Is it true that sealing and insulating homes will make them more energy efficient and can keep out most pollutants?

The assertion that sealing and insulating homes can enhance energy efficiency and impede most pollutants is generally true. When homes are properly sealed and insulated, they create a barrier that can significantly reduce energy loss, leading to more efficient heating and cooling systems. This improved insulation also helps mitigate the infiltration of outdoor pollutants, leading to better indoor air quality.

While some might believe sealing and insulating should only apply to new homes, existing homes can also greatly benefit from these improvements. Additionally, the effectiveness of sealing and insulating is not limited to specific materials; various insulation types can achieve energy efficiency gains.

Therefore, the idea that sealing and insulating do not contribute to energy efficiency and pollutant exclusion is not accurate. Such improvements are beneficial regardless of the age of the home or the materials used, reinforcing the value of these practices in promoting energy conservation and healthier living environments.
