Christmas is the Time of Giving and Recycling
I noticed this year, Home Depot is making a big deal out of trying to reduce EPS (“styrofoam”) out of some of they're packaging and just substituting other plastics. They think it is great, I think it is foolish. That new packaged Home Depot Christmas gift that doesn’t have EPS but cardboard and plastic, where does that packaging end up? After Christmas this year, look though people’s trash and you will discover that much of the paper and cardboard that can be recycled is not. Why? What did Home Depot gain?
Let’s talk about EPS for just a minute. There are recycling centers all over the US just for EPS. In fact, there are over 200 EPS collection centers and growing. Last year in 2016, over 118 million pound of EPS was recycled. That is a ton considering EPS doesn’t weigh that much as 98% of the product is air.
They say, Americans are lazy and we need stuff that is biodegradable to put in the landfills. They don’t think we are smart enough or motivated enough to recycle EPS. I think Americans are smart enough but we certainly could do a better job of educating the public on all these EPS recycling centers. We could do a better job of letting the public know that EPS is a resource rather than garbage. That EPS is 100% recyclable just like aluminum cans. We need to push our local municipalities to add Number 6 to our recycle bins. (Click on the Video below, it is really eye-opening.)
So this Holiday Season, I am adding to the phrase “Peace on Earth” to Peace on Earth and please recycle your EPS.

Steady Wins the Performance Race
In high school, I remember watching the track team race around the track. One runner Peter, a farm kid, was fascinating to watch as he always grabbed the early lead. Peter always looked so fast but in the end he would typically finish in 3rd or 4th place. In that moment, early in the race, Peter looked like a world class athlete that would easily win gold at the Olympics. In those early moments, that frozen time, the measure of performance was perfect.
Thirty-six years later and I see the same thing happening in the rigid insulation market. Its like watching Polyiso, and XPS insulation running just like Peter, getting off to a tremendous lead regarding R-value, but then fading out at the end. That perfect moment in time is when that R-value gets measured and they look like superheroes but in reality they just “blowhards.” Pardon the pun as the blowing agent escapes and lowers the r-value. (LEARN WHY)
When it comes to below grade or roofing insulation, Polyiso and XPS start out with really good R-value numbers but they don’t last (LEARN MORE). Unfortunately, you pay for these early performance numbers, sometimes as much as 50% more. Paying for performance isn’t bad but not knowing that the product will fade out is a different matter.
The old idiom, “slow and steady wins the race” really holds true in insulation. EPS might start out slow (or lower r-value) but is consistent through its life and ultimately wins the race. Not only does EPS (Expanded Polystyrene) have a steady consistent R-Value but when compared with XPS and Polyiso, it also performs better in the field. XPS and Polyiso, when wet, hold the moisture and loss much of its r-value. EPS has the ability to hold its r-value and even expel moisture under exsiccate conditions.
Next time, when you’re looking to specify or install insulation on a project, remember that Polyiso and XPS look great at the beginning but EPS is the steady performer and the best value in rigid insulation. Your customer deserves the winner - EPS.
Value Engineering - A Win-Win Strategy
Experience in the industry has shown that it takes designers and architects several years to catch up and change their project specifications based on new information. This opportunity window allows for roofing contractors to provide a wonderful service and offer "Value Engineering." (Get a copy of - "Value Engineering Tips and Tricks for Roofing")
The recent research has shown that polyisocyanurate (ISO) insulation provides an R-value of 5 R/inch at 40ºF and 4 R/inch at 25ºF. Contrast that to Type VIII Expanded Polystyrene (EPS) that has an r-value of 4.2 R/inch at 40ºF and 4.4 R/inch at 25ºF. Now, take into account that the cost difference between ISO and EPS insulation. ISO Insulation can cost up to 60% more. This really spotlights EPS as the best r-value/inch value. Substituting EPS insulation in for ISO in a value engineering premise is quite simple as the numbers speak volumes. The real trick is how it can be accomplished in an environment that is so "Pro" ISO?
Ultimately, the building owner can win by saving money and yet the contractor can win by proving his professionalism and closing more work - a real Win-Win.
The Shrinking R-value of Polyisocyanurate Insulation
The real question maybe why? and why another change after last year’s change? The answer is independent testing. According to research conducted by BSC (Building Science Corporation) and others, “the thermal performance of some insulation materials changes as they age. The R-Value of Polyisocyanurate decreases as some of the gasses … diffuse out and are replaced by air.” This is known by several names - Thermal Drift, Gas Replacement Process or Off Gassing.
What the research has shown is that unlike EPS (Expanded Polystyrene) Insulation that increases its R-Value when the temperature decreases, ISO Insulation R-Value actually goes down. Bottom line: In the north, when you need the r-value the most, its not there like we thought.
Solutions
• If you need to use ISO - the BCS Recommendation is to use it in a “hybrid insulation approach” with a cold stable R-Value insulation like EPS.
• Try to substitute out ISO Insulation and use EPS or the New Neopor Plus Insulation.
