Spray Cork and Wall Sound Insulation: The Quiet Revolution in Construction

Modern life is noisy. Whether it’s buses thundering down your road in Sheffield, the toddler upstairs practising tap dance in a converted Glasgow tenement, or late-night karaoke from next door in East London, sound pollution isn’t just annoying. It’s constant.

Good wall sound insulation helps, of course. But what if your render could pitch in too? This is where ReveCork steps up. This clever spray cork coating doesn’t just weatherproof your walls. It helps hush the sounds outside them, too.

What is ReveCork?

ReveCork is a natural cork-based render, applied to interior or exterior walls using a specialist spray gun. Once cured, it forms a breathable, flexible, textured coating that bonds to a wide range of surfaces. Yes, even crumbling pebble dash that’s seen better days. It’s waterproof, thermally insulating, crack-resistant and, crucially, brilliant at reducing sound transfer.

A handful of brands manufacture and sell spray cork but when it comes to quality, performance and longevity, it’s hard to beat ReveCork. It’s one of the highest-performing cork-based renders on the market and sold exclusively by Spray Cork UK.

Contractors across the country already use it for eco-friendly retrofits and new-build exteriors. But the acoustic benefits? That’s where it’s making a surprisingly quiet impact.

Why cork works for sound insulation

You might not think of cork as a noise-busting superhero, but it’s got some serious soundproofing credentials. How does it work? Cork is packed with millions of tiny air-filled cells (about 40 million per cubic centimetre to be precise). These spongey cells act as miniature shock absorbers. Instead of sound waves bouncing off hard surfaces, cork’s unique structure helps trap and dampen them. That means less noise travels through walls and less echo bounces around rooms.

In short? Fewer rows about the telly being too loud, less hearing your neighbours cough through the plasterboard and a better night’s sleep all round.

Spray Cork vs traditional soundproofing

Most traditional wall sound insulation relies on bulky solutions. Think secondary walls, acoustic plasterboard, mass-loaded vinyl and the like. They work but they can be bulky and disruptive to install, especially in finished homes. And they’re not exactly budget-friendly either.

Spray cork offers a smarter solution. It adds a layer of acoustic insulation directly onto the wall, with no need to rip the place apart. For retrofits or tricky builds (hello, awkward loft conversions and thin Victorian party walls), that’s a major win.

It also pairs beautifully with existing materials. Contractors using external wall insulation systems or doing refurbishments can add ReveCork as a final finish to improve both thermal and acoustic performance in one go.

Where it works best

Spray cork plays well in lots of scenarios but it really shines in:

  • Terraced housing and semis. A great way to reduce neighbour noise through party walls.
  • Flats and HMOs. Improve privacy in tight living quarters.
  • Offices and studios. Keep sound in (or out) as needed.
  • Nurseries and schools. Lower ambient noise and improve concentration.
  • Converted properties. Bring old walls up to modern standards without major rebuilds.
  • Holiday lets and B&Bs. Quiet rooms translates to better reviews and repeat bookings.

Wall sound insulation isn’t a silver bullet. For full-on soundproofing, you’ll still want proper acoustic design. But ReveCork is a powerful addition that delivers real difference.

What’s it like to apply?

Contractors love ReveCork because it’s fast and straightforward to use. If you’re already comfortable with spray application techniques, adding it to your toolkit is a no-brainer. It’s applied via a hopper gun and compressor, much like other textured finishes.

Spray Cork UK offers full training and support for contractors, plus supply of ReveCork in over 30 colours. Whether you’re working on a smart new-build in Bristol or retrofitting a cottage in the Lake District, there’s a finish to suit.

And because it’s so flexible and grippy, Spray Cork bonds to tricky substrates like brick, render, wood and even metal cladding. That makes it ideal for both domestic and commercial work.

How much sound does it block?

Tests show that spray cork actively reduces airborne sound, particularly in the mid-to-high frequencies where things like voices, music and traffic sit. While it won’t completely block out next door’s dog, it significantly dulls everyday noise, enough to be noticed by occupants.

Did you know? The acoustic benefit increases with thickness, so it can be tailored depending on the space and surface. Contractors often use spray cork wall sound insulation alongside other materials to build a full performance spec.

The bonus: it’s eco-friendly

Sound insulation aside, cork has serious sustainability cred. It’s harvested from cork oak trees, which regenerate their bark without being cut down. That makes it renewable, low-waste and surprisingly kind to the planet.

Spray Cork contains no harmful chemicals, no solvents and no nasty VOCs. It’s breathable (so it won’t trap moisture) and helps regulate interior temperatures too. For homeowners chasing greener upgrades (or councils aiming for Net Zero retrofits) it’s a solid choice.

And for contractors? It’s an easy way to hit sustainability targets and win over new customers without compromising on performance.

Local builds, real results

UK weather isn’t gentle. From sideways rain in Cornwall to frosty mornings in the Peak District, exterior renders take a beating. ReveCork’s resilience to moisture and cracking means it keeps performing year after year, with very little maintenance.

Better still, it keeps sound where it belongs… outside! For contractors working on period properties with thin walls or minimal cavity space (plenty of those in northern towns and major cities like London), that’s a huge plus.

Why contractors are switching

Spray cork wall sound insulation doesn’t just make your life easier. It’s a genuine commercial opportunity. If you’re a contractor looking to stand out from the crowd, adding acoustic performance to your render offering gives you an edge. More clients are asking for comfort, quiet and sustainability, not just a pretty finish.

And with full training, product supply and support from Spray Cork UK, getting started couldn’t be easier.
