Soundproof Casement Windows

Casement windows are one of the best noise insulation for windows as they provide high levels of security and comfort to homeowners, workers and hotel guests across the UK.

They can also give you the very best solution for soundproofing a property. Our bespoke soundproof casement timber windows can achieve a dramatic noise reduction, far greater than what is possible with ‘regular’ double glazing.

We’re talking up to 45dB. (Scroll down this page to hear what that sounds like.) And you can learn exactly how much noise reduction you need when you book a no obligation initial visit.

Would you like to bring a new level of tranquillity to a particular property? Expect to be surprised by the dramatic difference we can make with acoustic soundproofing.

Noise harms. According to the World Health Organisation, those living with noise pollution of over 55dB are likely to suffer health problems. In London, this affects 1.6 million people.

Tranquility heals. Fitting a property with noise reduction windows can have a hugely healing impact on whoever lives or stays there.

You can reduce noise by up to 45dB. This far outperforms what’s possible with ‘regular’ double glazing.

So why choose us?

Hugo Carter is the UK’s leading provider of noise reduction windows; we call them ‘Silent Windows’. What sets us apart? From what our clients tell us, we believe it’s down to three things:

Our Approach. We won’t sell to you. Our Initial Visit is from a specialist, not a salesman. On that visit, they’ll help you understand exactly what you need, walk you through your best noise reduction options, and give you a full noise survey.

Our Products. No-one in the UK is able to offer you more advanced ‘noise reduction’ windows, coupled with outstanding craftsmanship. Every window or door is bespoke. Learn more here.

Our Expertise. We understand The Science of Silence. Our surveyors are trained by experts at the Institute of Acoustics. That wisdom goes into every aspect of our service – the initial survey – the pre-installation visit – and the way our team approaches the installation itself.

Every one of our soundproof casement windows is bespoke

Whether you’re a homeowner, a hotelier or an architect, the specific casement windows we’ll create for you will be unique. That’s because, at the outset we don’t just measure the space, we measure the noise. We take into account different logistical factors and also your aesthetic choices.

See which of these statements is the closest fit for you.

“I’m keen to replace like with like… casement with casement.”

“There’s a planning permission issue; I can’t touch the existing windows.”

“I want to know what’ll fit best with this house and also with my refurb ideas.”

“It’s a new build – so I’m open to exploring the very best options.”

Whichever the case, we’re here to talk you through your choices.  Also – see the three scenarios below.

So why choose our casement windows?

The quality and the ‘fit’ of the products themselves. It’s not just the individual materials or the design process that set our windows apart; it’s also the way our designs are based on an in-depth understanding of specific individual needs.

The expertise that underpins our process. From the initial survey to the point of installation, we offer end-to-end expertise from a team that’s been trained at the Institute of Acoustics.

The range of options we offer.  Each of our window styles was created to suit one of the five main traditions of architecture throughout period Great Britain. (These include Contemporary flush, Conventional flush, Cottage flush, Deco and Tilt-turn.)

All the advantages of hardwood timber. With over two and a half times the lifespan of a plastic window, our hardwood timber frames are extremely durable.  Weather-resistant, they will never warp; they are also highly energy-efficient, easy to repair, easy to be coloured and completely biodegradable.

With our casement windows, three different scenarios

Typically, we create new casement windows for one of the following scenarios.  Understanding which of these scenarios you fall into will help our initial conversation.

  • ‘like for like’ replacement: This is where existing casement windows are replaced by bespoke noise reduction casement windows.
  • ‘high performance’ replacement: Where a high noise reduction is sought, each casement window can be replaced by a high-performance window or a soundproof sash window.
  • A secondary window: If it’s not possible to ‘touch’ the existing casement window – often this will be down to conservation issues, or a landlord’s specifications – then we can look at installing a secondary window.

Hear the difference between a standard window and our Silent Window:

Did you know?

Casement windows were once the height of sophistication with their finely detailed lattices and Gothic arches.  Today they are often seen as a more contemporary option.

Even our flush casement is equipped with double weather seals making it as storm-proof as leap casements.

How much noise reduction can you achieve with casement windows?

By far the best selling Casement Window in London is our 40dB Silent Casement. By comparison, the single glazed casement windows they typically replace are only capable of a noise reduction of around 25dB. Furthermore, we are now working on the 45dB model, which is in its final stages of testing.

Step 1 - Initial Enquiry

Before contacting us, please make sure you have certain details to hand. These include: the property location and type (especially if it’s a listed building or in a conservation area), the details of your problem and the kind of windows and glazing you currently have. We will make sure we have enough information to plan an effective initial visit.

For more details of Our Process please see Our Process Explained

Step 2 - Initial Visit (Noise Assessment & Pricing Survey)

An acoustic specialist will talk you through your best options and – using a NTi XL2 Acoustic Analyser – give you an immediate idea of the different noise levels, and advise you on your best options. By agreeing to a Initial Visit there is no obligation to commit to our service; this is an opportunity to understand your needs more clearly.

For more details of Our Process please see Our Process Explained

Step 3 – Quotation & Noise Report

Based on the survey completed during the Initial Visit, our team will email a full costing within 72 hours. We will also provide a valuable Noise Report which explores our problem analysis, the level of noise pollution and our suggested solution. Within another 48 hours, we will follow up with a courtesy call, to ensure everything is clear.

For more details of Our Process please see Our Process Explained

Step 4 - Installation Survey

Once you’ve chosen to proceed with us and paid an initial deposit, we’ll arrange for senior surveyors to visit. By taking accurate ‘to the millimetre’ measurements, we can assess the best method of installation. We’ll also confirm your various aesthetic preferences (eg – which timber, paint colour and ironmongery), and will then pass your order to our factory.

For more details of Our Process please see Our Process Explained

Step 5 - Manufacture Updates

The manufacturing process takes approximately ten weeks.  Every three weeks our customer service team will give you an update so you know how your windows are progressing.

For more details of Our Process please see Our Process Explained

Step 6 - Installation

Two weeks in advance, we’ll provide you with an installation date. For the installation we use an acoustic foam to enhance the noise reduction. At no point will we leave the property unprotected or exposed; if one window comes out, another goes in. The entire installation will be overseen by a single project manager.

For more details of Our Process please see Our Process Explained

Step 7 - Follow Up

One week after the installation, we will follow up with a courtesy call. This to make sure that everything is to your satisfaction, and to answer any questions you have about making the most of your new windows or doors.
