Strengthening the pipe with asbestos cement
Lining a chimney with asbestos cement requires the use of a cement-lime mixture applied to the surface of the slabs.
The flue gas duct is reinforced with mesh and the first layer of solution is sprayed on.
A new layer of the mixture is applied to the insulation sections and attached to the surface of the chimney.
Asbestos contains carcinogens that are dangerous to humans, so experts do not recommend using it in residential premises.
Sheet iron cladding
When insulating a metal pipe, the distance between the chimney and flammable materials should be maintained at 60 cm.
The structure is wrapped with 5 cm thick mineral wool with an overlap, clamped with steel wire. A metal sheet is wrapped on top.
Rivets are inserted into pre-prepared gaps, and the heads of the fasteners are closed with a special tool.
VWhen preparing the drawings, it is important to provide for a straight position of the pipe coming from the stove.
The maximum heating temperature of the outer wall of the chimney should not exceed 50 degrees.
Waterproofing a brick chimney on the uganda mobile database allows you to comply with established standards, while metal elements will require additional insulation to prevent condensation.
After installing the pipe, it is sufficient to carry out plastering followed by laying of millilite silica, MKRR-130 thermal insulation wool or MKRF-100 rolled felt.
If the outer part of the pipe is 2 meters or more high, it is reinforced with additional stretchers.
Fire protection of the chimney
Today, ready-made "sandwich" panels made of steel or ceramics are available for sale. Their installation is as follows:
To install a modular system, an asbestos gasket is placed between the stove and the chimney.
Then a layer of solution is applied onto which the module is placed. It is leveled and subsequent blocks are secured with a layer of solution.
The places where the smoke device passes through the roof are well insulated. Fire-resistant insulation of the roof will be provided by a galvanized steel box, fixed with brackets to the rafters and cross beams where the pipe passes.
Pipe waterproofing
Quick and reliable protection of the chimney from leaks is carried out by applying roll materials.
