High Performance Windows

If you’re looking for the very best way to soundproof a property, our most powerful bespoke noise reduction timber windows can achieve a dramatic decrease of decibels, far, far greater than that possible with ‘regular’ double glazing. We’re talking up to 51dB. (Scroll down this page to hear what that sounds like.)

It might seem obvious what our ‘high performance’ windows are.  As their name suggests, they are our ‘top-of-the-range’ windows, designed to give you the most significant drop in decibels.

What is less obvious is whether or not they are the best fit for your needs. We support you to make that decision on our 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 51dB. 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 high performance windows is bespoke

Whether you’re a homeowner, a hotelier or an architect, the specific high performance 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.

“The level of noise is significant; I need a top of the range product.”

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

“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 high performance windows?

  • The quality and the ‘fit’ of the products themselves. It’s not just the individuals 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 end-to-end support of experts. From the initial survey to the point of installation, we offer a continuum of expertise from a team that’s been trained by experts from the Institute of Acoustics.
  • All the advantages of hardwood timber. Lasting between 60 and 80 years, they have over two and a half times the life-span of a plastic window. Weather-resistant, our hardwood timber frames will never warp. In addition, they are energy-efficient, easy to repair, completely biodegradable, and very easy to be coloured.

With our high performance windows,  three different scenarios

Typically, we create new high performance windows for one of these scenarios. Understanding these will help our initial conversation.

  • ‘high performance’ replacement: Where a high noise reduction is sought, and where each sash or casement window can be replaced by a high performance window.
  • A secondary window: If it’s not available to ‘touch’ the existing window – typically because of conservation issues, or a landlord’s specifications – then we can look at installing a secondary window.
  • ‘high performance’ new build: Where a new development warrants the very highest levels of noise reduction, insulation and security.

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

Did you know?

Our High Performance windows can be installed as secondary windows –  not only in listed buildings, but also in any other property, where you want to improve the soundproofing capability of your existing windows.

Can High Performance windows replace Sash Windows?

Yes, they can… as long as you don’t live in a conservation area where planning permission for this would be unlikely. We can even design our High Performance windows in such a way that they mimic the design of your existing sash windows, and so fit perfectly with the look and feel of your property.

We’ll measure the noise levels in different rooms in the property using a specialist noise analyser.

We’ll talk you through your options and the various logistic and aesthetic factors to consider.

We’ll ensure we have a thorough understanding of exactly what you need. (It may vary from the front to the back of the property.)

We will only recommend our own windows if they’re suitable and if we feel you would be delighted with the results.

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.
