3 Technologies in 1 - SAV+R

Putting insulation on foundation walls just got better. In the past we have put insulation on wall to not only provide R-value but it could help protect the damp proofing and reduce condensation. Insulating the foundation came with a cost as we have learned that standard 150 & 250 insulation is too stiff. Lateral pressures on the walls have increased causing more issues.

SAV+R 3 tech in 1

Plymouth Foam has developed a 3 in 1 insulation board that can reduce issues caused by insulating foundations - SAV+R Foundation Protection™. This new product has been designed to not only insulate but also drain moisture better and reduce lateral pressure by unto 40%.

There are 3 advancements with RID Technology are important in todays construction to not only preform better but also reduce liability. R-I-D Reduced-Insulate-Drain

Reduce - Reduce lateral pressures by up to 40% using SAV+R Foundation. When lateral pressure pushes on the SAV+R foundation board, the integrated Stress Reducers™ can “absorb” this pressure and help save your foundation from failure. SAV+R has been designed to handle backfilling pressures, compacting pressures, clay or soil swell pressures and long-term lateral pressures.

Insulate - SAV+R uses Engineered EPS which provides a stable R-value for the life of the foundation. SAV+R is available with R-values of 5, 10 or 15. SAV+R Engineered EPS does not leach harmful chemicals into soil, has very low moisture absorption, is not affected by the freeze-thaw cycle, contains no ozone depleting chemicals and is 100% recyclable.

Drain - Water leaking into foundation walls via hydrostatic pressure can cause serious issues. SAV+R incorporates Easy Flow Drainage Pathways™ (EFDP) to move water quickly to the foundation drains. EFDP can help reduce insulation moisture absorption, reduce hydrostatic pressure, reduce frost heave, accelerate drying and can add longevity to the waterproofing.

Change Is The One Constant - XPS Insulation Does Like It

Every year at this time, we ask ourselves what the changes are going to be in the construction business. Prices, labor, materials or codes seem to be constantly changing. What worked last year may not for 2021. Throw in Covid and no wonder we are all stressed. What bothers me is when you know there is a change but it takes week or months (years) to sort through and really figure out how the change effects the way we do business.

New Laws for Insulation

I have one of those changes for 2021 and it has to do with XPS (Extruded Polystyrene) Rigid Insulation. This is one of those changes that could be very disruptive in the market. Here is the change — the government is mandating that XPS blowing (hydrofluorocarbon HFC-134a) agent be changed to something that is a little safer. The XPS industry has known this has been coming for a long time and has done many things to try and slow it down. They have been successful at getting several reprieves.

Why is there such push back from the XPS Rigid Insulation Industry? Isn’t reducing “harmful” chemicals into the atmosphere and reducing global warming a good thing to help with climate change? It is unless it changes the effectiveness or stability of your product. That is why the XPS industry is fighting so hard. Whether they will admit it or not, this EPA rule change for blowing agents will result in dramatically lowering the XPS product effectiveness.

As mentioned it takes time to sort out all these changes. We do know that the alternative blowing agents will reduce the R-value of the product to be more in line with EPS (Expanded Polystyrene). XPS has always claimed that its R-value is 5R/inch. Some reports have the new XPS coming in at 4.3R - 4.5R per inch. It will be interesting to see if the XPS Industry will be truthful about the R-value change. They have billions of dollars at stake.

The other element is the stability of the product. Will it shrink more? Will it collapse? What happens long-term below grade? Will water affect it differently? What about flammability? Some elements will be seen right away, others may take years to sort out. No wonder the XPS Industry is pushing back so hard. It is a scary time for them. I have even heard rumors of a manufacturer stock piling old formula product to buy more time to figure things out.

With all these changes, what should you do? Not knowing what you are going to get for XPS it is probably wise to use the “Safe Insulation” - Engineered EPS. Yes, it has a lower r-value per inch (4.35R/inch Type IX) than old XPS but you know exactly what you are getting. You know that Engineered EPS Rigid Insulation is safe and stable. (Learn more about Engineered EPS Insulation) For some, the change may mean shifting over to EPS but that maybe a very good change for your business.

