Adhesive for foam insulation

I am setting about insulating the metal up and over door to my garage/workshop

I have some 25mm foam insulation sheet, not the foil covered type, and intend sticking it to the inside of the door.

What do you suggest will be the most successful as anything with a solvent is likely to attach the foam - perhaps high viscosity PVA like NoMoreNails or Silicon sealant/adhesive?

Isn't that solvent based though and likely to attack the foam?

I've used contact adhesive for foam backed vinyl. An aerosol spray-can is very easy and convenient for applying adhesive onto the foam and the normal liquid adhesive applied to the solid surface.

Contact adhesive or non solvent 'grab' adhesive. Dead light so nothing fancy needed.

Everbuild do one called "Dry Fix FR" made for sticking insulation to walls etc.

"foam insulation sheet" is a bit too vague. One such might be expanded polystyrene which is going to be rather different in its susceptibility compared to polyurothane or some other types.

It is expanded polystyrene - this stuff **LINK**

Thanks Nick

I think there is a special 'foam in a can' for eps specifically. Have a look at all the ones available on teh Screwfix website.

Nick, not sure I'd want to use expanded polystyrene in a garage/workshop location even when the EPS contains fire retardant. Have you had a look at Kay Metzeler's safety data sheet?
Some points therein:

• Extreme caution must be exercised when storing, shaping and applying EPS to ensure total protection from flame and/or fire.
• EPS should be kept away from all substances of unknown composition that could contain solvents e.g. paints or adhesive.
• Avoid all sources of ignition: sparks, open flame.
• Incompatible materials: Solvents e.g. paints or adhesive / Creosote / Diesel / Heating oil / Petrol / Paint thinners / White spirit

Some years ago, I went for this product to insulate the inside of steel garage doors:- https://www.weatherstop.co.uk/collections/garage-door-insulation

Very effective, it seems to be polyethylene "bubble sheet" inside a double layer of aluminium foil.

As with everything nowadays, there is far more to learn than you ever wanted .

Interesting topic though.

I'm going to use paintable expanding foam in a can to cut down the rattling from belt cover on mill/drill

this might work but I've not used it myself

That's the one I mentioned earlier works with PU and EPS boards etc. details

Have you bought the insulation yet as the weight of thick insulation may make the door very heavy and the spring actuator may not work. I did something similar and found thicker insulation very wealdy to fasten to the door and too heavy. I bought some 12mm foil backed insulation and found that it slides into the framework supports on the inside of the door and other than a few bits of foil tape no adhesive used. The insulation value is more than adequate and the worksop is loads warmer and I can open the door!

I did this to the inside of my garage door years ago - I used to condensation on the inside (steel door), and I had some spare 25mm foam, so I just stuck it to the inside of the door using the spray on foam builders adhesive mentioned above by Jason - works fine.

I used 25 mm thick foam on the garage door & it worked fine but you have to watch the weight & adjust the springs to compensate.

You can simply test EPF for fire yourself, break a bit off and try to burn it, take the flame away and it should go out.

Aldi locally (Huddersfield) currently have this insulation wrap on offer, which is quite lightweight & inexpensive (£9 for 4.5 square meters). A couple of rolls found their way into my trolley yesterday, so I'll see how effective the stuff is on steel up-and-over garage doors in due course.

I'll use PU adhesive from Toolstation "dot & dab" style to attach it & hope it never needs to come off !
