This is because installing double-glazed sash windows requires a substantial amount of work and alteration to the frame. There are retrofit options that permit homeowners to keep sash windows but still benefit from the latest noise reduction technology.
The soundproofing of sash windows can be affected by a variety of variables. For example, the construction and the material of the frame play a major role. Single-pane windows and those with poor seals offer minimal noise protection, while double glazed frames made from uPVC or timber can greatly reduce this issue. The thickness of the window glass is also crucial, as more thick glass provides more noise reduction.
In terms of the type of frame, uPVC and aluminium are both the most popular choices. Both are designed for efficiency and durability, however uPVC is slightly more energy efficient. Wooden frames are a good choice as an alternative. Hardwoods such as Accoya are extremely robust and resistant to humidity.
