How to Ventilate a Detached Garage
Overtime, your garage will become a pent-up warehouse full of car fumes and other chemicals such as paint and insecticides. The last thing you want are these toxic fumes lingering in your garage which is not ventilated well, especially in the summer.
To make your garage safer to use as a space or storage, we’ve come up with a few tips on how to help.
There is no better way to draw out fumes than to install windows. Having the windows across from each other on opposite walls provide the best ventilation. Open both windows to bring in fresh air and have the bad air circulate out.
This will create a free flowing current that will be sure to ventilate the garage, carrying out the bad and in with the new. If you have an attached garage however, you cannot do this as one wall would be adjoined to the home. Be careful leaving windows open at night, as that can invite thieves to steal your precious tools.
Add a Window Fan
If you already have a fan and don’t want to install another one, an inexpensive fan can draw out the air from the garage. Having a box-style floor fan Infront of a window can also work.
Have the garage door open and allow the fan to pull in fresh air while the dewy air is pushed out. The fan can also be great for small spaces such as gaps around a garage door, even if it’s closed.
Install Roof Turbine Vents
Round and bulb-like in it’s natural form, roof turbines can a good investment. They are at the top of your roof, spinning and pulling the air up from the garage.
There are installation costs to go with it, but since it doesn’t require electricity, it can be cost-effective in the long run.
Similar to the air vents in your home, static vents are installed in the walls of your garage. Have the slats angled when installed so rain water will fall away from the vent opening rather than allowing the rain to enter in.
These vents are best installed when placed high on a wall and the other vent low on the opposite wall. An air current is produced that pulls fresh air around the garage while allowing the bad air to be pushed through the higher vent.
It’s similar to the two opened windows, but safer as you won’t have to leave these open at night.
An exhaust fan can be helpful for pulling out toxic fumes, depending on the size of your garage. Exhaust fans typically found in the bathroom can work in small areas, especially near the washing machine that adds moisture to the air.
Attic fans are powerful as well, which are installed in the ceiling and forces air up from the garage out to a vent in the roof. A kitchen range hood, while less common, can be effective.
A device that vents to the outside is more ideal, even installing one where you normally work. Range hoods can be noisy however, but cost-effective and efficient at removing toxic air fumes.
