Regular, Summer, Winter Grades…What’s the Difference?
Here at Yield One, we work with UPC to offer our customers a variety of open and closed cell foams. UPC offers several types of closed-cell foams to which many come in Regular, Summer, and Winter Grades. UPC even offers a Super Winter Grade!
The main difference is how the speed of the foam application interacts with the surface temperature. For the best results, use the grade of foam that is most applicable to your current weather conditions at your jobsite!
