TitleSpecification(s)Objective(s)
4.1301.2a
Sealing

Sealing the floor system will be completed before insulating

Ensure airtight envelope Envelope The separation between the interior and exterior environments of a building that includes a combination of air and thermal barrier

Prevent leakage

4.1301.2b
Netting, fabric

When using netting or fabric, staples will be placed according to manufacturer specifications

Netting or fabric will meet local fire codes

Secure insulation

4.1301.2c
Installation

Insulation in netted or fabric cavities will be dense packed with loose fill insulation in accordance with manufacturer specifications

Insulation will be installed to prescribed R-value

Insulation will be in continuous contact with air barrier Air barrier The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary

Insulate to prescribed R-value

Ensure a continuous thermal boundary Thermal boundary The separation between the interior and exterior environments of a building that slows heat flow between conditioned and unconditioned space
