The roof of which the main destroying impact of atmospheric precipitation is the share is important part of any building: both inhabited, and uninhabited. Depends on quality of the material covering it, how warmly and it will be cozy in the house. It is possible to carry professional flooring to inexpensive and qualitative roofing materials.
Features of professional flooring
Profnaslil, professional leaf or metalprofile – the general name of the construction material representing the pro-thinned-out metal sheets. For corrosion protection they can be galvanized and from one or two parties are covered with special strong polymeric structure. Except protective function, it carries out also decorative as it is painted in different colors. The pro-thinned-out sheets make of strong steel of different thickness by method of cold rolling. The galvanized professional flooring which does not have polymeric top layer costs little relatively. It is more often used as roofing covering for farm buildings, garages, process and store buildings. The one that has polymeric covering perfectly looks on roofs of residential buildings including having the most irregular shape of roof.
All types of professional flooring have galvanized covering. The zinc layer is thicker, the metalprofile is less sensitive to aggressive influence of the external environment.
As roofing coverings apply as steel professional flooring from the ferrous metal which does not have coverings, and the metalprofile made of aluminum or copper alloy, but it is the best of all to use the special professional sheet for roofs which is subdivided into several types. He is: bent, rolling, perforated and with impressive stamping. Sheets of roofing professional flooring, unlike normal front, have at the edges, the so-called, capillary groove interfering flowing under them rain drops and snow slush, providing, thereby, reliable water-proofing.
The quality of the flashing pro-thinned-out sheet has to be such that when cutting the roofing grooves were not deformed and did not bend, only this way they will keep the functional purpose. Or on the photos of samples posted on the Internet it is difficult to determine by exterior how qualitative pro-thinned-out flooring is released by any given producer therefore when choosing it is necessary to read responses at specialized construction forums.
How to choose professional flooring for roof
Before buying professional flooring for roof of own house under construction, make necessary calculations and determine the exact sizes of all designs of roof. Ideally, length of sheets of metalprofile has to correspond to length of slope completely to cover it. If sheets are shorter, it is necessary to consider that stack them with an overlap therefore the useful and actual area of sheets – sizes different. Taking into account it, define how many sheets you will need to buy. Width of the flooring having the trapezoid form of profile is from 780 to 1200 meters, the profile of standard rectangular shape can be cut by your order for sheets of any length that it was convenient to be put on furring grid.
When choosing professional flooring check that it has been made with observance of state standard specification that has to be specified in the technical documentation. Such material more conforms to requirements of construction standards and will serve to you longer.
When choosing, pay attention to profile height – the it is higher, the sheets will have bigger rigidity therefore, the roof slope is less, the more there has to be profile height which also is in direct dependence and on its thickness. Check leaf for bend if effort insignificant, the leaf has to be bent and then take the former form, but even at big effort, it should not break, though can be bent. For roofs the set of types of metalprofile including having marking With – wall, but such profile has no capillary groove is used therefore that which brand is designated as the N – bearing, its height has to be not less than 2 cm is better to choose. This profile leaf will be more expensive, but, finally, is economically more favorable. As roofing covering also the import profile leaf with marking of RN-20 will approach, it also has capillary grooves providing water drain from under those places where sheets are laid with an overlap. As a rule, the step of furring on which such roofing covering keeps within has to be no more than 80 cm Krom of purely technical parameters, are important also esthetic, such as exterior and color of polymeric covering. At external inspection the surface of sheets has to be plain and smooth, not have cracks, roughnesses and scratches. The choice of color depends on your flavoring preferences and how harmoniously he will fit into the common architectural and landscape decisions used on your parcel. The most qualitative and reliable the covering from the delustred polyester, good indicators of durability with maintaining original form at coverings from normal polyester and plastizol is considered. As for cost, the pro-thinned-out sheets having the big thickness and protecting cover from polymers will be the most expensive. When you are able to buy professional flooring from the producer, the roof will cost to you cheaper also because to you will cut sheets of the necessary size at once and to you it is not necessary to join them with an overlap. Besides, it will be possible to order covering of any color from the producer, having picked up it to exterior of your house.
