If you live in a busy area, you’ll know how intrusive outside noise can be. Whether it is the sound of trains or simply everyday street activity, the constant hum isn’t always easy to ignore. For many homeowners, upgrading to new windows in Stevenage isn’t just about energy efficiency or security—it’s also about peace. However, when it comes to uPVC and aluminium windows, which option really performs better for noise reduction?
Understanding the role of windows in noise control
Windows in Stevenage are one of the main entry points for unwanted noise. The materials used in the frames, combined with the type of glazing, seals and installation, all play a big role in how much sound gets through. So, while the frame material matters, it’s essential to consider the whole picture.
How uPVC windows reduce noise
uPVC has become a popular choice across the UK, not only for its affordability and thermal efficiency but also for its sound insulation properties.
Natural insulation
uPVC is a non-conductive material, meaning it doesn’t transfer sound easily. This gives it an edge in reducing outside noise.
Thicker profiles
uPVC frames are slightly chunkier than aluminium ones, which helps block more sound.
Sealing capabilities
Quality uPVC windows often come with multiple seals that prevent both draughts and noise infiltration.
When combined with double or even triple glazing, uPVC windows can make a noticeable difference to the comfort inside your home.
The aluminium window perspective
Aluminium windows have their own strengths, particularly in terms of durability, strength, and sleek aesthetics. They’re often chosen for modern designs and larger window spaces thanks to their slimmer frames.
Conductivity
Aluminium is a conductive material, hence, it can transfer vibrations more easily than uPVC. This sometimes means they’re not quite as effective at dampening noise.
Thermal breaks help
Many modern aluminium windows include thermal breaks—insulating barriers within the frame—which can improve both heat and noise insulation.
Glazing matters
With the right acoustic glazing, aluminium windows can still achieve excellent levels of noise reduction.
Therefore, while aluminium may not have the same natural soundproofing qualities as uPVC, high-quality systems with enhanced glazing can still deliver strong performance.
Other factors that influence noise reduction
It’s not all about the frame. To get the quietest home possible, consider:
Glazing
Double glazing is the minimum standard; nevertheless, acoustic or laminated glass can significantly cut down sound.
Installation
Even the best windows won’t work properly if they’re poorly fitted. Gaps or weak seals let sound straight in.
Home location
The type and volume of noise around your property should guide your choice—occasional background noise is different from constant heavy traffic.
uPVC or aluminium windows: which is better?
In general, uPVC windows perform better in terms of noise reduction due to their insulating qualities and thicker profiles. That said, modern aluminium windows paired with the right glazing can also be a strong option—particularly if style, slim sightlines and durability are high on your list.
If reducing noise is your top priority, uPVC might give you the edge. Nonetheless, the best solution often comes down to the combination of frame material, glazing, and professional installation. For homeowners, upgrading to uPVC and aluminium windows can make your home quieter, more comfortable, and far more enjoyable to live in.
