Dearest TIM: The garage fastened to my townhome gets the full afternoon sun. The temperature in the garage has reached 110 degrees at times this summer.

In that location's some attic space to a higher place the front half of the garage and two bedrooms over the rear half of the garage both of which get very warm during the summer.

Would an insulated garage door help keep the garage libation, or is in that location a way to vent the garage to remove some of the hot air? I have a roll-downwardly screen, but in the summer it does non seem to offering much relief from the heat. Jan McM., Largo FL

DEAR January: No wonder your garage is an oven.

Is West Facing Garage the Worst?

You garage west-facing orientation couldn't be worse. As the 24-hour interval progresses and temperatures climb, they frequently peak betwixt 4 and 5 p.m. This is exactly when the direct rays of the sun are cooking everything they shine upon including your garage and everything within it.

Practice Cars Add Oestrus to a Garage?

Yes, cars that have been out on the route and then park in a garage add considerable heat to the space.

All of the machine's mechanical parts can be very hot afterward it has been driven for but x or 15 minutes in the summer months.

Some of the parts, similar the disc-restriction rotors, can hands be in backlog of 250 F. The car will radiate estrus into the garage for hours after it'southward parked.

Does the Concrete Floor Store Heat?

If the sun beats on your concrete floor, it acts similar a massive heat sink. I've tried to walk across concrete in the middle of summertime with bare feet and scorched the bottoms of my feet.

You can imagine how much oestrus the physical collects from the sunday and then releases it later.

The direct sunlight is cooking the physical floor raising its temperature. Await at the infrared photo only below to run across how hot the concrete is! Copyright 2018 Tim Carter

The concrete is already 126+ F and information technology's just subsequently noon. Afterwards a few more hours, information technology's going to be getting up or over 140 F! Copyright 2018 Tim Carter

Wait at the deviation! The concrete under the motorcar in the shade is only 87.ix F. You can run into why you desire to go along the physical shaded if you lot want your garage cooler. Copyright 2018 Tim Carter

Does an Insulated Door Cool the Garage?

An insulated garage door tin trap oestrus inside a garage. Insulation is designed to slow the transfer of rut.

If you were to install an insulated garage door and close it, you would trap this estrus inside the garage where you do non desire it. An insulated garage door may be a great thought for other times of year, it merely becomes problematic in the summer months.

Does An Insulated Door Assistance in the Winter?

Insulated doors are fantabulous if you're in a common cold climate and wanting to preserve auto estrus in the winter months. If you live in parts of the deep southern The states, Florida or the southwest where it rarely gets cold, I don't know if I'd go one if I wanted a cooler garage.

Do All the Contents of the Garage Radiate Oestrus?

Just every bit the metal parts in your automobile absorb and radiate heat, so do all of the objects in the garage. Think of how a dying campfire'due south embers and any rocks that surround information technology radiates rut for hours after the flames have stopped flickering.

How Long Will the Rut Final?

This low-level infrared rut can be felt inside a garage fifty-fifty early the adjacent mean solar day. I know, equally my own garage gets very hot in the summertime months.

It'southward very common for my interior-garage temperature to be 10 or 15 F warmer than the outside air temperature when I become into the garage in the morning. The ceiling and walls of my garage are well insulated.

Will the Garage Heat Rise to the Attic?

The heat from the garage will admittedly contribute to high temperatures in the attic space higher up likewise as the finished rooms. Hopefully, the ceiling cavity between the garage and the finished spaces was insulted. If non, you may want to consider adding blown-in insulation.

Heat moves from hot places to cooler places. That'south the basic law of thermodynamics.

This means if your garage is 110 F and side by side rooms are 85 F, then the nearby rooms are going to be absorbing the heat. You can't stop this transfer.

What is the Best Garage Ventilation?

The best garage ventilation is lots of moving air. You lot want to bring in cooler air from outdoors into the garage.

To cool your garage as efficiently as possible, you probably will demand to install 1 or ii powerful sidewall ventilation fans. There are any number of fans designed to pull air through the garage and frazzle it dorsum outdoors.

Here'southward a sidewall garage fan. It's meant to ventilate out the side of the garage. These come in different diameters. The bigger the blade, the more air it will motion. CLICK THE Paradigm NOW TO BUY Ane.

