Spray Foam Insulation and Coastal Flooding - Clean Up and Removal

You are here

Following an extreme weather event such as hurricane or flooding, assessment of the damage is critical in understanding how to approach the next steps. Once the extent of the damage is determined, removal can begin. It is recommended that a qualified clean-up contractor assess the removals required.

Proper cleaning, drying and disinfecting of some porous materials can take a while to complete. It is important to note that mold can thrive in as little as 48 hours in such situations so the likelihood of many porous materials requiring removal is greater. It should be a qualified remediation contractor who makes the determination as to which materials need to be removed.

Certain materials such as closed-cell spray foam insulation have been identified as flood-resistant by organizations such as FEMA. It should be noted that neither open-cell spray foam nor closed-cell spray foam will support mold growth but contaminants will.

In some cases, there may be concerns that water has migrated into interstitial spaces behind spray foam. Where plywood subflooring needs to be removed, above the closed-cell foam, additional spray foam is to be added to fill the cavity between the plywood and the foam and the contractor must assure that the air seal from below is intact. Note, all areas must be dry before this is contemplated.

Following the clean up and removal of an extreme weather event, there are important steps to consider when getting ready for retrofitting.
