Structure-Insulated Siding

Structure siding beats fiber cement siding … hands down.


  • Structure siding will never need painting, scraping or caulking.
  • Fiber cement siding requires periodic maintenance to prevent it from absorbing moisture, which can make it crumble and delaminate. All seams must be caulked and any scratches, dents or chips touched up with paint to prevent moisture infiltration — and when they occur on the backs of the panels, they’re hard to see and correct.


  • Structure siding is certified to withstand the impact of installation without chipping or cracking, and it won’t buckle or warp under normal seasonal temperature changes. It will also keep its color without excessive fade.
  • Fiber cement siding can be brittle and can crack and crumble under impact. It is also a painted surface, which will need to be repainted to stay looking fresh.


  • Structure siding uses an engineered installation system that links panels together to ensure a tight, straight, beautiful fit against your home’s exterior.
  • Fiber cement siding is installed by randomly nailing along one edge. Loose boards and minor flaws in exterior walls can require ugly face nailing to make the panels lay flat.
