Draught proofing a garage roller door

[JOEPRO]

This roller door was fitted about 20 years ago. There has always been a 2 inch gap all along the top of its 4.5m width.

Having just installed a China diesel heater I wanted to give it a half chance and finally address this gap. It may also improve / reduce noise transfer in my built up area when working at weekends.



First problem was the render was all over the place and had to be ground back level. I also put a bevel on it to help reduce wear on the brush





I used this stuff from Screwfix which was good value IMO



Trouble was I did not want to be drilling overhead on a RSJ beam 20x times. So I elected to add on mild steel tabs cut from a scrap galv strip



This meant I could then offer it up and arc weld to the beam. I don't arc weld often - but when I do it's terrible!! I'll blame the cheap welding rods.



The cavity wall and beams will be insulated and closed in soon with a cembrit board. The welds are crap but holding it strong at least.

I placed the brush so it was just touching the door with no pressure when closed. I can open and close the door easily. The door does go back out a couple cm when raised so it's important to consider that.

Thought I would share this idea and how it worked out I think this is probably a common draught source in most garages

@Arc Tourist also had a great idea of using carpet if he wants to share it here and any other suggestions anyone has please

The side tracks are not great but don't think there is much I can do about that. It is a single skin non insulated door. My other garage has a recent new insulated door it is fully draught proofed when installed and a great job.

Spatially in this garage however only a roller shutter fits.

Didn't someone post this issue a couple of weeks ago ?

Yes carpet was mentioned but wouldnt have worked for me.

It was a post in another general thread. I searched and could not find a thread on this subject hence here it is.

Got the pedestrian door done last night also

Screwfix has cheap strips for that too

Yes I did. Brushstrip. Just fitted it to the outside of my roller, had it fitted to the inside already, stopped 90% of the darfts, so wasnt expecting much of a difference. I wish I had done it from the get go. Its made a big difference. cost about 50quid

top of mines done with carpet ,,, but inside I have a heavy wool serge rag covering it all from roof to floor and its toasty and fire retardant too.
Heavy wool serge is the black backdrop you see at concerts and stage sides etc , its like a very very thick blanket its great , but anything that traps a layer of still air would do ,,, couple of old duvets etc ,,, the rag and the mat are a pain though as it slows down opening the garage , but as the bikes dont go out in the winter its not too bad.

I'm now looking at installing brushes on the side tracks of my rollup door, which should be easy as they are attached to steel jamb's concreted in, in between cavity walls.

I have used roofing rubber, make a 4" loop, and fix with an aluminum strip full length, stainless screws.
