Choosing the Right Rigid Sign Material in NYC
Selecting the ideal substrate is the foundation of any successful commercial signage project. In New York City, signs must withstand temperature swings, moisture exposure, and strict architectural standards. This guide breaks down the physical properties and best applications for Sintra board, Dibond ACM material, and HDU foam.
What Is Sintra Board?
Sintra board is an expanded rigid PVC (polyvinyl chloride) sheet material featuring a smooth matte finish. It is lightweight, flame-retardant, and highly durable for interior commercial environments.
What Is Dibond & ACM Material?
Dibond material (Aluminium Composite Material / ACM) consists of two 0.3mm aluminum sheets thermobonded to a solid polyethylene core. It is the gold standard for rigid outdoor signage.
What Is High Density Urethane (HDU) Foam?
HDU foam (High Density Urethane) is a dense, closed-cell synthetic material engineered for carved, routed, and sandblasted 3D dimensional signs. Unlike wood, HDU foam will never rot, warp, or absorb moisture.
