Soundproofing Skylights…

This E-mail was written by M.N. from Murrieta, CA

I have skylights and windows in my house. Most of the noise comes through the skylight, what can I do to fix the noise problem?

This problem is much easier to fix than you might think. A skylight is obviously installed to be a light source and any acoustical fix is going to need to be as transparent as possible. Fortunately, we have a solution that most people will not notice, visually.

Our Climate Seal™ Acoustic Series Window Insert is a custom made insert or retrofit window that you are able to install yourself, very easily. The windows are built with a perimeter bellows which frame a clear, 1/4″ thick acrylic sheet. The acrylic that we use is guaranteed never to yellow, and is nearly invisible.

The Climate Seal™ Window was originally designed to be a re-usable heat retention window. The acrylic was set into a bellows to allow the air between the two windows to expand and contract as the air heated and cooled. Because of this air tight seal, we realized that there was not only an incredible market for the thermal properties of the window, but also acoustically.

The installation procedure of the windows requires some measuring and filling out a simple measurement sheet. If at all possible, a few digital photos of your window(s) will greatly help me make the measuring easy for you. The windows will either sit as a flush mount on the exterior of the window or as an in-jamb mount which sits closer to the window – or within the jamb itself. The window is made to fit as needed, and I can explain this in more detail if you would like. Please feel free to call.

I’m sure you’re thinking what everyone thinks… “How do I know these windows will work, or at least how effective will they be? And, what do they cost?” The acoustical performance of the window will be very similar (if installed correctly) to two or three layers of sheet rock placed over the window – as if the window wasn’t there. The performance is going to depend on the frequency, or type of sound that is causing you the most trouble. The low rumble of a jet is going to make it through not only the window, but the entire structure more so than traffic noise simply due to the type of energy wave that we’re dealing with.

Cost… All of these windows are custom made to your exact window size and the type of mounting that will work best for your situation. I usually ballpark these windows at around $20.00 per square foot which does not include shipping – but am happy to take sizes and measurements and draft a quote for you. The windows will actually pay themselves off in 3-5 years due to the thermal efficiency increase – which greatly helps.

    Hi Ted ; I live in California near Morro Bay. We have a busy street ( at least busy for the country ). Our home has a lot of skylights which allow considerable noise in and heat out.
    Just how easy are these windows and bellows to install?

    Where are you located ?

    Can they be installed inside the skylight wells ?

    Look forward to your response

    Hi there. I live in New Zealand and wondered if you ship internationally or whether you have contacts closer to me in either New Zealand or Australia. I live in a rural area near the sea and am mainly looking at soundproofing our two skylights to cut out wind noise.
    Thanks so much. Fiona

      Yes, we can ship internationally, that is not a problem. The cost of shipping can be quite high, of course, but we do ship internationally. We do not have any contacts or reps in New Zealand, unfortunately. If you can source the 1/4″ acrylic plastic sheets locally, we can also just send you the perimeter which creates a much smaller package for shipping and is thus more cost effective.
