Preparations and Best Practices for Using Spray Foam in Attics
There are many key preparation steps that professional contractors should take when getting ready for a project using spray foam insulation in attics. Let’s examine them.
1. Job Site Assessment
Applying spray foam in most environments follows a standard procedure. However, attics present unique challenges due to not being used as often, the presence of variable moisture levels, not being inspected as often, and other factors.
Before beginning, it’s important to be sure to conduct a thorough and comprehensive job site assessment to identify any potential risks that could impact the spray foam insulation in the attic. Aspects a contractor should inspect that could pose challenges to the spray foam process include:
- Structural integrity – You or your operator will want to check for any signs of damage or weakness in the attic’s structure, including problems with any beams, rafters, electrical wiring, and the roof.
- Moisture issues – Look for signs of existing moisture problems, such as leaks or condensation buildup, which must be addressed prior to the spray foam being applied. The new spray foam insulation in the attic will help to prevent further moisture and mold growth.
- Existing insulation – Assess any existing insulation materials to determine if any of them need to be removed or managed before applying new spray foam in the attic.
2. Environment Preparation
As attics feature fluctuating temperatures and humidity levels, it’s extremely important for a professional to prep the environment so that it aligns with the proper guidelines required for spray foam. Before using spray foam in attics, do the following to create optimal conditionals for application:
- Measure humidity levels – Be sure to manage the humidity levels in the environment, as high humidity can negatively affect the expansion of spray foam.
- Ensure a proper temperature – Assess the attic’s temperature to make sure it is within the manufacturer’s recommended spray foam product temperature.

3. Proper Ventilation
As professional contractors are aware, proper ventilation is essential in every project. However, ensuring effective ventilation when using spray foam in attics can be particularly challenging as the confined space makes it more difficult to manage airflow consistently throughout the entire process.
Tips for applying spray foam in attics with proper ventilation include:
- Installing temporary ventilation fans
- Spraying in sections
- Allowing time between layers
- Avoiding blocking any vents with foam
- Adjusting the spray pattern to avoid overspray buildup
Tips for Choosing the Right Attic Spray Foam for Your Project
Choosing the correct spray foam for insulation in attics is essential to ensure you meet your customers’ standards and expectations. There are two different types of spray foam insulation, open-cell, and closed-cell, with factors like moisture control, application areas, and valve requirements that must be taken into account.
Explore the different features of both to decide which spray foam product is the best choice for the specific attic you are working in.
Open-Cell Foam
If your customer is looking for soundproofing and cost-effectiveness, open-cell foam may be the way to go. Some benefits of using open-cell spray foam in attics include:
- Excellent soundproofing capabilities
- Lightweight, expansive foam structure
- Cost-effective for large areas
- Available in both injectable and sprayable foams
- Acts as an air barrier with moisture resistance
Closed-Cell Foam
If the attic or customer requires maximum insulation and moisture resistance, closed-cell foam might be the better option. Some features of using closed-cell foam include:
- Resistance to mold growth
- Creating an effective air and moisture seal
- A higher R-value per inch
- Suitability for concrete lifting applications
- A tight cell structure that enhances water resistance
