Standing seam roofs can be a pain to flash penetrations sometimes because, invariably, the penetration usually lands on one of the seams (Murphy's Law?). My solution would be to have a local sheetmetal shop custom build a flashing for you. It may cost you a little bit, but not near as much as the damage you might incur down the road with a cobbled together leaky flashing. If there is no sheetmetal shop nearby, you might contact the original supplier of the roofing for their recommendation or a lumber yard who sells the roofing product line. If you do get a flashing and are installing it yourself, be sure you get clear instructions on how to cut into the roofing, how to set the flashing and how to fasten and weatherize it properly. Have all the right tools and safety gear for working on a roof. Another way to seal a penatration through a metal roof is with a product called a deck tite pipe flashing system. This is a EPDM rubber boot that fits over and/or arount the penetration. It is installed with sealant and screws through the roofing and has semi rigid metal collar that can conform the the ribs of any roofing. I purchase such products from a company called Dynamic Fastener.
Kitchen exhaust hoods may be purchased locally through most appliance stores and home centers. They may also be purchased online from Lowe's, Home Depot, Sears, and Amazon.
Kitchen exhaust fans may be purchased through stores such as Canadian Tire, Home Depot, Lowe's and Rona. Each store will have some similar brands but may have different models. One may also calculate which offers the best loyalty rewards to maximize their value.
This is not a good idea, as chimney fumes could come the other way. It would be illegal under most municipal building codes.
If you are looking to update your kitchen, you can install a new Blanco sink. They are available online through companies such as Ferguson and Faucet Direct. You can also shop in person at home improvement stores such as Home Depot.
through the kitchen
They don't install the tiles through their own employees directly. However, they have arrangements with contractors so in theory, these contractors are vetted and competent and it's better than just picking someone out of the phonebook.
Exhaust gasses are escaping through a hole or rotted section of exhaust system
as hot as the exhaust manifold there are exhaust gases passing through it
That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.
The exhaust is expelled directly from the engine using straight pipes through the stern of the boat, above the water line. Normally high speed boats are equipped with these types if exhaust system.
You need to study the circulation pattern of your kitchen to make that choice. Do you need or want people to circulate through the kitchen. A peninsula will limit the circulation through the kitchen. There is something nice about not having traffic in a kitchen when working. If your kitchen is big enough it may accommodate both.
A ductless exhaust provides a short channel for the airflow to pass through, while a ducted exhaust provides a pathway to move the air far away.
