The main task of laying the function of parapet wall NYC is to ensure safety; this element is considered mandatory for operating roofs and any flat roofs on buildings with a height of more than 7 m. In general, the unit combines protective, enclosing, and decorative functions.
Including:
- We ensure safety when placing recreation areas, viewing and sports grounds on the roof, carrying out repair work, and moving along the surface for any other purpose.
- Protection of the outer coverings of the cake from wind loads and accidental ignition.
- They are protecting the facade from uncontrolled snow and precipitation.
- They are improving the tightness performance of a flat roof by closing the edges of the cake.
- Masking coatings (often unsightly looking), communications, and equipment.
- Installation and hiding of elements of lightning protection systems.
Parapet construction and waterproofing
The roofing carpet must be tucked into a prepared gutter to isolate moisture.
The brick structure is being erected before roofing works. When the time comes for the roofing carpet, the edge will be tucked into the groove made when laying the bricks. The roll is glued to the wall with one edge and the roof covering with the other. If the structure’s height is small, then the roofing carpet is glued up.
After installing the waterproofing material, a concrete parapet slab is placed on the parapet. But the building materials market offers an alternative a metal apron. It is durable and treated with an anti-corrosion agent. Thanks to him, the structure is protected from premature destruction under the influence of weather conditions. A metal waterproofed can be flat, single-slope, or gable.
Design features
Brick parapet wall NYC are erected mainly to lay the walls after the floor slabs have been laid. Brick parapets are mainly erected during the laying of walls, immediately after laying the floor slabs. Despite the seeming simplicity, laying the device is a rather laborious process, requiring experience, concentration, and attention.
So, when the height of the roof parapet is more than 0.5 m, grooves must be left on its inner surface – they will be needed for the further installation of the roofing carpet and the application of clamping strips.
If it is not high, the rolled carpet can be brought to the upper plane, covered with a metal apron or plates, and the seams must be sealed.
Bricklaying is carried out in the same way as laying walls with the selection of bricks, pulling the mooring. If necessary, brickwork can contain wooden or metal embedded parts.
In the case of arranging low structures on operated roofs, it is necessary to additionally make a fence, which must be continuous along the entire length. At the same time, its height, taking into account the height of the parapet, should be at least 1.2 m. outside, it is necessary to join the seams
It might be best if you had the following tools:
- A trowel (with its help, a solution is applied and selected, the bricks to be laid are adjusted with a handle);
- A pick (it is a small hammer with a sharpened striker – it is necessary for undercut and splitting bricks, not a single masonry can do without it);
- A cutting machine – a grinder with a cutting disc for working on stone (with its help, you can very accurately trim or cut off a brick);
- Plumb line;
- Building level (an indispensable accessory, especially when masonry is being carried out);
- Durable cords.
Types of parapets by shape, configuration
Let’s look at what kind of protective elements are in appearance and structure.
A simple element has no additional folds. It consists of two ramps. The photo above is an example of fixing a simple parapet wall NYC.
It is fixed in places of butt joints to prevent moisture from penetrating inside the roofing cake, the span of the fence. Available in a wide range of colors. Most popular in galvanized steel or PVC coated steel.
Difficult
The more complex structure of the parapets allows precipitation to be drained from both sides. The droppers are made so that they are bent under the visor.
This design eliminates the risk of water flowing under the structure, providing better sealing and moisture removal.
Decorative
In addition to the protective function, decorative elements give the building aesthetics and perfectly combine with the architectural picture.
The traditional design can be supplemented with forging, made in an unusual color scheme, from combined materials.
Decorative parapets are indicated in the building drawing. They are often installed on pitched roofs (to ensure a safe approach to the chimney), fences, and other buildings.
The curly type is made in the form of a railing. Balconies, loggias, observation platforms on the roofs of multi-story buildings, and industrial structures are fenced with such parapet wall NYC.
They are made of metal, combined metal, and wood. The installation should be trusted only by experienced craftsmen in compliance with all safety requirements.
Ridge
Ridge parapets have additional fastening from below top covered with a visor and two drip tips on the sides.
They have a long service life.
They are mounted on the roofs of residential buildings, industrial buildings. The main function is to protect the roofing cake from precipitation, to extend its service life.
Flat
The surface of such a parapet wall NYC is completely flat. It has drip edges on the sides, which are responsible for water drainage. The droppers are made in a rectangular shape. Flat parapet wall NYC elements are easy to install. Perfectly protect fences, external parts of the façade walls from external influences.
