What is the construction requirement for Batts or Blankets?

The correct answer indicates that Batts or Blankets must comply with 10-foot horizontal fire blocking wall standards. This requirement is crucial in construction as it helps prevent fire from spreading within wall cavities. These insulation materials, when installed in walls, should be part of a system that includes fire blocking to ensure safety and adherence to building codes.

Fire blocking refers to barriers placed within concealed spaces to limit the movement of smoke and fire, which is particularly important in multi-story buildings or structures where fire can spread rapidly without proper barriers. The 10-foot standard provides a measurable guideline that ensures adequate fire protection throughout the building's structure.

In contrast, the other options do not accurately reflect the main focus on fire safety or compliance standards. Stipulating a maximum length of 10 feet or restricting installation to attics does not address the broader safety regulations. Furthermore, the preservation of organic materials is not pertinent to the fire-blocking standard required for safety in insulation installation. Thus, understanding fire blocking and its requirements is essential for maintaining compliance with building codes related to insulation materials like Batts or Blankets.
