August 5, 2026 How do I Prevent my Business Sign from Cracking in Extreme Cold?

To prevent a business sign from cracking in extreme cold, the most critical step is selecting materials and installation techniques specifically engineered for thermal resilience. In Saskatchewan’s harsh winters, standard materials often become brittle, but there are several ways we ensure your signage remains intact:

• Choose Aluminum Composite Panels: We recommend aluminum composite (often called Dibond) over PVC. While PVC becomes brittle and prone to cracking when temperatures drop, aluminum composite panels consist of two aluminum sheets bonded to a polyethylene core. This structure resists cracking, warping, and corrosion even at temperatures below -30°C.
• Account for Thermal Expansion: Materials expand and contract at different rates. We prevent cracking by engineering purpose-built gaps into the joints of the sign structure and using flexible fastening systems. This allows the sign to move naturally during deep freezes and sudden thaws without stressing the material.
• Use Cold-Rated Fasteners: We utilize epoxy-anchored fasteners for concrete and mount signs on isolated standoffs. This creates a 3mm gap between the sign and the wall, which breaks thermal bridging and prevents ice buildup from forcing the panel out of alignment or cracking it.
• Apply UV-Laminated Vinyl: Protecting the sign’s surface with high-quality UV laminates prevents moisture from penetrating the edges. Moisture that enters and then freezes is a primary cause of delamination and surface cracking.

We handle the entire process from design to installation with 35 years of local experience to ensure your sign is built for the prairies. If you are planning a new project, contact us for a free quote.

Note: Permit and approval requirements vary by municipality — confirm with the City of Regina before installation. Permit processing and compliance are required; non-compliant signs may incur penalties.
