Soundproof Imitation Sash Windows (mock sash windows)
Combining the appearance of sash with the functionality of modern casement, these imitation sash windows deliver superior reductions in noise of up to 51dB in the triple glazed option. This is the same level achieved by installing noise reduction sash as well as acoustic secondary glazing (with 250mm cavity).
Mock Sash Window Design
Often found in Georgian and Victorian properties, sash windows are so-called for their movable ‘sashes’, often separated by glazing bars. Traditionally opened by sliding a panel up or down, our mock sash windows look just like the originals but are installed with a tilt and turn system instead.
This means you can open our mock sashes inwards 90° from the side, or tilt them from the top or bottom for effective ventilation.
How The Sash Look Is Achieved
For the authentic heritage look, all of our imitation sash windows come with Ovolo mouldings as standard.
Mimicking the meeting rail of traditional sash windows, our imitations appear to be two separate sashes.
Whilst many imitation sash windows are installed on the outer frame, our range are installed recessed behind the frame to give the perceived ‘depth’ of sash.
Our mock sash windows avoid the problems inherent to soundproofing traditional sash. There is no need for seals between the panes, and no internal mechanism to act like an acoustic chamber. Instead, these windows close flush, offering superior noise reduction coefficients.
“We live in Clapham North, right under the Heathrow flight path. We acquired our house; a classic Victorian Terraced house. It had the classic PVC double glazed sash windows (10 years old, average quality but not great). Noise level from plane was significant when jumbo jets would fly over, especially at 5.30AM. We opted for a triple glazed non sash option with different glass thicknesses (high performance, but looking similar), and it has completely solved the problem. We have very large bay windows, so there was a lot of window exposure for sound to come through.”
Finished in Style
We know that when it comes to your home only the best will do. That’s why our mock sashes can be fully customised to suit your property.
Whether you want a curved frame, or a custom RAL paint job, all of our windows are bespoke and made to order.
You can choose to have just the one glazing bar, or as many as you want in keeping with your existing windows.
To complete the look, we offer a range of traditional accessories and ironmongery options for you to choose from.
It’s not just sound that these windows keep out, but the cold too. The glazing has a u-value of up to 0.6 W/m²K, meaning that our High Performance Tilt & Turn Windows are A+ rated.
Our ultra range comes with a variety of options depending upon the severity of your noise problem:
- 40dB (68mm frame)
- 46dB (78mm frame)
- 50dB (88mm frame)
- 51dB (88mm frame)
