2. Fiberglass Insulation is Naima 202-96 compliance

This is an independent test performed by Home Innovations.  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 hits the field from these manufacturers which is less than performance.  With NAIMA 202-96 fiberglass guarantee you get the R-value you ask for.

An additional standards met or exceeded:

  • ASTM C991-08, Standard Specification for Flexible
    Fibrous Glass Insulation for Metal Buildings; Type II.

NAIMA 202-96® (Rev. 2000) Certified Fiber Glass Metal Building Insulations are designed to be laminated and are intended for use in the walls and roofs of manufactured buildings.

3. Comcheck- Energy Compliance Certificate

Is a program put out by the department of energy.  This program models buildings in compliance software to verify government energy code performance.  The certificate will specify a percentage equal to or better than code requirements.  Our company will provide this certificate for a building with any order. COMCheck certificates are available on request for full building orders to guarantee energy code compliance

4. Fabric and Banding

Be aware 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.  Most erectors will complain about this kind of banding twisting up on the screw as they try to attach the strapping.  Factory Steel Overstock is committed to offering the correct amount of banding and screws per order request.

5. VRR+ instead of VRR

As a standard practice, Factory Steel Overstock prices fiberglass insulation with a stronger VR-R “PLUS” facing instead of the industry-standard VR-R for no additional charge.

6. Secure Price and Quick Delivery

Some firms will indicate that they have the option to increase the price based on insulation availability. This means these firms can process the order and then hit the customer with an increase at the last minute before shipping. At that point, the customer is stuck and may have to wait several weeks to get their insulation delivered if they don’t accept the price increase.  With Factory Steel Overstock, there are no surprises. There is never a possibility of a price increase after the initial order! The price and savings are guaranteed!

Fiberglass insulation is delivered within a quick 2-3 weeks and the customer is called within 48 hours of delivery.

Standard Specifications and Features

Steel building insulation is basically blankets of woven long-strand fiberglass that are laminated on one side to a vapor-barrier facing.  Facing materials are applied to fiberglass insulation blankets to serve as a vapor retarder as well as a protected cover over the fiberglass. This vinyl-reinforced backing is far more durable than vinyl alone.   

  • A 3″ tab runs along the length of both sides of rolled-out insulation for easier handling during installation.
  • Double face tape and patch is a standard inclusion on insulation quoted by 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.

Understanding R – Value

R-Value is based on measuring the amount of heat loss, or ability to retard the loss of heat flow. Understanding R-value with fiberglass insulation is easy: The R-value is directly related to the fiberglass thickness. The thicker the fiberglass blanket you have, the higher the R-value. Factory Steel Overstock quotes R-Value 8 to 30.

Simple Installation Procedure for Single Layer Blanket

Pdf of More Detailed Recommendations for installing Fiberglass Insulation

Locate by Single layer information
  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

Simple Installation Procedure for Double Layer Insulation System: 

double layer picture

The great thing about fiberglass insulation is you can just add an additional layer and increase your R-value. The highest R-value you can have with a single layer of insulation is R-19 which is 6”.  Your purlin depth determines the thickness of your bottom layer.

  1. Faced fiberglass (we always include a reinforced faced backing) rolls are installed between the purlins and/or girts, filling the cavity. This cavity is important, for it allows the insulation to maximize its efficiency.
  2. This insulation is secured by banding that is screwed to the underside of the purlins. An additional layer of unfaced insulation is then placed over the top of purlins or girts, creating a double-layer high R-Value system.

Insulation 101

Most people are familiar with fiberglass insulation.  It is what was in their attic when growing up–though there have been improvements on its facings.

Steel building insulation is blankets of woven long-strand fiberglass that are laminated on one side to a vapor-barrier facing.  Facing materials are applied to fiberglass insulation blankets to serve as a vapor retarder as well as a protected cover over the fiberglass. This vinyl-reinforced backing is far more durable than vinyl alone.  

Not all Fiberglass Insulations are the same

  • Fabric and Banding: Be aware 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.  Most erectors will complain about 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 insulation availability. This means these firms can process the order and then hit the customer with an increase at the last minute before shipping. At that point, the customer is stuck and may have to wait several weeks to get their insulation delivered if they don’t accept the price increase. A few steel building outlets are doing this same tactic.

With Factory Steel Overstock, there are no surprises. There is never a possibility of a price increase after the initial order! Insulation is normally delivered within 3 weeks and the customer is called within 48 hours of delivery. If an apple-to-apple price and feature comparison is made, it will be self-evident the better choice!

Why do I need insulation?

Locate by Why I need insulatioin

An insulation R-value is the measurement of a material’s ability to stop heat and cold transfer.  No matter what a metal building’s usage, insulating it will be of value.  Because of the unique nature of a steel building, it requires a vapor barrier and radiant barrier. 

  • The summer heat (sun’s rays) on a steel surface will create extreme heat temperatures inside the building.
  • In addition, the cold winter temperatures are exaggerated by the metal roof and wall sheeting making it frigid inside.  Warm temperatures coming in contact with cool metal roofs or walls create sweating (condensation).
