Common Myths About Double Glazing – Debunked

When it comes to double glazing, there are plenty of common misconceptions that often cause homeowners to delay upgrading their windows. Whether it’s uncertainty around cost, appearance, or whether double glazing is worth it in a mild climate, misinformation can lead to missed opportunities for improving home comfort and efficiency.

At Ryan Double Glazing, we specialise in retrofitting double glazing into existing aluminium joinery for homeowners in Tauranga, Mount Maunganui, Papamoa, and Te Puke. In this article, we debunk some of the most common myths about double glazing — so you can make an informed decision about upgrading your home.

❌ Myth 1: You Have to Replace the Entire Window Frame

✅ Fact: You can upgrade your windows without replacing the frames.

One of the biggest misconceptions is that double glazing requires completely removing your existing aluminium joinery. This isn’t true. As long as your frames are in good condition, we can replace the single-glazed panes with sealed double-glazed units — using your current frames. This process is quicker, less disruptive, and more affordable than full window replacement.

❌ Myth 2: Double Glazing Doesn’t Make Much Difference in Tauranga’s Mild Climate

✅ Fact: Double glazing makes a noticeable difference year-round.

Even in places like Tauranga, Mount Maunganui, Papamoa, and Te Puke, where the climate is relatively mild, single-glazed aluminium windows can lead to significant heat loss in winter and unwanted heat gain in summer. Double glazing helps stabilise indoor temperatures, keeping your home warmer in winter, cooler in summer, and noticeably more comfortable all year round.

❌ Myth 3: It’s Too Expensive for the Benefits

✅ Fact: Retrofitting double glazing is more affordable than most people expect.

Because we retrofit into your existing aluminium joinery, the cost is significantly less than a full window replacement. Plus, double glazing reduces heating costs, prevents condensation damage, and can even boost your property’s value — making it a smart investment for homeowners.

❌ Myth 4: Double Glazing Is Only for New Homes

✅ Fact: Retrofitting is designed specifically for existing homes.

The majority of our customers live in homes with existing aluminium joinery, often built in the 1980s, 1990s, or early 2000s. Our retrofit process allows homeowners to upgrade their glass without changing the frames — preserving the appearance of the home while massively improving energy efficiency and comfort.

❌ Myth 5: Double Glazing Only Helps with Heat – Not Noise

✅ Fact: Double glazing reduces noise significantly.

Many of our customers in busy parts of Mount Maunganui, Papamoa, and Tauranga are surprised at how much quieter their homes become after installing double glazing. It’s highly effective at reducing outside noise from traffic, neighbours, and general street activity.

❌ Myth 6: Double Glazing Will Look Bulky or Obvious

✅ Fact: Retrofitted double glazing is sleek and unobtrusive.

Our double-glazed units are designed to fit neatly into your existing aluminium frames. There is little noticeable difference in appearance, but the change in comfort, warmth, and noise levels is substantial.
