Owens Corning® EcoTouch® Certified R Metal Building Insulation is a light density fibrous glass blanket.  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. 

Specifications:

 

  • ASTM C991-08, Standard Specification for Flexible
    Fibrous Glass Insulation for Metal Buildings; Type II.
  • NAIMA 202-96 (Rev. 2000) Standard for Flexible
    Fiber Glass Insulation to be Laminated for Use in
    Metal Buildings.

R-Values and Blanket Thickness

Depending on your local climate and comfort expectations, research the typical R-Values for your building interior.

Most popular choices which we have priced online and for add-ons in Option B – Build Your Own Package are:

  • 3″ R-10 roof and wall

  • 6″ R-19 roof & 4″ R-13 wall combination

Simple Installation Procedure for Single Layer Blanket:

  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.  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.
  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 most sturdy 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. 

Procedure for Double Layer Insulation:

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.

The Basics of Steel Building Codes

In summary, you should be familiar with the following codes prior to building purchase:

  • Snow Load/ Wind Speed
  • Wind Exposure, Example: Exposure B or C
  • Governing Code, Example: IBC 2009, 2014 or 2015
  • Current website prices reflect IBC 2015, Wind Exposure B – Call your local building department to confirm your requirements prior to ordering.

Roof Snow Load Codes/ Wind Speed Code

  • On the website, you will select from the Codes listed in the drop-down menus in Option 1, 2 or 3.
  • Please contact your local building department or Google codes for your zip code.
  • Choose codes from our list that meet or exceed your requirements for accuracy in pricing online:

Roof Snow/ Wind Speed

 0  lb. S/L/130 mph  

 0  lb. S/L/150 mph

 4  lb. S/L/115 mph

 20 lb. S/L115 mph

 30 lb. S/L 115 mph

 40 lb. S/L/115 mph

 60 lb. S/L/115 mph

More About Roof Snow Loads – Pound per Square Foot

Typical snow loads in the United States can range from 4  to 60+ lbs per square foot depending on precipitation. Obviously, in warmer climates there are 0 lb minimum snow load requirements, whereas, in colder states where snow and ice hardly have a chance to thaw before the next storm, roof snow loads can be greater than 60 lbs per square foot.  In addition, snow tends to drift and accumulate heavier in some spots than others, which is why snow loads are a factor in addition to the standard dead loads of a building.

More About Wind Codes – Miles per Hour

Wind load is also determined by patterns of climate local to your building site. Wind speed codes range from 0 mph to over 160 mph winds.

Wind, unlike snow, will affect different portions of the building not limited to only the roof.  The wind’s effects on your steel building structure will vary depending on your building design and how it sits on your property.  During the software designing process, strength factors are determined by building height, the size and number of large framed openings, and even the location of those openings.

Wind Exposure

Also in relation to wind is the exposure of your building. Exposure B or C is site-specific.  For example, in gusty areas, your local building department may require Exposure C if there are no windbreaks provided by your surroundings, such as trees or neighboring buildings. Wind exposure also affects how snow tends to drift and accumulate on your building structure.

Contact Your Local Building Department Early for Governing Codes, such as IBC – 2015

While your metal building broker will ask you to confirm these codes per your local building department, the MBS (design and pricing software used by your broker) will recall default minimums when the representative enters your building site ZIP code.  In many occasions, the local building department will ask you for higher than minimum requirements and dictate which building code year governs these specifics. For example, IBC 2015 or NCBC 2014 (International Building Code for year 2015, or North Carolina Building Code for year 2014, etc.)  

In summary, contact your local building department to get specific governing year code, roof snow requirement, wind speed requirement, and the wind exposure requirement specific to your building site address and ZIP code.
