Image
Image
Right – The ties are bent at a 90 degree angle at the nail head and embedded into the mortar joint at least 1.5 inches.
Image
Image
Right - Manometers are placed away from the indoor side of the fan during blower door testing
Image
Right - These homes have hurricane shutters to protect against high winds and to provide solar control.
Image
Image
Image
Right – Appropriate use of framing members to support double windows and additional cripples for drywall purposes
Image
Right – Backer-rod is a foam product available in various diameters that can be used to air-seal openings around doors and windows.
Image
Image
Image
Right – The blower door is installed snugly and securely to the door frame during testing
Image
Right – The blower door pressure reference hose is placed well away from the outdoor side of the fan
Image
Right – The flashing is properly installed to create a complete drainage system with continuous rigid insulation sheathing/siding
Image
Right – The rough opening around the window has been filled with low-expansion foam to air seal.
Image
Right – The rough opening around window has been filled with backer-rod to air seal.
Image
Right – There is flashing installed along the top of the window and the water-resistant barrier is layered over to create a complete drainage system
Image
Right – This exterior door is installed to swing out and has storm protection shutters.
Image
Right – This metal panel window shutter is installed in a track permanently mounted above and below the window frame and is secured with wing nuts to studs mounted on the track.
Image
Right – Transfer grilles, Jump ducts, and wall grilles provide passive returns for air returning from bedrooms to the central HVAC system
Image
Image
Image
Image
Image
Right – Weatherstripping has been installed and remains in contact when the door is closed.
Image

Image
The grille in the photo on the left brings air into a return air plenum under an air handler platform. As shown in the infrared image on the right, the plenum is not air sealed so hot attic air is being pulled into the air handler closet.
Image
The unprotected glazing in this door was broken by roof tiles dislodged by wind.
Image
This hot climate zone home uses high quality batt insulation to insulate truss-joist headers.
Image
Threshold Sweep Flashing protects the door and helps to keep out wind-driven rain.

Image
Image
Wrong - During high winds air entered the home elsewhere and pushed out the door which was inadequately anchored to the wall.
Image

Image
Image
Wrong - This IR image shows a lack of air-sealing around the door, window, and light switch that is allowing in cold air.

Wrong - Vinyl siding in incorrectly installed under not over door trim and door trim channel pieces are missing.
Image
Image
Wrong – Fibrous insulation is not an air barrier and cannot be used to air-seal openings.
Image
Wrong – The blower door is installed improperly with a gap at the corner and along the side of the frame that will allow air leakage and could allow the frame apparatus to become dislodged during testing
Image
Wrong – The blower door pressure reference hose (blue) ends too close to the outdoors side of the fan. Air moving across the end of the hose will affect the pressure reading
Image
Wrong – The corners are not properly flashed, leaving a vulnerable area in the drainage system
Image
Image
Image
Image
Wrong – There is visible light around the door because no weather stripping has been installed.
