Why do we need insulation for pipes?
When the surfaces of plumbing pipes are cooler than the surrounding air, insulation helps control the condensation that, if left unchecked, would slowly corrode the pipes and their fittings, eventually leading to a massive failure. Though condensation may seem like a remote concern, it’s not at all uncommon, particularly when cold-water lines come into contact with warm, humid air. Special vapor barrier-wrapped pipe insulation prevents warm air from reaching the pipes.
Why is pipe insulation important?
Among the unsung benefits of pipe insulation, its ability to minimize heat gain and loss may be the most important. As water travels along the plumbing lines in a home without pipe insulation, hot water tends to lose heat and cold water tends to gain heat. Introduce pipe insulation, and you greatly diminish these otherwise inevitable inefficiencies. So in the case of a hot-water pipe, it may not sound like a big deal for the plumbing run not to lose heat, but the benefits are very real: You get lower monthly energy bills, and you don’t need to wait as long for the hot water to reach the fixtures in your kitchen or bathrooms.
Is asbestos pipe insulation safe?
Even today, some older homes still have pipe insulation that contains asbestos.
