They make foundation/crawl space vent with a bimetal closing mechanism that opens at a high temp and closes at a lower temp does anyone make a vent that will auto close at a higher temp ? I would like put vents in garage door and vents in garage ceiling, considering safety concerns I would want the ceiling vent to close at a higher temp rather than feed a potential fire. At this point I haven't found anyone making something like this ?? TIA

If you put a vent in the ceiling, it must be a certified fire damper that will automatically close to prevent fire and smoke from spreading into the attic. Otherwise, you would be violating the building code.

That's why I am looking for something that will close with heat , always try to KIS , keep it simple, no powered fan ,vents at the bottom of garage door , vents in ceiling, chimney affect keep temp at outside air temp, best that can be done until the air is turned on

This may work in the ceiling, but you may need to cover the underside with a regular ceiling grille. You would get more air movement with a fan. But, even with a fan, you may not get enough ventilation to meet your needs. I have a neighbor who installed garage door vents and an attic fan, but he was very disappointed with the air flow.

You don't need a fire damper in the garage door. You can just cut a hole in the garage door and install a grille.

SolarGuys has what you want. I've had one for 10 years and it works great.
Call them.

• The most efficient and best possible application is a low-profile Kennedy solar vent. Economical, non intrusive, long-life, and we have installed them for the last 3-4 years.

The older versions were not as equitable and efficient as these newer (more durable) models.

I live in Virginia Trace and we have put many in our properties. Best investment for long hot summers and hot attic air removal.

I think the OP is looking for a ceiling vent to move air through the garage and into the attic, not a roof vent.

Happens if the bearings fail.

In Florida, you pull hot air off the driveway into the garage so venting is not much help anyway.

I agree, but some fans are noisy anyway. A neighbor installed an attic fan and 2 vents at the bottom of his garage door. He used it for about a week or so and never turned it on again. The fan was noisy, but the biggest problem is that you don't get much air flow through the garage door vents.

When was this required? I have original vent in my garage close to furnace. It has no automatic door or door at all just large tube duct sticking up above the attic insulation.

It's complicated. Here is a home inspection article that addresses duct openings in the garage ceiling, and refers to the 2006 International Residential Code. Basically, the garage ceiling should be constructed to not allow a fire in the garage to spread into the attic, which could allow it to spread into the living area.

Thightwadmo asked: "When was this required?"

You need to think in terms of being burned alive, not a 'requirement'. If you have a garage fire* the fire will be moved to the attic by the fan which will burn down to you in your bedroom**. The garage as built, is designed to prevent this.

*The garage is your #1 source of unattended fire in a home. It is second only to the kitchen. Kitchen fires are more likely to occur when you are in or near the kitchen.

**Over seventy years ago building codes were changed to prevent 'burn downs' which were quite common in balloon framed homes.
