  • Fire proof covering for styrofoam??

    Hey guys!
    I finally gave up...took the afternoon off yesterday and screwed styrofoam to the panels on my overhead garage type door in my shop.
    Also screwed a big piece to the man door. Wow! It is nice and toasty in the ol' shop now...

    But...I don't want it to get too toasty. This being a fab shop and all. There's always lots of sparks flying in here.
    I need something to cover the styrofoam with so it doesn't catch on fire.
    Any ideas?
    Thanks!

    My garage doors are recessed for insulation (added). I had always thought that I would cover the insulation with sheet metal. To keep the little embers from jumping into the cracks between the sheet metal and the garage door I was thinking of sealing with silicone.

    The only thing that a fellow would also have to check is if the garage door opener will pull up the extra weight. Also, the top of the newer garage doors should have a bar or angle running the length to tie in the garage door opener to. If not they flex and fail over time.

          If it's just spark control and not sustained flames on it wouldn't ordinary laytex spray paint work better then having nothing on it?

            Here is the lazy man approach. It's even Canadian.

            You want one of the latex based coatings for covering foam.

              Slightly off subject, but many years ago I flew model airplanes. I used to make wingtips from Styrofoam, and covered them with silk or paper laid on with thinned down white glue. Several coats would seal the Styrofoam from the effects of the butyrate dope we used to seal the wing covering with.

              You could do something similar using a cloth applied with thinned down white glue applied with a brush.

                The only thing I can think of would be Aluminum roofing flashing, I know for a fact that they come in 24" x 50' rolls. that should be enough to cover your door, and it would be light wieght as well as spark resistant.

                  Torker what about the aluminum covered styrofoam to start with? (siding material or sheathing) In your shop it would probably take a spanking after time but it is tough enough to deflect the nastiest of welding spark...

                  If you wanted to toughen it up your not limited to latex paint as you wont have to worry about chemically melting it Soooooooo --- throw on some epoxy paint after your done? But dont paint the edges...

                    Russ has already installed the foam.

                    Doesn't anyone read the earlier postings?

                      Very thin (0.010" or 0.016") sheet metal as used for covering industrial pipe insulation. Available in aluminum, stainless, or even dimpled galvanized steel. Normally sold in 36" x 100' rolls, but if there is an industrial insulation supplier in your town, he would probably cut it to your specified lengths. Attach with sheet metal screws.

                        Ahso..I never thought of paint! I'd actauly like to paint it and cover it with sheet metal.
                        Flashing...yup...that would be good.
                        I really don't like this but I had to do something.
                        I want to replace this door with a higher one that slides open sideways but that'll have to wait til spring now. Thanks guys! I'll phone my paint supplier and see what she has for this.

                          Whoooh there Stymie,,, Actually I think you need to re-read the postings ---
                          The very reason I brought up the aluminum coated foam house sheathing is due to the fact that he did state just foam, So if you add some deductive reasoning skills to that (which i might add something that you are running a little short of these days) And you consider his entire topic to due with fireproofing the FOAM and welding sparks setting it off then my suggestion is right on the money -- and thats regardless if or if not he already has the aluminum coated foam due to the fact that he didnt mention it (sorry, im not a mind reader)
                          Now -- getting on to your site -- check out the epoxy based coating and its insulating properties rock --- not only that -- its rugged as all get out (they use it on ammunition crates and warheads)

                          "Flame Control No. 46081 Thermal Insulating Intumescent Epoxy Paint is a two component (catalytic epoxy) thermal insulating, semi-gloss intumescent fire retardant paint. This product is manufactured in accordance with the United States Military specification Mil-C-46081S. The coating is designed for use on Naval and Marine vessels, military and commercial aircraft, fuel tanks and storage vessels, ammunition crates, missiles, warheads and other surfaces where it is essential to obtain the maximum insulating protection under the most severe fire conditions."

                          The reason I brought up the aluminum covered foam is two fold, one, as is its superior to just foam for flame retardant -- two - if he goes to coat it he's not limited to latex paint, he can use epoxy and it won't melt the foam board...

                          Got anything else you want to try and make some common sense out of or is that enough for today,,,, Happy new year Ev (spank -- spank)

                            How about latex paint or white glue with cotton fabric applied wet. Adds spark protection and stiffens up the foam too.

                            Thin sheet metal is better but tweak the sprint for the added weight,
