Scope of Use

FleeceCote™ is suitable for use as part of a pitched long-run metal roofing system in commercial and non-residential buildings where control of condensation beneath the roof is required. It is typically used in industrial, commercial, agricultural and utility buildings with enclosed or semi‑enclosed roof spaces.

The product is suitable for mild to moderate corrosion environments, corresponding to ISO 9223:2012 corrosion categories C1–C3, when installed on ColorCote® ZinaCore™ or MagnaFlow™ roofing substrates. FleeceCote™ is intended for use in typical New Zealand wind and seismic zones where metal roofing systems are commonly specified and detailed in accordance with NZ standards and industry practice.

FleeceCote™ performs best in roof assemblies that incorporate appropriate roof pitch, detailing, and ventilation to support moisture dissipation in accordance with New Zealand Building Code requirements.

Limitations on Use

FleeceCote™ must be specified, installed, and maintained in accordance with ColorCote® technical literature, installation guidelines, and current warranty terms and conditions. Installation must be undertaken by a ColorCote®‑accredited installer to ensure correct system installation and to maintain warranty eligibility.

The product is limited to use within the conditions, applications, and environmental parameters outlined in the relevant Product Information Sheets. Compatibility with other building elements, materials, and systems is dependent on appropriate roof design, detailing, and construction.

Performance of FleeceCote™ is reliant on suitable roof pitch and adequate ventilation in accordance with the New Zealand Building Code, to allow the fleece layer to dry and perform as intended. FleeceCote™ is not intended to be used outside its stated scope or relied upon for purposes not expressly identified in ColorCote® documentation.
