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.

Thickness (R-Values)

Thickness/R- Value is a measurement of the effectiveness of an insulated product to retard the loss of heat flow. The thicker the insulation blanket, the higher the R- Value.

Fiber glass thickness Uninstalled R- Value
2” Minimal (primarily used as a vapor barrier)
3” R-10
4” R-13
6” R-19
8" R-25
9.5" R-30
** Double Layer sytems are also offered to achieve high R-Values.

Banding Systems

Banding system (2 layers of insulation) offers 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 structures that are required to be climate controlled.

Retrofit Systems

FOR EXISTING BUILDINGS: Metalbuildinginsulation offers one of the most easy to install retrofit packages available for an existing metal 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.
