Insulation Options

Insulation Blanket Thickness / R-Values
The higher the insulation blanket thickness, the higher the R-Value of the insulation. R-Value is a measurement of the effectiveness to retard or prevent the loss of heat flow.
Single Layer Insulation
2" Not Rated
3" R-10
4" R-13
6" R-19
8" R-25
9" R-30
Double Layer Insulation
6“ and 3” R-29
6“ and 3.5” R-30
6“ and 4” R-32
6“ and 6” R-38
(generally top layer is unfaced)
   
Insulation Facings
Facing materials are applied to fiber glass insulation blankets to serve as a vapor retarder as well as a protected cover over the fiberglass.
   
   

 

 

Tabs

Tabs are the extension of the vinyl facing past the fiberglass insulation blanket, used to seal or create a finished edge for the seams. You can get 1-6” tab on one side of the fiberglass, or 2-3” tabs. Double faced tape can be added to seal the tab to next piece of insulation. In retrofit this is usually 3” on each side and 6" on one side in new construction. In RetroFit, It is either tucked up along the side of the fiberglass acting as a trim or used to cover the the purlin or girt. An option is to get a factory pre-applied adhesive on the tab, which the installer peels and sticks to the next blanket. This provides a clean seal to the seams and creates a vapor barrier.

     
     
Attachment Methods
 
     
Banding
In metal buildings banding can be used to secure metal roof insulation or in the walls (most commonly used in the roof.) Steel bands typically 1” wide are screwed to the underside of the metal purlin (or wood truss in a pole barn) 30” apart creating a grid system. Commonly used in double layer High R-Value metal roof insulation systems and in Retro-Fit insulation applications. To calculate the amount needed, multiply your metal roof square footage x 40%. Rolls are typically 500' long.
     
 
InsulHold
Ideal for new construction where high R-Values are required, or in retrofit to help hold insulation in place and from sagging. Arrows, which are contoured for strength, stick within the fiberglass and provide holding power to the insulation. InsulHold bands are used independently, however, for additional support steel banding, steel liner panel, or an insulation fabric covering such as Energy Saver are optional.

Building Length x 1.02 (102%) ________ x # of Girt Spaces________ (3 shown above)
This Equals the Total Lineal Footage Needed
(Based on 4 Arrows per Strip at 37" Long per strip, installed 36" apart)

InsulHold comes in 100' Long Coils

     
 
Pins
A common way to secure retrofit insulation to the walls is using stick pins. Insulation stick pins are glued to the wall panel 16” apart. The pins then penetrate the fiberglass and facing and a washer is placed over the insulation to secure it. The pointed tips are then cut off with a wire cutter. This application creates a quilted look.
(Pins should be covered in high traffic areas to prevent injury)
