to area around pipes and flues. It is the best of all to close up them special aprons from galvanized steel. As a result you receive hi-tech roof without any openings.
