Insul-Lock® White

Made in America

Designed for the HVAC/R Industry

White Elastomeric Insulation

INSUL-TUBE® WHITE is designed for exposed piping areas. INSUL-TUBE® WHITE is suitable for supermarket, hospital and school applications where a more hygienic appearance is preferred. INSUL-TUBE® WHITE meets all INSUL-TUBE® specifications and thermal properties.

Description

INSUL-TUBE® WHITE pipe insulation is an environmentally friendly, CFC-free, flexible elastomeric thermal insulation. It is white in color, and is available in unslit tubular form in wall thicknesses of 1/2", 3/4" and 1" in sizes ranging from 3/8" I.D. to 4 1/8" I.D. INSUL-TUBE® WHITE key physical properties are approved through supervision by Factory Mutual Research Corporation. INSUL-TUBE® WHITE is non-porous, non-fibrous and resists mold growth. The Bio-Guard™ antimicrobial system provides added protection against mold, fungal and bacterial growth.  The active ingredient in Bio-Guard™ is registered with the EPA.

Applications

INSUL-TUBE® WHITE is used to retard heat gain and prevent condensation or frost formation on refrigerant lines, cold water plumbing and chilled water systems. It also retards heat flow for hot water plumbing, liquid heating, dual temperature piping and many solar systems. INSUL-TUBE® WHITE is designed for the HVAC and Refrigeration industries.

INSUL-TUBE® WHITE is recommended for applications ranging from -70°F to 220°F (-57°C to 104°C). The expanded closed cell structure makes INSUL-TUBE® WHITE an efficient insulator and provides effective moisture vapor resistance.

INSUL-TUBE® WHITE has a very tough skin which withstands tearing, rough handling, and severe environmental conditions, and yet is quite flexible for easy installation. INSUL-TUBE® WHITE has superior cold weather flexibility.

Installation

With a factory-applied coating of talc on the smooth inner surface, INSUL-TUBE® WHITE slides easily over pipe or tubing for quick installation. When applied to existing lines, tubing is slit lengthwise and fitted into place. All seams and butt joints should be sealed with an approved contact adhesive, making sure both surfaces to be joined are coated with adhesive.

Resistance to Moisture Vapor Flow

The closed-cell structure and unique formulation of INSUL-TUBE® WHITE effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, INSUL-TUBE® WHITE needs no additional protection.

Additional vapor barrier protection may be necessary for INSUL-TUBE® WHITE when installed on low temperature surfaces that are exposed to continuous high humidity.

Flame and Smoke Rating

INSUL-TUBE® WHITE pipe insulation in wall thicknesses of 1" (25 mm) and below 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.” INSUL-TUBE® WHITE 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.
