The versatility of the corrugated board provides it with a wide range of applications: roofing, the manufacture of temporary or stationary fences, wall cladding, facades, and so on. An important advantage of using this material is simplicity and ease of installation with a minimum of tools and labor costs. Below we will consider how to attach corrugated board to the roof, walls, and also to the fence.
We prepare tools and materials
When buying corrugated board and self-tapping screws, you should simultaneously purchase the necessary components:
- ridge and end strips,
- endovu,
- strips of inner and outer corners.
If it is planned to clad the walls or facade of the building, in addition, you will need transverse joists in the form of Z-shaped metal profiles and brackets for their installation. When arranging a roof or finishing walls, you should also buy insulation, vapor barrier and waterproofing, which are placed on the crate under the profiled sheets. The insulation is fastened to the walls using anchors.
Before attaching the corrugated board to the fence or on the roof, you must invite an assistant and prepare the screwdrivers. Based on what needs the corrugated board is used for, there are some nuances of its fastening. To fix the sheets, use special self-tapping screws with tips in the form of a drill. They allow you to easily drill through steel up to 2 mm thick. The screw head is pressed with a rubber washer, which ensures reliable fixation and excludes moisture access to the attachment point.
- Self-tapping screws must be purchased with a shade of caps corresponding to the color of the polymer coating of the profiled sheets.
- The calculation of the number of self-tapping screws is made on the basis of the condition of at least 8 pieces per 1 m2 at a step of 500 mm for arranging the roof and from 6–8 pieces for fixing sheets to the fence.
- 4–5 anchors are required for fixing one sheet of thermal insulation.
Fastening the corrugated board to the roof
Usually the profiled sheets are fixed to the crate through the lower deflections of the wave with screws from 28x4.8 mm. An exception is the ridge of the roof, when the fastening is carried out through the upper wave. In this case, use long self-tapping screws.
Screws must be screwed in strictly perpendicular to the surface of the sheet without distortion.
The lathing for corrugated boarding with a thickness of up to 35 mm when arranging a roof with an angle of inclination above 15% is prepared in increments of up to 300 mm. At smaller angles of inclination, it is recommended to make the lathing solid. In this case, the overlap of the sheets must be at least 200 mm (two waves). For profiles with a thickness of more than 35 mm, the lathing spacing can be 300-500 mm. For sheets with a thickness of more than 44 mm, the lathing is prepared in increments of 500 mm. In this case, the overlay of sheets vertically is performed in one wave. The overlap must be at least 200 mm horizontally.
For small roof pitches (up to 12%), silicone sealants are commonly used to provide strength and close horizontal and vertical gaps. However, do not forget about the need for adequate ventilation.
Before fixing the corrugated board, it is necessary to treat the crate with special antiseptics to prevent the appearance of mold and mildew. As a rule, wood is impregnated no later than one day before the installation of the roof.
Laying of profiled sheets on the roof is done from the bottom rows up, towards the ridge. The first row of roofing is laid with an overlap of at least 30–50 mm to ensure the protection of the building walls from rain and melt water. Finally, watch a short video:
Fastening the corrugated board to the walls
For wall cladding with profiled sheets, you must first prepare the transverse joists. The best option in this case would be a special metal Z-shaped profile. The lags are fastened using brackets that allow you to eliminate the unevenness of the walls. Alternatively, you can use a profiled pipe with a rectangular cross section.
As a rule, facade and wall cladding is done with preliminary insulation. The thermal insulation is fastened with special anchors. Insulation sheets are mounted end-to-end, without gaps and gaps. From above, they are closed with a waterproofing film. After that, the fastening of the profiled sheets is carried out.
Wall finishing with corrugated board should be started from the end side, from bottom to top. Installation of sheets is carried out with an overlap vertically in one wave, and horizontally, the overlap is 100 mm.
Fastening the corrugated board to the fence
The quality of fastening the corrugated board to the fence is primarily determined by the correct choice of supports and logs. The best option for this may be rectangular or square pipes. Support pillars are buried to a depth of 1200–1500 mm, and then three rows of transverse logs are attached to them.
It is recommended to fix the corrugated board to the fence using special self-tapping screws through the waves adjacent to the logs. Screws should be screwed in perpendicular to the sheet surface. In this case, tilts and distortions are unacceptable.
In some cases, when it is not possible to screw in self-tapping screws from the outside, the profiled sheets are attached to the fence using special rivets for corrugated board. The diameter of the rivets is selected taking into account the sheet thickness, as a rule, 3.2–6.5 mm. The rivets are made of galvanized or special aluminum steel. Like self-tapping screws for corrugated board, rivets can be with colored caps. The sheets are riveted using a hand-held construction gun.
The calculation of the number of rivets for fastening the corrugated board to the fence is made on the basis of the condition of 6-8 pieces per 1 m2.
To ensure reliable fixation of the sheets, it is necessary to put screws or rivets at least after one wave. Otherwise, with strong gusts of wind, the corrugated board will bend, vibrate, making an unpleasant sound.
For a more aesthetic appearance, the corners and ends of the fence should be covered with corner or end strips.
