Fire & Acoustic Socket Box Inserts vs Putty?

[nostos156]

Hi all,

Looking at putting in either putty or those premade fibre socket box inserts for fire rating + air leakage reasons. Just wondering if anyone has any experience and if the putty you have to mould in yourself is better than the premade fibre boxes or not.

Not seen both, but the square sheets I used, were quite easy to cut to size and mould into place. But if you can get pre sized stuff, one less thing.

Both putty and premade fibre socket box inserts can be effective in terms of providing fire rating and reducing air leakage. However, there are some differences to consider when choosing between the two.

Putty is a versatile material that can be easily molded to fill gaps and spaces around electrical boxes, pipes, cables, and other penetrations. It is typically made of a non-hardening, non-shrinking material such as silicone or intumescent materials that expand when exposed to high temperatures, helping to prevent the spread of fire and smoke. Putty can also provide good acoustic and thermal insulation, as well as resistance to moisture and chemicals. However, putty can be messy to work with, and it may not provide as much structural support or durability as a premade box.

Premade fibre socket box inserts, on the other hand, are designed to fit snugly around electrical boxes, creating a barrier against fire and air leakage. These inserts are usually made of mineral wool or other fibrous materials that have been treated with fire retardants, and they can be easily installed by simply pressing them into place around the box. Premade inserts can be more convenient to use than putty, and they may provide more consistent and reliable fire protection. However, they may not be as effective at filling irregular gaps or spaces as putty, and they may not provide the same level of acoustic or thermal insulation.
