Building Code Administrators and Inspectors Florida Principle and Practice Licensure Practice Exam

What is the required distance for installing markers indicating the thickness of blown-in or sprayed roof/ceiling insulation in an attic space?

1. 30 sq. ft.

2. 100 sq. ft.

3. 300 sq. ft.

4. 1000 sq. ft.

The correct answer is: 300 sq. ft.

In the context of blown-in or sprayed roof/ceiling insulation installation, the standard practice mandates specific marker placements to assist in verifying insulation thickness in attic spaces. The correct choice states that markers must be installed within a 300 square foot area. This requirement ensures that there is adequate guidance for future inspections or for any work that may be performed in the attic space, providing a clear indication of where insulation is located and how thick it is throughout the area. This guideline is crucial not only for compliance with building codes but also for energy efficiency purposes, as proper insulation thickness plays a significant role in the overall performance of a building's thermal envelope. By requiring markers at this specified distance, it helps maintain clarity during inspections and aids in future maintenance or modifications that might affect the insulation.
