Do metal pipes need to be insulated?
While PEX is less at risk of freezing than copper (plastic doesn’t conduct cold the way metal does), both types of pipes need to be protected if they’re exposed to the weather. You don’t, however, have to insulate gas pipes. These are made of galvanized metal, which typically appears dull and heavy.
What kind of pipes are used for hot and cold water?

What kind of glue is used for cold water pipes?
In homes plumbed with first-generation plastics, the cold water lines are often PVC, with CPVC used for hot water lines. PVC connections are made by using a primer that softens the PVC and then applying PVC glue that melts the joints and pipe together.
Which is more durable PEx or copper water pipes?
With good resistance to both hot and cold temperatures, PEX is commonly used for both hot and cold water lines in homes, and for hydronic heating systems (such as radiant under-floor systems). PEX is considered more durable than copper, with a likely lifespan of more than 50 years.

What do Plumbers use to secure water lines?
Stabilize loose water-supply lines to prevent banging. During home construction, the plumber uses U-shaped pipe straps to fasten water-supply lines to wooden joists or studs with screws. If the straps aren’t tight enough—or if a few straps are missing—the pipes can knock around and create noise.
