Also, open cabinet and closet doors where pipes are visible to allow warmer air to flow through. Exposed plastic or copper pipes accessible in attics and basements should be inspected and layered or blown insulation applied, Watson says. Also, short runs of pipe exposed under peer and beam foundations should be insulated.
To increase their insulating capabilities, make sure that you seal the slits shut after putting them on. While PVC pipe is durable and resists UV rays and damage from water and chemicals, you likely still need PVC insulation. PVC is made from plastic and can freeze and crack in cold weather. The experts at Armacell write that PVC insulation is a must for these pipes, recommending it for other plastic pipes as well. Insulation can reduce heat gain/loss up to 75 percent and can save energy costs.

This option is good if there is not much space between your water pipes and the exterior walls. Insulation is typically seen as a means to prevent heat gain or loss. Energy-efficient building design must address interior piping systems and specify the right insulation materials in the right thicknesses. These mechanical systems particularly benefit from insulations ability to prevent condensation, moisture intrusion and system failures. Too frequently, it is assumed that all insulation is equally suitable for any application. However, cold and hot pipe systems need different attention and improper specifying can lead to system failures, energy waste and even building closures.
Pipe insulation is available in various diameters for pipe sizes, so measure your pipes before shopping. Remember that you may have to cut out holes in the PVC insulation for pipe valves. The company was founded as a trading company for armature winding products for the repair of electric motors in today's head office in 1945. Production of motor terminal boards, cell connectors, clamps, cable lugs, slip ring elements, carbon brushes, brush studs, terminal insulators, retainer insulators, stud terminals.

This moisture prevention also helps prevent mold and mildew from forming in your pipes and house. You can use any of the four choices described on indoor and outdoor pipes. To install conventional foam and self-sealing PVC insulation, measure the pipe that needs to be protected and transfer that measurement to a tube of foam pipe insulation.
Being proactive to ensure that pipes dont burst and cause thousands of dollars in water damage is a good rule of thumb during the winter. Production and sale of electrical engineering special items, including electrical terminals. The experts at Bob Vila encourage the use of PVC insulation, detailing the available types. Fiberglass pipe covers, which are made of hinged, paper-coated, rigid fiberglass, are the best option when a pipe’s temperature may become exceptionally high. Conventional foam insulation is more common, and these pieces have slits on their slides to help fit them over your pipes.

In some cases, heat tracing is necessary for additional freeze protection in addition to insulation. If the goal is to lower water-heating costs, then it is critical to insulate hot water pipes wherever there is access to them in a building. If the goal of pipe insulation is to eliminate pipe sweating and mold issues, then cold water pipes are in the most need of insulation. Water supply pipes exposed to unheated spaces and exterior walls can freeze, burst and flood buildings. Insulating your cold water pipes can prevent these damages while also avoiding the problem of pipe “sweating” caused by moisture condensation. Controlling moisture is vital for chilled-water systems and thermal efficiency.
Instead of installing pipes in the concrete slab, some builders run them in attics. While their flexibility provides some freeze resistance over PVC piping, the lines should still be properly insulated, says Jeff Watson, Regional Pro Sales Manager at Home Depot. Older water heaters may require an insulated wrap or blanket when temperatures dip below freezing.

The experts at PVC Pipe Supplies add that PVC pipes can also handle exhaust and air ventilation. CPVC pipe is similar to PVC, but it can withstand a wider range of temperatures, between -15 and 200 degrees Fahrenheit. It’s lightweight, easy to install and transport, and resistant to blockages and high water pressure because it’s somewhat flexible. Aidan and I recently built a marble run out of foam pipe insulation, cable ties, duct tape, and a framework of PVC pipe. In recent years, home builders in the south have used flexible poly pipe water lines instead of copper, which has escalated in price.
Watson recommends using hard faucet covers for all outdoor faucets or hose bibs around the home. A popular and inexpensive way to keep cold air out, the covers usually hook on the spigot and are tightened snug to the side of the house with a cord. Blankets typically cost $20-$25 and fit around the water heater.
To prevent risk of fire, do not insulate pipes within six inches of the gas water heater flue. If you must insulate this area, use unfaced fiberglass pipe-wrap insulation for this area. According to the writers at This Old House, PVC pipes often are used for venting, draining, and waste removal in shower drain lines, toilets, sinks and main water supply pipes.
He said its important to protect all faucets that have been capped. For vacant homes awaiting rental, Watson says its a good idea to keep the heat on during the winter. The thermostat needs only to be set above freezing to prevent damage in most cases.
Next, slip the foam insulation over the pipe with the split edge on the top. If it’s self-sealing, pull off the coverings and attach the edges otherwise, seal them with some good old duct tape. Self-sealing foam insulation is similar to conventional foam insulation, but it has an adhesive along the slits. You remove the tape and press the adhesive strips together without any additional tape. Spray foam insulation is another kind of PVC insulation, but this process usually requires a professional.
One of the most common ways to protect exposed indoor pipes is to wrap them in flexible tubular pipe insulation or with heat cables. You can hire professionals to complete a spray foam insulation, and products like pipe wrap are sold in aerosol spray cans. Pipe wrap, both non-flammable and water-resistant, is designed to prevent pipes from sweating. Another option is to wrap pipes with a heat cable, which uses a low electrical current to warm the lines. Other pipes can be wrapped with inexpensive tubular pipe insulation. Typically, you can buy tubular foam pipe insulation in 6-foot lengths of rubber or PE foam.
When it gets cold out and the faucet isnt protected, it can cause quite a bit of damage, he said.
