Netted wall fill: specified containment, required checks and the board handover
A townhouse board crew reports that filled netting projects beyond the framing in two walls. The insulation team proposes rolling the faces flat, but the actual containment method and effects on required fill have not been reviewed.
Treat the netting as part of a specified application method, with its own fixing, filling and finishing requirements. Greenfiber’s current guide illustrates product-specific containment details intended to manage fill and boarding interference. Do not substitute a universal staple pattern, tension or rolling method. Check the actual system and retain required density and other assembly functions while preparing the wall face for its next trade.
Agree the containment and receiving method at a first area
- Identify the specified containment. Confirm the actual fabric, netting or membrane and its role in the assembly. Locate the manufacturer’s permitted fixing, support and opening details for the framing present. Keep an insulation-containment function separate from any required air or vapour-control function. Similar-looking white sheets do not establish equivalent properties or authorize changing a specified membrane.
- Prepare and check a suitable first area. Arrange qualified installation, safe access and required service readiness. Follow the actual containment and cavity method, then verify its support and receiving condition before filling. Refer framing or obstructions outside the method’s scope instead of forcing a generic detail to fit. Record the accepted first-area arrangement so subsequent crews use a received reference rather than a verbal preference.
- Retain filling and verification requirements. Use the applicable product method and required density checks with their competent responsibility. Locate changed or separate compartments and keep their actual evidence. A bulge is a condition to assess, not automatic proof of good density. Any finishing adjustment must follow the permitted method and preserve the required installation; do not compress, roll or remove fill merely until board appears able to fit.
- Complete openings and the received handover. Repair fill openings and any affected separate layers under their actual requirements. Record the required face, density and interface checks, including unresolved areas. Agree who receives each wall for boarding and how later disturbance is referred. A clean flat appearance is useful evidence of one condition, but it cannot certify every hidden cavity or replace the area’s required acceptance checks.
Common mistakes
- Treating every sheet as the same containment or control layer.
- Calling a bulge proof of correct density.
- Flattening the face without checking retained fill.
- Boarding over unrecorded or unrepaired openings.
Checklist
The netted-wall handover retains
- Specified containment and its actual assembly role.
- Permitted fixing and cavity method for the framing.
- Received first-area arrangement and required density evidence.
- Authorized finishing and restored openings or layers.
- Located board-ready areas and unresolved limits.
Check your understanding
The wall looks flat after an improvised rolling pass. Is it ready for board?
