EIB uses a variety of insulative systems that create a comprehensive heat transfer/sound attenuation solution. All our steel framed homes are wrapped with extruded polystyrene foam panels that evelope the house like a thermos bottle - leaving no thermal breaks. Inside we use a cellulose insulation, which is made from recycled paper treated with Borates to make it fire retardant. This product is blown into walls for a true R-13 around pipes, wires and blocking to create an insulation barrier free of voids, compaction and misalignment that reduce R-value as commonly seen with fiberglass batt insulation. Attics are blown to R-30. Added benefits include reduced sound transmission, pest and air infiltration with increased fire safety. Cellulose insulation used meets ASTM C-739, the industry standard for fungal resistance set by the American Society of Testing and Materials.

Sensitive to growing concerns about indoor air quality and environmentally-responsible building products, EIB uses Johns Manville's Formaldehyde-free™ building bat insulation. This product has revolutionized the building insulation industry by combining superior thermal and acoustical performance along with healthier indoor air quality. This material is also used on all EIB HVAC duct systems and all other piping that requires insulation.
