Description
INSUL-LOCK® II Self-Seal pipe insulation is an environmentally friendly, CFC-free, flexible elastomeric insulation, pre-slit with a factory applied pressure sensitive adhesive. It is black in color and identified as INSUL-LOCK® II. This superior closed cell insulation is designed to retard heat flow and prevent condensation when properly installed. INSUL-LOCK® II Self-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. INSUL-LOCK® II key physical properties are approved through supervision by Factory Mutual Research Corporation. INSUL-LOCK® II 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-LOCK® II has the same excellent insulation properties as standard INSUL-TUBE® and is used on similar applications such as refrigerant lines, cold water plumbing, roof drains, and chilled water systems. INSUL-LOCK® II is recommended for applications ranging from -70°F to 200°F (-57°C to 93°C) for both new and existing applications. INSUL-LOCK® II can be used with heat tracing/heat tapes. For best results, store and install INSUL-LOCK® II at temperatures above 40°F (4°C).
INSUL-LOCK® II’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. INSUL-LOCK® II has superior cold weather flexibility.
Installation
INSUL-LOCK® II 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 on the bottom of the pipe.
All butt joints must be sealed with an approved contact adhesive. Fittings are fabricated from miter-cut tubular sections or from INSUL-SHEET®.
Outdoor Applications
INSUL-LOCK® II 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, R-374 Protective Coating or approved jacketing or cladding should be used. For more detailed information refer to the Installation Guidelines.
Features & Benefits
INSUL-LOCK® II offers the advantage of easier handling & installation.
- Faster install
- Ideal for straight runs
- Less use of contact adhesives
Resistance to Moisture Vapor Flow
The closed-cell structure and unique formulation of INSUL-LOCK® II effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, INSUL-LOCK® II needs no additional protection.
Additional vapor barrier protection may be necessary for INSUL-LOCK® II when installed on low temperature surfaces that are exposed to continuous high humidity.
Flame and Smoke Rating
INSUL-LOCK® II Self-Seal pipe insulation in wall thicknesses of 3/8" (10 mm) through 1" (25 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.” INSUL-LOCK® II elf-Seal pipe insulation is acceptable for 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.
