What are PVC insulators?
Sometimes called simply “vinyl,” Polyvinyl Chloride (PVC) provides cables with the. ability to resist oils, acids alkalis, sunlight, heat weathering and abrasion.
Is plastic a good insulator of cold?
Insulation helps keep cold things from warming up and warm things from cooling down. Insulators do this by slowing down the loss of heat from warm things and the gaining of heat by cool things. Plastics and rubber are usually good insulators.
What material is the best electrical insulator?
Some materials such as glass, paper and PTFE, which have high resistivity, are very good electrical insulators.
Does PVC hold static electricity?
Hold the PVC pipe an inch or two away from the can and watch the attraction forces at work. Why it works: When you rub the PVC pipe on the fuzzy material, electrons build up a negative charge on the pipe. These electrons can then pull light and positively charged objects!
What is the difference between PVC conduit and PVC pipe?
PVC pipe and PVC conduit have different uses. PVC pipe is used primarily in plumbing and other pressurized systems. PVC conduit is used primarily in electrical systems. PVC pipe thus is used to carry water, while PVC conduit typically works as housing for wiring.

Ambient temperature — PVC conduit isn't permitted to be installed if the ambient temperature exceeds 50°C (122°F) [Sec. 352.12(D)].
Where is pipe insulation used?
Applications. One of the primary uses for pipe insulation is condensation control. As with any container full of liquid at below-ambient temperature, colder pipes tend to develop condensed water vapor on their exterior, an undesirable effect that can lead to corrosion and water damage.
Why pipes are insulated?
Proper insulation around pipes limits heat transfer and provides a vapor barrier against moisture, which improves the thermal efficiency of your home and saves you money. Poorly insulated pipes allow water to condense, which leaves pipes susceptible to standing water that can freeze in cold weather.
How are pipes insulated?
A common way to protect pipes is with traditional pipe wrap insulation. This type of insulation is available in many different materials, including flexible foam with rubber backing tape, foam-and-foil pipe insulation, bubble-film pipe wrap, foil-backed natural cotton, and rubber pipe insulation tape.
What are pipe insulation made of?
Three materials are most commonly used for residential plumbing insulation: fiberglass, rubber, and foam.
What is required before specifying piping material?
Above all, before specifying any piping material, a full evaluation of the system requirements in advance of making a final selection is key. Those requirements may include meeting applicable energy codes governing heat loss, as well as determining the pipe’s operating surface temperature for hot water service, and the potential for condensation for cold water service.
Can plastic pipes be used for insulation?
Some codes may afford designers the flexibility to use plastic pipes with thi cker walls at reduced levels of insulation. But, in general, code officials will require alternative designs to demonstrate parity of thermal performance with a baseline case that meets code.
Does Corzan CPVC need insulation?
For instances of system piping that is not being driven by a plumbing, mechanical or energy code (e.g., hot and cold water supply lines within conditioned buildings), insulation may not be needed, or could be reduced, because Corzan CPVC piping will remain condensation-free under most environmental conditions that would cause copper tube to sweat and drip. Water temperature can be calculated versus the dewpoint to determine the best solution.
Do you need pipe insulation for hot water?
All current model building energy codes require pipe insulation on service hot water and HVAC applications to prevent that loss. However, the codes are material-neutral; the insulation requirement is expressed in terms of minimum thickness only.
Does Corzan CPVC have thermal conductivity?
While Corzan CPVC’s lower thermal conductivity inhibits heat loss, the material alone cannot meet the minimum required thermal performance needed for code compliance. [See Facts About Insulation Requirements for Plastic Piping, a publication of the North American Insulation Manufacturers Association (NAIMA), to read more about the subject.]
Is Corzan ® CPVC Adequate for Insulating in Commercial Plumbing & Hydronic Heating Applications?
The lower thermal conductivity of Corzan CPVC and other plastic piping materials compared to steel and copper often leads specifiers to wonder whether the material alone is sufficiently insulating for pipe in commercial plumbing and hydronic heating applications.
What is the size of a CPVC pipe?
CPVC is available in either nominal pipe sizes (NPS) from ¼” to 12″ or in copper tube sizes (CTS) from ¼” to 2″ . NPS sizes are available in either Schedule 40 or Schedule 80 wall thicknesses. CTS sizes for wall thickness have a standard dimension ratio (SDR) of 11 (i.e., the outside diameter is 11 times the wall thickness).3
What is the best material for hot water piping?
Since all plastics lose strength as temperature increases, the use of plastic piping is limited to operating temperatures less than 220°F. For domestic hot and cold water piping systems, CPVC and PEX are the most common materials. For chilled water distribution piping, many different materials may be used.
How much insulation is needed for a C404.5?

What is plastic piping used for?
Plastic piping for domestic hot and cold service water systems, and for HVAC systems in buildings , has been in use for many years and has become the dominant piping material for residential construction. One source1 estimates that plastic pipe systems are currently used in 75% of the potable piping systems in new residential construction, and this number is predicted to rise to 80% by 2015. Plastic piping is also used routinely in commercial and industrial applications.
Why do water lines sweat?
For example, city water lines entering a building will often sweat due to the relatively cold temperature of the water entering the building. Depending on the ambient conditions, plastic piping may minimize or eliminate the surface condensation and associated dripping from cold water pipes. However, when insulation is required by energy codes, ...
What is the difference between plastic and metallic piping?
Compared to metallic piping systems, plastic piping materials have a significantly lower thermal conductivity, which translates to lower heat transfer between the fluid and the ambient air. For some piping applications, this can be advantageous.

Heat Transfer Calculations
- The data from Table 1 demonstrates that the thermal conductivity of metallic piping is 30 to 3,000 times higher than typical plastic piping materials. However, the impact on heat transfer to or from the fluid will depend not only on the relative thermal resistances of the pipe wall, but also on the other thermal resistances in the system. For bare piping, the air surface coefficient normally repr…
Energy Code Requirements For Piping
- All of the current model energy codes contain insulation requirements for domestic hot water and HVAC piping. Although the details vary somewhat, the requirements are generally given as a minimum insulation thickness without regard to pipe material. As an example, requirements for service water heating from the 2012 IECC are given in Section C 404.5 and read as follows: C40…
Conclusion
- All current building energy codes and standards require pipe insulation on service hot water and HVAC piping. Requirements vary, but none of the model codes differentiate pipe insulation requirements based on pipe material.
