What Are the Benefits of Soundproofing Your Sash Windows?


Better Sleep

If you or a family member has trouble sleeping because of loud street noise, outside pests or other causes, soundproofing your sash windows will help improve the sound isolation between the outside of your house and the inside, affording a better night’s sleep.

Good Health

Soundproofing your sashes doesn’t just stop annoying noises and save you from mental strain. It also helps to improve the overall health of your family as noise pollution exposes you to higher levels of carbon dioxide and other pollutants which, along with lack of sleep, cause stress, depression and heart disease.

Increased Energy Efficiency

Sash windows soundproofing helps to reduce noise from the street that may come into your home, and thus reducing energy costs. This may be done by fitting thick foam gaskets to the window frames or panes and glazing your windows with sound absorption glass.

Improved Property Value

If you want your home to be more attractive to potential buyers or renters, soundproof sash windows are a great way to offer better value. Your house will be more appealing and hold greater value when what goes on inside of it can’t be heard outside of it.

Reduced Condensation

When the temperature outside rises too high, it begins to transfer into your home – leading to condensation on the inside of your windows. Soundproofing your sash windows is a big step towards reducing the amount of condensation that is bound to occur in your home after winter.

Improved Privacy

Noises that are able to travel outside indicate a lack of privacy in the home and can suggest an unclean environment. Soundproofing your sash windows allows you to create a more private environment both inside and out.

Our Sash Windows Soundproofing Process


  • sash window

    Step 1: Initial Consultation

    Trade Timber Windows and Doors Brighton offers free, no-obligation initial consultations to determine the soundproofing requirements of your property. The initial consult will give you and our window technician the chance to talk through some of the possibilities.

    We will advise you on your options and any possible ways in which we can help. One of our experienced technicians will carry out an on-site survey, making detailed notes, so that a quotation can be prepared for you.

  • Step 2: Noise Analysis

    Trade Timber Windows and Doors Brighton carry out a noise analysis on all sash windows before we do any work on them. This is in line with the industry standards of installing soundproofing within your home. Our team will conduct a noise analysis on your building site (measuring soundproofing effectiveness).

    The noise analysis done by our experienced sound engineering engineers is a crucial process in any soundproofing project. If the source of the noise is not identified accurately, properly calculated and metered properly, then there could be unwanted side effects, false readings of reductions in noise propagation to be made and could lead to costly remedial work.

  • Step 3: Solutions Recommendation

    After tracing your main sound problems, how you would like to eliminate them and what effect this solution would have for you, we then offer you a possible solution to these problems focusing first on the area where noise is most affecting and then going through all the areas that you desire to soundproof.

    All of our recommendations will be custom-made for your individual home and based on the exact size, shape, and material of your sash windows. This allows us to make sure that the final cost of the work does not end up being more than you expected.

  • Step 4: Installation

    Our sash window soundproofing installation process starts by carefully removing your old sashes, then we’ll fit new openable/removable modern sashes using special soundproof windows designs. We then fit our acoustic seal in between your panes to block out unwanted noise.

    An insulation pad will be placed between the moving parts of the sash and the astragal, creating a buffer around the moving areas of the sash. The sash will then be refitted into their original place in the window and any excess material can then be trimmed. Finally, the window will then be screwed back into place.
