A few years back, we were fitting out a shared office space in Birmingham. We didn’t plan for soundproofing, but once the teams settled in, it was clear the outside noise was distracting.
That was my cue to start learning more about soundproof window options in the UK.
Since then, I’ve worked with several manufacturers. I reviewed product specs, placed orders, and saw the results on real sites. What follows is based on that hands-on experience.
In this article, you’ll get a quick breakdown of six UK-based soundproof window makers I’ve come to trust. Whether you’re building new or upgrading, this list keeps things simple and focused.
If you’re after windows that work harder than standard glazing, you’re in the right place.
Let’s get started!

1. Hugo Carter
There’s something frustrating about being in a great space that just doesn’t sound right.
You can have the perfect layout, top-tier furnishings, even great lighting—but if traffic or plane noise leaks through the windows, it changes everything. That’s the kind of noise most people try to ignore, but Hugo Carter tackles it head-on.
Based in London and Edinburgh, Hugo Carter Ltd has built a name around acoustic precision. Their focus isn’t mass production or generic upgrades—it’s soundproof timber windows and doors crafted to do one thing exceptionally well: block out the noise.
What stands out is how focused they are on science over sales. You won’t find pushy reps here. Instead, their process starts with acoustic specialists who dig into the actual data behind your noise problems.
From there, everything—from design to manufacturing to installation—stays in-house and tightly controlled.

Product Portfolio & Technical Specifications
- Soundproof Casement Windows: Five unique styles that echo different British architectural periods—form meets function without compromise.
- Soundproof Sash Windows: Classic charm with serious noise-blocking tech built in. Ideal if you want traditional aesthetics without traditional flaws.
- High Performance Windows: Designed for major noise exposure—think rail lines, flight paths, or busy city centers.
- Soundproof Secondary Windows: A smart option if you’re working with heritage properties or protected façades that can’t be replaced.
- Tilt and Turn Windows: Great for flexibility, ventilation, and easy cleaning. All while maintaining excellent acoustic control.
Services
One of the first things you’ll notice is how different their process feels. Everything starts with a conversation, not a pitch. They send a trained acoustic specialist, not a salesperson, to your site to take real decibel and frequency readings. That means you’re getting advice backed by data, not guesswork.
Their 7-step service journey keeps things methodical and personal: from the initial enquiry and sound survey, to manufacture updates and installation, all the way through to the post-installation follow-up. You’re guided the whole way.
Installation is done by their in-house teams. No subcontractors, no surprises. Every technician is certified and trained to apply specialist materials like acoustic foam to seal every possible flanking path.w up after the job to make sure the results match the promise.
Accreditations and Awards
- FENSA Registered Installer (Reg No. 37626)
- Glass Qualifications Authority certified installation teams
- FSC-Certified Timber Use – prioritizing responsible sourcing and sustainability
- UK Enterprise Awards 2019 Winner for:

Bottom Line
Hugo Carter delivers exceptional noise reduction with precision-engineered windows designed for performance and peace of mind. Their bespoke builds and deliberate design choices make them one of the few manufacturers that consistently live up to their claims. The drawback is cost—these solutions come at a premium, making them less suited for budget-sensitive projects.
2. The Soundproof Windows
Some brands talk about sound reduction. This one seems to live it. With their London headquarters tucked into Tempo House, The Soundproof Windows brings a purpose-built, no-nonsense approach to acoustic window design that feels less like sales and more like sound engineering with personality.
They’re not trying to do everything—they just want to do one thing really well: restore quiet. And from the way they explain their process, it’s clear they’ve spent years figuring out how.
Everything from the glass thickness to the frame design is calculated, not guessed. And they’ve got the technical chops—and certifications—to prove it.
Their branding says “SILENT by DESIGN,” and honestly, that’s exactly what they deliver. They don’t shout about it. They just show up with tailored, high-performance timber windows and doors, and let the results speak (or not speak) for themselves.
- Address: Unit 6, Tempo House, 15 Falcon Road, London, SW11 2PJ, United Kingdom
- Website: thesoundproofwindows.co.uk
Product Portfolio & Technical Specifications
- Soundproof Sash Windows: Available in tiers—Soundproof (up to 40dB), Soundproof+ (up to 43dB), and Ultra (up to 49dB). These aren’t off-the-shelf frames—they’re tuned for acoustic performance with authentic sash styling.
- Soundproof Casement Windows: Traditional appearance, modern science. Fully sealed when shut to stop noise cold.
- High Performance Tilt & Turn Windows: Their top-tier timber window, delivering up to 51dB in noise reduction. Clean lines with serious stopping power.
