The main difference between APP and SBS roofing membranes lies in their composition and performance. APP (Atactic Polypropylene) membranes are a type of modified bitumen that perform exceptionally well in high-temperature conditions, thanks to their improved UV resistance and thermal stability. On the other hand, SBS (Styrene-Butadiene-Styrene) membranes provide excellent flexibility and functionality in colder climates, rendering them suitable for areas experiencing considerable temperature variations.
