Fireproof boards are used to provide thermal insulation for stoves and fireplaces. They retain heat, preventing its loss.
The concept of refractory boards
Refractory plate serves to protect the premises from exposure to high temperatures when heating stoves, fireplaces. The principle of its operation is connected with multi-layering.
In most cases, plates are used simultaneously with a stainless steel screen. A refractory plate is glued to the surface of the wall using a special mastic. In some cases, an air pocket up to 3 cm thick is left between the wall and the stove. A stainless steel screen is installed as an outer layer adjacent to the stove.
Flame retardant materials
The refractory board can be made from various materials. These can be both well-known and proven over the years options, and made taking into account innovative discoveries. Among the variety of materials, the following can be distinguished:
- Asbestos is one of the most common materials. Remains strong when heated to a temperature of 500 degrees. It is made fromrefractory boards for fireplaces and stoves, sheets for fire protection of walls, ceilings and individual items.
- Vermiculite is a neutral insulator. Popular with buyers material. It is characterized by high fire resistance and excellent thermal protection properties. Therefore, it can be used to protect against direct fire or as a spark arrestor.
- Supersil is an innovative material. Made from silica. A layer of material with a thickness of 6 mm can withstand temperatures over a thousand degrees. It is believed that this indicator is due to the fact that for the first time this material was developed for the military. Today it is used for thermal insulation of stoves and fireplaces of all kinds.
Types of plates
Thermal insulation materials are produced in the form of slabs of various sizes. The following refractory boards for stoves and fireplaces are widely used:
- Fiber cement boards made of synthetic fibers without the use of asbestos fibers.
- Asbestos boards (cardboard) made from asbestos. Withstand mechanical stress, alkalis and temperatures of 500 degrees.
- Bas alt slabs are used to protect against temperatures over 900 degrees. Environmentally friendly.
- Minerite slabs are universal in their application. Do not burn, not exposed to moisture, bacteria, mold, impact resistant. In addition, they are a good sound insulator.
- Magnesium glass slabs made of fiberglass.
Decorative platesfrom vermiculite are distinguished by applying texture to the surface of the sheet
Refractory plate "Flamma"
Speaking of materials for fire protection, we should separately mention Flamma refractory boards. This type of material is produced strictly according to Finnish technology.
Flamma refractory board has the following advantages:
- Strength.
- Fire resistant. Belongs to the highest class of NG.
- Heat resistant. Withstand temperatures up to 150 degrees.
- Good sound insulation performance.
- Moisture resistant. Does not change its characteristics when exposed to moisture.
- Can be washed and rinsed. When using chemicals, it is recommended to treat the surface of the slab with a siloxane or other impregnation for concrete.
- Resistant to alkaline and neutral solutions, organic substances. But it is destroyed when interacting with acidic substances.
- Resistant to mold and mildew.
- Does not rot.
- Easy to install.
Flamma slabs are produced from cement with the addition of mica, limestone and cellulose fibers. The material does not emit hazardous or harmful substances, is safe for people and the environment.
They have a gray-beige color with splashes. The surface is smooth. The edges are even, not bevelled. Plate thickness 9 and 12 mm. They are mounted end-to-end.
Fireproof board will protect the room from fire and accidents. Therefore, during constructionstoves or fireplaces, be sure to consult a specialist. It will help you choose the right option for thermal insulation. In cases where the heating elements are located too close to the wall, the use of refractory materials is mandatory. Therefore, even at the planning stage, it is recommended to study the regulatory documents on this issue.
