    Insulation
In summary, the conversation discusses the best way to support and insulate a run of PEX water line. The suggested method is to put the insulation over the pipe before clipping it, similar to how it would be done for copper pipes. It is also mentioned that copper and steel pipes do not need clamping over short runs or protection from UV light, so insulation can be done in the same way as for copper pipes.

TL;DR Summary
How should we insulate PEX that also needs to be held with clips?
If a run of PEX water line needs to be periodically supported with pipe clips and also insulated, what's a good way to do this? - put the insulation over the pipe before clipping it and use clips for large diameter pipes?

Is your question specific to PEX? Why wouldn’t you insulate in an identical way as you would copper pipes?

The question is specific to PEX in the sense that PEX is what I'm using. Copper and steel pipes don't need to be clamped over short runs. Also, copper and steel pipes don't need a covering to protect them from UV light.

So, clamping distances aside, there’s no reason to insulate any differently than copper pipe. Insulate first and hang on J-hooks or notch at the joints and glue pieces of insulation at the joints, just like copper.
Is there any type of insulation for any pipe that doesn’t also protect against UV?
 

Related to PEX - using both insulation and clips

1. What is PEX?

PEX (cross-linked polyethylene) is a type of plastic tubing used in plumbing and heating systems. It is flexible, durable, and resistant to corrosion and chemicals.

2. Why is insulation important for PEX?

Insulation helps to protect PEX from extreme temperatures and prevents it from freezing or bursting. It also helps to maintain the temperature of the water inside the tubing, making it more energy-efficient.

3. How does PEX insulation work?

PEX insulation is typically made of foam or rubber materials and is designed to wrap around the tubing. It creates a barrier between the PEX and the surrounding environment, reducing heat loss or gain and preventing damage to the tubing.

4. What are PEX clips used for?

PEX clips are used to secure PEX tubing to a surface, such as a wall or floor. They help to keep the tubing in place and prevent it from shifting or moving, which can cause damage to the connections and fittings.

5. How do I know which PEX clips to use?

The type of PEX clips you need will depend on the size and type of PEX tubing you are using, as well as the surface you are attaching it to. It is important to choose clips that are specifically designed for PEX and follow the manufacturer's recommendations for proper installation.
