Image
A 1- and ½-story home with a room located in the attic and the thermal boundary located at either a) the walls and ceiling of the attic room with small vented attic spaces or b) the roof line for an unvented attic
Image
A low-sloped shed roof with the thermal boundary located at either a) the flat ceiling with a vented attic or b) the roof line for an unvented attic
Image
Image
Advanced framing details include corners that are constructed with fewer studs or studs aligned so that insulation can be installed in the corner.
Image
Advanced framing details include framing aligned to allow for insulation at interior-exterior wall intersections.
Image
Image
Image
Design the roof with raised heel trusses to allow full insulation over the top plates of the exterior walls.
Image
For slabs on grade in CZ 4 and higher, 100% of slab edge insulated to ≥ R-5 at the depth specified by the 2009 IECC and aligned with thermal boundary of the walls
Image
In cathedral ceilings, parallel chord trusses allow thicker insulation levels over the exterior wall top plates.
Image
In cold climates, install slab edge insulation when pouring slab on grade foundations.
Image
Infrared thermography during depressurization testing reveals air leakage at corner of spray foam-insulated room where wood-to-wood seams in framing were not air sealed
Image
Install continuous rigid foam insulation or insulated siding to help reduce thermal bridging through wood- or metal-framed exterior walls.
Image
Install insulation under platforms constructed in the attic for storage or equipment.
Image
Image
Image
Ladder blocking where exterior walls intersect interior walls provides more space for insulation and reduces thermal bridging.
Image
Lay out the rigid foam sheathing joints so they do not align with the window and door edges
Image
Limited attic access can make inspections for missing air barriers and insulation challenging
Image
Limited attic access may make it necessary to use a bore scope when inspecting for missing air barriers and insulation in existing buildings.
Image
Image
Image
Image
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
Image
Image
Image
Right - Continuous wall sheathing and blocking has been installed to brace the raised heel trusses.
Image
Right – All insulated sheathing boards are installed according to the manufacturer’s recommended fastening schedule and taping specifications
Image
Image
Image
Image
Right – Full length 2x6 nailer has been installed to allow space for insulation at wall intersection
Image
Image
Right – Insulation installed to correct depth and will be aligned with air barrier
Image
Image
Image
Image
Image
Right – Structural insulated sheathing can provide racking strength (lateral load resistance), and serve as an air barrier and thermal barrier if installed according to manufacturer’s specifications with taped, sealed seams
Image
Image
Right – This attic knee wall and the floor joist cavity openings beneath it are being sealed and insulated with spray foam.
Image
Image
Image
Image
Image
Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Image
Rigid foam insulated sheathing placed exterior to house wrap, interior to house wrap, or take the place of the house wrap
Image
Image
Standard roof trusses are narrow at the eaves, preventing full insulation coverage over the top plate of the exterior walls
Image
The attic kneewall and the open floor cavities under kneewall are both sealed and insulated in one step with spray foam insulation
Image
The thermal boundary for a gable roof can be located at either a) the flat ceiling with a vented attic or b) the roof line for an unvented attic
Image
Two layers of XPS are installed with staggered seams over a liquid-applied membrane on the structural sheathing
Image
Use flashing tape to seal around any pipes or vents that penetrate through the foam
Image
Image
Image
Wrong - Batt insulation does not provide complete coverage across the attic floor so ceiling joists are exposed resulting in thermal bridging.
Image
Wrong – A visible gap in the insulated sheathing introduces unwanted outside air, creating a thermal bypass and encouraging convective air flow
Image
Wrong – Conventional T-post detail is extremely difficult to insulate and usually doesn't happen
Image
Wrong – Either this tape was not pressed down firmly or the surface was wet or dirty so the tape is not sticking properly even during construction.
Image
Image
Image
Image
Image
Wrong – If the insulated sheathing will serve as an air barrier and drainage plane, any cuts and seams must be taped or sealed.
Image
Image
Image
Image
Image
Image
Wrong – The framing and wind baffle installation will not allow for required insulation depth.
Image
Image
Wrong – When insulated sheathing is installed correctly, you should not see daylight. Nail holes were also left unplugged.
