What to use to insulate outside pipes?

Insulation Methods and Materials

  1. Duct tape.
  2. Expanding spray foam.
  3. Foam caulk rope.
  4. Insulation of choice (pipe sleeve, pipe-wrap, outdoor faucet cover)

Can pipe insulation be used outside?

You can insulate all pipes in exterior walls with wall insulation. Pre-slit foam pipe sleeves are a simple way to cover long straight lines. Gaps where pipes penetrate walls can be insulated with foam insulation products that expand when applied to fill the gap or foam caulk rope.

Can fiberglass pipe insulation be used outside?

While not intended for outdoor use, preformed fiberglass pipe insulation with conventional all service jacketing (ASJ) has an exposed kraft paper surface and self-sealing lap (SSL) joints.

What to wrap outdoor pipes with?

Wrap pipes with heat tape or thermostatically controlled heat cables. Be sure to follow all manufacturers’ installation and operation instructions. Seal leaks that allow cold air inside, near where pipes are located (i.e. around electrical wiring, dryer vents, other pipes), with caulk or insulation.

How do you cover outside pipes to prevent freezing?

To keep exterior pipes from freezing, protect them with polyethylene pipe insulation and duct tape. In your home, turn the heat on until the weather warms up and keep your cabinet doors open underneath your sink. Leave your sinks on so that a thin trickle of water comes out and keeps the pipes from freezing.

How do you insulate water pipes in exterior walls?

Use caulk or foam to seal any holes where the pipes penetrate walls, floors, ceilings, or framing. If pipes run through exterior wall cavities, insulate the wall cavity just as you would the other cavities if using blown cellulose, fiberglass, or spray foam, which will easily fill in the space behind the pipes.

Is pipe insulation waterproof?

Those familiar with pipe insulation at industrial and electric power facilities know that insulation all too often becomes wet, primarily from precipitation. Yet in most applications, the insulation is covered with a protective jacket, usually one that can withstand weather such as rain, wind, and sunlight.