How Cool Will the Garage Get?

The fans will not be able to drop the temperature lower than the outdoor air temperature. It may experience libation to y'all as y'all stand in the path of the blowing air, simply that's caused by the perspiration evaporating from your skin.

This means if it is 90F outdoors at 5 or 6 p.m., it will probably be in the upper 90'southward F within the garage.

Important TIP: The fans must have plenty of incoming air to feed their voracious appetites. You'll probably have to keep the garage door upwards off the flooring nearly 4 inches to ensure plenty of air from outdoors is flowing through the garage.

The fans volition do the best task of cooling if they're located loftier on the wall directly opposite the garage door.

The fans will pull the air across the garage if you take this orientation.

Will the Garage Contents Get Cool?

The air stream will seem very cool to you if y'all stand in information technology. But don't think the objects in the garage experience equally cool equally you do.

You feel absurd because the evaporating perspiration on your skin is speedily extracting heat from your torso.

The inanimate objects in your garage do not sweat, so they volition have a while to cool downwardly.

Should I Install a Timer Or Thermostat Switch?

Consider putting the fans on a timer that allows them to run for several hours or use a thermostat to control when they get off. You can buy thermostats that will turn the fans on and off at predetermined settings.

This is a time-tested timer switch. You rotate the dial and it operates for how much fourth dimension you choose. CLICK THE IMAGE Now TO Buy IT.

How Big Should the Fans Be?

To practise any appreciable cooling y'all're looking for ventilation fans that move thousands of cubic feet of air per minute. Always use price as a guideline.

Fans with well-counterbalanced blades, high-quality motors and excellent exterior weatherproof self-endmost louvers will always toll more. I urge y'all to buy as much fan as you can possibly afford.

Should the Fans Be on a Divide Circuit?

Aye, exist sure the electrical wiring that'due south installed to brand the fans work is a separate circuit and washed according to all codes.

There'due south a practiced chance you'll take to install a new circuit or two if you buy big fans. They can depict a significant amount of electricity, and tin can overload existing circuits if yous are not careful.

Author's Comments:

The following are comments from several emails between Norm Sippel and Tim Carter, founder of AsktheBuilder.com.

Dear Tim,

"I faced a similar problem when I moved here three years ago. My hobby is racing vintage sports cars. I need to work on the cars year-circular. Early on in March of our first year here, I went to the garage (which faces eastward) at 10 a.m. I measured the steel door temperature with a pyrometer at 114 degrees. Information technology was a radiator. No way I could work in those conditions in March, much less in August.

My solution - I insulated the garage doors (a double & a single) with 2" cream panels from a large box home store. I glued them to the panels between the ribs & under the beams. The few metal pieces that were still exposed were still hot, just closer to 100 degrees.

The ambient temperature in the garage dropped into the low 90s. I added blown-in insulation after that. Mid-summertime the ambience temperature in the garage was down into the high 80s. Running two 5" air conditioning inlets into the ceiling that I can open up if necessary dropped the temp even further. I keep them closed when I am non working in the garage & there is no return duct for rubber reasons. This dropped the temp in August to the depression to mid-80's. That's a tolerable temperature.

You are correct that bringing a hot car into an insulated garage volition merely keep it hot in at that place. The brake rotors you note as a major heat source cool a lot faster than the radiator, frazzle & engine do. But if January leaves the car out until after night when it cools downwardly (to the high 70s/low 80s here) before bringing information technology in, it will be a much-improved situation. And, the insulated garage door will practice its chore in the afternoon sunday. That alone should lower the in-garage temperature about 15 degrees in the circumstances described."

(Tim Carter comment: I'g all for insulated garage doors, you lot but have to realize they block the heat transfer in both directions. The insulation holds in the rut overnight.)

"That'southward true. But, managing the interior temp is a lot easier when yous don't take and so many square anxiety of metal radiating heat to the interior.

Before I moved south, people said to avert w-facing back-yards. I had hoped to find something where I could sentry the sunset. Well, that didn't happen. I'm a mile inland from the Gulf. And, the dorsum of my house with big sliders faces north. BUT, I have even bigger sliders that do face west. So, we have to deal with that. The all-time solution has been Queen Palm trees. In three years, they are alpine enough that they shade the sliders by 4 p.m. in mid-summer.
