Nature's way to keep water away

Just like a bird's feathers, stone wool is nature’s own invention. It absorbs less water, dries out faster and has technically superior insulation performance.

Properly planned and installed insulation solutions provide many advantages such as cost and energy savings, decrease of heat losses, improvement of process control, reduction of emissions and maintenance, as well as prevention of corrosion under insulation (CUI). 

CUI is one of the biggest challenges when it comes to insulation solutions for industrial applications. Paroc has been selling water repellent (WR) products for more than 20 years and has been continuously investing in research and development to improve its product properties. Latest tests from independent test laboratories prove that Paroc’s WR product range for industrial applications has market-leading properties for stonewool insulation material – including lowest water absorption and highest temperature range.

Stone Beats Water

Low water absorption is a very important property, since most industrial insulation solutions are at risk of being exposed to water, high humidity or other liquids. Dry insulation always performs better than wet insulation. Water in the insulation material will dramatically decrease performance and add weight to the insulation, in addition to increasing the risk of generating a corrosive environment at the surface of the insulated equipment.

Corrosion is accelerated by the duration of any wetness, therefore protection against water trapped under or in the insulation material itself becomes a function of time. In other words:

Less water and faster dry-out = less corrosion

PAROC WR Pipe Sections are tested at independent laboratiories according to European (EN), British (BS) and American (ASTM) standards.