Roofers: Help Your Customer and Make More Money Part 1

Help to Be More Profitable

With the economy booming, it would seem logical that making money being a roofing contractor is simple, but the reality may be much different. A robust economy produces a tighter labor market, and you may find the battle for bodies to be exhausting. Material components are rising as well, and it is challenging to keep up. Finally, controlling risks in one of the riskiest businesses can, at times, be overwhelming.

Interviewing successful contractors around the country, has led me to share one simple approach to making more profit on roofing projects. Many cost factors in the roofing process are out of control of the contractor. One secret approach that these successful contractors use, is -
value engineering the specification. Many roofing contractors are afraid of the “Written in Stone Specification.” They believe it is difficult, if not impossible, to get changes. This concept is key.

Roofers Help your customers and make more money

Value engineering the specification is all about positioning yourself and your company as an asset to your customer, whether it is the General Contractor, Architect or Building Owner. Learning and developing roofing expertise will allow for you to offer better value to the end user. I am a firm believer that a contractor should get paid extra for bringing better value to a project. That is what a true Roofing Professional is all about.

The approach is to offer Engineered EPS Insulation on every project. Each insulation has its positives and negatives, but Engineered EPS Insulation has numerous advantages over Polyiso. (
See ISO VS EPS) The bottom line is EPS has many more advantages over Polyiso and (Get up to speed on Engineered EPS in Roofing) the Value Engineering numbers are significant.

Examining a standard $200,000 roofing project shows that the savings is generally around $9,600 - $10,200 changing to EPS, yet keeping the same R-value. That savings can be shared with the account 50-50 and the result is a margin addition of roughly 2.5%. If your a $5 million a year contractor, 2.5% would add $125,000/year in profit.

Knowing the numbers is one thing, but implementing an action plan, if you’re not experienced at it, can make this approach a challenge. Plymouth Foam can help and your customer will love it.

Foundation Problems Part 1: Uncovered and Solved

Foundation Problems: What is the cause, what is the solution?

For over 10 years, we have been studying the effects of foundation issues - why do they crack, why do they leak and what is the real source of the issue? In fact, it is now estimated that foundation problems cost insurance companies between $12-15 Billion annually in the US. Is insulation playing a part in the mystery?

SAV+R Introduction- Something Big is here

Foundation issues have long plagued the construction industry. This is evidenced by the fact that the basement and foundation repair industry has grown double digits for the last 10 years. Is it a coincidence that foundation cracks have increased even more with additional R-value requirements? The effects of foundation issues can be bulging foundation walls, moisture leaking, structural issues, mold, strange odors, cracks in drywall, window and doors not opening/closing properly and even pest invasions.

What is causing all these issues and what can be done about it? Through a series of 5 technical articles over the next several months, we will explore the major reasons for all these issues and what can be done.

It is good to know that through all this research, Plymouth Foam has developed a new product that can help reduce foundation issues before they start - we call it SAV+R

Give Me Some Skin - Understanding Insulation Specifications and the Skin Pitfalls

Many building professional spend hours looking over drawings and specifications for upcoming building projects. Many look closely at the type of product or the brands allowed but tend to glance over the other supplementary or extraneous information.

A few weeks ago, I noticed an item in a foundation specification that I have been glancing over without any real thought.
“Rigid, cellular thermal insulation with closed-cells and integral high density skin, complying with ASTM C 578.” What caught my eyes was integral high density skin. Are they trying to call out a specific for Extruded Polystyrene (XPS) Insulation because standard Expanded Polystyrene (EPS) would not naturally have a skin without adding it?

This triggered a technical conversation about skins on Rigid Insulation.
Does rigid insulation need a skin? What are the advantages or disadvantages of having a skin?

XPS Give me some skin

It is always helpful to go back and review the main function of insulation. Insulation’s main purpose is to insulate and provide R-value. Knowing the main purpose of insulation, do insulation skins provide more R-value? Skins can add R-value and skins can reduce R-value. A foil faced insulation could add R-value when it is used in the right circumstances such as a gap behind a masonry wall. Some skins like a clear poly laminated has no effect on R-value. Does an integral high density skin in XPS offer additional R-value? No, in fact according to newer research, it may have the opposite effect. How can this be? Why specified it as something important?

