Basics of Insulation - Commercial

Save more than energy.

Did you know that insulation saves commercial building owners more than $9.6 billion in energy costs annually?

Insulation also reduces annual energy use by 12 quadrillion BTUs, roughly 15 percent of total energy usage. It also diminishes power plant emissions, cutting carbon dioxide . (The figures include both commercial and residential buildings and are taken from the study “Green and Competitive: The Energy, Environmental and Economic Benefits of Fiber Glass and Mineral Wool Insulation Products.”)

One third of the energy used in commercial buildings is devoted to heating and cooling. That’s why it makes good business sense to maximize the fiber glass insulation in your building(s) to achieve greater energy savings and reduce heating and cooling loads.

Of course this is just the tip of the iceberg. There are layers of benefits to adding glass mineral wool insulation in commercial buildings - from increased energy savings, temperature and condensation control to noise reduction and environmental sustainability.

FACT: The Orlando Sentinel reported that Stetson University has saved more than $15,000 a month in energy bills by installing 30% more insulation than required by building codes. Visit for the complete article.

Improve comfort and control condensation.

A temperature controlled work environment is vital to employee health and productivity. Every office worker knows that a comfortable climate is a key factor in productivity; insulation in walls, ceilings and ducts makes it possible to maintain a comfortable environment for building occupants.

To maintain consistent temperature throughout the building, fiberglass duct insulation products help a building’s HVAC system deliver conditioned air at design temperatures without over-working the HVAC system. Besides potentially reducing the size of HVAC equipment, properly insulated ducts also contribute to reduced operating costs.

Preventing unwanted moisture, especially in the HVAC system, is another important function of insulation in commercial construction. Glass mineral wool HVAC insulations help prevent moisture from condensing on the inside or outside of ducts, and dripping onto ceiling tiles.

Improve productivity.

71% of office workers list noise as a key impediment to productivity. In fact, noise pollution is a major environmental problem; and exposure to excessive noise causes stress, poor concentration, productivity reduction, fatigue and loss of psychological well-being. Glass mineral wool insulation in walls, ceilings, floors and ducts significantly reduces the amount of noise inside buildings.

Glass mineral wool insulation products, specifically duct board and duct liner minimize the transmission of HVAC noise, such as expansion and contraction of steel ducts (popping and cracking), fan noise, etc. Fiberglass acoustical wall and ceiling insulations also reduce noise transfer from one room to another.

Commercial and Industrial Applications

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

  • Mechanical insulation
  • HVAC insulation
  • Insulation for metal buildings

Pipe, Board and Blanket Insulation

Pipe Insulation, Insulation Board and Elevated Temperature Board, Panels and Blankets 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. Glass mineral wool insulation is used in air handling systems for acoustical control, temperature control, condensation control and energy conservation. The primary types of glass mineral wool  insulated air duct products are:

Glass Mineral Wool Duct Board

Widely used in residential and light commercial HVAC systems, Air duct board provides duct construction and insulation in a single step.

Glass Mineral Wool 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.

Glass Mineral Wool Duct Wrap

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

Black Acoustical Wall and Ceiling Liner

A flexible glass mineral wool blanket with a black mat facing, Wall and Ceiling Liners provide thermal and acoustical insulation and a visual barrier 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 glass mineral wool 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. Metal Building Insulation controls heat flow, absorbs noise, prevents condensation and increases lighting efficiency.

A more sustainable environment.

The strongest trend driving today’s commercial construction is sustainable design to create efficient, affordable, comfortable buildings using products that reduce the negative impact on the environment. Glass mineral wool insulation is inherently a “green” product. While it has a long history of proven thermal and acoustical performance, it is one of the most technologically advanced sustainable building materials available today—particularly when assessing its impact over the product lifecycle.

Insulation currently in place in commercial buildings reduces the amount of carbon dioxide released into the atmosphere (through energy savings) by 780 million tons per year. (Source: U.S. Dept. of Energy). These gases are directly linked to global warming. So when you think about how to save energy and reduce your heating and cooling loads, you’re also making a positive impact on the environment.
