Can PF Foam be injected into an existing wall for insulation or soundproofing?

It depends. The quick cure PF Kits expands with a lot of force and since the installer cannot see how much foam is injected the expanded foam can “blow out” the wall. It is recommended that foam be applied from the bottom up. “Breather holes” every 6″ are recommended to reduce foam pressure. Disclaimer: Rivenco Industries Limited has not done any testing to determine suitability of PF Kits for this application and cannot guarantee results. Use a PF Kit at your own risk.
