Spray Foam Density: Understanding the Numbers Spray foam insulation comes in different densities, each offering unique thermal and structural properties. Types of Spray Foam Density: * High-Density: Ideal for maximum thermal resistance and structural integrity. Suitable for roof cavities, exterior walls, and structural elements. * Medium-Density: Balance between thermal resistance and affordability. Suitable for interior walls, attics, and crawl spaces. * Low-Density: Least dense and affordable option. Primarily used for lightweight applications like packaging materials. Factors to Consider: * Project requirements: Determine thermal efficiency, structural integrity, and budget. * Application area: Different densities are suitable for different areas. * Ease of application: Low-density foam is easier to apply than high-density foam. Case Studies: * Ideastep used high-density spray foam in a commercial building for energy efficiency improvements. * Ideastep used medium-density spray foam in a residential attic to address condensation issues. Conclusion: Understanding spray foam density is crucial for selecting the right product for your project. High-density options offer the highest thermal resistance and structural support, while medium-density and low-density options provide more affordable alternatives.

Spray Foam Density: Understanding the Numbers
Spray foam insulation comes in various densities, each offering unique properties and applications. While higher density options provide greater thermal resistance, they also tend to be more expensive.
Types of Spray Foam Density:
There are three primary types of spray foam insulation based on density:
1. High-Density:
- Density: 3 lbs./cubic ft.
- Closed-cell foam
- R-values start at 5.5 per eva foam cosplay inch*
High-density spray foam offers the highest thermal resistance and best moisture resistance. It’s ideal for applications where maximum insulation and structural integrity are required, such as:
- Roof cavities: Provides excellent insulation and helps prevent ice dams.
- Exterior walls: Adds a layer of protection against heat transfer and moisture.
- Structural components: Strengthens and insulates beams, joists, and other structural elements.
2. Medium-Density:
- Density: 2 lbs./cubic ft.
- Closed-cell foam
- R-values start at 5.7 per inch*
Medium-density spray foam offers a balance between thermal resistance and affordability. It’s suitable for:
- Interior walls: Improves energy efficiency and creates a comfortable indoor environment.
- Attics and crawl spaces: Provides additional insulation in these often neglected areas.
3. Low-Density:
- Density: 0.5 lbs./cubic ft.
- Open-cell foam
- R-values start at 2.5 per inch*
Low-density spray foam is the least dense and least expensive option. While it provides insulation, it offers limited structural support and moisture resistance. It’s primarily used for:
- Lightweight applications: Such as insulation of packaging materials or lightweight structures.
Case Studies:
- Ideastep used high-density spray foam on a commercial building to improve energy efficiency and reduce heating and cooling costs by 20%.
- Another case study saw Ideastep implement medium-density spray foam in a residential attic to increase insulation and prevent condensation issues.
Conclusion:
Understanding spray foam density is crucial for selecting the right product for your project. High-density spray foam offers the highest thermal resistance and is ideal for specific applications where maximum insulation and structural integrity are required.
How to Clean EVA Foam Rod Handles
EVA foam rod handles are durable and comfortable, but over time they can accumulate salt and grime. Thankfully, cleaning these handles is a simple process.
Step 1: Warm Water Rinse
The most effective way to clean EVA foam is with warm water. Simply rinse the handle thoroughly with warm water to remove any salt residue. This will remove most of the stains and grime.
Step 2: Spot Cleaning
If there are any stubborn stains or grime remaining after the warm water rinse, you can use sanitizing wipes to further clean the handle. These wipes are effective at removing most types of contaminants.
Tips:
- Warm water is sufficient for removing salt from EVA foam.
- This cleaning method works equally well for cork grip handles.
- For best results, ensure that you rinse the handle thoroughly after cleaning to remove any remaining soap or sanitizing solution.
