What is the Thickness of Insulation on Roller and Sectional Garage Doors?

Posted on: 24 February 2021 by Horizons Group Ltd

Remember when garages were only used for car storage?

No? Actually, that’s a fair point – this is something so few people do these days. Modern garages are far more likely to play the role of storage room, office, workshop, or home gym.

This has influenced the design and construction of garage doors quite a bit. Most notably, it has called for far better insulation and the more widespread use of roller and sectional garage doors.

But just how thick is that insulation? Can it really help you use the garage for extended periods of time?

Why is garage door insulation important?

There are a couple of reasons garage door insulation is so important. Firstly, it’s because you may want to spend a significant amount of time in there.

Whether it’s working out, writing your latest novel, or putting the finishing touches to your self-built wardrobe, you’ll want to feel comfortable. Garage doors without insulation will let the cold air penetrate that space and make it far less palatable as a room in which to get stuff done.

Secondly, if your garage is attached to your house, it will have a considerable impact on the energy efficiency of the home. If it’s constantly letting cold air in and warm air out, that will contribute to larger heating bills – simple.

Imagine if your bedroom is directly above your garage and you don’t have an insulated garage door. That’ll probably make it one of the coldest rooms in the house.

We shouldn’t forget noise isolation, either. An insulated garage door will do a far better job at keeping noise in – and out – of your garage, which might be an important consideration, depending on your use case.

Garage door insulation thickness

Modern garage doors combine ease of use with great insulation, if you go for that option.

For the two most common types of garage door in this category, the insulation available is usually as follows:

  • Roller garage doors: 12-15mm of insulation
  • Sectional garage doors: 42mm or 67mm of insulation

Sectional garage doors offer more insulation because of the way they’re designed, but that doesn’t make roller garage doors any less efficient.

Some benefits of having an insulated garage door

Insulated garage doors offer countless benefits over those which don’t have any form of insulation.

They’re tougher and far more capable of standing up to whatever Mother Nature can throw at them, but there’s more:

  • they are far more energy efficient (this bears repeating because it really will make a huge difference to your home and ability to use the garage);
  • they’re really quiet during operation because of that insulation; and
  • they’re typically longer-lasting, simply because of their construction and ability to better deal with the elements.

We can almost guarantee that you weren’t thinking of an insulated garage door until now. But if a sectional or roller door has been in your sights, it really does make sense to explore this option, because you’ll be surprised by how affordable it is over non-insulated doors.
