It will most likely help however there are some potential pitfalls. A number of other considerations also have to be carefully assessed, including;
- Vents in the wall providing a simple entry point for noise.
- The gap between the roof and the ceiling above the external walls which allows noise into the ceiling space.
It’s common also, especially in domestic applications, for the windows and doors not to be sealed adequately to the building frame allowing noise to easily penetrate. Gaps and air leakage through existing window frames will permit significant noise penetration. All these issues need to be addressed if you are going to achieve maximum value out of the noise reduction properties of the glass.
