The popularity of ondulin forces many builders to look for the solution of the question connected with the correct mounting of this roofing material as the instruction to it is very not informative.
Ondulin resembles asbestos-cement slate superficially, however its operating ability considerably exceeds those characteristics which were possessed by his predecessor.
Preparation for mounting
Mounting of ondulinovy roof demands certain accuracy. Previously it is necessary to buy necessary material and the tool in advance and also to find the assistant as with onduliny it is much more convenient to work together.
After preparation of all necessary for performance of assembly actions, it is possible to begin the shelter of roof. At first the heater layer is put. And it is necessary to lay it equal parts that overlapping of furring remained visible. Then it is possible to start laying of ondulin. Work should be begun with overlapping of the lower part of the built roof. The most optimal variant is to stack ondulin at once so that there was five-centimetric eaves overhang. When imposing sheets it is necessary to impose at least one wave on the previous leaf.
Scheme of mounting
It is necessary to fix ondulin only the special nails intended for this material. The instruction attached to ondulin demands that each sheet of material fastened in not less than two dozen nails. If to use them it is less, then under adverse conditions of climate the strong wind can break material. It is important to drive in not strongly nails, without allowing considerable deflection of leaf as then water can accumulate there. It is necessary to put after fixing in the corresponding openings caps at once that then, on the end of mounting, not to move on roof. The following ranks are put at sight which is cut lengthways. Indispensable such condition as differently laying will be not correct - water will be able to filter through joint. Overlapping of each layer makes about two dozen centimeters. After the end of mounting of sheets, begin to stack shchiptsovy material. Each shchipets gives to roof esthetic look and also protects roof from moisture penetration. For its acquisition there is no need to carry out difficult calculations - length is measured on slope of roof and completely corresponds to it. It is necessary to fix nippers just the same fixture, as well as sheets of parent material, and with step which does not exceed distance in twenty centimeters. The mounted roof will be able to please house owners with the characteristics for many years.
