Beer Line & Trunk Line Insulation
Any exposed beer line run — through a warm ceiling cavity, along an uninsulated wall, or across an outdoor patio — starts picking up heat before it reaches the faucet. Insulation is the cheap fix that keeps a properly-chilled beer cold for the last few feet of the journey instead of losing the fight right at the finish line.
What We Carry
- Foam sleeve insulation — slides over exposed beer line or trunk bundle for continuous coverage along a run
- Insulating wrap tape — for wrapping irregular sections, joints, or spots a foam sleeve can't reach
Where Insulation Matters Most
- Lines running through a warm ceiling space, kitchen wall, or unconditioned area
- Any exposed section of trunk line between the cooler and the tower that isn't already inside an insulated bundle
- Outdoor and patio bar installations where lines are exposed to ambient temperature swings
Insulation supplements a glycol system — it doesn't replace one. On a long run, glycol keeps the beer cold; insulation keeps outside heat from working against it.
Beer Line Insulation FAQ
Do I need insulation if I already have a glycol system?
Yes, for any exposed section not already inside the insulated trunk bundle — insulation and glycol do different jobs. Glycol actively cools the line; insulation just slows down how fast outside heat can work against that cooling. Skipping insulation on an exposed run makes your glycol system work harder than it needs to.
Foam sleeve or wrap tape — which should I use?
Foam sleeve is faster and gives more consistent coverage for a straight run of exposed line. Wrap tape is better for irregular shapes, joints, or patching a spot a sleeve doesn't fit — many installs use both.
