High performance insulation for industrial applications Stone wool, when used to insulate against loss of heat in the process industry, can result in huge energy savings. Wired mats, which are lightly bonded stone wool mats, are usually stitched with galvanised wire or stainless steel wire onto a galvanised wire mesh or stainless steel wire mesh. It is a time-tested universal solution able to resist high temperatures when used for applications on pipeworks, boiler walls or furnaces. ROCKWOOL ProRox Wired Mat series with its high quality stone wool insulation provides energy efficient and cost effective solutions to protect both the environment and your investment. Made of stone, it is naturally fire-resistant to temperatures above 1000 C and does not contribute to emission of significant quantities of toxic smoke in the event of a fire. 3

Why choose ROCKWOOL ProRox Wired Mats? LOWEST THERMAL CONDUCTIVITY Highest Energy Savings Features exceptionally low thermal conductivity, and is by far the best performing high thermal insulation mattress available in the Indian market today for this category. Thermal Conductivity Advantage of ProRox WM 960 (100kg/m 3 ) Lamda (mw/mk) 110 100 90 80 70 60 50 40 What does NACE say? COMBATING RISK OF CORROSION * National Association of Corrosion Engineers - NACE SP0198-2010 (2.1.2) Keeps Your Maintenance Costs Under Control With its lowest water absorption and chloride content, ProRox Wired Mats minimise the risk of corrosion under insulation (CUI). CUI of carbon steel is possible under all types of insulation. The insulation type may only be a contributing factor. The insulation characteristics with the most influence on CUI are: Water retention, permeability and wettability of the insulation Water-leachable salt content in insulation, such as chloride, sulphate and acidic materials that may contribute to corrosion 30 0 50 100 150 200 250 300 Mean Temp ( C) ASTM C592 requirement ( I,II, III ) IS 8183 slag wool-1 Because CUI is a product of wet metal exposure duration, the insulation system that holds the least amount of water and dries most quickly should result in the least amount of corrosion damage to equipment.* ROCKWOOL ( ProRox WM 960 ) 4

Lowest water absorption What does the EN1609 Test Results say? Water absorption (kg/m²) 6 4 2 0 0.3 ROCKWOOL ProRox 1.269 slag wool-1 6.425 slag wool-2 Test results of ROCKWOOL ProRox Wired Mat shows its water absorption at 0.3kg/m 2, making it the lowest in water absorption as compared to other stone/slag wool materials. ROCKWOOL stone wool has been hydrophobically treated and therefore provides effective protection against water absorption across the entire insulation thickness and gives the lowest in class water absorption than best available in market when tested according to EN1609. LOWEST SHOT CONTENT Highest Thermal Performance Due to the manufacturing technology, ProRox Wired Mats have the lowest in class shot content. Shots in products lower the insulation's thermal performance and add to the weight of insulation. What does the ASTM C1335 Test Results say? 150 micron sieve - shot content % 20 15 10 5 0 8.09 ROCKWOOL ProRox 12.73 slag wool-1 15.92 slag wool-2 Lowest chloride content What does the ASTM C795 Test Results say? Chloride content (ppm) 10 5 0 4.97 5.01 8.33 ROCKWOOL ProRox slag wool-1 slag wool-2 Test results of the chloride content in ROCKWOOL stone wool showed low leachebale substances of < 10 ppm chloride. This enables ROCKWOOL ProRox Wired Mats to give the highest protection against corrosion under insulation. 5

Benefits of ROCKWOOL ProRox Wired Mats ProRox Wired Mats with best in class lowest thermal conductivity, utilising state-of-the-art and sustainable manufacturing technology by ROCKWOOL, is one of the best performing insulation materials available. With a strong focus on developing high-performing solutions for the technical installations, we set the standards in innovative products with high quality service in key applications of insulation for pipeworks, vessels, boilers, storage tanks and columns among others. How does our ProRox Wired Mats provide better heat loss protection than others in the market? Assuming same pipe diameter (900mm), ambient temperature, wind speed, emissivity, operating temperature (300 C), as well as similar product density and thickness, the results below calculated as per ASTM C680 (Using Steady State Formula), depicts the superiority of ProRox Wired Mat.
