SOUNDPROOF CASEMENT WINDOWS
The elegance of casement windows was once the height of sophistication, highly desired for their finely detailed lattices and gothic arches. Now with our soundproof casement windows, you get all the style of yesteryear along with the heightened noise reduction and thermal efficiency values of modern design.
The Science of Soundproof Casement
Available in our Soundpoof, Soundproof+ and Ultra range, we can offer up to 53dB noise reduction values, with designs customised to suit your home.
Our soundproof casement windows stop noise entering your home by distorting the wave and dissipating its energy. With high performance seals, specialist acoustic glazing and an updated design, our products are top of the line, providing the greatest reductions available on the market.
Noise Reduction Glass
All sounds reverberate at different frequencies. In order to dampen them, you need to confuse the wave pattern so that it dissipates rather than entering your home.
By using different thicknesses of glass, according to your specific noise source, soundproof casement windows break up the soundwave, stopping it dead in its tracks.
MODERN SEALANTS
These windows are finished with the best sealants available, closing any gaps and preventing any draughts or annoying noises entering your home.
LOCKS & HANDLES
By using the best lock and handle systems available, you can keep your home safe, secure and soundproofed.
