When it comes to commercial buildings in New Zealand - from offices and schools to retail spaces and apartments - choosing the right commercial windows is critical. The right windows do more than frame a view; they affect energy efficiency, comfort, compliance, and long-term durability.
At Omega Windows & Doors, we design and manufacture NZ-made aluminium window systems built to perform in our unique environment - ensuring strength, thermal efficiency, and lasting style for every project.
NZ’s building environment is demanding. With strong UV exposure, coastal salt air, and strict New Zealand Building Code requirements, commercial windows must balance form and function.
The right choice can:
Choosing NZ-made aluminium windows means your products are designed for local conditions and backed by local support.
Climate & Weather Resistance
New Zealand’s weather can be unpredictable. Look for commercial window systems engineered to resist air and water infiltration, using robust seals, drainage systems, and corrosion-resistant aluminium - ideal for coastal and high-exposure sites.
Thermal Performance & Energy Efficiency
Windows play a major role in a building’s energy efficiency. Omega’s thermal break technology minimises heat transfer through the frame, while modern glazing options (like double glazing and low-E glass) help regulate indoor temperatures year-round.
Durability & Low Maintenance
High-traffic commercial buildings need durable window frames and hardware that can withstand frequent use and exposure. Omega’s aluminium joinery is built for strength and long-term performance, with minimal maintenance required.
Compliance & Certifications
Always ensure your windows meet NZ standards for performance and safety. Our products are also fully compliant with NZ Building Code performance requirements.
Architectural Flexibility & Design
Every commercial project has unique design goals. Omega’s systems offer flexibility for architects and specifiers - from large spans and custom configurations to a wide range of powder-coated or anodized finishes.
Omega’s 600 Series Commercial is engineered for strength, thermal efficiency, and aesthetic appeal - perfect for modern NZ commercial projects.
Key features include:
Our systems are tested for air infiltration, water penetration, and structural integrity, giving architects and builders confidence in every specification.
Omega’s commercial window systems are trusted across New Zealand — from coastal environments where corrosion resistance is critical, to urban developments demanding thermal performance and style.
Our NZ-made systems have been used in educational facilities, apartment complexes, and office buildings nationwide, delivering performance that lasts.
The right commercial windows for NZ projects deliver more than good looks — they provide long-term performance, efficiency, and peace of mind.
