Some of our clients have gotten information from various metal building suppliers on what was referred to as R-8 vinyl insulation – reported to us to seemingly be used to insulate non-insulated metal buildings.
One client’s intent was to use this product to insulate the walls of his new pole building.
The metal building supplier referred to the product as VRR-Plus Metal Building Insulation. I typically ask my customers several questions. First, what kind of warranty does the thin plastic drop ceiling have? If the answer is less than a lifetime warranty, that means there is a good chance you’ll have to replace the material in 10 to 12 years at your great expense. If you ask your contractor why they are recommending fiberglass as insulation, the answer you’ll usually get is, “It’s been used for decades.” The problem with that answer is that technology has advanced tremendously in all fields as well (and especially in insulation applications) over the last 30 years. If they say, “It’s the least expensive,” that means it’s the least expensive to the contractor – and believe me when I say that he’s getting a hefty profit margin from the install. What is he going to say when your building develops a leak and most of your insulation is destroyed?
Oh… and don’t let this footnote slide by: “NOTE: Condensation blanket is NOT sold as a thermal barrier. The insulating value of the product is negligible and should NOT be utilized in conditioned or semi-conditioned buildings where thermal performance of any degree is required.”
There are many other options for your metal building besides the frail MBI VRR Plus fiberglass insulation at a comparable cost.
We recommend Polyshield TRIPLEX MBI R21, which is one of those state of the art options..
The durable TRIPLEX MBI R21 metal building insulation is not as frail as other insulation, as it is engineered to have a lifetime warranty.
TRIPLEX MBI R21 provides an R10 when installed with no air gap, and an R-21 with just 3 inches of air space.
