Insulation is invaluable in meeting energy efficiency goals. Under the Energy & Atmosphere category, the credit for optimizing energy performance is worth up to 10 points depending on the level of energy efficiency the building achieves. How much insulation a structure should get depends on building design, climate, energy costs, budget, and personal preference. Building codes specify only the bare minimum; in many cases insulating beyond what the code requires is highly recommended. To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms: conduction, convection & radiation. Conduction is the way heat moves through materials, convection is the way heat circulates through liquids and gases (lighter, warmer air rises; cooler, denser air sinks). Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy. For more info on how Insulation works, visit energy.gov.

A.H. Harris provides industry leading energy-saving thermal and moisture management insulation solutions. We have extruded polystyrene insulation in a variety of sizes and thickness for use in below grade applications, basements, frost protected shallow foundations, concrete floors and slabs, tilt-up walls, precast walls, wind energy, agricultural and livestock buildings, as well as frost protection for roads, railways and other civil engineering projects. An insulating material’s resistance to conductive heat flow is measured (or rated) in terms of its thermal resistance or “R-value” (the higher the R-value, the greater the insulating effectiveness). Extruded Polystyrene Insulation also serves as Vapor Barrier and has an R-Value of 5 per inch. Layering of the insulation can achieve much higher R-10, R-15, and R-20.

Extruded polystyrene insulation plays a significant role in enabling sustainable building design concepts. It provides excellent water resistance and R-value retention in below grade use and protects foundation waterproofing and damp proofing from damage during backfill. We provide extruded polystyrene insulation in a wide range of compressive strengths suitable for virtually all commercial slab applications. Owens Corning FOAMULAR® line, sometimes referred to as pink board, is an excellent choice for use as continuous insulation. FOAMULAR® 250 has a compressive strength of 25 psi maximum that is adequate for non-composite insulated concrete sandwich wall panels. ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation, is the industry consensus standard that defines minimum properties for rigid polystyrene insulation products, both extruded polystyrene (XPS) and expanded polystyrene (EPS). Owens Corning manufactures many variations of FOAMULAR® products and is carried at all A.H. Harris locations. FOAMULAR® 150, ASTM C578 Type X. FOAMULAR® 250, Type IV. FOAMULAR® 400, Type VI. FOAMULAR® 600, Type VII. FOAMULAR® 1000 Insulation, Type V. FOAMULAR® extruded polystyrene insulation is certified annually by Scientific Certification Systems, an independent third party, to contain “at least 20% pre-consumer recycled polystyrene.” The water resistance of FOAMULAR® in PRMA roofing systems enables the design of “green” or “vegetated” roof systems that help manage storm water runoff from sites, helping scoring a point in the Sustainable Sites category.
