Home/ Energy-saving products

Insulation products for commercial and industrial applications fall into three categories:

• Pipe, board and blanket insulation
• Insulated air duct products
• Insulation for metal buildings

Pipe, board and blanket insulation

Pipe insulation is a molded, heavy density, one-piece insulation made from inorganic glass fibers bonded with a thermosetting resin. It is produced in 3' lengths with or without a jacket and can be used on systems operating from 0º to 1000ºF (-18º to 538ºC).

Similar in composition to pipe insulation, boards and blankets are available plain, or with an FSK (Foil-Scrim-Kraft) facing, PSK (Polypropylene-Scrim-Kraft) facing or ASJ (All Service Jacketing). They come in a number of densities, thicknesses, widths and lengths and are used for heating and air-conditioning ducts, power and process equipment, boiler and stack installations, wall and roof panel systems, tanks, piping, valves, etc.

Insulation and air duct systems

A critical system in any building is its HVAC system. Fiber glass insulation is used in air handling systems for acoustical control, temperature control, condensation control and energy conservation. The primary types of fiber glass insulated air duct products are:

Fiber glass duct board

Duct board is made from resin bonded inorganic glass fibers. It's widely used in residential and light commercial HVAC systems. Duct board provides duct construction and insulation in a single step. It controls condensation, prevents air leakage, reduces air turbulence and noise or cross-talk through ducts, and delivers significant energy savings.

Fiber glass duct liner

Duct liner is adhered to the inside of a sheet metal duct or plenum, and combines superior sound absorption and excellent thermal conductivity. For more information about the sound absorption capabilities of fiber glass, click here.

Fiber glass duct wrap

Fiber glass duct wrap is a flexible and resilient blanket available in various thicknesses and densities used to insulate the exterior of sheet metal duct work. Duct wrap reduces heat loss or gain, conserves energy and controls moisture condensation.

Black Acoustical Ceiling Liner

Fiber glass wall and ceiling liner M is a flexible fiber glass blanket with a black mat facing adhered to one surface. It provides thermal and acoustical insulation and a visual barrier. Its smooth, tough surface resists damage during installation. It's primarily used in theaters, sound studios, public concourses and other areas where acoustical treatment is needed.

Metal building insulation

Metal building insulation is engineered specifically for metal building construction. It is a fiber glass blanket insulation that can be faced, or unfaced, depending on where it is used in the building. It is manufactured in lengths and widths to specifically fit between the steel girt and purlins found in metal construction.

• Controls Heat Flow. It acts as a barrier to slow down the movement of heat either from the outside coming in, or from the inside going out--reducing energy consumption, and resulting in lower fuel bills and a cleaner environment.
• Controls Noise. Metal walls and roofs are not good sound barriers. Metal building insulation greatly reduces the transmission of exterior sound to the interior of the building and absorbs noise within the building.
• Prevents Condensation. In most cases, metal building insulation has a vapor retarder facing which helps to prevent moisture from condensing in the building structural components.
• Increases Lighting Efficiency. Laminated facings on metal building insulation provide a bright, attractive wall and ceiling treatment that acts as a reflector to increase lighting efficiency.
