What are the advantages of using open-cell spray foam?

ypically, buildings expand and contract due to temperature differentials, moisture content, wind load and seismic etc. Closed-cell insulation cannot accommodate the movement of the building. Open-cell spray foam provides air sealing benefits in many applications at lower costVapor permeability supports bi-directional drying of assemblies, critical in warm climate zones/seasons Flexibility allows it to expand and contract with any movement of the building structure ensuring long term air sealing Water-blown product maintains a lower GWP (GWP 1) than most closed-cell products
