As the UK experiences increasingly frequent heat waves, business owners need to be aware of the potential damage extreme temperatures can cause to outdoor signage.
Acrylic signs are particularly vulnerable to heat
Acrylic signs are particularly vulnerable to heat. At temperatures above 80°C (which can be reached on south-facing surfaces in direct sunlight), acrylic can begin to warp and deform. This is especially problematic for flat-cut letters and tray signs where dimensional stability is crucial.
Vinyl graphics and wraps can also suffer in extreme heat
Vinyl graphics and wraps can also suffer in extreme heat. The adhesive can soften, causing lifting and bubbling, while the vinyl itself may shrink or crack. This is particularly common on vehicle wraps where engine heat compounds the problem.
LED lighting systems, while generally robust, can...
LED lighting systems, while generally robust, can experience reduced lifespan when consistently exposed to high temperatures. Heat causes LED modules to work harder, potentially leading to premature failure or colour shifting.
To protect your signage investment, we recommend
To protect your signage investment, we recommend: regular inspections during summer months, choosing heat-resistant materials for south-facing locations, ensuring adequate ventilation behind illuminated signs, and considering UV-resistant laminates for printed graphics.
