Insulating PEX is a seriously worthwhile investment. It protects pipes from the elements, cuts down on energy consumption, and keeps water temperatures consistent. A little insulation goes a long way!
Does PEX need to be insulated?
We recommend insulating PEX in environments where the temperature may cause the pipes to freeze. Pre-insulated PEX also helps keep water temperatures even and reduces energy costs. So while it’s not strictly necessary, it’s always a good idea.
How do I insulate PEX pipe?
Measure the length of the pipe and cut the insulation to size. Make sure the insulation fits snugly around the pipe. If you're insulating PEX tubing that’s already installed, you can use split insulation, which wraps around the pipe and can be sealed with adhesive or tape.
What is the best insulation for PEX pipe?
The best insulation for PEX typically includes foam insulation sleeves made from polyethylene or neoprene foam. These materials offer a good balance of thermal protection, moisture resistance, and ease of installation. Your choice of insulation or pre-insulated PEX tubing may also depend on space constraints and climate.
Does PEX pipe withstand freezing?
PEX has a certain amount of flexibility, which can allow it to expand if water inside the pipe begins to freeze. But PEX alone isn’t completely freeze-proof. For safer pipes in cold climates, we recommend insulation.
