I need some technical information for a project I’m quoting. Where do I get it or is there someone I can call to help me with this?

Follow the product link on our website for specific product information or contact your local branch for specific technical information.

My building inspector has informed me that my flue pipe does not meet the minimum clearance requirement to combustibles. What is available to solve my problem?

Several options are available to solve this problem. Different states and jurisdictions vary on the acceptable way to remedy this situation. The local fire inspector should be consulted to determine the proper application.

What does “R-Value” mean?

The R-value is the measure of heat flow through a substance, i.e. insulation.

What’s the “R-Value” for fiberglass pipe insulation?

This is not an easy question because of the cylindrical configuration and because inner diameters and outer diameters do not vary uniformly with pipe size and nominal thickness. Also, pipe usually operates at mean temperatures vastly different than 75F. The actual worth of the calculation should be questioned. In saying all of this, some specs have been written which require certification of pipe insulation to some minimum R-Value. Each branch has received a chart for most pipe sizes and insulation thicknesses from Knauf Insulation and can provide it to so if you would like. R-values are based on flat surfaces, and tested as such. Being that the fiberglass pipe insulation is rounded, to fit pipe, there really isn’t any real R-value calculations, however if needed, the manufacturer can provide in writing, an explanation of the value.

Do you have material safety data sheets, MSDS sheets, or submittal sheets available?

Yes, all of these sheets are available on our Product pages or by clicking here [link].

I have a 3” pipe with an operating temperature of “Y” degrees Fahrenheit, what thickness of insulation do I need to reach a safe surface temperature for personnel protection for OSHA?

We can provide an accurate required thickness compensating for different insulation jacket finishes with a quick call to your local branch.

How much insulation should I put on to have a return on investment (ROI) of one year?

We can provide a mini energy audit to provide the answer using the “3E” computer program and your energy bill. A site visit may be required. Contact your local branch office.

I am Building a home theater in my basement, how do I keep the sound contained in the basement?

To stop sound transmission we recommend a composite of low density (sound absorbers) and high density (sound barriers) to create a barrier to different frequencies of sound using mass loaded vinyl and fiberglass batts. Call your local branch for more information.

In the home theater I am building, how do I absorb the sound in the walls to improve the acoustics?

The best solution is to attach duct liner over the walls and ceiling utilizing pins and domed washers. A covering of cloth for an aesthetic finish completes the installation. Call your local branch for more information.
