A Guide to Below-Grade Insulation and Moisture

Originally posted online at Buildings.com in Buildings Buzz!

OLYMPUS DIGITAL CAMERAWet insulation is ineffective insulation – rigid foams that retain high volumes of moisture lose about half of their insulating R-value. Because insulation installed on below-grade building foundations and under concrete slabs is often exposed to moist soil, it is crucial to choose an insulation that has minimal long-term moisture retention and the ability to dry quickly.

For facility professionals that are evaluating insulation for building retrofits or for new construction, paying attention to moisture performance helps ensure effective long-term thermal resistance. Because the insulation will be hidden from view, any problems with degraded materials will not be obvious, although the effect on higher energy bills will be very real.

One challenge in selecting insulation is cutting through the competing claims of insulation manufacturers. Producers of extruded polystyrene (XPS) and expanded polystyrene (EPS) – common below grade insulations – both claim that their products are superior at resisting moisture. In their own ways, each one is right, but it depends on whether one is looking at abstract, standardized tests or performance in actual installed conditions.

Claims that XPS insulation absorbs less moisture than EPS are based on ASTM 272Standard Test Method for Water Absorption of Core Materials for Sandwich Constructions. This test calls for fully submerging an insulation sample in water for 24 hours, then weighing it for moisture absorption immediately upon removal from the water.

How does this test represent reality? The truth is it doesn’t reflect real-world conditions for two reasons:

1) Unless your building is in a lake or river or subjected to severe flooding, the insulation will not be fully submerged.

2) It doesn’t account for how much an insulation dries out or does not dry out between periods of moisture exposure.

Entire marketing campaigns have been built around this test, but when it comes to what really happens on your building, it’s necessary to look at actual exposure during in-situ tests. Studies of insulation exposure to moisture in actual field conditions show that EPS outperforms XPS by a wide margin, largely because EPS dries much faster than XPS.

For example, the independent lab Stork Twin City Testing evaluated the moisture content of EPS and XPS buried side-by-side for 15 years on a building foundation in St. Paul, MN. At the time the insulations were removed, the EPS was four times drier than the XPS – the EPS had only 4.8% moisture by volume compared to 18.9% moisture content for the XPS. After 30 days of drying time, the EPS had dried to only 0.7% moisture by volume, while the XPS still contained 15.7% moisture.

The high moisture absorption of XPS is further seen in a 2012 report from the U.S. Department of Energy’s Oak Ridge National Laboratory. Researchers found that XPS insulation installed below grade for 15 years had absorbed 67% or more moisture. The resulting loss of energy savings performance for the XPS was 10% for a full basement (“deep basement”) and 44% for a slab-on-grade installation.

Insulation manufacturers are well aware of how their products will perform over the years. Evidence of this is seen in the limitations stated in warranties they offer. This is why XPS manufacturers typically warrant only 90% of the insulating R-value of their products during time in service, whereas most EPS manufacturers warrant 100% of the R-value. Some XPS manufacturers will also void warranties in case of ponding or water immersion, which runs contrary to their highlighting of 24-hour, full-immersion testing.

There are many claims in the market about whether EPS or XPS offers the best moisture resistance. When evaluating such statements, it is important to consider the basis upon which the statements are made. Does the testing involve guys in lab coats dunking insulation into a fish tank for one day, or does it replicate how insulation performs on actual buildings over many years? If facility managers are making the investment in insulation, this is an important distinction to pay attention to, otherwise the product might not perform as desired.

With five Baltimore area locations, 36-year old bike retailer Race Pace Bicycles isn’t slowing down.  The company’s Ellicott City store, will soon to be relocated to a nearby site at the junction of Centennial Lane and Route 40.  This location houses its retail operation that caters exclusively to women. Called Bella Bikes, the women’s store was the first of its kind in the U.S. when it opened in 2008.

Insulfoam R-Tech was used as the exterior wall insulation for the building’s metal wall panel system , 20 psi, 2″ x 4 x 8 Sheets.  The benefits of R-Tech as an exterior insulation are important:

  • R-Tech has a dense foam structure
  • Water-resistant film skinned surface
  • Integrated weep channeling
  • R-Tech offers a natural barrier against water in any form
  • Air infiltration and moisture penetration are eliminated
  • Thermal bridging and thermal shock is greatly reduced.
  • R-Tech combines versatility and durability for a complete long-term working system.

The Race Pace project has been a beauty and we would like to thank all that have been involved:

Insulation Choices: EPS or XPS?

Originally posted in Concrete Construction

As a specifier, architect and contractor….you must make well-informed decisions when it comes to below-grade, under slab, and cavity wall insulations in your projects.  Below are two informative articles listing the similarities and differences between both EPS (expanded polystyrene) and XPS (extruded polystyrene) insulations.

Insulation Choices:  Whether to use EPS or XPS can be a matter of cost.

