How to choose a brick for stoves?

Despite all the successes in the use of various technologies in recent years, the homes of many of our compatriots continue to be heated with the help of anachronistic furnaces. However, the reliability and unpretentiousness of this type of heating is still not equal, but because this approach in many cases is fully justified. When building a furnace, do not forget that the temperature in the furnace can reach 800 degrees Celsius.

Therefore, it is not necessary to use ordinary brick for masonry: for furnaces, it fits poorly. Chamotte or refractory varieties are often used. Such a brick is made from a particularly dense red clay, it is fired in a special mode, and therefore by the degree of resistance to aggressive environmental conditions it far exceeds the standard production.

When stacking the oven, pay attention also to the frost resistance of the material you are using. Ironically, brick for furnaces should have this quality to the fullest. This is especially true when the oven is in a room that is heated only from time to time. That is why in dacha seasonal houses it is best to lay stoves and fireplaces made of fireclay bricks. It is not only highly refractory, but also practically does not crack even under the influence of significant temperature fluctuations.

Among other things, it is distinguished by a beautiful straw-yellow color: such brick furnaces, photos of which can be seen in the article, are ideal for almost any interior and decoration of a house. It should be noted that when coating them with a special lacquer, which is also abundantly represented by industry, you can get a truly magical beauty look.

In the modern construction market, the refractory brick for furnaces (the price of which is quite high) is presented in a fairly wide range, but the breadth of choice should not put you at a dead end. Choose the most used and often used brands: ША-5 and ША-8, which will cover the needs of the average stove in almost all cases. If we talk about the differences between these two species, they are small: just ShA-8 can withstand a temperature of 50 degrees Celsius more, which in most cases does not matter.

In addition, fireclay bricks for furnaces are much larger than their standard "colleague" in size, which greatly facilitates the masonry process itself, greatly accelerating it. Actually this is also because the price of this type of material often bites. Very important is the geometric accuracy of the kiln brick. Any stove knows how important it is to observe the proportions and perfect evenness of the seams by laying out a fireplace or stove.

The second important factor is the highest quality of the mortar. In particular, the laying should be carried out with a joint thickness of not more than five millimeters, so negligent work here is unacceptable. Most often brick for furnaces is put on clay mortar, in which cement or a fireclay mixture is added. We recommend the use of cement GC-40 or GC-50, the technical characteristics of which are most suitable for such purposes.
