Image
Wrong – Tree branches close to the house are prone to spreading crown fires to the house; the tree should be trimmed so that branches are at least 10 feet back from the red dashed line indicating the deck railing of the house.
Image
Wrong – Two combustion appliances are sharing a flue which could lead to backdrafting if one appliance is updated to a direct vent appliance and disconnected from shared chimney.
Image
Image
Image
Image
Wrong – When insulated sheathing is installed correctly, you should not see daylight. Nail holes were also left unplugged.
Image
Wrong – When insulating with spray foam, care should be taken to completely fill areas around piping and other penetrations to avoid leaving air gaps.
Image
Wrong – When more than one layer of insulation is installed, the seams should be staggered to discourage ground water from reaching the foundation wall.
Image
Wrong – Where possible, design walls and specify window sizes and placement to minimize the use of studs around windows; and seal all wood-to-wood seams to minimize air leakage through walls.
Image
Wrong – Whole house fan installed with holes in surrounding platform that need to be air sealed
Image
Image
Image
Wrong – Wind-driven rain and wildfire embers can enter an attic through the soffit vents.
Image
Image
Image
Wrong – Window not protected and failed due to windborne debris in hurricane force winds.
Image
Image
Wrong –Best practice solid air barrier material was not used behind the shower surround.
Image
Wrong –Excessive length and a vertical angle on this dryer duct reduced air flow allowing the dryer duct to become completely clogged with dryer lint
Image
Wrong –The gate that was attached to the garage at the corner ignited and led the fire to the home, causing the damage seen here.
Image
Wrong- A tie strap should not be used over the duct outer liner because it can compress the insulation. Tuck in the fibrous insulation and seal the outer liner to the connecting duct with mastic or foil tape (Steven Winter Associates 2013).
Image
Wrong- IR image shows lack of air sealing around door, at window, and at light switch is allowing in cold air.
Image
Image
Image
Wrong-The home was pulled off its masonry pier foundation during a coastal flood due to inadequate pier-to-beam connections.
Image
Wrong-These masonry pier foundations were twisted and displaced by coastal storm surges in Long Beach, Mississippi.
Image
Wrong: Blown insulation does not stick to raised duct chases
Image
Wrong: Closed-cell spray foam roof insulation was not thick enough to meet IRC levels so the foam surface is colder than the dew point of the interior air and condensation formed on surface of the foam
Image
Wrong: Drywall does not extend beyond chase wall framing and is unsealed in a hallway dropped ceiling chase
Image
Wrong: Drywall does not extend beyond the top plate of the interior walls. This installation has the potential for leakage at the sides where the ducts penetrate the side walls of the chase
Image
Image
Wrong: Ducts are held above the ceiling plane with strapping to provide a good angle into top-entry boots. Once the ceiling insulation is added, this duct will protrude from the ceiling insulation and will not be buried
Image
Wrong: Ducts are held from the rafters with strapping and a large beam prevents ducts from properly lying on the ceiling plane
Image
Wrong: Ducts are not laid across the lower truss cords or ceiling, but are hung from the rafters by straps. As a result, ductwork is not buried
Image
Wrong: Ductwork is not fully encapsulated with ccSPF insulation. The duct jacket is still fully visible at sections of the duct
Image
Wrong: Electrical components were installed near ground level and are likely to be flood damaged.
Image
Image
Wrong: Open wall cavities in the un-air-sealed return plenum connect the plenum to attic spaces
Image
Wrong: open wall cavity connected to this return air plenum is allowing cellulose attic insulation to be pulled into the furnace
Image
Wrong: Single sided ventilation without at least two windows, wing walls, and predictable wind directions is ineffective for generating wind-driven crossflow.
Image
Wrong: The door and filter were removed, allowing unfiltered air to enter the air handler leading to premature failure of the system due to dirt accumulation.
Image
Wrong: The fiber-cement siding has cracked due to over-driven nails located too close to the edge of the board; these cracks provide a pathway for bulk water entry and offer little resistance to high winds.
Image
Wrong: The homeowner mistakenly filled in the weep holes in this brick wall with spray foam, preventing drainage from behind the wall
Image
Wrong: The return plenum is not air sealed to separate it from the wall cavities and it should not be used for storage
Image
Wrong: The waterproofing around this hose bib was haphazardly detailed allowing water a pathway to wick behind the siding.
Image
Wrong: This air handling equipment is installed in the garage without isolating the equipment from the garage space
Image
Wrong: This is a poorly sealed chase where other trades have interfered with the integrity of the chase (electrical wires installed through the ceiling of the chase), as well as no air barrier on the chase sidewalls
Image
Wrong: This return air plenum is not lined and air sealed
Image
Wrong: This wall cavity is open to the attic allowing unconditioned, attic air to enter the HVAC system, bypassing the filter, and degrading system life and performance