EPS insulation helps reduce heat loss through concrete foundations and floor slabs.

EPS insulation helps reduce heat loss through concrete foundations and floor slabs.

What’s the difference between XPS insulation and EPS insulation, other than a single letter? For installation on concrete foundations and under floor slabs, the rigid foam insulation you choose can make a difference of tens of thousands of dollars on a project. A careful evaluation of these materials’ performance attributes against the project’s needs can dramatically shrink labor and material costs. The savings could mean the difference between a profitable job and one you just have to chalk up to experience.

When it comes to concrete and insulation, contractors tend to be most familiar with extruded polystyrene (XPS). Yet, expanded polystyrene (EPS) performs as well or better than XPS, and at a substantially lower cost. Below are three important factors to consider when comparing these two insulations for any belowgrade or under-slab applications, read FULL article to see more side by side comparisons of EPS and EXP for these insulation factors:  1.) Compressive strength  2.) Moisture retention  3.) Insulating capability.

In the push to forge more energy-prudent builders, design professionals are leaving no part of the envelope unexamined.  Walls and roofs have always presented a clear target for better thermal performance.  Somewhat less obvious are surfaces that are out of sight – below-grade foundation walls and floor slabs.  Well-engineered insulation in these locations can provide significant energy savings.

What separates below-grade insulation types from one another?  Moisture retention, R-value stability, and compressive strength are the key performance attributes to consider when evaluating and comparing different below-grade insulations.

Installing thermal insulation on below-grade foundation or perimeter walls and under slabs is important because un-insulated concrete provides a thermal and moisture bridge between the heated building interior and the relatively cooler earth surrounding the building, or through exposed slab edges to the outside air.

“While insulation strength is important consideration, erroneous design assumptions can lead to over-engineering for compressive resistance, adding unnecessary material costs.” – Ram Mayilvahanan, Insulfoam Product-Marketing Manager

With increasing focus on high-performance building envelopes, it is hard to believe insulation once involved layering mud between logs, stuffing old newspapers into wall cracks, or using other ad hoc methods to seal air leaks and keep heat inside structures. Today’s building professionals can choose from a wide range of insulations, but this proliferation of choices makes selecting appropriate insulation products more challenging.

Rigid-foam insulations are now a mainstay of energy-efficient buildings, whether commercials, institutional, or residential. Products in this category include expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate (polyiso). Careful attention to product attributes in field applications is needed to ensure high thermal performance at a reasonable cost.

Rigid Foam Insulations for High-Performance Building Envelopes

Keeping the Outside Out and the Inside In:  A look at rigid foam insulations for high-performance building envelopes

By Ram Mayilvahanan, Insulfoam Product Marketing Manager

ConstructionCanada_coverIf the concept of building science could be distilled to one essential sentence, it would be the now-famous aphorism of Joseph Lstiburek, PhD, P.Eng., building science expert and adjunct professor of civil engineering at the University of Toronto.

“The perfect wall is an environmental separator- it has to keep the outside out and the inside in,” he wrote .

Lstiburek’s “perfect wall” (or roof or slab) includes four primary layers:

  • rain control;
  • air control;
  • vapour control; and
  • thermal control.

For the last category, specifiers can select from numerous insulation types; fiberglass batts to spray foam and rigid foam boards, as well as integrated systems such as structural insulated panels (SIPs).  This article examines the various performance attributes and product options for expanded polystyrene (EPS) insulation in high-performance building envelopes.

New Product Release: continuous insulation for combustible decks

Press Release originally published in Healthcare Facilities Today

Insulfoam, a leading supplier of engineered insulation products, is pleased to announce the development of InsulFoam HD Composite, a continuous above deck insulation, for use on combustible decks.

InsulFoam HD Composite consists of a closed-cell, lightweight, resilient expanded polystyrene (EPS) bonded to a high-density polyisocyanurate cover board.  This product achieves a UL Class A rating on a combustible deck without gypsum or any other coverboard, and since it is continuous above the deck, it satisfies Title 24 requirements at a lower R value.

InsulFoam HD Composite offers significant cost savings over other cover boards and traditional insulations, and is a very effective insulator – since it is installed above the combustible deck, there is no interruption due to joists.  Its lightweight, factory-bonded panels make installation easy, it is compatible with all fully adhered or mechanically fastened EPDM, TPO, and PVC membranes, and it has a UL Class A rating for combustible and non-combustible decks.  InsulFoam HD Composite will meet or exceed the requirements of ASTM C578 and is an excellent choice for new or retrofit applications where high thermal efficiency and maximum durability are necessary. It is available at Insulfoam locations across the country.

What Compressive Strength Do You Really Need?

