Old doors and windows can be a source of sound in your home, but they don’t have to be. The better the quality of the product you use, the more efficient it will be at keeping sound out. If you want to soundproof old doors and windows, there are many ways to do it:
Determine what types of noise you want to block and the windows and doors in question
For example, if your job site is next to a highway, it’s likely that noise from passing vehicles will be a problem. If the window in question faces south or west, wind noise may also be a factor.
Consider the type of doors and windows in question, as well as their location within the structure. For example, single-pane windows usually can’t be closed because they lack insulation; double-pane windows are better options because they have more insulating layers between panes. If there’s an existing door or window that doesn’t meet current building codes for energy efficiency or durability (such as wood), consider replacing it with something more suitable for your needs.
Adjust existing panels
If your old door or window frame is in good shape and doesn’t need too much work, you may be able to adjust it by simply adding some felt strips around its edges. This can help reduce gaps around the edges that can allow air to escape when you open the door or window.
Install new panels
If your door or window frame needs extensive work and won’t fit into existing openings, consider replacing it with a new one. New frames are available that are specifically designed for soundproofing purposes.
You can also choose to replace old windows with energy efficient ones that will not only keep out noise but also save money in the long run by reducing cooling costs. Replacement windows and doors will solve the problem if the old ones are no longer functional and are beyond repair.
Use acoustical seal
If you want to soundproof old doors and windows but don’t have the cash to buy a new one, consider getting an acoustical seal. This will keep sound out of your house by blocking it out rather than letting it in. It’s not a permanent solution, though, so you’ll need to replace it periodically with something else (like insulation).
Use acoustic foam
If you want less of an investment than an acoustical seal but don’t want to replace your doors and windows all over again every few years, consider investing in acoustic foam instead. This is a more temporary solution that will also keep noise out of your house for a short time before needing replacement again.
