Why is it important to maintain clearance in baffling installations?

Maintaining clearance in baffling installations is crucial to ensure proper air circulation around heat sources. This is important because adequate air movement helps in effectively distributing heat and preventing hot spots that could lead to inefficiencies or damage to the building materials.

When air can circulate freely, it allows for more effective heating and cooling, thereby enhancing overall energy efficiency. It also helps to avoid situations where heat can accumulate excessively in confined spaces, which is particularly significant in systems involving combustion or where heat-producing appliances are present. Poor air circulation can lead to overheating, which can not only degrade the materials surrounding the source but also pose safety risks, including fire hazards.

The other factors, while relevant to building performance, do not specifically address the primary role of clearance in baffling installations as it relates to air circulation. Maintaining clearance does not directly impact material costs, insulation degradation, or thermal bridging in the same manner that it influences the ability of air to move effectively around heat sources.
