As a spray foam installer you play a vital role in enhancing energy efficiency and comfort in residential and commercial buildings. However, landing that coveted installer job means impressing potential employers during the interview process.

I’ve been in the spray foam industry for over 10 years During that time, I’ve sat in on numerous installer interviews In this article, I’ll share insider knowledge on 13 common spray foam installer interview questions. I’ll provide example responses to help you highlight your skills, experience, and passion for this field.

• Ensuring adequate ventilation of work areas
• Following all manufacturer instructions for safe handling and disposal

Stress that you are committed to ongoing safety training and that you can create a safety culture on any job site.

2. How do you calculate the amount of spray foam needed for a job?

Accuracy matters in this field. Employers want to see you have the math skills and technical knowledge to estimate spray foam requirements In your response, explain your process for measurements and calculations based on factors like

3. What experience do you have with different types of spray foam?

There are two main types – open cell and closed cell. Be ready to explain the unique properties and appropriate applications of each. For instance, open cell foam is good at sealing out air but not so good at keeping vapor out. Closed cell foam offers superior density and insulation performance.

Employers want to see that you have the technical knowledge to choose the right foam for each project.
