Tip of the Week: Can you Mix Insulation Types on a Job?

Posted on October 25, 2016 within

PFT installation expert Jared answers the question about whether traditional EPS insulation can be mixed with premium Neopor insulation on a siding job.

Traditional EPS insulation and premium Neopor insulation can be mixed on a job, however there are a few important things to keep in mind.


Make sure the panels you are using are the exact same thickness and profile. Even a slight difference in the foam panels can make a huge impact on the job


Premium Neopor insulation must be protected from prolonged exposure to sunlight. Make sure it is stored in the appropriate packaging at the jobsite. The white opaque bag helps protect Neopor from the sunlight.


Finally, make sure the homeowner has approved the use of mixed materials on their home.
