Closed cell insulation foam is a spray-applied insulation material designed to provide thermal insulation and, depending on the product and application, structural properties. Its spray-applied nature allows the foam to follow suitable surfaces and reach irregular areas and voids that can be difficult to insulate using conventional materials.
PURL-SP32 is a spray-applied foam with insulating and structural properties, designed for a wide range of applications. It can be used for insulating homes, roofs, factories and chicken sheds, as well as specialist applications such as boat hulls, moulds for iceboxes and refrigerator cabinets, artificial rock construction and selected void-filling applications.
This versatility makes PURL-SP32 a practical option where a spray-applied insulation solution is required for suitably prepared surfaces and specific project requirements.
When selecting polyurethane spray foam for an insulation project, it is important to understand the differences between open-cell and closed-cell foam. Each type has different thermal, moisture and vapour characteristics, so the appropriate solution depends on the application and project requirements.
Open-Cell Foam: has a more flexible structure with interconnected cells. It can provide thermal and acoustic insulation, but generally has lower thermal resistance per unit thickness and greater vapour permeability than closed-cell foam.
Closed-Cell Foam: has a denser cellular structure and generally provides higher thermal resistance per unit thickness than open-cell foam. Depending on the product, it can also provide resistance to moisture and vapour transmission. Its more rigid structure can contribute to structural properties where the product is designed for this purpose.
PURL-SP32 is a spray-applied closed-cell foam with insulating and structural properties. It can be used across a range of applications, including homes, roofs, factories, chicken sheds, boat hulls, moulds for iceboxes and refrigerator cabinets, artificial rock construction and selected void-filling applications.
The spray-applied nature of PURL-SP32 allows it to be used across a range of insulation, structural and specialist applications. Its insulating and structural properties make it suitable for applications where foam needs to conform to suitable surfaces, shapes or voids.
PURL-SP32 can also be considered for a range of other specialist applications. Application suitability should be assessed based on the substrate, application conditions and specific requirements of each project.
