The Best Below-Grade Rigid Foam Available Today!

For many years now the market place for below-grade insulation has assumed XPS is the product to use. However, a recent update to the 40 year old test data has just proven that EPS and Foam-Control® PLUS+® is the superior below-grade insulation in the market today!

For years information from the short term C272 water absorption test within the ASTM C578 quality control standard for rigid polystyrene has been misrepresented by some as long-term performance. This in spite of scientists from the Dow Chemical company stating “that moisture gain in perimeter insulation cannot be predicted accurately by any one laboratory test”. Permeability has been wrongfully ignored as part of the equation. Long-term testing shows significantly higher water absorption rates for XPS, as high as 50% in some studies! While this material is slower to absorb moisture in the short-term, it lacks the permeability to release the moisture it gains. The result is lowered R-Value that does not recover during drying conditions.

Foam-Control® PLUS+® provides superior permeability and R-Value retention when compared to XPS rigid foam insulation products commonly in use today. Just as technology updates have moved us in so many ways from cell phones, computers, automobiles, and products we use daily, so has the technology of heat and moisture transport in building systems.

Building science is no longer looking at the short-term manufacturer quality control measures and now looking at long-term performance. Foam-Control® PLUS+® is the clear winner in long-term building science performance with its superior permeability and long-term consistent R-Value. Other rigid foams such as XPS or Polyisocyanurate do not have the permeability to release gained moisture and are produced using unstable gas blowing agents effectively lowering their stated R-Values.

Foam-Control® PLUS+® Architectural Insulation is the superior rigid foam insulation available in the market today. If you are looking for a stable and predictable R-Value, then Foam-Control® PLUS+® insulation is the choice!

Why Not Tapered EPS?

 

By: Nick Harvill, Sales Representative

Page0001 Roofing Profile View

I recently had an Architect ask me why should they use Foam-Control® PLUS+® Tapered EPS to slope their roofs rather than Polyiso?  My answer was, “Why wouldn’t you use EPS?”

It has been proven by multiple agencies that Polyiso does not meet its published R-Value and the In-Service R-value of Polyiso is actually between 4.6 and 5.0, at 40 degrees mean temperature, even when it is new.  Tapered Foam-Control® PLUS+® 150 is R- 4.6 and Foam-Control® 130 is R- 4.3 per inch.

Tapered EPS can be installed in one layer, eliminating hundreds of squares of application and gluing.  It can be installed over a base layer of EPS roof insulation or Polyiso and a cover board on top.  A three layer system.

The main purpose of the tapered insulation is to provide slope.  Tapered roofing insulation can do that for 30% or more reduced cost per unit compared to Polyiso.  EPS has the lowest cost per R-value of any rigid insulation.

Since the R-value of tapered EPS roof insulation is actually very close to that of Polyiso’s in-service R-value, the R-value tradeoff is minimal or none.  So there really is no advantage to using Polyiso for the tapered layer and it costs more.

EPS Transforms Interactive Playspaces

We all know about the many applications of EPS insulation in the construction fields, commercial, residential, and industrial. We see it used as a very economical insulation delivering a stable R-value on roofs, walls, above and below grade applications. It is used in external insulation finish systems (EIFS) for both walls and architectural shapes and garage door insulation. We even see it used as substrate in place of dirt and backfill (Geofoam). Beyond insulation, EPS is used in packaging such as insulated shipping containers and protective packaging.

An EPS OEM application that many may not be aware of is the use as a structural cavity fill for children’s playground sculptures. Inside that Bug’s Bunny and colorful climbable cartoon tortoise lies EPS.

Playtime Creations in Denver, CO buys EPS blocks and artistically transforms them into works of art and entertainment worldwide. The artists carve, cut, and sand the EPS into the desired shape, then coat it with a durable outer layer that is painted. Every time I stop by their office it is absolutely fascinating to see what their artists are creating and carving in their quest to turn someone’s ideas into Playtime Creations.

Learn How It’s Made in Person with a Plant Tour

By: Joe Kurz, Packaging Specialist

tour

In my free time, I enjoy visiting breweries and wineries. It is enjoyable to sample products that are the result of knowledge, effort and experience by enthusiastic individuals producing these liquid refreshments. Often, a tour of the facility is offered to give us a basis of what it takes to produce the product.

At ACH Foam Technologies, we encourage all of our customers and their staff to take an hour or two out of their week and visit us for a tour of our manufacturing facility. All of our locations nationwide can accommodate these informative visits. You will see, in detail, the entire process of how EPS is formed into many of the everyday products you use. A plant tour is far better than watching an episode of “How It’s Made” on television and give you a better understanding of the knowledge, effort and experience it takes to produce these products used in insulation, geotechnical, packaging, and OEM applications.

Contact us to book a plant tour at one of our nationwide locations.
