In residential construction, insulation is installed after the rough-in of plumbing, heating, and what other system?

Insulation is typically installed after the rough-in of plumbing, heating, and electrical wiring in residential construction because it is crucial for ensuring that all hidden systems are in place before sealing up the walls. This order allows for any necessary adjustments or repairs to be made to the electrical wiring before the insulation is applied, which prevents potential damage to the insulated areas and allows for better energy efficiency.

The rough-in stage involves ensuring that all the necessary infrastructure for plumbing, heating, and electrical systems is correctly positioned and functioning before the final wall coverings, such as drywall, are installed. By installing insulation afterwards, builders can achieve optimal thermal performance in the space while safeguarding the integrity of the electrical installation. Therefore, focusing on the sequence of installation is important for both functionality and energy efficiency in residential construction.
