A professional insulation contractor will typically begin by assessing the structure to determine the areas that need insulation and the best type of spray foam to use. Preparation: Before applying the spray foam, the area to be insulated is prepared by cleaning and, if necessary, sealing any gaps or cracks.
The spray foam insulation is applied using specialized equipment that mixes two chemical components, polyol resin, and isocyanate, at the point of application. These chemicals react to create the foam, which expands to fill the space and then hardens within minutes.
After application, the foam undergoes a curing process, during which it expands fully and hardens to create a durable insulation layer.
Once the foam has cured, any excess material is trimmed away, and the surface is finished as needed.