- High Performance Secondary Windows: Designed to double down on sound—literally. Installed inside the existing frame, achieving up to 55dB reduction. Ideal for heritage properties or extreme noise zones.
- Soundproof Studio Windows: Made for the sound-sensitive. Rated at Rw 59dB, they’re purpose-built for recording spaces and music production studios.
- Acoustic Doors: Matching French, balcony, and patio doors round out a full-package approach. Noise doesn’t get a back door in.
Services
The Soundproof Windows doesn’t just drop off a product and call it a day—they walk the full service line with you. Their process starts by measuring the problem, not assuming it. Using actual decibel readings and frequency data, they custom-build a system around your space’s unique noise challenges.
But what makes their offering really stand out is the protection they layer on for customers—insurance-backed guarantees, Trading Standards approval, and participation in verified consumer schemes all add peace of mind to peace and quiet.
Installation is a major focus too. Their teams are trained to seal every gap, use advanced fitting tools, and ensure that once it’s closed, it stays quiet. It’s not just craftsmanship—it’s engineered silence.
Accreditations and Awards
- Consumer Protection Association (CPA): All products backed by a 10-year insurance guarantee
- Trading Standards Approved & Buy With Confidence Scheme member
- TrustMark: Government-endorsed for quality and reliability
- Glass and Glazing Federation (GGF): Trusted trade body membership
And on the awards front, they’ve racked up recognition that spans several years:
- Leading Providers of Acoustic Windows & Doors – SME News Awards 2020
- Best Acoustic Window & Door Installation Service – SME Awards 2021
- Best Acoustic Window & Door Installation Company – London – SME Awards 2022
Bottom Line
The Soundproof Windows combines strong acoustic performance with thoughtful design and real customer guarantees. Their expert analysis, flexible product range, and proven results make them a go-to for both homes and studios. The trade-off is material focus, since they primarily work in timber and options may feel limited for those seeking alternative frames.
3. Everest
When a company’s been around since 1965, there’s usually a reason—and in Everest’s case, it’s scale, structure, and staying power. With manufacturing rooted in Kent and Wales and a presence that stretches across the UK, Everest has become one of the most recognized names in the home improvement space.
They’ve leaned heavily into their British identity—joining the Made in Britain campaign and backing it with physical production in the UK. But what’s just as noticeable is their formula: make the process feel local, even when it’s being delivered by a national network.
Everest positions itself as the complete package—manufacture, install, guarantee—backed by decades of experience.
While they cater largely to homeowners, their product specs and certification stack make them a serious player when it comes to commercial-scale credibility.
- Address: Nationwide operations with manufacturing sites in Sittingbourne, Kent, and Treherbert, Wales
- Website: www.everest.co.uk
Product Portfolio & Technical Specifications
- Noise Reduction Glass: Their dedicated acoustic glazing unit uses an asymmetric build—6mm low-iron outer pane + 6.8mm laminated acoustic inner pane with a PVB core. This combo disrupts soundwaves and delivers up to 40dB of noise reduction. Standard double glazing by comparison clocks in at around 33dB.
- Secondary Glazing: Their preferred solution for listed buildings and heritage sites. Everest ranks this above triple glazing for soundproofing, thanks to the deeper air gap that boosts insulation.
- uPVC, Aluminium, and Timber Frames: Available across window styles—casement, sash, tilt and turn—providing flexibility for both performance and aesthetics.
- Triple Glazing: Though not promoted for acoustics, their triple-glazed windows are highlighted for thermal efficiency, achieving A++ energy ratings.
Services
Everest runs a polished, well-structured operation. It starts with a free, no-obligation appointment and ends with professional installation backed by layered guarantees.
Each window is made-to-measure, not pulled from a warehouse. Their local consultants guide customers through the options, and while the engagement leans traditional—it’s structured to ensure consistency. Acoustic performance isn’t just about swapping glass.
They assess how sound is entering the property, which makes for more accurate recommendations. Their warranty game is strong. Standard windows come with a 10-year guarantee, but you’ll also find 20- and 30-year warranties depending on material. Lifetime coverage is optional for those who want extra peace of mind.
Accreditations and Awards
- FENSA Registered Installer – building regulation compliance
- ISO 9001 & BSI Kitemark Certified – including PAS 24 security testing
- British Board of Agrément (BBA) – first UK window company certified
- BFRC Rated – for energy performance
- Secured by Design – crime prevention initiative
- Quiet Mark Certified – acoustic performance endorsement
- Glass and Glazing Federation (GGF) – leading industry trade body
- TrustMark Accredited – government-endorsed quality scheme
- Made in Britain Member – UK manufacturing commitment
Bottom Line
Everest offers the confidence of a long-standing national brand with wide product reach and proven reliability. Their acoustic glazing performs well, especially when combined with secondary units, and their structured service comes with strong protections. The downside is a traditional sales-driven approach that may feel outdated for some buyers.
