Guide describing methods for insulating an unvented crawlspace or conditioned basement with rigid foam on the interior side of the walls to provide an insulated space for HVAC equipment.
Guide describing how to upgrade a wall with a floor overhang (or cantilever) on an existing home by adding insulation (rigid insulating sheathing and/or closed-cell spray foam) and air-sealing.
Guide describing how to insulate a basement to improve the overall thermal performance of the building and provide more dry, usable conditioned space for home occupants and HVAC equipment.
Guide with information about how to upgrade a garage ceiling when a portion of the interior of the house is located directly above the attached garage by adding insulation and air sealing.
Guide describing how to apply an air control layer directly over existing wall sheathing and cover with two layers of insulating sheathing held in place by vertical furring strips.
This presentation will help you define insulated siding, understand R-value testing of insulated siding, describe proper installation of insulated siding, comply with energy codes and understand building energy performance program and software recognition.
Guide describing the installation of insulating sheathing above the roof deck on existing homes. This retrofit assembly is appropriate for homes with conditioned attics or where the retrofit is intended to create a conditioned attic.
Research study developing baseline engineering analysis to support the installation of thick layers of exterior insulation (2 in. to 8 in.) on existing masonry walls and wood framed walls.
The New York State Energy Research and Development Authority (NYSERDA) is interested in finding cost-effective solutions for deep energy retrofits (DERs) related to exterior wall insulation in a cold climate, with targets of 50% peak load reduction and 50% space conditioning energy savings.
Guide describing how to add spray foam insulation to the underside of the existing roof deck as part of the conversion of a vented attic to an unvented, insulated attic.
This report outlines research activities that are expected to facilitate the adoption of energy retrofits by remodeling contractors and roofing contractors using retrofit panels which applicable to many existing house designs in most climates and markets.
This page provides important information on how to protect yourself and your family if you suspect that you might have vermiculite insulation from Libby, Montana.

Document providing descriptions of the many insulation options available to homeowners, along with guidance on where, when, and how to install insulation throughout your house.
Guide describing how to upgrade walls that separate the garage from the house by providing a continuous air control layer on the garage side of the wall and adding rigid foam insulation.
Case study describing a 2013 DOE Building America Top Innovation for the installation of rigid foam insulation on the exterior of home roofs and walls as a thermal, air, and moisture barrier.
Document providing renovators and retrofit contractors an overview of considerations when including wall air sealing and insulation in an energy retrofit project.
The Guide addresses walls constructed with 2x4 wood frame studs, wood structural panel sheathing (WSP) as wall bracing and added backing for foam sheathing, a layer of rigid foam sheathing insulation up to 1.5 inches thick over the WSP, and a cladding system installed over the foam sheathing in low...
Research study describing an experimental and theoretical investigation of the energy and hygrothermal performance of retrofit foundation insulation systems in climate zones 6 and 7.
