Hi all,

I don't think that this is the best forum to do this on but I figured I'd give it a shot. I use my garage for various hobbies and now that winter is here, it is freezing! I'd like to insulate it with that pink stuff (or an alternative), however, I'm not so sure how. I asked some specialist and they have hosted me 😅😅...

So I'm wondering if any qualified people on this forum (or any other site) could point me in the right direction to get this done? 1000511232.jpg1000511233.jpg1000511234.jpg1000511235.jpg
 
Yeah, isoboard is going to be the simplest.. especially for installation, where you can use some adhesive and stick it directly to the roof sheets..
 
Isoboard is a easy diy for the ceiling but that garage door is still going to let in a lot of cold.
 
Another option is to just fit Syrofoam / polystyrene boards between the roof beams. I know someone that did that and it worked well. He measured up and had the "panels" pre-cut. Then used a trim piece along the beams to hold the boards up.

Not sure how the costs will compare to Isoboard. Also depends on how you want the finish to look.
 
Ceiling is straightforward but I can't see any way around those doors if you want to keep them. We bricked ours off and turned it into an office.

Isoboard/polystyrene roof panels between the rafters, made a big difference in a previously cold room at my place.

And maybe curtains somehow in front of the metal garage doors.
 
what are you hoping for after doing all this? a nice warm garage.... it's not going to happen, ever.

1) now you've insulated the ceiling a bit (and I say a bit because you'd need to seriously insulate anything to be effective) you'd probably end up making it colder as the hot tin roof can't radiate heat down into the garage now. Just stand on a ladder and feel the roof at lunchtime in winter
2) the garage doors are 10x worse with regards to cooling (cold air sinks) and the tin roof in winter gets nice and warm with the sun
3) feel the concrete floor? unless you lay styrofoam or something that's going to stay ice cold
4) windows?
5) access doors besides main garage door?

The money and time you'd spend doing the ceiling would be a waste. You might as well just get a nice heater inside, running costs would be way cheaper.

Yo! So the plan is in bold below:

1) now you've insulated the ceiling a bit (and I say a bit because you'd need to seriously insulate anything to be effective) you'd probably end up making it colder as the hot tin roof can't radiate heat down into the garage now. Just stand on a ladder and feel the roof at lunchtime in winter - My real issue is in the evenings, that's when I want to use the space. In winter, it gets to sub 10 and that's not fun and in summer it is BAKING hot
2) the garage doors are 10x worse with regards to cooling (cold air sinks) and the tin roof in winter gets nice and warm with the sun - I know that there is not much I can do about this, I stay in a complex so replacing the garage door with a solid wall isn't possible, but I have used expanding foam in the crevices that I have seen.
3) feel the concrete floor? unless you lay styrofoam or something that's going to stay ice cold - I do plan on getting those rubber mats, again not the perfect solution but my neighour has it and it looks good and will make moving across it in a rolling chair easier.
4) windows? - No Windows (fortunately and unfortunately)
5) access doors besides main garage door? - This is part of another project in my place.

I use the garage mainly to gym and for hobbies like 3d printing. Gyming happens early in the morning (kettlebells at 5.30 and 5 degrees isn't fun) and neither is painting in the evenings. So for me this is all to (hopefully) get the space to a more comfortable temperature. I don't expect it to be as comfortable as the rest of the house.

Thanks to all those who replied, I will definitely look into it! Hopefully it is something that I can do myself. Can someone perhaps link me to a guide that can help out?
 
I would paint the outside roof black and put these rubber floors throughout.


For me being boiling hot is better than being freezing cold.
