Facing brick is a building material used for finishing walls of new and restored buildings, paving paths, decoration of individual building elements( corners, socle).It is characterized by increased resistance to precipitation, low temperatures, ultraviolet rays. It is classified by its composition, color, texture.

Varieties
The shape of the products and surface texture affect the design of buildings or objects. There are shaped and textured appearance.
Shaped ( figured) brick is made in special shapes and can have rounded parts, the shape of a trapezoid, wedge. It is used when decorating walls around window or doorways, for laying arched crossings. The twisted shaped brick is used for the construction of original columns and pillars.
The textured view can have completely smooth polished surfaces or edges without machining( ragged planes).The most popular variety is a facade brick with rolled surfaces: it is given the texture of the stone by means of a larger protrusion of the central part and uneven transitions along the perimeter of the face. According to the photo of the texture brick, you can choose the type that is suitable for the restoration of old buildings or stylish finishing of new buildings.
Varieties in the color range
The color of the brick is determined by the addition of dyes or by the use of only clays and auxiliary substances in the production. For example, most ceramic bricks have yellow, orange, red or light brown hues. And clinker products with the addition of dyes can have a green, blue, violet color. They differ from analogues by the saturation and brightness of tones.
Varieties by type of raw material
Types of facing bricks made from different types of materials allow the use of building materials for laying out tracks, and for walling, plinth. Features of raw materials determine the characteristics of finished products. There are the following types of facade bricks:
- ceramic( made of high-purity clay without impurities);
- hyper-pressed( from limestone mixtures, produced by the non-flammable method);
- silicate( from lime and sand);
- clinker( the composition includes special clay rocks).
Clinker brick is suitable for facing buildings, paving paths or laying sidewalks, is characterized by increased strength and frost resistance( it does not break from direct contact with the ground).
Ceramic can have a smooth or fluted, rolled surface, has a yellow, red or orange hue( possibly adding dyes).
Hyperpressed has torn edges, suitable for creating a stylized finish of buildings.
Silicate stands out with affordable price, wide range of colors( from white to pink or dark blue), which received a lot of positive feedback from customers. Can have any shape( wedge shaped, trapezoidal and others).
Dimensions and weight
The most popular sizes of facing bricks:
- single( 250x120x65 mm);
- one-and-a-half( 250x120x88 mm);
- double( 250x120x138 mm).
There are also other non-standard sizes, for example, special clinker products with increased length( 528x108x37 mm).
The weight of the facing brick depends on its variety and manufacturer. Ceramic weigh from 2 to 4.1 kg, clinker - from 2 to 3.3 kg, silicate - from 3 to 4.5 kg, hyper-pressed - from 2 to 6 kg.
Technical characteristics of facing bricks
Facade bricks have the following specifications depending on the type and manufacturer:
- Frost resistance: F25-300.
- Brands M75-500.
- Water absorption: 2-16%.
- Porosity: 5-30%.
- Thermal conductivity: 0.36 to 0.9 W / m · ° C.
The clinker brick has the greatest strength, frost resistance and thermal conductivity.
Hyperpressed also has an increased coefficient of thermal conductivity( 0.9 W / m * K).
Before buying a building material, it is necessary to study the characteristics of each of these types. The main criteria should be the requirements for frost resistance and water absorption( according to the climatic conditions in which the masonry will be carried out).
To guarantee the long-term preservation of the selected brick, it is worthwhile to study video lessons from professional builders. Recommendations of experts will help you learn about the rules for mixing solutions for different types of bricks, application features and creating a unique pattern of masonry. Depending on the temperature and atmospheric influences on the material and its stability, the service life will be from 50 to 150 years.
