INSULATED AIR DUCTS
Ventilation ducts are generally among the basic parts of ventilation in residences or buildings with large numbers of people such as shopping malls, hospitals, hotels. The ventilation system consists of components such as ventilation ducts, fans, and ensures that the indoor air is kept in ideal conditions in terms of both heat and hygiene. For this reason, ventilation is of great importance, especially when considering commercial buildings.
Ventilation Duct Insulation
Insulation can also be done for air ducts in ventilation systems that ensure that the air inside the buildings is in ideal conditions. Thanks to the insulation, which offers the advantage of much more comfortable use in terms of both sound and heat, the indoor air is always kept clean, while the environment itself is purified from ventilation noise.
The insulation of the air ducts differs according to the length, diameter and field of activity of the air ducts. It may not be possible for every air duct to be suitable for insulation. For this reason, when choosing an air duct, it should be considered whether it is suitable for insulation or not. Otherwise, the planned isolation may cause a negative effect on the ventilation system. However, a good isolation is achieved by coating the outer surfaces of the ventilation ducts in very general terms.
What are the Features of Ventilation Duct Insulation?
Thanks to the insulation of the ventilation ducts, the indoor air will be purified from dirt, dust and microbes that are too small to be seen with the naked eye, while it will be possible to reduce the sound caused by the air flow in the ducts.
It not only insulates the sound but also contributes in terms of heat insulation. In order for the air ducts to perform the required activity and to be used for a long time, it is prevented from being damaged due to heat and reducing the service life.
WHAT ARE THE TYPES OF VENTILATION INSULATION?
It is possible to make both sound and heat insulation. The noisy operation of the fans in the ducts and the noise caused by the air flow can be a problem especially for closed areas where events such as concerts, theaters and cinemas are held.
Heat insulation, on the other hand, can cause much more damage to the ventilation ducts, especially in hot weather. For this reason, thermal insulation can protect ventilation ducts from excessive heat.
WHAT ARE THE MATERIALS USED IN DUCT ISOLATION?
The materials to be used during duct insulation may be different from each other.
Polyurethane: It is an insulation material in the form of foam that is preferred to create thermal insulation. When applied to sun-exposed areas, it is painted with protective paint.
Glass Wool: It is produced in the form of mattresses, sheets or pipes and is used in a temperature range of –50 to +250 degrees. It functions as heat and sound insulation. In addition, it helps acoustic regulation and provides a safety against fire. (The application must be done in the field.)
Stone Wool: It is used for heat and sound insulation. The part consisting of aluminum foil comes to the outer surface and is fixed with tapes so that it does not leak air. (The application must be done in the field.)
Rubber Sheets: The raw material of the material produced flat is also rubber. It must be applied in such a way that there is no gap between the material and the duct, and it must be adhered to prevent the risk of leakage.
What are the Criteria to Be Considered in Choosing Insulation Material?
When choosing insulation material, it will be useful to consider the following criteria:
IN WHICH AREAS AIR CONDITIONING DUCT ISOLATION (HVAC) MADE?
It can be applied to the ventilation channels in the buildings where the ventilation system is located. There are applications in many areas, especially in shopping malls, markets, cinemas, theaters, opera halls, cafes and restaurants, business centers, hospitals and residences. Moreover, it has many benefits:
