哪种类型的热水管道保温效果最好?

I have read that heating a product will cause it to release any VOCs, do you have a preferred product for hot water pipe insulation that won’t off-gas into homes? I have strong sensitivities to chemicals and its been hard to keep the air quality of my new build, so I don’t want to mess up on something small like this. Thanks!
That’s a great question, and a great practice.Insulating hot water pipes can show a savings of up to 20% on your totalwater heating costs.
There are a few products used forinsulating water lines比如一个简单的泡沫护套，它的绝缘值约为R-2。这是住宅建筑中通常使用的，它们要么是膨胀合成橡胶，要么是膨胀聚乙烯。
还有一种是玻璃纤维护套，它更常见于商业和机构建筑，而不是住宅，尽管它提供了更好的隔热系数(接近R-4)。
If indoor air quality is a top priority for you, we would recommend you opt for the polyethylene foam insulation as it does not emit odors or VOCs. The synthetic rubber (or EPDM) sheaths can produce odors that adversely affect people who are extremely sensitive to chemicals. This information comes from Canada Mortgage and Housing Corporation (CMHC), despite the fact that this product is UV resistant and therefore acceptable for use outside, which is not the case of polyethylene.
最后，几乎所有品牌的玻璃纤维绝缘材料都含有一种甲醛基粘合剂，当产品暴露在高湿度和高温中时，这种粘合剂会逃逸到周围的空气中。玻璃纤维护套的特点是具有较高的绝缘系数，但可以通过在较小的护套上安装直径较大的聚乙烯泡沫护套来实现。你可以把还暴露在绝缘胶带上的部分包起来，完成工作。
Remember that cold water pipe insulation is also a good practice that prevents moisture condensation on the cold walls of the pipe, which protects nearby building materials from the risk of any water damage.
