Acoustic Ratings

We understand that people can be suspicious of claims made by manufacturers. That’s why all Rose Collection sash windows are independently tested for thermal efficiency, permeability, security and acoustic performance. Independent third-party testing gives you an unbiased appraisal of the performance of our products, achieved through rigorous processes designed by industry engineering professionals.

In the case of acoustic performance, all our testing is done by BlueSky
Certification, a UKAS accredited organisation. So the figures we give you don’t come from us—they come from independently controlled test results.

Have a look at the BlueSky Certification results below. With any of the Rose Collection options, the inside of your home will be quieter and calmer.

Creating a more peaceful living environment

A Rose Collection window provides great acoustic performance as standard; on average it will block around 33dB of outside noise.

To put that into context, if you live near to a busy road or in a noisy urban location, you can expect external noise levels to be around 60 to 70dB. Reducing that noise by 33dB brings it down to less than 40dB—well within recommended guidelines.

For even better performance, we offer a range of acoustic glazing upgrades that can further reduce noise by up to 15% (up to 38dB in total) - perfect for homes in particularly noisy locations. Acoustic laminated glass is an option on all our windows. This glass includes a special 0.8mm membrane specifically designed to dampen sound. Installed alongside standard 4mm glass in a double-glazed unit, the combination of different glass thicknesses and acoustic membrane serve to disrupt, absorb and reflect sound waves. The result? Less sound can pass through the glass and into your home.

Designed with noise—and you—in mind

All our windows are designed with noise reduction in mind, as well as thermal efficiency, security and—of course—great aesthetics and low maintenance.

Every detail, from the frame and sash profiles, gaskets, brushpiles and glass, has a part to play in reducing the noise that can come through a closed window.

The World Health Organisation estimates that sustained exposure to more than 40dB is above healthy levels, while noise of 70dB means there’s a 30% chance of being woken up when you’re asleep. The standard 33dB noise reduction offered by Rose Collection sash windows is more than enough to ensure that your home falls below those levels.

The importance of noise reduction

For many of us, noise reduction can be just as important as thermal efficiency; a quiet, peaceful, relaxing place to unwind and escape the chaos of modern life is essential in today’s hectic society. Upgrading to Rose Collection sash windows can make a real difference to both your home and your standard of living.

Have a look at the BlueSky Certification results below and watch the video footage of the acoustic testing taking place to fully understand the significance of acoustic glazing. With any of the Rose Collection options, the inside of your home will be quieter and calmer.

When manufacturing our sash windows, we always go the extra mile to ensure the highest performance. With Rose Collection sash windows, you could realistically limit noise inside your home to below 20 decibels. This is equal to the sound of rustling leaves or whispered voices – in short, a quiet and tranquil living area where you can relax and unwind.