EPS:  THE FOUNDATION FOR MOISTURE PROTECTION & INSULATION
 
Many projects design & build for higher load bearing densities then are required, thus costing significantly more time and money than is necessary.  ASTM’s D6817 is the specification for rigid cellular polystyrene geofoam. Designing to this standard not only helps engineers meet technical specifications, but also helps save money and time by using EPS (expanded polystyrene) geofoam, which is listed by the standard, as a structural void fill.  Geofoam has the compressive strength to bear heavy loads like concrete slabs, soil overburden, highway trucks and even airplane traffic and has gained widespread acceptance in load-bearing applications with federal and state entities like DoTs, airports and commercial projects.  
 
Similarly referring to ASTM C578 (Specification for Rigid Cellular Polystyrene Thermal Insulation) while selecting your below-grade insulation products, not only helps you design the right product for the job, but also helps avoids unnecessary costs associated with over engineering. 
 
ASTM C578 publishes compressive strength, deformation and dimensional stability values for both EPS & Extruded Polystyrene – XPS. Insulfoam’s wide range of plain and coated-facer insulation products meet ASTM C578 specifications, providing the same compressive strengths and long-term moisture prevention as competing below-grade insulations. But Insulfoam products come at a lower cost to the building owner, helping deliver significant savings in project costs.
 
FEATURED BELOW GRADE PROJECT: 49er’s Stadium
  • Project:  San Francisco 49er’s New Football Stadium
  • Location:  Santa Clara, CA
  • Product:  Insulfoam GeoFoam 2,500 cubic feet of EPS39 and 25,000 cubic feet of EPS15
  • Application:  Below grade structural void fill to support foundation for the fan seating areas

EPS Geofoam

EPS Geofoam

The contractors (Conoco Company of Concord and Turner & Devcon Construction) chose EPS Geofoam due to it’s extremely low weight and high load-bearing capacity to support the dimensional stability required for concrete topping slabs.  Insulfoam’s multiple manufacturing locations in California and nearby states provided just-in-time deliveries direct to the job site, which was a welcome bonus.

The single largest benefit to concrete contractors when using EPS is the ability of the material to constitute half of the form and the fill simultaneously, which completely eliminates the concept of a two pour operation. Read the full project profile here:  San Francisco 49er’s Find EPS Geofoam Useful In Future Home.

 

DID YOU KNOW?

  • Geofoam is 98% lighter than traditional fill
  • Geofoam does not settle
  • Geofoam eliminates lateral stresses from retaining structures
  • Geofoam can be designed for seismic forces

All Insulation is NOT Created Equal

EPS IN BELOW-GRADE APPLICATIONS?

Yes, when using engineered EPS products that are made in strict accordance with ASTM standards for below-grade insulation.

FACT:  All insulation is NOT created equal.  As a guide when choosing the right insulation product and manufacturer for moisture protection and thermal insulation, refer to ASTM C578. This third party standard establishes the minimum physical properties and requirements, and is the industry’s consensus standard for BOTH expanded (EPS) and extruded (XPS) polystyrene. For example, not all EPS manufacturers can produce 40 or 60 psi insulation in accordance with ASTM C578; Insulfoam does – it makes both products across its US locations.

Cold Climate Housing Research Center uses EPS Foam to Save on Costs & Energy

Written by:  David Shong, Insulfoam Architectural & Engineering Technical Specialist

CCHRC Expansion, Alaska

CCHRC Expansion, Alaska

The Cold Climate Housing Research Center, CCHRC, in Fairbanks, AK constructed an addition to their facility in the spring of 2012.  The project Engineers specified 12″ of InsulFoam GF EPS39 which has a minimum compressive resistance of 2,160 psf @ 1% strain as a sub-base and below slab insulation.  EPS39 was placed around the perimeter under the exterior wall footings and within the zones of influence of interior columns that required higher bearing capacity to withstand the axial loads of the walls,roof and snow load.

The rest of the areas that were simply supporting the 6″ floor slab used 12″ of EPS22 (1051 psf @ 1% strain).  They were originally considering only 9″ of EPS46 (2,678 psf @ 1% strain) for the entire building footprint, but were happily surprised to hear the idea of using a lower density under the floor slabs where the decreased dead loads justified a lower EPS density.

They ended up being able to install 12″ of EPS under the entire footprint for less than the original budget which provided more insulation while saving on initial costs as well as long term energy expenditures.

Saving money with EPS Insulation

Did you know that hospitals spend more on energy per square foot than all other building types (except for food service and food sales)?  And U.S. schools spend more on energy each year than they do on computers and textbooks combined.  So how do hospital and school facility managers, architects and contractors find ways to lower energy usage costs?  Given that heating and cooling account for a large share of electricity and natural gas consumption in buildings, insulation is crucial for energy efficiency by keeping heat/cool in and out via the right type of building and roof insulation.  There are many insulation types, Facility Management and Insulfoam’s Director of Sales and National Accounts, John Cambruzzi, outline why expanded polystyrene (EPS) is growing in popularity by reducing material and labor costs while meeting energy efficient goals for hospitals and schools.
