Attached garage

[PhantomEB]

My wife and I recently moved to the inlaws place to save up cash to buy our own place. We currently thinking we do like the town where they live and would like to stay in this town.

Only problem for me which really isnt a problem is 99% of the houses all have attached garages.

Who all here has such garage and what have you done to make sure the wife dont start yellin about noise or fumes coming from the garage?

I will be puttin the compressor either in an insulated shed outside or in an insulated cabinet in the farthest corner from the man door.

All walls/ceiling that adjoin to the house will be double walled (studded, insulated, drywalled then a second wall butted on top in similar fashion) to cut down on the noise.

Thinking makin such like an airlock around the door/stairs if such and second door, insulated, yadda yadda ya and with a very efficient bathroom exhaust fan that would be running the majority of the time I am in the garage.

I kinda likin the fact I can easily wander into the garage at my desire!

I have an attatched garage and prefer it that way . I will add the other half had full knowledge of my play activities when she moved in . I even have a shirt she got me that says the garage is mine you can have the rest of the house. I put my compressor in the corner furthest from the house and put a tight sweep on the door into the house. The only time fumes are a problem at all is in the winter when the garage is sealed up . We both smoke but not in the house so the garage is also the smoking room for the house . I will open the overhead door and side door if I am doing alot of welding just to keep the fumes moving . I also tend to sweep more to keep stuff from being tracked into the house and have three door mats infront of the door leading into the house.I also like the fact that its easier to keep an attatched garage warm than a detetched one .

Most of the noise from an air compressor comes from the intake. Putting the intake in a sound proof enclosure (vented of course) or outside will make a world of difference. Plumbing the intake thru some pipe with elbows will help cancel some of the impulse noise. Using a small engine muffler on the intake will help also.

That sound proofing link is something definitely new to me, now by alternating the studs like so, whats gonna happen when its insulated.... definitely something I need to research.

I have a laundry room between the house and garage with a small exhaust fan. I close both doors and run the fan when using anything that has a strong odor. Can't smell it in the house.

The insulation is part of the soundproofing. Check out the diagram and the rest of the site.

I have an exhaust fan rigged in my existing shop. I also have a big 36" attic fan turned on it's side to use during decent weather to move a lot of air for ventilation.

Duh brain fart.... now I totally understand how it works, with the studs not touching both sides of the wall, other than the end pieces, noise can not transfer thru the studs from the inside of the wall to the outside and vice versa.

Laundry room would be great to have right there at the doorway as it would also probably have a spot to wash up, MJB?

I am also thinking of rigging up an exhaust fan but have to get the garage first to see what I have to work with.

Obviously I aint the only gearhead whos gonna have to wrench and weld in an attached garage! ***** for the wife that the garage probably be one of the nicest but most used rooms of the whole house, other than the bedroom, wink, wink.

As for exausting welding fumes, a bathroom fan isn't enough. Go at a farm supplies store and get a vertically mounted wall fan like thoses used in henhouses or pigsty. They came in different sizes like 16", 24", 36" or even 48" in diameter and come rigged with flaps. They coud run 24 hours a day if you wish.

As an example, in my 20'x25' garage with 10' ceilling (5000 cubic feets), i had a 16" fan rated at 500 cfm, meaning that the air is completely renewed after 10 minutes of operation.

My exhaust fan is a squirrel cage salvaged from an old furnace. The belt drive types are easy to use since the fan speed can be lowered. A furnace fan is meant to operate in a slight vacuum. If you run them in free air the fan takes more power to run and the motor overheats. Dropping the motor pulley diameter usually works. An ammeter will help get the pulley sized properly. I usually use one of those variable pitch pulleys. A sheet metal or plywood ring can also be used as an airflow restriction on a squirrel cage fan to reduce motor load. The good thing about a direct drive fan is that the moving air cools the motor better. Since the fan is driven directly an air restriction is the only load reduction option. An ammeter should always be used to avoid any problems.

The farm supply axial fans are nice in that you can box in around the fan easily and make an insulated cover for them to hold heat better in the winter.

The furnace fan is a good way to go if you are just going to weld and not paint.
The problem with paint fumes is they can go **** when the go by a fan motor in the air stream.
To aviod this I have seen guys use the blower from an old cloths dryer to vent a paint booth.
These move a lot of air and the motor is out of the air stream because the designers are afraid of lint catching fire.
I have seen them run for hours with a 4 inch hole centered on the motor shaft to let the air into the squirrel cage fan.
They will have about 3 feet of 4 inch duct attached to get you started on the venting.

The only problem with attached garages as shops is the the fire codes are a lot stiffer.
It is concidered part of a home and inspected as such.
They worry about things that may happen while people are sleeping.
Not something they worry about in a detached building.

That is a good point about the paint fumes kbs2244. I normally just weld. I do occasionally use a rattle can to paint some small object.

When using solvents etc I usually have the door open with my attic fan outside blowing air into the garage. I can't use the attic fan when welding because it blows the shield away.

Having a heated garage may increase the opportunities to work inside during the cold months which could cause problems with flammable fumes. Heaters normally have to be 8' off the floor.

BTW- On a squirrel cage fan the air restriction goes on the intake side.
