The TopHat roofing system's unique design includes a deflection limiter, allowing for a sturdy, structural attachment between existing purlins. This feature is especially helpful when applied in high-load roof zones and meets reduced clip spacing mandated by new building codes. Clips can be spaced as required in the critical edge and corner zones without reinforcement of the existing steel.
TopHat's deflection limiter is particularly beneficial in hurricane-prone coastal areas, where stringent engineering requirements are in place.
