APS

APS Food & Nutrition Services Kitchen & Storage Warehouse, R-Tech Installation

Albuquerque Public Schools (APS) in New Mexico have been undertaking a massive classroom and educational rebuild and remodel.  All new construction has been designed using sustainable materials and energy-efficient principles with LEED certification as the end goal.

As part of new buildings under construction is a 108,000 sq. ft. central Food and Nutrition Services Kitchen and Storage Warehouse.

Originally specified XPS was replaced with Insulfoam R-Tech VI 40 psi over the sub slab freezer floor.  The project utilized 2 lifts of 3″ R-Tech instead of 3 lifts of 2″ XPS ultimately saving the  concrete contractor approximately $20,000 in material costs.

Long-term is the Right term – LTTR and Insulfoam Insulations

Insulfoam SP Roof Insulation

Insulfoam SP Roof Insulation

Long-Term Thermal Resistance (LTTR) rocked the building world in early 2014 with the announcement of lowering R-values for a number of insulation products – products that lose stability over the longer term.  But NOT Insulfoam insulations.

  • During manufacturing, Insulfoam does not use any ingredients that degrade or destabilize over time
  • Insulfoam insulations DO NOT lose R-value even over the long-term, a characteristic that has been verified by independent long-term testing

With Insulfoam, you get what you pay for: an insulation product that retains the same R-value when first purchased.  Which is why Insulfoam insulation is backed by a LONG-TERM thermal warranty.  For more information, contact your local Insulfoam rep.

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

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

  • 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.

BELOW-GRADE INSULATION PROJECT FEATURE

Starwood Hotel Finance Headquarters

Starwood Hotel Finance Headquarters

Rouser Concrete, the concrete contractor for the Starwood Hotel Finance Headquarters project in Arizona, chose Insulfoam R-Tech due to its superior performance as a durable and stable under-slab insulation which came at an economical price- great value for money.

During construction, the surrounding high-end retail stores were open for business, making it difficult for trucks to get in and out with product.  And storage space was at a premium.  Insulfoam’s Phoenix plant stepped in as a ‘local’ manufacturer with Just-In-Time, delivering however much product was needed at the jobsite at a given time.

Insulfoam R-Tech

Insulfoam R-Tech

  • Project:  Starwood Hotel Finance Headquarters
  • Location:  Scottsdale, Arizona
  • Product:  R-Tech 10, 65,000 Sq. Ft.
  • Application:  Under Slab

WHAT MAKES R-TECH EPS AN EFFECTIVE BELOW-GRADE INSULATION?

High compressive strength and engineered facers on both sides make R-Tech the most versatile combination of performance and economy.

  1. COMPRESSIVE STRENGTH- high compressive resistance that can be tailored to the loading requirements of the job
  2. MOISTURE PROTECTION- comparative study shows R-Tech has very low long-term moisture retention with no detrimental effect on its physical properties
  3. THERMAL STABILITY- long-term, stable, and warranted R-value that does not drift
  4. BEST R-VALUE PER DOLLAR- of comparable rigid insulations
  5. NATIONWIDE PRESENCE- manufacturing locations throughout the US

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.
