Image
Expanded polystyrene insulation is installed with joints taped and lath attached in preparation for the application of stucco
Image
Image
Install continuous rigid foam insulation or insulated siding to help reduce thermal bridging through wood- or metal-framed exterior walls.
Image
Image
Lay out the rigid foam sheathing joints so they do not align with the window and door edges
Image
Image
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
Image
Right – All insulated sheathing boards are installed according to the manufacturer’s recommended fastening schedule and taping specifications
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
Right: All joints in the rigid foam are taped to keep stucco out of joints for even drying. Mesh tape (shown here) is used with expanded polystyrene (EPS); acrylic sheathing tape or self-adhered membrane is used with XPS
Image
Rigid foam insulated sheathing placed exterior to house wrap, interior to house wrap, or take the place of the house wrap
Image
Stucco is installed over rigid insulation, which is installed over a drainage plane consisting of a drainage gap and building wrap layer over the sheathing
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 - Lack of a weather-resistant barrier allowed water to get behind the siding and rot the framing in this corner rim joist area.
Image
Image
Wrong – A visible gap in the insulated sheathing introduces unwanted outside air, creating a thermal bypass and encouraging convective air flow
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
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
Wrong – When insulated sheathing is installed correctly, you should not see daylight. Nail holes were also left unplugged.
