Sound insulation is mostly associated with the importance of improving the energy efficiency and regulating indoor temperature. However, it also has a profound influence on IAQ, and this aspect plays a critical role in the occupants’ health. This is how thermal insulation affects IAQ and why it became the essential factor in the construction of buildings and their maintenance. Temperature control therefore increases the efficiency of the ventilation systems by providing adequate fresh air to the rooms and at the same time, reducing indoor polluting agents.
Another facet of indoor air quality, which is affected by thermal insulation, is humidity. On the same note, insulation installed correctly assists in controlling high humidity levels within homes as it does not allow for formation of dampness on walls and ceilings.
Water seepage can cause mold and mildew formation, leading to the emission of spores and mycotoxins which are hazardous to human health because they cause allergenic and respirational disorders like asthma. Since thermal insulation helps to minimize the formation of moisture then it helps to reduce the incidence of mold and mildew hence promoting healthier indoor air.
Reduction of Outdoor Pollutants
Thermal insulation has the effect of protecting the occupants of the house from outdoor contaminants including dust, pollens and automobile exhaust fumes amongst others. Water seepage can cause mold and mildew formation, leading to the emission of spores and mycotoxins which are hazardous to human health because they cause allergenic and respirational disorders like asthma.These contaminants cannot penetrate well-sealed insulation and therefore their concentration indoors is enhanced by correct insulation.
This is especially useful in regions that are characterized by polluted air like cities that we see today. Indoor air quality is also conserved and made healthier through the prevention of contaminated outdoor air from entering through the structures that are thermally insulated.
Mitigation of Indoor Pollutants
Insulation can also have an element of applying indoor pollutants as well as well as total enclosed space requirements for air exchange. Some of them for instance the formaldehyde-free fiberglass or cellulose, have very low levels of VOCs emissions. Thermal insulation has the effect of protecting the occupants of the house from outdoor contaminants including dust, pollens and automobile exhaust fumes amongst others. VOCs are toxic compounds that can evaporate out of certain types of materials and create indoor air pollution leading to health problems such as; headaches, nausea, eye, nose, and throat irritation. The selection of insulation materials with low emission of VOCs assists in lowering the possibility of these chemicals in the indoor air.
Thermal insulation enables the occupants to create warmer temperatures in the house in cold weather or cooler temperatures in hot weather and also regulate humidity.
Temperature Regulation and Ventilation
Good thermal insulation enables interior temperature to be well regulated, hence fewer fluctuations and hence less heating and cooling is required. This can also enhance the regulation of temperature which is fundamental to enhancing the IAQ since it can lead to proper airing of the rooms. Some of them for instance the formaldehyde-free fiberglass or cellulose, have very low levels of VOCs emissions.
Electrical appliances like the heater and the cooler that seem to be always on might lead to inadequacy of air circulation, hence the pollutants stay within the room. Temperature control therefore increases the efficiency of the ventilation systems by providing adequate fresh air to the rooms and at the same time, reducing indoor polluting agents.
Prevention of Air Leakage
Infiltration of fresh air into the living space brings along with it airborne pollutants and irritants. Vaporization prevents air-tightness or the closing of voids in the insulation layer to make sure that air from inside or outside the building cannot pass though the insulation layer.

Water seepage can cause mold and mildew formation, leading to the emission of spores and mycotoxins which are hazardous to human health because they cause allergenic and respirational disorders like asthma.
Such sealing effect has a positive effect on energy performance as well as IAQ because it prevents pollutants from entering the interior while the environment is maintained at a steady condition.
Enhanced Comfort and Health
Comfort and health is directly influenced by IAQ and therefore, it is of corner importance to maintain a good status. Vaporization prevents air-tightness or the closing of voids in the insulation layer to make sure that air from inside or outside the building cannot pass though the insulation layer. Thermal insulation enables the occupants to create warmer temperatures in the house in cold weather or cooler temperatures in hot weather and also regulate humidity. This makes the chances of developing respiratory illnesses, allergies, and other diseases that threaten people due to bad quality air low. This is how thermal insulation affects IAQ and why it became the essential factor in the construction of buildings and their maintenance.
