Click For Summary
For supporting and insulating PEX water lines, it is recommended to insulate the pipe before securing it with clips. This approach is similar to the insulation methods used for copper pipes, despite PEX's unique characteristics, such as the need for UV protection. While copper and steel pipes can be supported over short runs without clamps, PEX requires periodic support with pipe clips. The insulation should be applied first, and J-hooks can be used for hanging, with notched joints glued for added stability. Additionally, there is a question regarding whether any insulation type provides UV protection, highlighting the importance of considering UV exposure when selecting insulation materials for PEX.

TL;DR
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?
 

Thread 'How do I fix a hedgehog enclosure that keeps getting too humid'

Hey folks! So I’m kinda losing my mind over my hedgie’s setup lately. No matter what I do, the enclosure keeps getting super humid and it’s starting to smell funky. I clean it, switch bedding, crack the window, the whole nine yards… but it still ends up damp and I’m worried it’s gonna mess with my little dude’s health. I’m starting to feel like I’m doing something wrong even though I’m trying so hard. Has anyone dealt with this before? Any tips, hacks, gear recs… literally anything would...
