HVAC
In most cases the heating, ventilation and air conditioning systems in buildings are insulated. The requirements of the insulation are generally to keep the circulating hot water or warm air at a constant temperature, or to avoid increased heat in cooling water or cold air systems, thus providing a more efficient system and preventing condensation.
In the HVAC applications, fire safety is an important factor when choosing the insulation.
A wide selection of insulation products can be used in the mechanical systems in buildings, including:
Pipe sections for heating and warm water piping
Pipe sections for cold and cooling water piping
Thermal insulations for boilers, furnaces, heat exchangers, tanks, and other heat transfer equipment
Thermal and fire insulations and sound absorption products for ventilation and air ducts
Thermal and fire insulations for chimneys and exhaust pipes
Heating and warm water piping
The extensive range of pipe section sizes covers all standard dimensions for pipes generally used as heating and water pipework. The pipe sections are easy to install and can be coated with various products as required by the application and site installation.
Ventilation machine rooms, basement corridors and exits, where pipework is usually located, are critical areas when it comes to the fire safety of a building. In such facilities, non-combustible insulation is appropriate for increasing the fire safety of the whole building.
Cold and cooling water piping
Pipe sections coated with vapour-proof mesh-reinforced aluminium laminate are suitable as condensation insulation for cold water and cooling water pipework. Besides preventing moisture damage caused by condensation, the insulation also prevents the water in the cold water pipes from warming up, thus giving a more efficient system.
Furthermore, rainwater sewers in heated facilities inside buildings require condensation insulation. To ensure that the coating is vapour sealed, the joints must be appropriately sealed using taping.
In unheated facilities, heating and water pipework must be protected against freezing by the correct insulation being applied and if required, by providing additional heating (e.g. trace heating). Furthermore, sewers in open basements or lofts must be insulated to prevent the inner surface of the ducts from freezing (additional heating may also be required).
Air ducts
According to general building standards, it is important to insulate the air conditioning ducts against heat and fire. Taking care of sound attenuation is also vital when ensuring a comfortable environment.
Thermal insulation assures the functionality of the air conditioning system and directs the right kind of air to places where it is required. Thermal insulation also reduces the total energy consumption of the building by directing heat as necessary.
Fire insulation ensures sufficient escape time in the event of fire and limits fire to certain fire cells.
Insulation is also needed to attenuate the noise from air conditioning units and flows in ducts, in order for the noise to not impair the environment.
Insulation of equipment
Energy can be saved efficiently by appropriate insulation of the core components in the heat generation and distribution systems of a building, such as heat distribution and boiler room equipment, since they combine the highest temperatures and the greatest heat releasing surfaces. Releasing the excess heat through ventilation wastes energy.
Insulation slabs and mats are suitable for insulating equipment used for heating purposes. The pre-applied facings can be advantageous and in most cases no further material is required for use in technical facilities.
Chimneys and exhaust pipes
Insulation of steel smoke ducts in boiler systems, fireplaces, sauna stoves and other such objects, function as fire insulation against other building structures as well as preventing flue gases from cooling and the condensation of corrosive moisture on the inside of smoke ducts.
In exhaust ducts of reserve power engines in buildings, temperatures may rise to several hundred degrees when in operation. The insulation of the ducts must be dimensioned to prevent the surface temperature of the insulation from exceeding +70°C in places where this could pose a potential burning risk.
Fire safety regulations dictate that the surface temperatures of insulations, which are against combustible structures, must not exceed +80°C. Depending on the circumstances, the fire authorities should monitor the insulation dimensioning.
