Insulation for steel buildings are blankets of woven log-strand fiberglass that is laminated on one side and has a vapor-barrier facing on the other. These materials are added to fiberglass insulation to work as a vapor retarder and protect the fiberglass. The vinyl-reinforced backing is much more strong/durable than just vinyl by itself.

  • On both sides there will be a 3′ tab that goes the length of the insulation when rolled out for an easy installation process.
  • We include double faced tape and patch based on building measurements. Quotes of a specific square ft or number of rolls, patch, and double-face tapes are added upon request. 
  • Customers can indicate the cut length of their rolls. 
  • Standard insulation width: 3′, 4′, 5′, and 6′. 
  • Factory Steel Overstock standard quotes include a stronger VR-R “PLUS” facing instead of the industry-standard VR-R. 

Not all Fiberglass Insulations are the same

  • Fabric and Banding: Be cautious when purchasing that there are insulation systems that are of low quality. Some sellers utilize fabric that is thin and cheap, as well as use plastic nylon strapping in place of traditional metal banding compared to vinyl.  When installing erectors will be frustrated with this kind of banding twisting up on the screw as they try to attach the strapping. 
  • Naima 202-96 compliance. This is an independent test performed by Home Innovations.  This test is the gold Standard for Flexible Fiberglass Insulation to be Laminated for Use in Metal Buildings. When the facing is laminated to the fiberglass it crushes the fiberglass.  The test ensures that after manufacturing the product unrolls to the specified R-value.   Some manufacturers do not want to pay for this test and say they do in-house testing.  In these cases, the product often arrives from these manufacturers with less than claimed performance.  Simply put, it means other insulation outlets, R-19 (6″) insulation may show up at the job site as 4″ or 5″ with a lower R-Value!  Our NAIMA 202-96 compliance guarantees you get the R-value you ask for.
  • Comcheck- Energy Compliance Certificate  COMcheck is a program put out by the department of energy.  This program models buildings in a compliance software to verify government energy code performance as it relates to insulation.  The certificate will specify a percentage equal to or better than code requirements.   COMCheck certificates available on request
  • Secure Price: Some firms will indicate that they have the option to increase the price based on how available this insulation can be. This means these firms can process the order and then hit the customer with an increase at the last minute before shipping based on availability. At that point, the customer is stuck and may have to wait many weeks to get their insulation delivered if they don’t accept the price increase from the original quote.

The amount of heat loss is measured in R-Value for fiberglass insulation. It is very simple to understand R-Value: The ticker the fiberglass is the higher the R-Value will be in return. We provide customers with R-Value 8-30.

  1. You simply place the insulation roll over the top of the roof purlins and / or wall girts. This is done prior to the exterior metal panels being installed.
  2. The fiberglass rolls are essentially sandwiched between the interior metal and the exterior sheeting.
  3. The vapor barrier (usually white finish) is faced towards the inside of the building, giving the building a clean finished look. We always Re-enforce this facing so that our customers have the sturdiest backing. With a single layer application, you can achieve R-Values up to R-19, but not higher.
  4. The 3” tabs are to be rolled over and stapled. Orders come with double-sided tape for easy adherence to building, and a small supply of patch tape to assist with minor tears if needed

Should I insulate my steel building with Fiberglass Insulation?

Should I insulate my steel building

Numerous options are available to insulate your steel building; however, fiberglass is the tried and proven insulation. Your steel building should have a fiberglass blanket made of woven fiberglass fibers. Ideally, your insulation should have a vapor barrier. Our standard type is VRR+ facing (Vapor Retard). This type of insulation is designed explicitly for steel buildings. 

What R-value of Fiberglass Insulation Should I Choose for my Steel Building?

What R Value

There are numerous R-value options available. The appropriate R-value for fiberglass insulation depends on your climate, codes, building type, and desired purpose intended for the insulation. 

For instance, if you are insulating a new home, attics typically require R-30 to R-60, walls R-13 to R-21, and floors R-25 to R-30. However, most will use considerably fewer R-values when insulating a steel building because they do not live in the structure.  For instance,  most of our customers order R-10 to R-19 for their steel building. Again, this is also influenced by the climate conditions. We recommend you consult one of our experts for guidance with this.
