California, Arizona, New Mexico, and Colorado fire agencies have dramatically expanded the wildland-urban interface (WUI) designation over the past decade. For property owners in these zones, the threat includes ember cast from fires miles away that ignites structures through vents, roof assemblies, and window gaps.
How Shrink Wrap Reduces Ember Intrusion Risk
A properly installed shrink wrap enclosure seals roof vents, soffit openings, and under-eave gaps, which are the primary ember intrusion points identified in post-fire forensic studies. It is not a permanent barrier, but as a temporary pre-fire mitigation measure it significantly reduces ignition points.
Post-Fire Re-Entry Protection
After a fire event, structures that sustained roof or window damage in WUI areas often cannot be immediately repaired due to access restrictions. Shrink wrap enclosures protect the structure from weather while repair crews and supply chains catch up.