4. IAC Acoustics
Some companies sell windows. Others engineer silence. IAC Acoustics clearly falls into the latter camp. Based in Hampshire but backed by a global footprint, this UK division is all about acoustic performance at the highest technical level—built not for mass markets, but for projects where the noise stakes are high.
They aren’t trying to retrofit your average home office. Instead, their solutions are precision-built, often steel-framed, and deployed in environments where sound control isn’t just preferred—it’s mission-critical.
That includes laboratories, studios, and test cells where exacting standards must be met, and failure just isn’t an option.
Their UK base at IAC House is where it all comes together: custom design, fabrication, and final assembly. Everything they build is manufactured to order using advanced tools like laser cutting and performance-verified through their own labs. This is acoustic engineering with a capital “E.”
- Address: IAC House, Electron Way, Chandlers Ford, Hampshire, SO53 4SE
- Website: www.iacacoustics.global
Product Portfolio & Technical Specifications
- Performance Ratings: From R<sub>w</sub> 47 (STC-46) all the way to R<sub>w</sub> 68 (STC-68)—which, for context, is well beyond the needs of even the noisiest residential environment. These ratings make them a go-to for recording studios, testing labs, and industrial applications.
- Construction: These aren’t off-the-shelf units. Each system is steel-framed and assembled on site. Laminated safety glass comes standard, with options for fire ratings (E30 to EI90), bullet resistance, or angled glass for reflection control.
- Applications: Think studio booths, control rooms, airport-adjacent properties, and industrial zones. That said, for home studios or homes plagued by aircraft or machinery noise, IAC solutions could make all the difference—if your budget matches the performance.
Services
Working with IAC Acoustics is like hiring a soundproofing SWAT team. This is not a catalogue-order operation. Their service begins with engineering consultation, moves through in-house design, and ends in field-tested installation—with guarantees that the system will perform exactly as promised.
Their systems are fabricated in the UK, shipped in modular form, and assembled by highly trained installation crews. Performance isn’t assumed—it’s tested on-site. If your project has to meet acoustic targets under contract, IAC is the kind of partner who signs off with confidence, backed by lab reports and field results.
It’s engineering-first, not sales-first. And that makes all the difference.
Accreditations and Awards
- UL, BS, and EN Fire Ratings: Integrated into product design for high-stakes environments
- In-House R&D and Testing Facilities: Enabling lab-grade validation before anything goes live
- Trusted by Architects and Acousticians: Especially in sectors like aviation, medical research, automotive, and media production
- Global Engineering Credibility: Their UK division is part of a wider organization known for executing large-scale, sound-critical projects
Bottom Line
IAC Acoustics delivers some of the highest-performing, lab-tested window systems available, trusted in studios, industrial sites, and mission-critical spaces. Their Noise-Lock® solutions are engineered for measurable and certified silence, making them stand out from typical acoustic products. The drawback is cost and design flexibility, since their focus is on function over aesthetics.
5. Bereco
Some brands make windows. Bereco makes a point. From their South Yorkshire headquarters, they’ve carved out a strong position in the UK timber window market—not just for aesthetics, but for performance, especially when it comes to acoustic control.
Since 2003, Bereco has focused exclusively on high-spec, sustainably sourced timber products. They don’t just meet standards—they aim to exceed them, and that mindset runs through everything they do.
Their product lines are tailored to customers who want a mix of heritage charm, modern efficiency, and third-party-verified performance.
What really makes them stand out is their attention to detail. From design consultations to lead times and certifications, Bereco doesn’t do half promises. Their noise-reducing Ambient Range is a good example—it’s not just about glass; it’s about the full window system working in harmony.
- Address: Units 4-5, Aspen Court, Centurion Business Park, Bessemer Way, Rotherham, South Yorkshire, S60 1FB
- Website: www.bereco.co.uk
Product Portfolio & Technical Specifications
- Performance Ratings: Certified to reduce sound by 33dB to 42dB, with their highest-rated option earning a Bluesky A classification—a rare full-system accreditation that covers not just glass, but frames, seals, and installation integrity.
- Acoustic Glass: Uses laminated glass with a special interlayer membrane that absorbs sound energy before it enters your space.
- Dual Gaskets: Seals the frame tight to eliminate air gaps, boosting both noise insulation and weatherproofing.
