The great thing about garage insulation and home insulation is that it reduces heat transfer. One disadvantage of garage insulation, in particular, is that it can sometimes break down, causing issues such as severely fluctuating temperature levels.
As a result, you may find it challenging to keep the temperature in your garage at a steady level. And that’s crucial for slowing down and stopping corrosion, especially on vintage vehicles.
That’s just one sign you need to replace the insulation in your garage, but what are the other signs?
High Heating Costs
It can be a bit tricky to determine why your heating bills are higher than usual as the cause could be due to many things. However, here are some ways to help you narrow down the cause to your garage - specifically, your garage insulation:
There is no discernible temperature fluctuation in your home;
It never feels drafty from any doors or windows inside your house;
You aren’t using equipment that consumes significantly more energy than usual;
Your garage always feels colder than the rest of your home.
It’s never fun to pay more than necessary for your heating bills. However, given the above clues, the source of the problem could well be failing or lack of insulation in your garage.
Your Garage Always Feel Drafty
When you walk into your garage, does it always feel ‘windy’ inside - even with the main garage door closed? If so, it makes sense to try and trace the source of the draftiness in your garage.
One of the first steps is to check around the garage door and all door and window frames inside your garage. Next, you should turn your attention to your garage insulation. Do you feel any drafts coming through the insulation?
If you feel some air coming through the insulation material, it’s time to get it replaced.
Lots of Condensation
Garage condensation can occur whether you live in a hot or cold climate. The reason condensation in your garage happens is because of the excess moisture inside of it. One classic cause of excess moisture is when you run unvented appliances in your garage.
But, another leading cause of condensation is due to garage insulation. For example, improperly-installed insulation material, especially in the garage roof, will turn your garage into a moisture trap.
You should only have insulation installed on the walls of your garage and the garage door itself. Never install any on the roof.
Visual Breaking Down of Garage Insulation
Last but not least, if you do a comprehensive visual inspection of your garage insulation and find it has broken down in places, it’s time to get it replaced. There are many reasons why garage insulation can break down, such as:
Poor quality materials - inferior insulation products have a short lifespan;
Poor quality installation - it makes sense to have insulation installed by professionals.
Age - good-quality insulation lasts a long time, but it doesn’t mean it will last forever.
