The NOVA-SK membrane system is a two-layer, self-adhesive bitumen waterproofing system designed for exposed flat roofs, balconies, and similar applications. The only bitumen roofing membrane with a completely self-adhered flameless installation, making it an ideal solution for projects where torch-on systems are not permitted or preferred.
Both the base sheet and cap sheet feature strong self-adhesive properties that create a robust watertight bond during installation. The NOVA-SK cap sheet is finished with natural grey slate chips that provide UV protection and a clean, consistent appearance. The membrane system offers proven resistance to weather, temperature variation, and general atmospheric conditions, supporting a service life of at least 20 years in New Zealand climates.
NOVA-SK is suitable for use on plywood and concrete substrates and can be installed nationwide as part of a standard cold roof system. The system is CodeMark Certified and BRANZ Appraised, complies with the New Zealand Building Code, and is supported by a 20-year material warranty.