During a manufacturing process, XPS creates a type of skin during the extruding process and some call this an
integral high density skin. This skin is maintained on the face and back of the board but the sides and the ends are trimmed during the manufacturing process. Many believe that trimming the sides actually expose and opens the board to moisture infiltration at a higher rate. The face and back have this skin but the ends and sides are open. Interesting, when you consider below grade insulation and how water moves down the foundation wall, water hits the top part of the insulation and water wants to enter in, however the top end does not have the integral high density skin. We know by testing, when XPS insulation is installed below grade, it takes in moisture and its R-value is reduced by 48%, from 5 R/inch to 2.6 R/inch. Some believe this phenomena is caused by water entering in easier at the edges and partially trap in by integral high density skin. So specifying this integral high density skin as a benefit, ultimately points out another reason not to use XPS below grade. Why pay a huge premium for XPS Insulation and get 1/2 of its R-value performance?


What about skins on EPS? Standard EPS does not naturally have a skin, however another advantage of EPS Insulation is that skins can be added. Many different types of skins with different properties can be added. A few examples of skins are ones that can be reflective, skins that allow permeability, skins that are vapor retarders and even skins that can provide high strength. In foundation insulation, where EPS is more effective, a permeable skin could be added to give even more strength. This skin could be even more effective against rough backfilling and fastener pull. This type of product would function great allowing any moisture that enters into to the insulation board to flow freely out and not trap the moisture in.

In this case, the specifier thought that XPS insulation with an
integral high density skin would be a better product for below grade application. Unfortunately, it's not. With research showing that XPS insulation can loss 48% of it’s R-value below grade, Engineered EPS Insulation is a much better, safer choice.

EPS and SIPs - Go Together Just Like Peanut Butter and Jelly

The performance record of Structural Insulated Panels (SIPs) have elevated them to be the top wall and roof structural system on the market today. No other system offers energy efficiency with such ease of design and installation.

Many contractors have an impression that SIPs are hard to install or are expensive. Someone has given them bad information. Let’s explore the real truth about Structural Insulated Panels.

Expanded Polystyrene (EPS) SIPs account for about 90% of the SIPs market. EPS SIPs is one of the easiest and quickest energy efficient structural systems that is available and code approved in the United States. Notice, I said, “EPS SIPs.” EPS SIPs are easy to install.

SIPs design economical fast


What can make installing some types of SIPs more difficult? The difficulty of “field modifications” such as a window opening change. For the EPS SIP, modifying a window opening (example: moving it over 2 inches) is fairly simple. The foam and OSB is easy to cut and move. What makes EPS SIPs so simple is the that the foam is easy to manipulate and cut. Even installing electrical wiring through EPS SIPs is extremely easy.

The people that may say SIPs are hard to install are most likely talking about urethane SIPs - the yellowish insulation. Yes, this type of SIPs panel are harder to work with as the insulation is hard to manipulate and modify. Modifying electrical wiring is also very difficult. The bottom line is very few of these Urethane SIPs are sold. It is probably best to stick with EPS SIPs and avoid the hassle.

Finally, what about SIPS being expensive? EPS SIPs are not expensive, most of the time they are misunderstood. (
Click and review the five elements of SIPs cost) No other structural energy efficient system on the market is faster to install and more economical. Studies have show that to get the same performance from other systems, many more steps are needed and they are never quite as good.

If you have never tried using SIPs before or it has been a long time, this may be the year that you discover what makes them so impressive.

Metal Roof Retrofits- Insulate the weakness?

For many customers, metal roofs were to be the end all to roofing problems. Unfortunetly, I see 1000's of building owner trying to solve their metal roofing leaks.

The most popular solution is adding some insulation and retrofitting a new roof membrane over the top. This is were roof insulation
Flute Fillers play an important role. Not only do they add R-value to the system but they can transition a flat surface for a new roof retrofit system. I typically see flute filler level with the top of the ribs/seams and one additional layer on top of that smoothly bridging the top of the ribs/seams. The question is can this system be improved upon?

