Product Data Sheet VaporWick Pipe Insulation those listed in ASTM C585. This may cause an improper pipe fit and result in overloading of the system and/or failure of the closure tape resulting in system failure. For severely corroded pipes, rust and scale should be removed before installation. Ensure that the recommended thickness has been specified to prevent surface condensation. The VaporWick System is not recommended for outdoors or exposed piping where additional jacket finish is required. Application should be at temperatures between 25F (-4C) and 110F (44C). The evaporation holes must remain uncovered and unpainted at all times after installation. Painting or covering over the evaporation holes will defeat the function of the system. Use of stickers, labels, or colored tape is recommended for pipe service identification. Technical Information The VaporWick System was developed for piping systems that operate at below ambient temperatures, which present special considerations due to the possibility of water vapor migration to the cold pipe surface. If the operating temperature of the piping system is below the dew point of the ambient air, moisture will condense on the cold pipe surface. With time, the condensed water will accumulate, reducing the R-value of the insulation, and possibly resulting in dripping, which can stain ceiling tiles and damage building contents below. The problem is not limited to open cell insulation materials. Many closed cell insulations have low water vapor permeability, yet water buildup is a serious problem due to incomplete sealing at longitudinal seams and butt joints. Traditionally, designers have relied on vapor retarders and mastics or other sealants to slow the ingress of moisture. This approach is highly dependent on the skill and experience of the installers. In contrast, VaporWick Pipe Insulation incorporates a patented Physical Property Data Property Test Method Value Operating Temperature Range 32F to 220F (0C to 104C) Jacket Permeance ASTM E96, Desicant method < 0.15 perm Jacket Temperature Limitation ASTM C1136 225F (107C) Burst Strength, min ASTM D774/D774M 55 psi Corrosion Resistance ASTM C665 Meets requirements Fungi Resistance ASTM C1338 Meets requirements Composite Surface Burning Characteristics 1 Flame Spread Smoke Development ASTM E84, UL 723, and CAN/ULC-S102 < 25 < 50 1. The surface burning characteristics of these products have been determined in accordance with ASTM E84, UL 723, and CAN/ULC-S102. These standards should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment, which takes into account all of the factors, which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating. Product Availability VaporWick Pipe Insulations are available in thickness and for pipe sizes as follows. Insulation Thickness Nominal Pipe Sizes Inches (mm) NPS, inches (DN, mm) 1 (25) -24 (15-600) 1 (38) -24 (15-600) 2 (51) -30 (15-762) 2 (64) 2-30 (50-762) 3 (76) 3-30 (75-762) For additional sizes, check with your Owens Corning representative.
