What is flashing in interior design?
Flashing is a type of impervious material used to prevent water from entering a structure or as part of a weather-resistant barrier system. It is used in modern buildings to reduce water penetration at various objects, such as chimneys, vent pipes, walls, windows, and door openings, making buildings more durable and reducing indoor mold issues. Metal flashing materials include lead, aluminum, copper, stainless steel, zinc alloy, and others. The term “flash” and “flashing” may have its origins in the Middle English verb “flasshen”, meaning “to sprinkle, splash”.
Counter-flashing, or cover flashing, is when two parallel pieces of flashing are used together, such as on a chimney. The term “apron” is still used for the piece of flashing below a chimney. Up-hill side of a chimney may have a cricket with cricket flashing, or back flashing or back pan flashing on narrow chimneys without a cricket.
What is the metal piece under the door?
A door sill is a piece of timber or metal with a seal attached underneath it, typically found on external doors. It prevents dirt and water from entering the door, often referred to as a threshold or weathering bar. These sills are particularly beneficial in areas with sloped paths or susceptible to water pooling. They also help prevent draughts, but it is recommended to use a draught excluder internally to fully counteract this issue. Overall, door sills are a valuable investment for maintaining a clean and dry environment.

What is the purpose of wall flashing?
Wall flashings are water-resistant membranes, metals, or plastics installed inside walls during construction to collect and direct water from the exterior through cracks. They must withstand the abuse of construction and should be a crucial part of building design. Poor material or sealant services can damage the building’s structural integrity in the long run. Wall flashings maintain healthy and structurally sound buildings by protecting integral parts of the structure, especially around pipes.
Water can enter the building through various mechanisms, including hydrostatic pressure, capillary action, wind/air currents, surface tension, and natural gravity. Therefore, it is essential to apply flashing to any pipe that enters or exits the wall.
What is the metal bar at the bottom of the door?
Weather bars are essential accessories for external doors, providing protection against adverse weather conditions. They should be attached to the bottom edge of a door and work by deflecting wind and rain. They are also available in a weatherstrip, used to seal a door when closed. Our range of weather boards is perfect for various doors, including LPD doors, and can be painted or treated to suit your needs.

What is the purpose of flashing on a house?
Roof flashing is a thin material, typically galvanized steel, used by professional roofers to direct water away from critical areas of the roof, such as vents, chimneys, and skylights. It is installed to surround these features, ensuring water runs down the side and directs to the shingles instead of entering the roof deck. Damaged or improperly installed roof flashing, particularly around chimneys, roof crickets, or dormers, is a common cause of roof leaks, wood rot, and deck collapse. To install or repair roof flashing, follow these steps:
- Understand the purpose of roof flashing.
- Install the flashing correctly.
- Follow the installation instructions carefully.
- If necessary, repair the flashing.
What is the flashing at the bottom of the wall?
The wall system starts with base flashing at the bottom of the wall, collecting water that drains down the wall and kicks it out at the base. Metal or PVC flashing should have a drip edge hanging below the sill plate, with the bottom edge at least 8 inches above grade. Install flashing at the bottom of all exterior walls and integrate it with other wall water management details to direct water down and out.
Install flashing under the bottom edge of the house wrap or weather-resistant barrier shingle fashion to direct water out of the wall. Install self-adhesive flashing behind the weep screed, a perforated metal strip at the base of the exterior walls, and water-resistant barrier to overlap the top edge.

📹 How to Flash a Window Sill | ZIP System™ stretch tape
A quick 1-minute how-to video on how to flash a sill pan using the unique ZIP System™ stretch tape as seen on …
I’m trying to learn how to do this so I have a couple questions if you don’t mind answering them. You first put the flashing tape on the sill and up the sides, then you followed with flex tape on those bottom corners. Why not put the flex tape in those corners then put the tape over that on the sill/sides? Seems like that would be the better way to shed water if it got in and ran down the sides. My second question is why not tape all the way up the sides and the top of the opening? Wouldn’t that be a good idea to prevent any air that gets behind the window from making its way into the house? I know that some people don’t put sealant on the bottom flange of the window so that any water that gets in can escape (not sure if you did that here or not) but if you did and the window has a great seal to the sheathing then I guess I can see why you wouldn’t need to run tape all the way up the sides and across the top.
I don’t know, I like to do my windows like you do a skylight. Not just pee and stick on the framing waiting for caulking to fail. Then water gets led inside (but at least the framing is protected?) leaving the insulation and interior sheathing waiting for doom. All tyvek, blueskin, zip tape, tuck tape etc etc people wrap the framing and not seal the windows….
Great article. As a new soon to be home owner(new build). I want to know about some standards. I see you used the stretch to overlay the corners (which were cut with zip tape), to prevent water intrusion. 1)Is it better or safer to just use the stretch period instead of overlaying, as this would provide better integrity? 2)Also, I see you did not put zip tape around the perimeter of frame before you installed the window, is this minimum standard ? Is it overkill if you did or just a peace of mind thing??? 3)Also, is there a minumum overlap of tape on bottom of sill required.??
Great article! Quick question. You mentioned in one of your reply’s you seal the window along the bottom in the inside as to direct water out the front where nail flange is. What product do you seal it with? And is the the same product you used along the top and side nail flange prior to installing? Appreciate all the insight and time you guys spend on these articles! Cheers.
Remember the Zip system counts Entirely on the tape been installed properly and in Dry weather conditions, clean Sheathing . I put the odds on that happening at about 20% in todays market. Stick with your Tyveck if you want a good vapor barrier and to increase your odds on having a good job. I put House wrap odds at about 78% to get installed properly .
My life has completely changed since I have found this tape. My contractor gave me a roll, and I used it to seal gaps on my window AC units that I install in my home each summer season. Wow! The efficiency I have gained is incredible. Secondly, this tape has been my muse fir all sorts of mcguyvering needs around the house, duct tape is no longer my go-to. The fact that this tape is so tacky, can stretch around complex shapes, and yet remains 💪 strong is simply amazing.
