High Performance Secondary Casement Windows

Perhaps you’re in the heart of the inner city, trains to the left of you, cars to the right. People trawling the streets beneath you all hours of the day. Or maybe you’re directly under a flight path, suffering the screech of soaring planes from morning to night. Whatever the reason, these high performance secondary windows are the ultimate solution.

By placing a secondary glazing casement window within your existing window frame, these products are designed for those dealing with severe noise pollution. Working in conjunction with your standard double glazing units, which tend to offer a ~29 dB noise reduction, these unit add an additional ~51 dB, giving you a total of 80 dB noise reduction. To put this into perspective, this will turn that jackhammer outside of your home to a quiet whisper in a library.

How High Performance Secondary Windows Works

Noise travels as a pressure wave through the air to reach your ears. By distorting this wave, and dissipating its energy, we can prevent it ever reaching you. High performance secondary windows work in combination with your current windows in order to make it as hard as possible to penetrate your home.

It does this by playing with the ‘natural frequency’ of noise pollution. By using glass of a certain thicknesses, these windows disrupt the wavelength of the sound, causing it to be distorted and lose energy.

The Glass

The glazing used in these units is an energy saving 4mm clear E-glass, with a 16mm argon-filled cavity. Optimal for high noise complaint areas. Read More About Sound Diffusion.

Tilt & Turn Mechanism

Featuring a ‘tilt and turn’ system, the internal mechanism allows you to open the window however you like; from the top, bottom, left or right. Creating a total vacuum when closed, this not only prevents any draughts or heat loss, but further prevents noise entering.

Triple Layered Timber

Constructed with triple layered pine timber, these secondary glazing units are not only designed to prevent swelling of the frames, but also to help dissipate soundwaves.

REPLACEMENT NOISE REDUCTION GLASS

On the cheap end of the spectrum, the glazing inside your existing window can be replaced with a high performance noise reduction glass. However, modern soundproof glazing can often weigh as much as 4 times your original glazing, causing long-term structural issues.
