Black Pipe Insulation Foam Tube

What it does: Thermal insulation — keeps pipes from freezing in the cold or sweating in the heat. Energy saving — by reducing heat loss, it saves that precious electric bill from sky-rocketing. Protective armor — stops pipes from rattling, getting dinged, or corroding prematurely. Noise reducer — no more clanging in the walls when water’s running. Where you see it: Home plumbing. HVAC systems (heating, ventilation, air conditioning).
