its name chimneys "sandwich" are required features of the deviceblocked pipe, which is a combination of the inner and outer channels sandwiched between the layer of insulation.To all those who would like to learn how to combine the sandwich pipe necessarily be familiar with their structure.
main differences chimney products from different manufacturers are associated with the technical specifications of pipe channels and a view of the material used as an insulating lining.
In most articles of this class of inner tube made of "stainless steel", while the material for the outer pipe duct are usually more expensive copper or brass.Furthermore, these designs differ in diameter within them pipes and thickness of insulation.Chimneys in different versions vary as temperature regimes and those in which the proceeds of their normal operation.
As a heater used in sandwich structures of mineral wool, which by their physical characteristics reminiscent of a well-known asbestos fiber.
Among the undoubted advantages of the sandwich-flues are as follows their remarkable properties:
- reduce the likelihood of condensation to a minimum;
- low degree of pollution chimney soot;
- increased level of fire safety;
- attractive design;
- lightweight design.
Lightweight construction chimney "sandwich" eliminates the need for a foundation base, which is another proof of its indisputable advantages.

Preparations in this situation is to protect places of passage of the chimney through the floor decks.For safe piping is used in such areas of particular structural component (the so-called "pass pipe"), the order of installation is as follows:
- pipe before installing the latter must be carefully prepared (closed from the outside layer of thermal insulation material, which is located along the walls).
- Then insulate the inner cavity of the nozzle and preparing it for installation.To this end, we first made marking places its installation in the ceiling, and then cut the desired aperture size.
- Immediately after that in the contact pipe is laid with overlapping outer insulating layer, after which he mounted pipe.
- To further dissipate heat between the pipe and the main pipe is necessary to provide a small air gap.
Assembly Diagram of the chimney sandwich
Features installation of the chimney sandwich with their hands we suggest you consider the example of the well-known to most builders dual system.
When assembling the next section of the inner tube is inserted into the already mounted portion, while the outer tubular billet simply worn on the previous one.This procedure will allow you to build the structure to protect the chimney duct from penetration of outside moisture.
To all It should be added that the installation of the chimney "sandwich" can be selected by one of accommodation options off of the roof of the plane.

When installing the chimney type we are considering a number of features necessary to consider the following plan:
- sealing the main channels is achieved by using a special sealant designed for a temperature of 100 degrees.
- For reliable fastening of all elements of design (pipe bends, tees, etc.) used a special form of collars.To secure the base of the channel chimney wall bracket using the model established by generally every two meters.
- length of the horizontal sections of the chimney design should not be more than 1 meter.
In order to allow regular cleaning of pipes from accumulated during the operation of burning chimney must be equipped with a special door opening (so-called "revision").
