Products > FlexTherm Seam-Seal DescriptionFlexTherm® Seam-Seal pipe insulation is an environmentally friendly, CFC-free, flexible elastomeric insulation, that is pre-slit with a factory-applied pressure sensitive adhesive. It is black in color and marked in gold ink. This superior closed cell insulation is designed to retard heat flow and prevent condensation when properly installed. FlexTherm® Seam-Seal pipe insulation is pre-slit with a factory applied specially formulated bonding adhesive applied to both seam surfaces and comes with convenient built-in release liners which allow for easy installation. It is available in wall thicknesses of 3/8" through 1" and in sizes ranging from 3/8" to 4" IPS. It is non-porous, non-fibrous and resists mold growth. Applications
FlexTherm® Seam-Seal’s self-seal closure system is designed to save labor costs, particularly on straight runs. It greatly reduces the use of contact adhesives, thus allowing for improved working conditions and compliance with OSHA requirements. FlexTherm® Seam-Seal can be used with heat tracing/heat tapes. InstallationFlexTherm® Seam-Seal is pre-slit with convenient built-in tabs for easy installation: slip on the tube, pull the tab, pinch it shut and, apply pressure to the seams. The seam should be positioned to be on the bottom of the pipe. See technical bulletin for installation instructions in cold temperatures. All butt joints must be sealed with an approved contact adhesive. Fittings are fabricated from miter-cut tubular sections or from FlexTherm® Sheet Insulation. Outdoor ApplicationsFlexTherm® Seam-Seal pipe insulation is made from a UV resistant elastomeric blend. For moderate UV exposure, no additional protective coating needed. However, for severe UV exposure (rooftop applications) or where optimum performance is required, 374 UV protective coating or approved jacketing or cladding should be used. For best appearance, two coats are recommended. For more detailed information refer to the Application Guide. Features and BenefitsFlexTherm® Seam-Seal offers the advantage of easier handling & installation Resistance to Moisture Vapor FlowThe closed-cell structure and unique formulation of FlexTherm® Seam-Seal effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, FlexTherm® Seam-Seal needs no additional protection. Additional vapor barrier protection may be necessary for FlexTherm® Seam-Seal when installed on low temperature surfaces that are exposed to continuous high humidity. Flame and Smoke RatingFlexTherm® Seam-Seal pipe insulation in wall thicknesses of 3/8" (10 mm) through 1-1/2" (38 mm) has a flame spread rating of 25 or less and a smoke development rating of 50 or less as tested by ASTM E 84 Method of Testing entitled: “Surface Burning Characteristics of Building Materials.” FlexTherm® Seam-Seal pipe insulation is acceptable for use in duct/plenum applications meeting the requirements of NFPA 90A/B. Numerical flammability ratings alone may not define the performance of products under actual fire conditions. They are provided only for use in the selection of products to meet limits specified, when compared to a known standard.

FlexTherm® Seam-Seal has the same excellent insulation properties as standard FlexTherm® pipe insulation and is used on similar applications such as hot and cold water plumbing. FlexTherm® Seam-Seal is recommended for applications ranging from -70°F to 200°F (-57°C to 93°C) for both new and existing applications. For best results, store and install FlexTherm® Seam-Seal at temperatures above 40°F (4°C).
