A decade since it pioneered the first zero carbon 0.8 U-value PVCu window for the mainstream UK market, CMS Window Systems is first again, this time with the launch of the country’s first Quiet Mark approved acoustic PVCu window.

Its development marks a step change in how noise issues for homeowners and tenants can be effectively tackled through window and door design, manufacture and installation. Building on the current superior performance of the CMS window range to add a noise barrier, the CMS Silent-Therm Window prevents everyday noises outside from disturbing the peace and quiet within. The result is a sound insulating window delivering A-rated energy performance, compliance with the enhanced security requirements of Secured by Design and significantly improved furniture ‘fade control’.

Developed in conjunction with leading sealed unit manufacturer GLASSOLUTIONS and independently tested at Aerotech Laboratories, the CMS Silent-Therm Window significantly outperforms standard windows in terms of its ability to reduce external sounds, such as traffic and barking dogs. It offers huge potential to the millions of people who suffer the devastating effects of unwanted noise, especially at night: research shows that people whose sleep is disturbed by noise are at greater risk of developing a variety of serious health conditions, including heart disease, diabetes, strokes and depression.

Key to the CMS Silent-Therm Window is a smart window design which utilises the specialist acoustic glass from Saint-Gobain, Stadip Silence, plus the market leading low-e glass Planitherm Total+ combined with a Sheerframe energy efficient PVCu frame. These windows are able to reduce sound travel into a room by 5db, whilst at the same time optimising heat insulation and solar gain.

Such is the effectiveness of the window’s noise control capability that it has been approved under the Quiet Mark scheme – the internationally recognised certification of the UK Noise Abatement Society. In becoming approved, CMS joins some of the UK’s best-known brands in this rapidly emerging scheme, including Dyson, John Lewis and Virgin Atlantic.

The CMS Silent-Therm Window is available in six window types to suit all types of PVCu window application, including casement, reversible, and tilt and turn. These are all created using Sheerframe PVCu window profiles, all of which are 100% calcium organic stabilised and fully recyclable, UK-made and provide superior thermal insulation thanks to an advanced multi-chamber profile design.

Andy Kerr, Managing Director of CMS Window Systems says: “Noise is a huge issue for so many householders, but until now there has been no approved window specification to help building professionals, architects and homeowners properly address the issue. We’ve changed that with the launch of our acoustic thermal window: by utilising the best technology and investing in Quiet Mark approval we aim to give total confidence that the window will enhance acoustic insulation in the home.”

Employing around 250 people at its 15-acre main manufacturing base and HQ near Glasgow, plus its facilities in Fife, CMS Window Systems is one of Scotland’s fastest growing manufacturing businesses. In addition to its range of PVCu windows and doors, the company also designs, manufactures and installs aluminium and timber composite systems for commercial construction projects as well as offering total building envelope solutions through the installation of external wall insulation (EWI) and cladding.
