Glass Protection & Treatments
- Glass Protection & Treatments help keep windows, balustrades, splashbacks and shower screens crystal-clear for years. From nano-coatings that repel dirt to UV films that cut glare and fading, explore solutions designed for New Zealand’s tough coastal and alpine climates. Protect your investment and reduce cleaning time—browse the curated range below.
Untreated glass looks pristine on day one, but our salty air, strong UV and hard water can quickly etch, stain and cloud the surface. Investing in the right protection or treatment not only preserves clarity and appearance, it can also extend the service life of glazing, minimise maintenance, and even improve thermal performance. Whether you are specifying for a commercial façade or renovating a bathroom, this guide will help you choose with confidence.
1. How glass protection works
- Nano-coatings chemically bond to the silica in glass, creating an ultra-thin, hydrophobic layer that repels water and contaminants. Ideal for showers, pool fencing and balustrades.
- Protective films are applied to the interior or exterior face and can reduce UV ingress, add privacy, or deliver shatter resistance.
- Surface sealants are wipe-on liquids that fill microscopic pores, making glass smoother and easier to clean.
- Ceramic frits & sacrificial coatings shield glass during construction, preventing cement splatter and scratches.
2. Key decision factors
Environment: Coastal projects suffer accelerated salt corrosion, while alpine areas face freeze-thaw cycles. Choose a treatment tested for your micro-climate.
Location: Interior wet areas require water-spot resistance; exterior glazing benefits from UV and abrasion protection.
Longevity: Professional nano-coatings can last 10+ years with minimal top-ups. DIY sealants usually need annual reapplication.
Maintenance: Some products require a simple neutral-pH wash, while others need specific cleaners to maintain the warranty.
3. Compliance and standards
While the NZ Building Code does not mandate protective coatings, many suppliers test to ASTM C1376 for durability and EN 1096 for solar control. Always request documentation and ensure the base glass itself meets NZS 4223.
4. Where glass protection is commonly used
- Frameless showers and interior doors
- Commercial curtain walls and windows
- Kitchen splashbacks, balustrades and pool fencing
- Heritage façades requiring invisible conservation
- Garage door vision panels and garage doors
5. Installation & maintenance tips
- Surface prep: Glass must be fully cured, clean and grease-free. Any scratches will be sealed in.
- Climate control: Apply between 10 °C and 30 °C with low humidity for optimal bonding.
- Cure time: Most coatings are touch-dry within minutes but require 24–48 h before water contact.
- Cleaning regimen: Avoid abrasive pads and high-alkaline detergents. A microfibre cloth and mild soap are usually sufficient.
6. Cost breakdown
- DIY wipe-on sealant: $15–$25/m²
- Professional nano-coating: $40–$70/m² including labour
- Solar control film: $80–$120/m² depending on performance grade
