Benefits of insulating your concrete garage

A garage is very rarely used for the car anymore, majority of people use their garage for other uses such as a storage unit, a home gym and even an extra room for their home. Even though people use their garages for these functions, they don’t take care of it like it were another room in their house, the garage is often neglected. But it is so important that you insulate your garage for multiple reasons – here are a couple of them.

Money saver

Heating and cooling costs are rising all the time, and with an insulated garage, it will cut your heating and cooling bills – saving you more money as time goes on.

A garage that isn’t insulated can’t retain cold or warm air, meaning when you try to heat it up in the winter, the warm air will escape through the walls and the door, and when you try to cool it down in the winter, the cold air will also escape.

If your garage is connected to your house like most, and it is uninsulated, it will suck the hot and cold air from the rest of the house – which also leads to higher energy bills as you need to spend more money on heating and air conditioning.

Your items are safe

Insulating your garage protects all your belongings safe, especially your car if you still keep it in the garage.

A car battery is vulnerable in the hot weather, because it contains liquid and hot weather leads to the evaporation of that liquid, causing the battery to stop working. But it is also vulnerable in cold weather – if your battery gets too low, it slows the chemical reaction, leading to the car failing to start.

If you insulate, it will stop the temperature getting too warm or too cold, which means the items inside your garage are safe. For a top-quality concrete garage, contact a company such as Dencroft Garages – their experienced, friendly team will be happy to help.

The garage door

You will want to weathers trip the garage door, but insulating the actual garage door is a little bit harder.

There are many ways you can insulate it by yourself, but they aren’t good long-term options – garage doors open and close all the time, and fold in different places, therefore batt insulation or spray-on foam insulation won’t work well.

You should look at investing in an insulated garage door, unless you want to keep insulating your garage door over and over again.
