Strainers and backfilling Kerwood^®

Kerwood^® foamed ceramics is widely used in various dry strainers and backfilling for leveling floors, thermal insulation and solving some other tasks. Kerwood^® goods are chosen for these purposes not only because of the technical characteristics, but also for reasons of economic benefit.

Possible fields of application

Kerwood^® lightweight filler is successfully used for leveling and adjusting the height of floors, as a loose thermal insulation layer for floors or ceilings (including vaulted or trapezoidal ceilings). It is allowed to use in situations with a large surface pressure assumed. Kerwood^® granules can also be used to protect pipes and cable ducts, when installing thermal accumulators, to insulate the exterior of the building, as a drainage strainer.

Advantages of Kerwood^® foamed ceramic granules

Due to the following properties, Kerwood^® foamed ceramics is the best choice for strainers, backfilling and other dry fillers.

• Mechanical strength
  Granules have excellent resistance to pressure, which is extremely important for use in filling the floors. Kerwood^® foamed ceramics impart the necessary rigidity to the surface.
• Low thermal conductivity
  The porous structure of the filler allows to effectively resist both heat losses from the room and, on the contrary, its excessive heating.
• High flowability
  The shape of the granules and their small size is a pledge that the filler will be distributed evenly, will occupy all the cavities and will achieve a perfectly flat surface.
• Moisture resistance
  Due to an intact shell, Kerwood^® granules perfectly withstand moisture.
• Safety
  The filler does not burn and does not emit harmful substances at high temperatures.
• Hygienicity
  In the Kerwood^® filler pests, microorganisms and mold do not multiply. It is also resistant to rodents.

In addition, the use of Kerwood^® filler also has direct economic benefits arising from the technical qualities of the granules.

Using Kerwood^® granules is profitable

Kerwood^® foamed ceramic microspheres can save money for the following reasons:

1. Light weight
   The necessary volume of filler will be lighter than other materials, reducing transportation costs.
2. Reduction of man-hours at work
   Work with the Kerwood^® filler is convenient, and all operations will take much less time.
3. Durability
   The foamed ceramic filler does not settle and retains all its qualities for many years.
4. Keeping the heat
   Energy savings for heating the room will be significant, since the heat-insulating qualities of the porous microspheres are extremely high.

It is also important to note a wide range of applications of the material.
