Rules for the arrangement of a parapet unit

[zihadhosenjm40]

In the case of pitched roofs, the parapet will be visible from below, since it is located above the eaves. The installation of a parapet made of galvanized steel or copper is carried out in order to protect the structure from the effects of wind and precipitation. As a rule, drip caps are installed on the parapet apron, which perform the function of draining water. Thanks to such devices, the parapet remains protected from moisture penetration.

In some cases, instead of metal aprons, concrete slabs are laid on the parapet made of concrete blocks and bricks.

In order to finish the parapet with finland mobile database steel, grooves and niches are cut in it. After that, the metal sheets are bent, giving them the desired profile, and their upper edges are inserted into the prepared gutters. Alternatively, the apron can be made of black roofing steel, but in this case it will need to be covered with heated drying oil on all sides. As practice shows, the device of joining the roof to the parapet in specially prepared niches makes the process more convenient and faster. Usually, one sheet of metal is not enough to organize a parapet unit. Since the parapet walls are not always perfectly flat, it is necessary to create additional overlaps to cover them with an apron. Temperature changes, as well as rain and snow, also have a detrimental effect on the fasteners. As a result, the metal apron may lag behind the wall.


Using gutters, the junction of the roof to the parapet can be made as reliable as possible, observing the following rules:

The height of the niche into which the edge of the apron is inserted must be at least 10 cm.
If a groove was made in the thickness of the parapet, then after installing the apron it must be filled with cement mortar to prevent the destruction of the entire wall due to rain.
Along the entire length of the parapet, wooden plugs treated with an antiseptic compound are fixed every meter. Triangular bars are nailed to these plugs, on which a metal apron is then laid. The sheets are laid with an overlap of at least 10 cm in the direction of the drain.
