Even though everyone understands that heat rises, you might be wondering why one of your upstairs rooms is so difficult to keep warm. If the room is over the garage, there are various reasons why it is frequently the coldest room in the home. There is no heat to rise in to the room above because many garages are not heated.

If the garage isn’t sufficiently insulated, heat can escape through gaps and cracks, exacerbating the situation. If you’re having trouble figuring out how to solve this issue, stay reading for our advice on keeping the space over a garage warm and comfy.

What Are The Reasons For Cold Space Above Garage?

The level above a garage is rarely insulated. In addition, inadequate thermal treatment and air leakage can wreak havoc on comfort in homes with attic knee walls. Both of these issues are common in bedrooms above garages.

It’s a double whammy when it comes to temperature regulation. To compensate for the lack of insulation and air sealing, most HVAC contractors fail to install adequate ductwork in these locations. A bedroom above the garage may have the same airflow as other bedrooms, even though it requires significantly more ventilation to be comfortable.

If your garage is not adequately insulated, you will lose valuable heat and money. Some individuals forget to insulate the garage ceiling, allowing cold air to travel and possibly get up upstairs, in addition to the walls and garage door.

Also, ensure that the room on the second floor is well insulated.

Ways To Keep Bedroom Above Garage Warm

Ceil Your Garage

Insulated ceilings lower the amount of heat that escapes as it rises, but insulating an unheated garage ceiling can also help to reduce the chilling effect of cold air circulating beneath your feet.

Newer garages may have insulated ceilings, although older garages may lack them. Insulation is more likely to be present if the garage ceiling is completed with plywood or drywall.

To inspect, cut a hole in the drywall and peek inside with a flashlight, or take a sheet of plywood off the wall. If the ceiling isn’t done and there’s no insulation visible, or if cutting into the drywall or removing plywood reveals a bare space, new insulation might assist.

Adding insulation batts, blowing in loose insulation, or spraying foam to a lofty garage ceiling is usually best left to professionals. After that, drywall or plywood should cover the insulated ceiling. Address any draughts that may have crept in around the garage door while you’re in there.

Add Insulation Between Garage And Upstairs

You can increase the way your home insulates you from excessive temperatures even if you can’t modify how your HVAC system works. Insulation is the structure’s continuous thermal and air barrier to the outside world if you’re not familiar with the terms.

The envelope consists of walls and insulation. The more energy-efficient and comfortable the home is, the stronger the envelope is. Compared to the rest of your house, that room above your garage has a low-quality envelope, particularly insulation.

You can bring the envelope enclosing that space up to par with the rest of your house by installing insulation between your garage and the upstairs bedroom and upgrading insulation against your attic knee walls.

Install Radiant Panels

If in-floor radiant heating isn’t an option for your cold room, you can still use radiant panels, which are easily put on the walls and stylishly provide additional warmth. Far Infrared Heating is used to heat radiant panels.

The low-tech forced air and space heating systems with which we all grew up, on the other hand, work by heating the air around us. Consider how hot it can get sitting in the sun beside a window or how hot the sand or blacktop may get on a hot day. This technique consumes significantly less energy, lowering your heating bills while producing a tremendous amount of heat.

Garage’s Door Insulation Also Matters

Increasing the R-value of the garage door insulation is another way to make the room warmer. A few batt rolls attached to the garage door can help keep the space warm in the winter.

Remember that the better your garage is insulated, the warmer the space above it will be. Most garage doors should have an average R-value to be energy efficient.

Before installing any more insulation to your home, it’s usually a good idea to verify the local building codes in your area.

Seal Windows Appropriately

The whole room upstairs is the focus of the next few steps. Make sure the windows are well sealed, and if you want to go even farther, use heavy curtains to insulate and keep the heat in. Add rugs or fresh carpets to make a space feel warmer and more comfortable if the floors make it feel cold.

If the room has an attic, it should be accessible by a panel or pull-down stairs. To find insulation, you might have to cut through the drywall. Batts, blown-in, or sprayed-on insulation should be used in uninsulated spaces; matted insulation should be replaced.

You can add insulation batts if you have free access to uninsulated regions. If you don’t have access to a blower or a spray gun, a professional can insulate your home.


You can insulate the space over your garage using a few different techniques. When examining the methods listed, don’t forget to factor in the cost. The optimum solution will differ based on the size of the room and the weather in your area.

It doesn’t have to be the least favorite room for everyone. It can instead be a place where people wish to spend time.
