Use foam rubber or fiberglass sleeves to help decrease the chances of freezing. Insulation can help keep the pipes closer to the temperature of the water inside the pipe, but it does not add extra heat to the pipe and unfortunately will not prevent freezing if the pipe is exposed to prolonged freezing temperatures.
Foam pipe sleeves, commonly made from flexible, lightweight foam like polyethylene or rubber, are a user-friendly insulation option for outdoor water pipes. Designed to fit snugly, they provide an effective thermal barrier, helping to maintain water temperature and reduce the risk of freezing.
The thickness of pipe insulation for most common residential cold water pipes is 1/2" thick. There is usually no additional benefit of adding more than 1/2" thick fiberglass or rubber pipe insulation to cold water piping.
With the right foam insulation material, sufficient thickness, and proper installation, foam pipe insulation can: Reduce heat loss by up to 80% Decrease energy costs by 10-20% Lower surface temperatures by 15-20°F.
If insulation is not an option, consider wrapping them with rags, newspapers, trash bags, plastic foam, or bubble wrap.
Polyethylene foam is considered to be the most efficient form of pipe insulation. We use it often here at Boss Plumbing, since it can be easily installed to any kind of pipe. It also has the highest R-value, meaning it will be the best pipe insulation to keep your pipes warm.
Once the insulation is in place, ensure it's secured properly. Whether using clamps, adhesives, or ties, a snug fit ensures longevity and sustained performance. Consider using a vapour barrier for cold water pipes, especially in humid conditions.
Pipes that freeze most frequently are: Pipes that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, and water sprinkler lines.
Set faucets to a small, steady drip rather than a stream to conserve water while preventing freezing. Drip the faucet farthest from your home's main water valve. “You don't have to drip them all—one or two is fine,” Sperlich told USA TODAY.
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.
Here you go: The best low-temperature insulation: Cellular plastic or foam rubber. The best moderate-temperature insulation: Glass fiber. The best high-temperature insulation: Preformed cement, refractory materials or ceramic fiber blankets.
Generally, houses in northern climates are built with the water pipes located on the inside of the building insulation, which protects the pipes from subfreezing weather.
One of the top recommendations for cold climates is premium injection foam insulation for the walls. Injection foam is injected into wall cavities, expanding to fill every gap, creating a seamless, airtight barrier.
While both types provide insulation, R30 is the better option for maximizing energy savings in areas where heat loss or gain is a major concern. For example, R19 may suffice for interior walls, but R30 is more appropriate for exterior-facing attics or floors.
Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).
R38 insulation provides higher thermal resistance than R30, but the additional energy savings may not always justify the increased cost: R38 offers 26% more thermal resistance than R30. Upgrading from R30 to R38 can result in approximately 25% energy cost savings.

Insulation can help keep the pipes closer to the temperature of the water inside the pipe, but it does not add extra heat to the pipe and unfortunately will not prevent freezing if the pipe is exposed to prolonged freezing temperatures.
Fiberglass Insulation
This plastic layer is designed to trap moisture and preserve warm temperatures. As such, this material is best suited for warm water pipes, especially in colder climates. By using fiberglass pipe insulation, you can keep your pipes warm throughout the year.
As a rule of thumb - thicker insulation = less heat loss from pipes and greater protection from freezing temperatures. For outdoor pipework, we recommend a minimum insulation thickness of 19mm.
Insulate. Insulating your pipes and water tanks is one of the best ways to prevent them from freezing. You can buy inexpensive pipe lagging and tank jackets from most DIY stores and fit them yourself for free. Just make sure you check the pipe and tank measurements first.
Yes, pipes can freeze overnight if temperatures plummet drastically. Uninsulated pipes in unheated areas like attics or exterior walls are most vulnerable.
Many times, fiberglass is not adequate. Fiberglass insulation cannot and will not provide an air barrier. Conversely, spray foam can. Spray Foam is the best option to keep pipes insulated from the freezing outdoor air.
