Selecting the Proper Metal Building Insulation for Your Needs
In order to select the Metal Building Insulation that will best meet your needs first you need to understand R-Value.
What is R-Value?
R-Value is the measurement of insulation effectiveness to prevent heat loss. The thicker the fiberglass insulation blanket the higher the R-Value.
Single Layer Insulation
Double Layer Insulation
|2 5/8" R-8||6“ and 3” R-29|
|3" R-10||6“ and 3.5” R-30|
|3.5" R-11||6“ and 4” R-32|
|4" R-13||8" and 3" R-35|
|6" R-19||6“ and 6” R-38|
|8" R-25||9.5" and 3" R-40|
|9.5" R-30||9.5" and 4" R-43|
Facing is the material (white vinyl or polypropylene) used as the finished vapor-barrier cover laminated to and over the fiber glass blankets. Click on the facings chart to see specifiations on each facing type.
Tabs are the extra facing material at the side laps of your insulation used to seal or create the finished edge for the seams. 1-6” is the most common in new construction ans 2-3" tabs are common in retro-fit applications.
Single Layer System
Up to 6" R-19 fiberglass blankets can be installed over the top of the purlins in a single layer systems.
Banding systems can be used in a single layer application for retro fit jobs, or in a double layer application for new construction. Double layer systems (up tp R-30) offer the highest R-Values available on our site. You can chose to invest in the upgraded insulation package today (a one time cost), or you can pay the utility company additional money for a lifetime. With the rising costs of energy and the relative low cost of quality insulation, a banding system should be considered for attaching insulation to structures that are required to be climate controlled.
FOR EXISTING BUILDINGS: Metalbuildinginsulation offers one of the most easy to install retrofit packages available for an existing metal building, pole barn or pole building. Factory pre-cut white vinyl faced fiber glass blankets are placed in between the metal roof purlins and held in place by steel strapping called banding screwed to the bottom of the purlin. Your roof purlin spacing can vary but 5’ on center and 8 inches in depth is common (which is the available insulating area). Our 6 inch thick fiberglass retrofit system will brighten any interior as well as provide additional insulating values of R-19. This system is design to achieve the most insulating value out of the available voids created by existing structural components in your building.
