How to insulate a garage from walls to ceiling?

Are you reluctant to go into the garage in cold weather when you have to drive your car almost every day for your various trips? Here’s how to end this ordeal once and for all.

Start by insulating your garage walls

Insulating garage walls can be done with the same materials used to insulate your interior walls. All you have to do is choose the one that best suits your needs and the performance you are looking for. These insulations can exist in bulk, in panels or in rolls. Prices vary from product to product and from supplier to supplier.

You will install them between the wall and a partition, which will cause you to waste a little space in your garage, but always for the good cause. The thickness lost will depend mainly on the type of partition installed as well as the thickness of the insulation you have chosen. Also, take this into account when choosing your insulation. For example, you can opt for Placopl√Ętre panels covered with polystyrene or for mineral wool inserted between the walls and the Placopl√Ętre panels.

Continue with garage ceiling insulation

Insulating the ceiling of your garage can not only improve your thermal comfort in this place, but it will also save you around 10% energy. It is in any case proven if your garage is located under one of the rooms of your house. To properly insulate the ceiling of your garage, the best option is to install a suspended ceiling on metal rails or wooden cleats

If you have a fairly limited budget, opt for a stretch ceiling instead. Then just fill the gap between the ceiling and this false ceiling with a good insulator such as glass wool, rock wool or better because it is more ecological, hemp panels or cellulose wadding. It would be perfect if you can get within 15cm of space between these two items. Indeed, the thicker the insulation used, the higher the thermal and acoustic insulation obtained.

Finish with the insulation of the garage door

So that the heat accumulated in your garage does not escape by any means, it is better to insulate the door as well. This is all the more advisable as this room is not heated. If you have a garage door that is already equipped with waterproof peripheral seals, the problem no longer arises. Otherwise, you must find the solution that best suits the situation.

If you don’t want to change your garage door, buy insulation kits and install them directly on it. These kits are composed of foam adhesive plates that are suitable for all kinds of doors, sliding or not, motorized or not. If you want to swap your old door for a more suitable one, choose one made of metal and aluminum and lined with polyurethane foam. This type of door is particularly recommended for its ability to protect places from heat and cold.
