What Customers Are Saying
Customers overwhelmingly praise the foam insulation boards for exceptional thermal performance and ease of use. Most highlight how simple they are to cut with basic tools like a razor knife and install without special expertise. Reviewers report measurable temperature improvements, with many noting significant drops in garage and shop temperatures. The lightweight, foil-facing design reflects heat effectively and works well for diverse projects from garage doors to windows and basement walls. Customers consistently describe it as great value and versatile for both large-scale and targeted applications. A few mention cutting creates fine particles, and some note the material requires careful handling, but these minor concerns are vastly outweighed by strong overall satisfaction.

Would RecommendI live in south Carolina and have a metal roof on the shed that I work in. I insulated the ceiling with this and it keeps the shed MUCH cooler. I imagine it will help repel the cold in the winter too.
