Ask A Trader: What’s The Best Way To Insulate My Garage?

As we move into the colder months of the year, you may be feeling the effects of having no insulation in your garage. If your garage is attached to your main home, it’s likely that you’ll be feeling the effects of this a lot sooner than those with a separate garage, as cold can permeate through the walls into your home and heat will be drawn out through the areas with no insulation. This can cause mould problems, condensation and uncomfortable temperatures in both the winter and the summer in rooms which adjoin to the garage, so implementing some kind of insulation can really help with your comfort and your bills.

What Are The Benefits Of Garage Insulation?

Garage Energy Efficiency

Garage insulation can have a number of benefits for your property and for your wallet, particularly if you spend a lot of time in your garage or if it is attached to your main property. If you store perishable items or vehicles which need a little more TLC than usual (such as vintage models) then you can also benefit from garage insulation. This is because, by insulating your garage door (and walls, if you want/need to) you can help to regulate the garage temperature, ensuring that it doesn’t get too hot or too cold. This protects the items in your garage and means that heat is not lost from your main home, thus pushing heating bills up.

Can I Use DIY Insulation?

Many people insulate their garage doors themselves, but this can be risky if you don’t know exactly what to do. With up & over garage doors, adding insulation will change the overall weight and size, potentially causing difficulties when opening and closing the door, and throwing the opening mechanism off balance. In many cases, it would be more beneficial to replace the door with a new one which has insulation built into the door itself, and to ensure it’s fitted properly into the gap to minimise draughts and damp from getting in.

Should I Insulate My Garage Walls?

If your garage is part of your main home, then insulating the walls can make a huge difference to the temperature inside the garage and the temperature of the rooms which adjoin it. If your property was built prior to 1920-30, then it’s likely that you’ll have solid walls. Properties built after these dates tend to have cavity walls. An easy way to work out which type of wall construction has been used for your garage is to look at the patterns in the brickwork. If the bricks are all the same size, and are simply layered on top of each other equally, then your walls are likely to be the cavity variety. Bricks which alternate between large and small indicate that the wall is a solid wall, as the smaller bricks are actually brick ends, as the bricks have been put in different directions to make up the width of the wall.

Solid walls are difficult to insulate and will need external insulation, where a dummy wall is built and insulation used to fill the gap. This can reduce the size of your garage somewhat, so it’s important to work out how this will affect your use of the garage. Cavity walls, if not already filled with insulation, can be filled relatively easily. Many new builds in the last decade or so will already have this insulation built-in.

Which Garage Doors Are Already Insulated?

Having a garage door fitted which is already insulated is a good way to make a positive difference to your garage. Not only can regulating the temperature in your garage help you to save on energy bills, but it also ensures anything you keep in your garage space will not be adversely affected by extremes of hot and cold, damp and debris.

Here at Evander, our entire Sectional and Roller range of garage doors come with built-in insulation as standard. Timber garage doors, whether up & over or sectional, are naturally insulating and will use the power of solid timber to ensure the temperature does not fluctuate too greatly.
