Saturated vs. Laminated Roofing Membranes – Which is Better?

Question: Describe the difference between saturation and lamination and why is it important?

Answer: Saturation vs lamination creates a very different acting sheet, especially when you’re looking at single-ply systems.

With lamination, there are different layers of the roof membrane – polymer, scrim and then the polymer from the bottom to top. Lamination is just a straight almost gluing together of those layers. They can part very easily and you’ll see a lot of failure in those roofs for that same reason.

Saturation, in contrast, has the polymer moving through the whole scrim so it’s a continuous face through the whole membrane. This keeps the membrane from actually delimitating or coming apart. Saturation will not allow that to happen.
