Fiberglass R-Values and Staple Tab Foil Insulation
This entry was posted on June 2, 2011.
At InsulationStop, we supply radiant barriers and reflective foil insulation. Our products are used as stand alone insulation in certain applications or in conjunction with other insulation types such as fiberglass.
Fiberglass insulation is the most common type of insulation in residential construction and comes in either batt or roll form. Batts are pieces of fiberglass insulation you install one after the other, generally in attic spaces. Rolled fiberglass, as its name implies, is sold in rolls that you cut to length to fit the wall, ceiling, or crawlspace cavity you are insulating.
Both of these fiberglass types are available in a wide selection to fit your particular application. The thickness of the insulation determines the R-Value. This ranges somewhat by manufacturer but is typically 2.9 to 3.8 per inch.
The table below is a quick reference for you to easily compare fiberglass R-Values with their corresponding thicknesses.

|Thickness in Inches|
|R-15||3 ½" High Density|
Our unique Staple Tab Foil Double Bubble Insulation is designed with the same widths you need to insulate in walls, ceilings, crawlspaces, and floor joists. It can be installed with or without fiberglass insulation depending on your application. The unique "Staple Tab" enables you to staple the sides of the product either on the face of the stud or joist or to recess the insulation in the stud or joist cavity, installing the same as you would fiberglass insulation.
We hope this information is helpful. At anytime during your project you have questions, please don't hesitate to contact us. Thank you for shopping at the InsulationStop, your leader in radiant barrier and reflective foil insulation.
