When a project team compares fiber cement board vs OSB, the conversation usually starts with cost. OSB appears cheaper. It is widely available. Contractors are familiar with it. But when the discussion shifts from initial price to fire risk, compliance, insurance exposure, and long-term liability, the decision often changes completely.
Selecting the correct screws for fiber cement boards is just as important as choosing the board itself. Even the highest-quality fiber cement board can fail prematurely if it is fixed with the wrong fasteners. Cracking, loose panels, corrosion staining, and reduced fire performance are often the result of incorrect screw selection rather than material defects.
Choosing the right facade material in the Baltic region is not just about aesthetics. Buildings in Lithuania, Latvia, and Estonia are exposed to frequent rain, heavy snow, freeze–thaw cycles, and coastal winds, all of which can severely impact facade performance over time.
Fiber cement boards are traditionally used as flat façade and interior panels — but modern architecture increasingly demands curved walls, soffits, and flowing geometries. This raises a critical question: How far can fiber cement boards bend safely without cracking or structural failure?
Fiber cement boards are dimensionally stable materials designed to withstand weather, temperature changes, and mechanical stress. However, they are not entirely immune to moisture absorption or thermal expansion. When installed without
