Fiberglass Vinyl faced Insulation vs Spray Foam

WMP-VR-R Fiberglass Facing
Spray foam

COST:

One of the most expensive insulation options on the market is Spray foam. Unlike fiberglass, which is a popular DIY material due to its ease of installation, spray foam is far more labor-intensive and usually requires professional application. With a metal building, a layman simply rolls the vinyl-faced insulation over the purlins and girts, then pins it down while installing the sheeting material. Although Spray Foam may offer a higher per square foot thermal efficiency than fiberglass viny faced, one has to consider the additional initial investment required.

HEALTH FACTORS:

One must also consider that the chemicals used in spray foam can release toxic gases if not installed properly. That is not an issue with fiberglass vinyl-faced insulation. It is imperative that one verifies that the space being insulated is well-ventilated and that all safety measures are implemented during installation.

EXPANSION:


Fiberglass Vinyl-faced insulation is not going to expand; however, the nature of spray foam is to expand as it cures. This can sometimes lead to unwanted pressure on  drywall and framing if not closely watched during installation.

Fiberglass Vinyl-faced Insulation vs Reflective

Effectiveness in Cold Climates


Reflective insulation is designed to reflect radiant heat away from your metal building or pole barn; therefore, it is an ideal insulation type in hot climates. Its primary purpose is to keep your structure cool; however, most locations require insulation to address climate conditions for all seasons. In other words, an insulation that also deals with winter temperatures. Reflective insulation has a limited ability to resist heat flow, which makes it less effective in cold climates. For this reason, fiberglass vinyl-faced insulation is a more practical choice.

Airspace Installation Requirements

Simply put, reflective insulation requires a gap to be effective, and there are situations where this may be a challenge during installation. This is not a requirement with Fiberglass Vinyl-faced insulation.

Although all insulation types have their market niche, pros and cons, fiberglass vinyl-faced insulation is the most preferred type for DIY projects. Ready buyers, call 1-888-512-1116.

An Elderly Woman’s Candy Display inspired our Selling Approach.

When I was a child, there was an elderly woman in our neighborhood who never opened her door on Halloween. Instead, she left a bowl of candy outside her door with a handwritten sign: “Please take only two pieces.”

Although I felt tempted, my two brothers and I always obeyed. We understood—intuitively—that the candy wasn’t just for us. It was our responsibility to leave some for the children who came after.

Years later, as I prepared to take my own kids trick-or-treating, I realized no one would be home to hand out candy. So, I did exactly what that “elderly woman” had done many years earlier: I left a large bowl of candy outside the door with a sign that read, “Please take only two pieces.”

As my kids and I walked down the driveway to start trick-or-treating, a group of children rushed past us toward my front door. Then I heard someone exclaim, “Someone left all this candy!” Quite concerned about their intentions, I hurried back to my porch and saw them grabbing handfuls.

I asked, admittedly with some irritation, “Why didn’t you follow the instructions to take only two pieces?” No one answered; however, one young girl quietly returned some candy. The others ignored me and left with what they had taken. When my kids and I returned later that evening, I was pleasantly surprised to see some candy still left in the bowl, which reassured me that there are still those who do the right thing when no one is looking!

Fast-forward to today: Instead of leaving candy outside the door and asking for you to take two pieces, we’re presenting you with the “actual” wholesale price for insulation.

The instructions are still clear:

Leave a “fair” profit.
