Over the last couple of weeks, I installed the supply ducts that take air from the air handler, ERV and dehumidifier, and distribute it around to different vents through the ceiling.<\/p>\n\n\n\n

\"\"<\/a>
These ports were each built using two inline-duct connectors joined together.<\/figcaption><\/figure>\n\n\n\n

I first cut holes and then foamed in three main lines for the air handler and the dehumidifier.<\/p>\n\n\n\n

\"\"<\/a>
Getting two 10 in. and one 14 in. duct in this tight space required staggering them a bit.<\/figcaption><\/figure>\n\n\n\n

Later I will use the other side of these ports to connect up the equipment.<\/p>\n\n\n\n

\"\"<\/a>
The ERV line is a 5 in. duct, tucked behind the ERV, which will be harder to install but at least out of the way.<\/figcaption><\/figure>\n\n\n\n

I made one for the ERV as well, which supplies fresh air.<\/p>\n\n\n\n

\"\"<\/a>
I used special nylon webbing to hold the duct up into the cavity.<\/figcaption><\/figure>\n\n\n\n

I had to modify one of the rafter blocks to get the duct through, but otherwise the ERV line ran nicely in the rafter bay.<\/p>\n\n\n\n

\"\"<\/a>
These corner supports ensure the duct doesn’t kink when it’s tugged during installation or when it settles later on.<\/figcaption><\/figure>\n\n\n\n

I made a wide sweeping corner to improve airflow.<\/p>\n\n\n\n

\"\"<\/a>
The duct boots are oversized to reduce noise and have gaskets to reduce leaking.<\/figcaption><\/figure>\n\n\n\n

I also put all ten of the duct boots in place, in most cases having to remove some of the closed-cell foam from the ceiling to get them to fit.<\/p>\n\n\n\n

\"\"<\/a>
These metal parts ended up adding up to a much lager expense than I expected.<\/figcaption><\/figure>\n\n\n\n

The entire system uses a number of wyes, reducers and elbows, all of which are done with rigid connectors.<\/p>\n\n\n\n

\"\"<\/a>
The ducting is a special type of flex-duct that has a special sound-deadening inner lining.<\/figcaption><\/figure>\n\n\n\n

The smaller air-handler line runs to just above where desk will be.<\/p>\n\n\n\n

\"\"<\/a>
Multi-way wyes like this are often made from a square box, but this design should improve airflow.<\/figcaption><\/figure>\n\n\n\n

The larger air-handler line splits up into four smaller lines in the live room ceiling.<\/p>\n\n\n\n

\"\"<\/a>
It started to get very crowded up there, but ultimately careful planning paid off.<\/figcaption><\/figure>\n\n\n\n

The ERV and dehumidifier lines also runs to the live room ceiling, where each splits in two.<\/p>\n\n\n\n

\"\"<\/a>
It’s a shame you won’t be able to see this after the drywall goes on.<\/figcaption><\/figure>\n\n\n\n

The final result is three lines leading to ten vents, distributing hot, cold, dry and fresh air where it needs to go.<\/p>\n","protected":false},"excerpt":{"rendered":"
