How to add insulation to garage roller door?

[JJT2021]

I have 2x garage roller doors and I am trying to find the right insulation to cut down temperature. Everything is about panel doors but it is hard to find about the old fashioned roller doors. I am also looking at the gap on top of the roller door which allows dust and heat to come through.

Hi @JJT2021,

Due to the nature of roller doors, any insulation you add to the back of them would need to roll up with the door when lifting. If you were to install insulation of a significant thickness, it could bind in the roll and prevent door usage. 

Do you intend to continue using the doors? If so, there is a chance that you could use GI Building Sciences 10mm 1.5 x 20m 30m² Reflecta Guard Plus as that is a thinnish product. You'd still need to check the space between the rolled layers to ensure any product within them doesn't get damaged or bind the door. Check out @bluesue's discussion on How to install Ametalin liner. They ended up using the GI Building Sciences product on their roller door.

You might like to supply some images fo the gap at the top of the door so our members have a better understanding of what you're working with. Let me know if you need a hand uploading images.

The first step would be to try and minimise this gap as much as possible by installing a solid panel. From this panel, you can attach garage door seals to further close the gap.

Please let me know if you have any questions.

Thanks, for the advice, I will post pictures when I start the job.

Helo @JJT2021 welcome to the Bunnings Workshop Community, I think a brush door seal might be exactly what you are looking for, the flexibility of the brush won't impede the open/close action of the roller door like a fixed panel would, this will address the draft part of your problem.

For thermal control strips of thin adhesive insulation could be added to the outward cavities of the roller door but I wonder if it would be more effective to suspend thermal blocking curtains on the inward side of the roller door... a shade sail out front of you garage would also keep sunlight (and thus heat) from reaching the roller doors in the first place.

Hello @DIYGnome 

Thank you for sharing your knowledge and experience with our community. 

Let me tag @JJT2021 to make them aware of your recommendations as well. Your suggestion of using the Moroday Silver Angled Brush Garage Door Seal is ideal and should cover up the opening at the top very well.

Hi @JJT2021 

I have a main double width panel garage door and at the rear, a single roller. I used this product along the top of both. The roller door gets a lot of weather and wind. I solved that issue by installing the same product in-between the vertical guide track and wall of the garage. The brushes follow the profile of the roller door perfectly during operation and close with no impedance. Since then, I get zero weather coming in and just a very slight breeze on very strong wind days.

To cut down any radiant heat on the door itself, you would need to install something like a blockout blind on tracks in front of the door. This would keep direct sunlight off the roller, and provide an additional layer of insulation between the roller and blind, and still allow for the doors to be used as normal.
