Fire rated expanding foam can be used as an efficient seal against smoke and gas, providing up to 240 minutes fire rating. As well as being useful due to its excellent filling characteristics, fire rated foam has high thermal properties and provides acoustic insulation.

Is expanding foam dangerous?

Once the foam has fully expanded and dried, manufacturers say it is inert. If the chemicals are not properly mixed, they may not react fully and can remain toxic. In addition to the dangers associated with installation, these chemicals can potentially remain unreacted in the form of dust or shavings.

Is foam or rubber pipe insulation better?

The foam insulation is extremely flamable , so its not recommended to put foam insulation near your hot water heater (just to be safe) . Foam insulation also shrinks when it is put on a hot pipe, which could leave spaces in between pieces. Rubber is good for cold pipes, but is a more expensive insulation.

Which is better foam or fiberglass pipe insulation?

For heating systems I defer to Lurch77 as they operate at higher temperature.

What is the best insulation for water pipes?

You can use polyethylene pipe insulation for all other hot- and cold-water pipes, but this is rigid and requires fittings at each of the right angles of the pipe. Use fibreglass wrap or foam-and-foil wrap duct insulation for an easy fit around all other pipes and duct work.

Can you insulate around water pipes?

Spray Foam Insulation

To insulate between a single pipe and the exterior wall, you can use do-it-yourself spray foam that comes in a can, directing the spray only between the pipe and the exterior wall, and then insulating the rest of the stud space with fiberglass batts.
