What thickness of pipe insulation do I need?

As a rule of thumb – thicker insulation = less heat loss from pipes and greater protection from freezing temperatures. For outdoor pipework, we recommend a minimum insulation thickness of 19mm.

Does pipe insulation prevent freezing?

Insulation can help keep a pipe closer to the temperature of the water inside the pipe, but it does not add heat to the pipe and will not prevent freezing if the pipe is exposed to prolonged freezing temperatures.

Is foam pipe insulation better than fiberglass?

Pipe insulation materials, such as fiberglass, are best for pipes exposed to hot temperatures, while foam and rubber are a better fit for cold water pipe lines but work in hot pipes as well.

How do you keep outdoor water pipes from freezing?

Prevent outdoor pipes from freezing by insulating outdoor hose bibs and water supply lines. Pipe insulation contains a slit that makes it easy to slide over water pipes and supply lines, and bib covers shield the spigot from winter weather.

Does PEX insulation better than copper?

PEX can also insulate water better than metal, which means hot water will lose less heat than it would in copper. PEX piping also doesn’t suffer from scale buildup or chlorine damage the way copper can, and it can resist freezing conditions that would crack copper.

Will pipes freeze in unheated garage?

The pipes most at risk are those in unheated interior spaces such as basements, attics, and garages. But even pipes running through cabinets or exterior walls can freeze. The good news is there are some simple things you can do to keep your water running and your house dry.

Will PVC pipe crack if frozen?

A freeze event in a plastic water piping system is a complex phenomenon. PVC and CPVC pipe filled with water, sealed and placed in a freezing environment typically will not crack. The pipes will expand to absorb the net volumetric expansion of ice.

Should I insulate cold water pipes?

There are several reasons you’ll want to insulate your cold water pipes if you haven’t already. First, insulating cold water pipes helps protect against freezing. Second, because cold water pipes absorb heat, during the winter they will draw heat from the space around them, assuming this space is insulated.
