What This Membership Assures You

Supporting National Best Practice

Retroglaze worked with WGANZ on the development of the Best Practice Guidelines for Retrofit, Replacement, and Insert window installations. These guidelines give installers and homeowners a clear, nationally recognised standard for quality workmanship. As a WGANZ member, we promote these guidelines across our partner network and keep everyone informed about changes to industry standards, regulations, and new products. This helps ensure the advice and solutions we deliver stay current and aligned with best practice.

Accountability, Ethics, and High Standards

As a WGANZ member, Retroglaze follows the Association’s professional code of ethics and operational standards, and we work to embed these expectations across our wider network. This focus on consistency and transparency is increasingly important in a market where quality varies widely. By upholding recognised standards and verifying our products meet or exceed them, we help ensure homeowners receive reliable workmanship and trustworthy guidance.

Protecting NZ Homes from Illegally Labelled and Non-Compliant Windows

New Zealand has recently seen a rise in window products entering the market with incomplete or misleading compliance information. These products can underperform, fail prematurely, or create safety risks. Retroglaze takes a firm position on this issue. The systems we install are tested, verified, and correctly labelled so homeowners can be confident they meet all building code and safety requirements.

Innovation, Iteration, and Testing

How we test, validate, and improve new solutions

Innovation is one of our strengths, but every new idea must prove itself before we introduce it to the network. When assessing new products, we follow structured testing protocols to confirm performance, durability, and compliance. This includes environmental simulation, material compatibility checks, installation stress testing, and real-world performance review. By validating products thoroughly, we ensure that the solutions we offer deliver the results we promise.

Shown is recent testing we completed with All Facade Services to ensure a new retrofit timber solution was compliant with and exceeded the necessary standards laid out by WGANZ.

Championing Excellence

Our WGANZ membership is a key part of how we protect homeowners, support our partners, and lead the industry. By combining ethical practice, rigorous testing, and a strong nationwide network, Retroglaze continues to champion excellence in window performance across New Zealand.
