For professionals in the construction industry, selecting the right insulation material is paramount to project success. Spray Polyurethane Foam (SPF) stands out as a versatile and high-performance option, but understanding its variations is crucial. As a leading polyurethane foam insulation manufacturer, we aim to equip you with the knowledge to make informed decisions.

SPF is broadly categorized into two main types: open-cell and closed-cell. Each offers distinct advantages suited for different applications. When you buy polyurethane spray foam insulation, considering these differences will optimize your project's thermal efficiency, moisture management, and structural integrity.

Open-Cell Polyurethane Foam:

  • This type is characterized by its soft, flexible, and spongy texture. The cells are not fully sealed, allowing air and moisture to pass through.
  • It typically has a lower density, making it lighter and often more cost-effective. The R-value is around R-3.5 per inch.
  • Open-cell foam excels as a sound barrier and is also more permeable to moisture, which can be beneficial in certain wall assemblies to allow drying. However, it is not recommended for areas prone to direct water exposure.
  • Its flexibility allows it to adapt to building movements, reducing the risk of cracking. For those seeking a budget-friendly yet effective solution, consider this when looking to buy polyurethane foam.

Closed-Cell Polyurethane Foam:

  • In contrast, closed-cell foam has a rigid, dense structure with sealed cells. These cells are typically filled with a blowing agent that enhances its insulating properties.
  • It boasts a higher R-value, typically R-6 to R-8 per inch, providing superior thermal resistance in a thinner application.
  • Crucially, closed-cell foam acts as a high-density moisture barrier and vapor retarder, making it ideal for basements, crawl spaces, and areas exposed to water. It also adds structural rigidity to walls.
  • While generally more expensive, its performance in moisture-prone environments and higher thermal efficiency often justify the polyurethane insulation price.
