When it comes to replacing your windows, there’s no shortage of opinions, advice – and misinformation. At NuView, we speak to customers every week who have heard all sorts of things about double glazing that simply aren’t true.
So, let’s clear the fog. Whether you’re upgrading your old windows or building your forever home, here are the most common double-glazing myths – busted.
🔍 Myth 1: All double glazing is the same
Not true. While double glazing always involves two panes of glass with a sealed space between them, the quality varies massively. The size of the gap, the type of glass, the frame material, and even the gas used between panes (like argon) all affect insulation, soundproofing and energy efficiency.
At NuView, we use A-rated glass units, high-performance seals, and frames built for Scottish weather – so you’re not just buying “double glazing”, you’re investing in long-term comfort and savings.
🔇 Myth 2: It doesn’t help with noise reduction
Many people assume that double glazing is only for keeping heat in – but it’s also brilliant for keeping noise out. If you live on a busy road, near a school, or just want a more peaceful home, quality double glazing can significantly reduce outside noise.
For extra acoustic insulation, you can even upgrade to laminated or thicker glass.
💸 Myth 3: It’s too expensive and won’t save you much
Good windows are an investment – but they absolutely pay off. Poorly insulated windows can account for up to 25% of heat loss in a home. With energy prices what they are, efficient double-glazed units can help reduce heating bills year after year.
Plus, modern windows require less maintenance and can increase your property value and kerb appeal.
🧽 Myth 4: Condensation means your windows are faulty
This one comes up a lot – and the answer depends on where the condensation is.
- On the outside of the glass? That’s actually a good sign. It means the windows are insulating well and not letting heat escape.
- Between the panes? That’s different – it can mean the seal has failed and may need replacing.
At NuView, we only install units with toughened seals and warranties, so your glazing performs properly year-round.
🪟 Myth 5: You can’t get double glazing in traditional styles
Absolutely not true. You don’t need to compromise on looks to upgrade your windows. We install timber-look uPVC, sliding sash styles, and even heritage-style glazing bars – perfect for period properties and conservation areas.
From modern minimalism to classic charm, we’ll help you find a style that fits your home.
