Air sealing the building envelope is a critical component of effective energy efficiency in commercial and residential buildings. It is the process of preventing air leakage, which can lead to uncomfortable living or working conditions, higher energy bills, and moisture damage. A properly sealed building envelope will save money on heating and cooling costs by reducing drafts, maintaining consistent temperatures indoors, and preventing outside air from entering the structure.
The benefits of air sealing go beyond improved energy efficiency; it also leads to improved indoor air quality by blocking pollutants such as dusts and gases from entering the building through leakage paths. Additionally, it reduces condensation problems since moisture is prevented from seeping into walls due to an effective seal.
In short, air sealing has a wide range of benefits including lower energy bills, reduced drafts, more comfortable living/working conditions, improved indoor air quality and less condensation issues. To ensure maximum benefit from proper air sealing of your building envelope in terms of performance and longevity speak to an experienced contractor who can evaluate your home’s needs accurately & design a plan accordingly.
Air sealing starts with inspecting the walls, roof, windows and doors for any gaps or cracks that can allow air to leak in or out. Gaps around window frames, door frames, penetrations for wires/pipes and other places need to be sealed properly using caulks or weatherstrips. In addition to these measures, installing insulation materials in walls and attic helps to maintain the temperature inside the building by trapping heat during cold months and blocking heat during hot months.
