Thermal insulation of the chimney - why do you need ?

wall chimneys - for what it's all done?

Often, especially in the harsh climatic conditions, there is a rapid destruction of the chimney, which in turn leads to costly repairs.Sometimes this is due to condensation, due to the temperature difference on the surface of the pipe and the surrounding air, so that during the cooling of the flue condensate impregnated his entire wall, which is especially dangerous if the outside of the chimney negative temperature.Thermal insulation of the chimney just serves to avoid this process.

insulate brick chimney can be a simple plastering on the reinforcing mesh, but is much more effective to do it with the help of mineral wool and plastering, and would be correct to use the mineral insulation, followed by various types of shelter siding, metal sheets and similar materials.The same pattern is made warming chimney.

Insulation of chimneys - tools and training

Insulation of chimneys require a set of the following tools and materials: tape measure, hammer, screwdriver, angle grinder (Bulgarian) with cutting wheel, metal scissors, a knife for cutting insulation, metal profile for wall mounting drywall, dowel-nails, mineral heat-insulation, vapor barrier film.Also, before starting work, it is necessary to thoroughly clean the surface of the chimney.

To produce insulation brick chimney, you first need to make crate of metal sheets.First, we set the guide profiles by fixing them with the help of the dowel-nails in the wall of the chimney, and the bottom is also an additional fix to the roof using the screws.

vertical racks attach to the rails using a screwdriver small samorezami- "flea beetles."The distance between adjacent vertical supports should be used insulation width.The width of the metal sheets selected based on the thickness of insulation, which in turn forward, focusing on the climatic conditions and the characteristics of the insulation.

understand the intricacies

After installing battens proceed to installation of insulation .To insulation brick chimney was quality, it is necessary to look carefully to ensure that between the plates did not have slots, in order to avoid thermal bridges in operation.insulation can be cut with a special knife, if necessary.

If we have to put, for example, 100 mm insulation, and insulation thickness - 50 mm, the second layer should be laid offset to the mats at the junction of the previous layer accounted integral part of the mat further layer of insulation.

In places strong sagging insulation mats if necessary, they can be additionally attached to the wall of the chimney using dowels-umbrellas.All work with insulation of mineral wool must be made subject to the appropriate security measures, do not expose the insulation particles in the eyes and the respiratory tract.

After laying insulation close it with a vapor barrier film, and laid it in a way to prevent the ingress of moisture in the insulation on the outside, which will lead to a deterioration of its properties.You also need to watch closely, the film was placed correct side.Joints carefully sizing special tape.If you want to fasten the film to the metal sheets by using screws with wide heads.

then defined with cladding materials.They are quite a lot, but more often used metal profile with anodized or coated, which is attached to the crate with special screws with rubber gaskets.
