Materials for insulation

Good ventilation is needed to ensure that the room was always fresh air.After all, the fresh air is there or not, often depends on normal people.All high-rise buildings are equipped with a ventilation system in the construction process.But homes today are increasingly equipped with such systems.

In winter, warm air that comes out of the premises under the influence of negative temperature condensation forms inside the air handling units.Gradually condensate destroys not only the vent pipe, and roof.To this did not happen it is necessary to insulate the ventilation pipe.

Why should insulate the ventilation pipe

For this purpose, any materials that have good thermal conductivity.With the success

also apply materials having a surface laminated with aluminum foil.For example, the foil on the expanded foam perfectly reflects the flows of cold air.It also protects the insulation material against damage.

Modern industry produces ready-made components in the form of cylinders, half cylinders, shells, cords, which can be mounted on pipes of any diameter.

Methods

insulation Mineral wool

Before you insulate vent pipe with cotton, it is necessary to clean them from dust, dirt and rust.Then - to paint, if necessary, the pipe and wrap it in a single layer.Vata is fixed ties of cord, wire, adhesive tape and so on.Above it is desirable to lay, for example, a layer of glassine, roofing material, which is able to protect the insulation from moisture.At the completion of glue formed seams aluminum tape.
Attention!When working with mineral wool observe safety rules: do not expose the particles to the respiratory tract and the eyes.

foam and polyurethane foam (polypropylene)

material is available as a ready-made shells, but because insulation is made easy.To do this, cut a piece of the desired length and put on the pipe.After that, we can only fix the lock connection.Thermal insulation of polypropylene is produced in the same manner as the foam.

foamed polyethylene

This is the most common insulation for the ventilation pipes.This material is a ready-made shell, take the necessary form.

need for insulation:

  • measure material;
  • special seam along the cut insulation shell;
  • shell set around a pipe;
  • seam glue special glue or adhesive tape.

Warming of foamed polyethylene vent pipes are safe for health, because the material does not emit harmful substances during operation.

How to insulate the gas pipe?

In a heated tube thrust is carried out better than cold.The most popular heaters are basalt fiber, Isover, Ursa.Basalt fiber withstand temperature up to several hundred degrees.

work done mostly similar to the above methods.

Warming sewer on the street

In areas with severe winters special heaters are used.They are rolled, shaped type and (under certain pipe diameter).To insulation of sewer pipes in the street was durable, insulation before digging in the ground need to wrap a layer of waterproofing.The fact that certain materials, absorbing moisture, losing their properties.

Another method - the use of a special heating cable.But its cost is very high.In addition, it requires the provision of uninterrupted electricity revenues.
