The primary difference between Foamular 150 and Foamular 250 lies in their density, which directly impacts their compression resistance and overall insulation performance in various applications.
Key Distinctions in Density and Performance
Foamular 150 is characterized as a lower-density insulation product, making it suitable for general insulation needs. In contrast, Foamular 250 is a higher-density product. This increased density provides Foamular 250 with significantly more resistance to compression, which translates to enhanced durability and often superior insulation performance, especially in demanding or load-bearing applications.
Here's a quick comparison:
| Feature | Foamular 150 | Foamular 250 |
|---|---|---|
| Density | Lower | Higher |
| Compression Resistance | Standard | Higher (More resistant to crushing) |
| Insulation Performance | Effective | Better (especially under load) |
| Typical Applications | Walls, standard sheathing | Floors, roofs, foundations, heavy loads |
Practical Applications and Considerations
The differences in density and compression strength make each Foamular product suited for distinct uses:
Foamular 150
This type is ideal for less demanding applications where general thermal insulation is the primary requirement. It provides excellent R-value for its thickness and is commonly used in:
- Standard Wall Insulation: As an insulating sheathing on the exterior of walls, enhancing thermal performance.
- Interior Applications: For insulating basement walls or crawl spaces where heavy loads are not a concern.
- Residential Slab Insulation: Under concrete slabs in homes where typical residential loads are expected.
Foamular 250
Due to its higher compression strength, Foamular 250 is designed for applications that require greater load-bearing capacity and resilience against crushing forces. This makes it suitable for:
- Under Concrete Slabs (Commercial/Industrial): Essential for projects where the slab will bear significant weight, such as warehouses, factories, or large commercial buildings.
- Roofs and Decks: Especially on flat roofs or decks that will experience heavy foot traffic, equipment, or heavy snow loads.
- Foundations and Basements: Where greater resistance to soil pressure or heavy backfill is necessary, ensuring long-term performance.
- Agricultural Buildings: For floors and walls where heavy machinery or livestock might apply pressure.
Choosing the Right Foamular Product
When deciding between Foamular 150 and 250, consider the specific demands of your project:
- Load Requirements: If the insulation will be subjected to heavy loads, pressure, or foot traffic, Foamular 250 is the more robust choice to prevent compression and maintain its insulating properties over time.
- Application Area: For standard wall or light-load applications, Foamular 150 offers effective thermal resistance without the added cost of higher compression strength.
- Long-Term Performance: For critical areas where maintaining insulation integrity under pressure is vital, the higher density of Foamular 250 ensures better long-term performance.
Both Foamular 150 and 250 are excellent choices for XPS rigid foam insulation, providing superior thermal performance and moisture resistance. The key is to match the product's compression strength to the structural and load-bearing requirements of your specific construction project.
