TRC Contracts has announced strong results from its most recent acoustic performance testing, demonstrating the company’s continued commitment to delivering specification-led window and door solutions for demanding projects.
The results, obtained through rigorous independent laboratory testing, confirm TRC’s capability to meet stringent sound reduction requirements across its product range – a critical consideration for architects, consultants and contractors working on residential and commercial developments in London, Manchester, Liverpool and other major urban centres.
In addition to these results, TRC is placing significant focus on its new product selector tool – a major step forward in how architects and specifiers can access, compare and specify acoustically tested windows and doors with speed and confidence. This digital tool is now a primary resource for turning verified acoustic data into practical specifications.

The testing underlines an important milestone for the company: TRC is now the first sash window manufacturer able to offer such an extensive range of independently tested products across different glazing specifications, including Slimlite, vacuum, double and triple glazed options.
The importance of acoustic performance in modern construction
Sound insulation has become a fundamental factor in determining quality of life within both residential and commercial buildings. High levels of noise within a building can quickly lead to a challenging – even unbearable – living or working environment, while effective soundproofing significantly improves comfort, relaxation and wellbeing.
Beyond occupant satisfaction, acoustic performance is a major component of building regulations. If you’re involved in new build or renovation projects, it’s safe to assume that sound testing will be required by law. For architects and specifiers, this means selecting fenestration solutions that can reliably deliver the necessary performance levels while meeting aesthetic and conservation requirements.
This challenge is particularly acute on heritage projects, where planning constraints often necessitate traditional window designs. TRC specialises in offering compliant products alongside professional advice for architects working on both heritage and new build projects where sound insulation cannot be compromised.
The testing process and methodology
TRC commissioned comprehensive acoustic testing at KP Acoustics Research Labs Ltd, an independent UKAS-accredited facility. The testing followed strict international standards:
• Sound insulation laboratory testing according to ISO 10140-2: 2021
• Acoustic rating according to ISO 717-1: 2020
These internationally recognised protocols ensure results are reliable, comparable and acceptable to building control bodies across the UK.
To further strengthen TRC’s technical knowledge and customer advisory capabilities, Sales Manager Zach Hughes and Sales Advisor Wes Southcombe attended the testing sessions in person. This hands-on involvement ensures TRC’s team can provide informed guidance when helping clients select the right solution to achieve required acoustic performance levels.
The testing programme evaluated TRC’s core product range across multiple glazing configurations, providing architects with detailed performance data for specification purposes.
Demonstrating acoustic excellence in action
To give specifiers and clients a closer look at the process behind the results, TRC has produced a video showcasing the acoustic testing carried out at KP Acoustics Research Labs Ltd. The footage captures the rigorous procedures followed under ISO 10140-2: 2021 and ISO 717-1: 2020, reinforcing the credibility of the independently verified performance figures.
The video highlights how TRC’s products perform under controlled laboratory conditions, demonstrating why we now lead the market with one of the most comprehensively tested traditional window ranges. From vacuum glazing to triple glazed sash units, the testing visuals provide clear evidence of the engineering detail and product integrity behind the impressive Rw ratings achieved.
Including this video reflects our commitment to complete transparency and to supplying the highest standard products for both heritage and new build projects. It also gives architects, consultants and contractors added confidence when selecting solutions where acoustic performance is non-negotiable.

Why acoustic testing matters for specification
Independent laboratory testing provides architects and specifiers with verified performance data that can be relied upon throughout the specification process. Unlike generic industry estimates or untested product claims, these results offer:
- – Confidence in meeting building regulation requirements
- – Clear evidence for planning applications
- – Reliable data for acoustic consultant calculations
- – Documentation for building control approval
For projects in noise-sensitive locations – near railway lines, busy roads, flight paths or in dense urban environments – verified acoustic performance data is essential. The testing also allows meaningful comparison between different glazing options and window configurations.
Selecting the right acoustic solution for your project
The range of tested products allows TRC to support different project scenarios. A conservation officer may require slimline glazing profiles that suit a Georgian property, while building regulations demand specific acoustic performance levels. TRC’s vacuum glazed traditional windows address precisely this challenge.
Alternatively, new build developments in city centre locations may prioritise maximum acoustic performance within modern building envelopes. The Traditional Box Sash Window’s Rw 39dB rating delivers exceptional sound reduction while maintaining the architectural character that planning departments and clients increasingly favour.
TRC’s technical team, equipped with first-hand knowledge from attending the acoustic testing, can guide you through the selection process. They understand how different glazing specifications, frame designs and installation details affect overall acoustic performance.
