Crystal Thermal & Non-Thermal
Crystal redefines what a window can be.
Built on patented Self-Supporting Window System (SSWS) technology, Crystal delivers the highest glass-to-frame ratio available in New Zealand — maximum light, minimum frame, uninterrupted views.
This is precision engineering designed to disappear into your build.

Crystal's ultra-slim sightlines maximise glass area, bringing more light and more landscape into every space.
Unique TouxLock™ steel corner jointing creates the strongest, most durable aluminium joinery system in New Zealand. Engineered to handle — and withstand.
Crystal exceeds standard weather resistance by more than double, tested to Extra High and Extreme wind zone pressures. Whatever the New Zealand climate throws at it, Crystal holds.
Self-supporting technology reduces on-site time and cost. Fewer complications. Faster installs.
Performance you can feel. Crystal Thermal takes the precision engineering of the Crystal system further — adding thermal break technology that keeps your home warmer, quieter, and more energy-efficient year-round. Temperature affects how we live. Crystal Thermal is built around that truth.
As energy costs rise and comfort expectations grow, double glazing alone isn't enough. Crystal Thermal goes further with advanced thermal break technology — significantly reducing heat loss and condensation, while supporting double and triple-glazed configurations for maximum performance in any climate.
Advanced thermal break technology reduces heat loss and condensation — keeping interiors comfortable, healthy, and energy-efficient year-round.
Supports double and triple-glazed configurations for increased thermal comfort and superior sound control in any climate.
Engineered to hold larger glass panels — so you get the thermal performance without giving up the views.
Tested to withstand New Zealand's harshest conditions and engineered beyond the minimum standard. Crystal Thermal holds.

Technology
TouxLock™ Technology
At the heart of both Crystal systems is TouxLock™ — a corner jointing system that sets a new standard for structural integrity. The corner casting ties each joint with precision, creating a connection that's stronger, tighter, and leak-free.
Crystal units are tested to Extra High wind zone Ultimate Limit State pressures of ±2130 Pa, with select units rated to Extreme wind zone at ±2500 Pa — with zero permanent damage or deformation.