The one area of thermal weakness in this system is where the original metal roof has seams (connection point of the two pieces of metal roof) that allow heat loss at those points. By installing only one layer of insulation over these seams, it allows for the potential of thermal loss at these junctures were the insulation joints meet these metal roof seams. This thermal loss could cause condensation and stress the membrane disproportionately causing future issues.

Metal Roof Retrofit Weakness Metal Roof Retrofit Weakness with system


Some may say, there is insulation under the metal roof system already, those joints don't leak heat. Really? Take an infrared camera and scan that metal roof and look at the seams, you might be surprised what you find.

There are two solutions to fix this potential problem with retrofitting over a metal roof. The first solution is to add another layer of insulation and offset the joints. The second solution is to use
Plymouth Foams RetroDeck™ with a cover board. This system has a built in seam offset. No roofing system is perfect, but eliminating as many potential problems can help a roof system last longer creating better value for our customers.

EIFS What To Know: Increase your knowledge and lower your risk.

The fastest way a construction contractor can increase their risk on a project is to not staying in control of knowledge of a building system - especially high liability systems.

You’re bidding on a project and EIFS (Exterior Insulated and Finish Systems) is specified in the building package. Who do you rely on that it specified, bid and installed correctly? Where does the buck stop?

EIFS has make huge advancements in technology, systems and installation details. The biggest advancement for our northern climates has been drainage or moisture management. Advanced design EIFS systems use a drainage cavity to move unwanted moisture out. This concept is monumental and removes many of the old design flaws with EIFS.

Here is where knowledge can lower your risk and pay off for you.
Insist that your EIFS system only uses EPS insulation. Why?

Lower Your Risk


Good building practices and todays advanced EIFS systems' goals are to discharge any stray moisture as quickly as possible. What about when that moisture finds its way into the insulation? Good Question! We know from
studies that XPS (Extruded Polystyrene) insulation has a difficult time discharging moisture. Moisture in EIFS systems can cause serious system failures such as cracking, blistering, peeling paint, structural rotting and even mold. EPS (Expanded Polystyrene) insulation, on the other hand, has the ability to breath and release off moisture much quicker. In test situation, EPS also has the ability to hold most of its R-value, where XPS losses 48%.

EPS Moisture management is a great reason to insist on EPS insulation in your EIFS system but here are a few more:

  • EPS can be made into a variety of shapes
  • EPS can be made in various thicknesses
  • EPS can be made in various densities
  • EPS offers a consistent R-value
  • EPS is the Safe Insulation - no harmful HFCs
  • EPS is 100% Recyclable
  • EPS is a Better Value and Lower Cost

This is one of those cases where a less expensive product is much better and can lower your risk.

The Perfect Continous Insulation System

The push for higher energy efficiency in commercial buildings is growing, driven in part, by the new energy codes. Another factor has been the Department of Energy studying of R-value in various wall systems and disseminating that information. The study called “Whole Wall R-value,” has lead to a better understanding and promotion of Continuous Insulation.

Continuous Insulation, is defined as, “insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings.” More important is the fact that Continuous Insulation increases R-value performance due to the non-interruption of wooden or steel studs.

Gold-Wall Cut Away Drawing 2

“Furring out” a wall with studs or furring strips and then filling in the gaps with insulation is still a common method used on interior and exterior walls. Every stud used, lowers the R-value and thermal loss and/or thermal bridging occurs at this intersections. Advancement in understanding performance R-value through continuous insulation has lead to the importance of Gold-Wall. The advantage of Gold-Wall is not only a Continuous Insulation system, but it has the built in ability to allow for finishing attachments. These finishing attachments can be interior drywall or exterior clad siding like vinyl or steel. The possibilities are almost endless.
Gold-Wall, with its built in surface attachment stud, can be installed easily to most type of masonry walls. Gold-Wall can also be attached to steel studs, wood framing or even OSB/Plywood surfaces. Gold-Wall comes with a high performance poly facer laminated to the moisture resistant EPS foam board which increases durability, fastener holding and impact resistance.

Gold-Wall may be perfect for your next Continuous Insulation project.
