How to insulate brick garage with flat metal roof?

[EskapeShare]

Hi all,

I’m keen to make this garage space more comfortable by insulating. I’m thinking of foilboard insulation for the garage door and roof. 

What I am struggling with is what to do with the walls. The walls have an additional layer of bricks, (pillars), where the beams that support the roof are. There are 5 of these pillar every 1.8M on both sides.

I was thinking of building frames and attaching them between these brick pillars and adding wall insulation only between these pillars. I was just going to have only plywood over the pillars. Will this actually make any difference to the climate inside the garage?

I lose too much space if I insulate over the brick pillars.

Another question, do I new to put sarking on the brick wall before putting the frame up and installing the wall batts?

I would greatly appreciate any advice.

thanks,

k

Hello @EskapeShare 

Your idea of building a timber frame to hold the insulation in place is an excellent idea. If you wish to install sarking, I propose building the frame first and attaching the sarking to the back of the frame before attaching it to the wall. Since you are building a frame, I recommend using standard batts rather than the foil board as it has a greater R insulation rating. In regards to the pillars, I suggest covering them up with Ametalin insulation and clipping it to the timber frames that are to the left and right of it. 

Here is a link to our best advice: How do you add insulation to a garage or shed?

Just a friendly reminder to our New Zealand members that the use of foil insulation and sarking products is prohibited.

If you need further assistance, please let us know.
