Differences You’ll Notice

Sikaflex® NP 1 is a polyurethane sealant frequently specified for commercial roofing, façade systems, and higher-movement joints. HP4 is positioned for siding, window, and trim installations requiring efficient application, faster tack-free timing, and broader temperature flexibility. Contractors selecting between the two should consider project type: commercial façade and roofing applications versus residential siding and window installations.
