CodeMark Certified
Certificate CMNZ70173 issued by Bureau Veritas. BCAs are legally required to accept it as evidence of Building Code compliance — faster consents for your projects.
Competitive Pricing
Fully certified, vertically integrated supply chain — every stage from glass to final assembly under one quality system. Most CodeMark-certified manufacturers charge premium prices. We don't.
BRANZ-Verified Performance
Not just claimed R-values. Independently tested and modelled by BRANZ using flixo software. R0.46 thermally broken and R0.37 standard. Use these numbers with confidence.
Consistent Quality
ISO 9001 quality management system. Every component traceable to its source, test report, and production batch. Same quality, every order, every project.

Auckland Region Delivery
Auckland manufactured and assembled. We service townhouse and multi-unit projects across the Auckland region and surrounding North Island areas.
Three Pathways to
Building Code Compliance
Under the Building Act 2004, compliance with the New Zealand Building Code can be demonstrated in three ways.
CodeMark Certificate
A product holds a CodeMark certificate issued by a JAS-ANZ accredited body. Under s.19(1)(d) of the Building Act 2004, BCAs must accept it as establishing compliance with the covered NZBC clauses.
Learn moreAcceptable Solution
Compliance is demonstrated by following an MBIE-published Acceptable Solution (e.g. H1/AS1). For windows and doors, this typically means meeting minimum R-values using independently tested thermal data.
Learn moreAlternative Solution
Compliance is demonstrated through specific technical evidence assessed by a suitably qualified person. Used where a product or configuration falls outside the scope of an Acceptable Solution.
