Furnace brick: sizes, characteristics, description and reviews

Spreading the oven, each master mustremember that everything in this matter matters, including the quality of the material, as well as the professionalism of the stove-maker. If you want the furnace to have a good draft, and the products in the base are kept and give heat intensely, then you can not neglect even the most minor nuances, here you should also include the choice of brick. Therefore, before creating a furnace, it is necessary to understand what material is better to choose, as well as what dimensions it has to make the calculation.

Description of oven bricks

Brick oven, the dimensions of which are mentioned inarticle, can be a fireplace or ceramic. In the latter case, we are talking about products for the production of which red clay is used, such blocks are made using the technology of roasting. Among the advantages of this material is full compliance with state standards.

This brick can be used for erectionthe upper part of the chimney, where the furnace heat will not be so intense. If you are interested in fireplace bricks, then you should know that they are divided into 4 more types:

• quartz;
• basic;
• carbon;
• refractory chamotte.

Description of Species

Quartz is made of quartz chips,sandstone and some clay. The main ones are made of magnesite and lime mixture. If it is a carbon brick, it is made using the technology of pressing graphite and coke crumb.

The most common today is fireclayRefractory brick, clay is the basis of this material. When laying fireplaces and stoves, only chamotte and quartz bricks are used. Making a comparison between the first and the ceramic block, it can be noted that the stoves most often prefer chamotte products.

Reviews

Brick oven, the dimensions of which are mentioned inarticle, has many advantages and some shortcomings, which you can learn by reading the reviews. Among the pluses, consumers note the ability of the material to hold heat for a long time.

Heat transfer occurs slowly, which explainslong-term preservation of the heat of the fireclay stove. Users also note the shortcomings, which are expressed in the ability to quickly gain and retain moisture within a long time. Therefore, chamotte is not recommended for outdoor storage in the open air.

Main characteristics

Brick oven, the dimensions of which will be mentionedbelow, has two main characteristics that must be taken into account when selecting products. These include the brand of frost resistance and the brand in terms of density. These features affect the quality of the unit. Mark by density is not an indicator of low or high quality, but an indicator that allows you to get the following information: the higher the density appears, the slower the brick will heat up.

Kiln brick, the weight of which mustinterest any master, can have the following density indicators: from 100 to 500, as intermediate values ​​are: 150, 200 and 250. You should not assume that the higher the density, the more suitable the material. A certain brick block parameter will be suitable for the construction of individual objects. If you need a brick for the furnace, then you should opt for a density brand of no more than M-250. If you prefer products with a higher density, the kindling of the furnace will be a real challenge.

Why pay attention to frost resistance

When choosing a material it is important to consider not onlybrick standard kiln sizes, which will be discussed below, but also a brand of frost resistance, which allows you to get information about the ability to recoil and absorption of moisture.

This characteristic is important for products thatwill be used for the arrangement of the chimney. To carry out such work, you should choose a brick that has quite impressive frost resistance indicators.

Dimensions and weight

On sale today you can find the red stovebrick, which may have different sizes. For example, the parameters of a standard block are limited to the following indicators: 250 x 120 x 65 mm. The wedge has the same parameters as the side wedge, which, in turn, has the following dimensions: 230 x 114 x 65 x 55 mm.

If you prefer a slab, then it may have twosizes, among them: 460 x 230 x 75 or 600 x 230 x 90 mm. When choosing the size of the furnace brick for the chimney and the furnace itself, one should prefer the standard form. With the help of a side wedge, it is possible to form a figured masonry, while the end wedge is used for a narrowed butting. It will be possible to shut off the firebox with the help of a stove.

The size of the furnace brick may be different. Thus, the standard material is made slightly longer, which allows it to be used, despite the impressive mass. Allocate another one-and-a-half and double the size of a standard brick. In the second case, we are talking about products whose length is twice as long as the length of a standard brick. If you are interested in the size of the kiln red brick one and a half, then you should remember that its length is one and a half times larger than the length of a standard product.

Dimensions and characteristics of Vitebsk brick

For the reason that the masonry stovesIt is recommended to use only high-quality material that is well burned and can be processed. Attention should be paid to Vitebsk brick, which has sufficient strength.

In a wide range you can findseveral types of products of this manufacturer. For example, a ceramic kiln ordinary full-bodied single brick, the dimensions of which are 250 x 120 x 65 mm, may have strength marks of 85 or 200. As for frost resistance, the material may refer to F15, F25 or F35. The water absorption of this material is 8%, and thermal conductivity varies in the range of 0.529 W / (m • K). The mass of one product is 3.7 kg.

Dimensions of Vitebsk kiln brick vary independing on the type of product. For example, a ceramic ordinary full-bodied thick brick will have the following dimensions: 250 x 120 x 88 mm. Its water absorption varies from 13 to 14%. The mass reaches 4.8 kg, and the block is made according to GOST 530-2012. On sale you can find ceramic ordinary solid brick with chamfers. Its dimensions remain the same as in the first of the cases mentioned, as well as the mass, as well as thermal conductivity and water absorption. An ordinary full-bodied single-brick brick weighs a little less - 3.6 kg, while the thermal conductivity and water absorption remain the same as the dimensions.

Chimney dimensions

When laying a chimney it is necessary to remember thatthat its vertical dimensions will have the greatest impact on cravings. The correct chimney should not have a height of less than 5 m. Among other things, the difference in height between the surface of the roof and the head is crucial. Thus, the upper point of the pipe should be at the level of the ridge or be slightly higher with a distance of no more than 3 m. If it is a flat roof, the elevation above it should be 1 m or more. When chimneys are settled down, brick sizes must be considered. Thus, the wall thickness should be 10 cm, with regard to residential buildings.

The entire length of the brick must be laid outThus, the area of ​​the inner part of the pipe is constant. The size of the chimney also depends on the size of the building. So, if the pipe is big, and you install it on a small house, it will look ridiculous. The least brick consumption can be achieved when the pipe has internal dimensions of 260 x 130 mm. This design will work if you lay out each row of 5 bricks.

You can find pipes and more impressivesizes, it concerns Russian stoves with a large portal. In this case, it is recommended to choose a kiln brick, the dimensions of which will allow forming a channel section of 260 x 260 mm.

Conclusion

Chimneys can be laid out of full-bodiedceramic brick, whose brand is designated as M-150, it is equal to the furnace brick. It is necessary to use furnace clay solution for this, filling the seams completely. The thickness of the latter should be 10 mm or less. When the pipe is laid in the attic and above the roof, cement must be added to the ingredients of the heating solution. Experts have recently advised to use facing bricks for laying pipes over the roof, as it has a high frost resistance.
