Tools of the Trade
A hammer and a saw used to be the key tools for home contractors. Today, the best-in-breed also use high-tech equipment while performing a professional energy audit or verifying that construction has been done correctly.

Dry your clothes faster and prevent lint build up with the new LB1 Dryer Duct Booster. Clothes dryers are often installed in areas of homes where they cannot work effectively leading to long…"
David Meiland replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"Brad, the dryer box itself is simply a way to cleanly route the flex connector from the dryer to the rigid duct. Yes, it displaces insulation but it prevents the flex from becoming a coiled mess behind the dryer, and it lets the dryer sit against…"
Brad Cook replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"I have attached a photo of the original vent (brown vent hood low and to the right of the covered area), showing how the moist air goes up into the cathedral ceiling of that covered area between the house and garage. That moisture was instrumental…"
David Meiland replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"Brad, just curious, if the dryer is against an exterior wall, could you not install a Dryer Box directly behind the unit and eliminate the pipe run in the garage? Also, the vent caps from Seiho are the best ones I have found. They are around $50. I…"
Sean Lintow Sr replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"I think you explained it pretty well & I do love the quip "even BPI requires" - it is so nice when when they actually recognize codes...
A few quick points - your outside damper is plastic which is all I was suggesting. The only…"
Brad Cook replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"Maybe I am not communicating the nature of the problem in a very effective manner.
-To vent a clothes dryer (especially gas fired!) even BPI standards require metal ducting only, and not PVC.
-The ducting must be insulated after it leaves the…"
Sean Lintow Sr replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"wow 4 elbows - that adds 20 to the effective length which probably doesn't even include the flex line inside
as for the ice issue on the wall, the only thing I think of is do what they do in commercial & add a PVC 45 or 90 on the…"
Eric Kjelshus replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"older dryer could "push" more air than the new "energy star" dryer. I have put in line fans so to better damper in line so does not fill full of lint. But thats not what you are asking. I used 4" PVC and…"
ken Neuhauser replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"Brad,
If you've insulated the pipe, sloped to the outside, properly lapped the joints, left a drain hole or two at the bottom of the vent termination...then I think you're just up against physics. Physics wins every time.
The…"
Bill Smith replied to Brad Cook's discussion Venting a clothes dryer through an unheated garage"Brad,
If the pipe joints are dripping and you have a decent slope your joints may be reversed lapped. As for the ice on the siding, those vents direct the exhaust down along the siding. With a long run the exhaust may be cooling enough that it…"

We recently vented a gas clothes dryer through an attached and unheated garage, to an outside wall of the garage. We are located in Central Vermont. We used 30 ga. 4" galvanized duct and taped all joints (and elbows) with foil tape. we foamed around the opening where the duct left the house. The duct has 4 elbows and runs about 17 ft. total. Most dryers can handle this effective length. We used a standard 4" plastic vent hood on the wall of the garage. We wrapped the duct in 3 1/2" unfaced…See More
