How is the installation of metal with their hands

For a start it should be clarified that the metal is a relatively new type of coating for the roof, which has a metal substrate coated with a special layer.By the way, dear readers site DIY - your irreplaceable author George for the first time I have dealt with this type of roofing material 4 years ago.It is composed of zinc and aluminum.She carefully primed and coated with the composition of the polymer material.Therefore, mounting technology provides some features that should be considered.To cover this material was durable, it is necessary in the process to comply with certain procedures.Here's what I tell you today.

order of stacking metal

No matter what metal is to be mounted (and its range is wide enough), the work begins with the installation of trusses and sheathing.It will frame the foundation, on which are stacked metal sheets.For trusses are commonly used board 10 or 15 with a thickness of 5 cm. In order to eliminate deflection of sheets (for example, under the weight of snow) between rafter joists distance do from 50 to 80 cm. It should be borne in mind that from this distance, thickness depends directlybatten boards.The thinner the board, the smaller should be the space between the rafters.

Then, a thermal insulation layer stacking.It is located between the rafter beams, filling the entire space.It is necessary to take into account all the features of the heater, which was acquired.Top

applied waterproofing layer.However, it should be a small distance, the gap (recommended within 5 cm) insulation between them.It is necessary to ensure natural ventilation, which prevents insulation from getting wet (condensate) and damage.Therefore, you need to mount additional (intermediate) crate.

waterproofing layer is applied horizontally.For better stacking it in a few places is fixed at the intermediate purlins (you can use a staple gun).waterproofing film lies "overlap", and the top edge of the strip should be, which is closer to the ridge of the roof.This will prevent water from entering the joints.When the entire layer is laid, the final fixing it is carried out using strips (kontrobreshetka).Reiki should be fixed in the joints insulation film strips.However, you can not do more crates, if used for waterproofing material well permeable vapor.

should be remembered that the sealing tape in any case can not be stretched.It should be laid freely with some "slack."Otherwise it can not withstand the load (pressure accumulated moisture).

Metal fits with the lower left corner.In this case, the following list will cover the previous one, and not "slips" under it.This method avoids scratches on the plates.Stacking sheets held strictly parallel to the eaves, with their lowered by 5 cm below.Laying is done in several ways.

can first put all the sheets of the first (bottom) row, and then lay the second horizontal row.You can do the installation on a vertical.It depends on the location of the attic windows, chimneys and so on. D. In short, how convenient for the master.

should be noted that at the corners of the roof will be a "disconnect" sheets.Therefore, when laying need to make a slight shift each sheet counterclockwise (if the installation is carried out from left to right).In operation, the need to control the line on the right edge of the sheets.

metal sheets are fastened to the furring in places the bottom of the "wave".Mounts made screws.The lower part of the roof needs to be strengthened mount.Here, it should be more frequent, as in strong winds the sheets are "lifted".In the field "docking" sheets are also necessary to make additional fastening to the sheathing.

This is only general guidelines for installation of metal.Specific methods is individual and depends primarily on the configuration of the roof.
