Lightweight blankets designed to provide superior dimensional stability, excellent thermal and acoustical performance, and easy handling and installation. Comes in 2” x 120’ rolls that can be separated into 1” so you actually have 240’ to a roll. Separates easily and seems to have a some kind of light sticky material that holds it together but once separated feels like nothing is there. OC’s EcoTouch RA Series Insulation comes in many different thicknesses, widths, layers, and densities depending upon the specification requirements you are attempting to meet Regarding standard 10’ spiral pipe, please note OC offers solutions such as: Specifically, OC’s 1” x 60” x 120’ bisected rolls are essentially 2” of insulation that is cut in half to make two separate 1” layers of insulation continuously rolled together within 1 roll Specifically, OC’s 1” x 60” x 120’ bisected rolls provide labor savings to the contractor as once you measure the insulation required to insulate the double-wall application and cut one time and get two 60” (5’) pieces of insulation since they are two layers of insulation in a continuous roll OC’s EcoTouch RA Series product is very soft and holds adhesive very well OC’s EcoTouch RA Series product is also very flexible, rather than stiff, which means it will form better around the circular inner-wall of the spiral duct pipe Design Flexibility: The RA product line offers a wide range of thermal, acoustical, and mechanical performance levels and densities to provide cost efficient performance in many varied applications. These products are available in both roll and batt form. Dimensional Stability: RA products have excellent resilience and compressive strengths. Non-corrosive: RA is non-corrosive, and will not accelerate corrosion on copper, aluminum, or steel. Excellent Acoustical Properties