- Engineered Timber Frames: Provides a solid, natural barrier that outperforms other frame materials acoustically.
- Window Types: Available in sash and casement designs, offered in contemporary, heritage, and traditional styles—giving you performance without sacrificing visual integrity.
Services
Bereco’s customer process is polished but personal. It starts with a free design consultation that’s about more than just picking shapes and colors—it’s about aligning style, budget, and technical needs.
They commit to lead times of 6–8 weeks, which suggests solid control over their production and logistics. And they back every order with a 10-year warranty on factory finishes and manufacturing defects, along with a 30-year timber warranty—an impressive gesture in a space where long-term reliability matters.
Their service model works equally well for architects, developers, and discerning homeowners. If you’re the type who wants technical precision, reliable timelines, and support that doesn’t disappear after install, they tick the right boxes.
Accreditations and Awards
- Bluesky Noise Reducing Windows Certification – including A-rated classification for their 42dB system
- Bluesky Enhanced Security Scheme – meeting PAS 24:2022 standards
- Secured by Design – police-endorsed security accreditation
- FENSA Approved Installer – ensuring regulatory compliance
- Bluesky Coatings & Finish Quality Scheme – maintaining long-term product aesthetics

- FSC® and PEFC Certified – guaranteeing responsibly sourced timber across all products
Bottom Line
Bereco combines acoustic performance with strong design and verified system-wide certifications. Their timber windows balance appearance with function, making them a reliable choice for eco-conscious and heritage projects. The limitation is material scope, as they focus solely on timber and may not suit projects needing alternative frame types.
6. The Sash Window Workshop
There’s something deeply satisfying about a business that knows exactly who it’s for—and The Sash Window Workshop is one of those rare companies. Based in Berkshire and proudly part of the Made in Britain campaign, they’ve been crafting traditional timber windows for over 30 years, with a laser focus on period properties.
Their operation isn’t flashy, but it is deeply trusted. In fact, around half of their work comes from repeat clients and word-of-mouth referrals. That says a lot.
From listed Georgian homes to Victorian terraces in conservation areas, they understand what makes heritage windows work, and more importantly, how to make them better.
Everything is made in-house at their Bracknell workshop. They’ve built their reputation not just on style, but on substance: durable timber, quality installation, and meaningful soundproofing through thoughtful detailing and design.
- Address: 4 Kiln Lane, Bracknell, Berkshire, RG12 1NA
- Website: www.sashwindow.com
Product Portfolio & Technical Specifications
- Window Types: Traditional sash windows, casement windows, and matching French doors. They offer both full window units and replacement sashes fitted into original frames—perfect for preserving listed features.
- Frame Materials: Their go-to is Accoya, prized for its longevity and stability (they’re an approved manufacturer). They also offer Sapele Hardwood and European Oak, depending on the project.
- Double Glazing: Standard on new windows, offering significant improvement over single-pane designs.
- Draught-Proofing: Every unit is factory-sealed with high-quality gaskets, tackling one of the biggest sources of sound leaks: air gaps.
- Precision Installation: Their team ensures every frame fits snugly, reducing vibration and ambient sound transmission.
Services
Their process is as tailored as the homes they work on. It starts with a detailed on-site survey by a knowledgeable sales surveyor—someone who understands heritage architecture, not just pricing sheets.
From there, they manage manufacture and installation in-house, ensuring consistency from start to finish. They don’t dabble in fast fixes or off-the-shelf compromises. Everything is built to match the property’s character while solving practical problems like noise, heat loss, and drafts.
That level of assurance doesn’t just look good on paper—it makes a difference when you’re dealing with projects that need both compliance and craftsmanship.
Accreditations and Awards
- Made in Britain – Certified UK manufacturer
- FENSA Registered – Installation compliant with building regs
- Which? Trusted Trader – Consumer confidence you can count on
- Trustpilot Rating: ‘Excellent’ based on consistent customer satisfaction
- The Guild of Master Craftsmen – Long-standing member since 1994
- British Woodworking Federation (BWF) – Trade body backing for timber expertise
- FSC® Certified – Responsibly sourced materials
- Accoya Approved Manufacturer – Specialist in high-performance timber
- SafeContractor Approved – Commitment to health and safety best practice
Bottom Line
The Sash Window Workshop specializes in blending authentic craftsmanship with modern comfort, making them ideal for period and conservation projects. Their joinery expertise, double-glazing, and draught-proofing deliver quiet without compromising traditional aesthetics. The drawback is limited acoustic data, since their performance isn’t verified with formal decibel ratings.
