They have low pressure loss (forget the value but it is a lot less than baffles). Fantech is the source. - Any benefit re:sound to using two smaller liners instead of one big one and only using one at a time when using only one side of stove? Or is this magnifying the cost for no good reason other than sound? (Because I'm assuming I'd then have two runs up and out and two things on the roof because they wouldn't combine to avoid a turn and to ensure proper function? If only one side were run at a time, then MUA costs could be lower, but where code requires MUA, I am willing to bet a donut that the AHJ will demand an MUA system that can handle both at once. In theory, the sound reduction will be only 3 dB less. Also, when using the central burners, you will still need both systems for capture and containment. Well, I guess three things on the roof then with the MUA. While commercial systems mostly use roof MUA entry, and I use roof MUA entry, the options for residences are wide open and may include side of house entry, or entry into a basement that has an air path access to the kitchen.

This is how my husband suggests putting up the drywall around a rectangular furnace duct. #1 Screw in a strip of drywall backer board into the ceiling joists, in front of the duct . #2 Another drywall backer board is attached to the wall, just below flush with the duct. #3 Measure and cut a drywall strip for the long vertical side of the duct worK. #4 Before you do anything else, attach another drywall Backer strip along one side of the drywall strip. This will become the bottom edge. #5 Screw on the upper edge of this drywall strip that you made to the backer strip that was attached to the ceiling joists (#1). #6 Measure and cut a drywall strip for the bottom (underside) of the bulkhead/ duct. #7 Screw this into place, into the backer board strips. #8 Attach your corner bead.

I'm not the right resource to ask for specific plants or even a landscape design - but there are some awesome posters in the landscape forum that know these things. I know when a particular landscape doesn't work well because I'm a Realtor and curb appeal is critical in my business. However, I'm in South Fl - so I have no idea of the plants that work in your area and I don't want to mislead you at all. I do know if you start to put a tree in to cover up something on the second floor a natural response by normal people is to follow the tree upwards with your eyes and you have then actually made the vent more visible rather than less visble. That's why I said to change/beef up your landscaping. If I were there I would be putting a tree off of your far right corner and adding in colorful swaths of flowers in the planting beds.

did you post the photo of the radiator cover/idea that you had? it did not post. yes, I agree with a toddler, that would not be a good idea at all. You could enclose it in a cabinet with flat front - like dry walled in. then put a photo/artwork on the flat part, if that makes sense. the art would be attached to the wall just like any other frame. if you did put a cabinet cover there like the white one above, you could paint the same color as the wall - it might not stand out as much? if you removed it, could you put a window there instead of trying to match the brick - just first thought that came to my mind. maybe it could be a cool shape window and not just a rectangle? not sure how much that would cost. or I wonder if you could cut a window to match the one next to it. again I have no idea how much it costs to add in a window. it might be too close to the corner for that though?
