    Well finally I have what must be the most expensive pink foam in North America. I hunted all over Florida to no avail. It just doesn't seem to be available in this part of the country. So, I had my son-in-law ship me some from Ontario by Fedex for a small fortune. Now I have more than I need and am willing to share it, if we can agree on a price, with anyone in the same quandry that I was. I have both 1 and 2 inch.

    You seem to be in the same boat as I'm down here in Brownsville...I can get the 3/4" pink (not very good IMO) but can not get any blue foam....Oh well....the tribulations of having to live in a place where the avg. temperature is in the upper 70's'- low 80's....:mrgreen:

    Despite what some people want to tell you, Blue foam and Pink foam are the same, the color is a trademark.

    And you and build it up as high as you want and use liquid nail to hold it together.

    I've got some blue foam from a building contractor friend (very little as they'd already finished the job...) which they brought in from God knows where. That shapes very nicely and is a lot less dense than the pink foam I get here, which doesn't shape real well.

    I would imagine...

    ...the "market" determines where blue or pink foam is required but when I go to my local lumber guy- in the northeast- they have both and it's labeled in English and Spanish in case you can't read so good. Isn't pink one guy and blue another guy- manufacturer? R-factors and such..

    Any contractors wanna share the secret of pink vs. blue?

    I always thought there was tension between pink and blue and then the next thing you knew there were kids crawling on the floor. Then it's Valentine's Day- another massacre.

    Uhhhhhhhhhhhhhhh- My heavy shoulders.

    John, If only I'd known. I could have fitted a few sheets into the motorhome.
    Mark: I think pink is from the company that advertises with flamingos. They also make pink fiberglass insulation.

    John, "Atlantic Foam" here in Sanford Fl. sells Dupont pink foam in 4x8 ft sheets in 1, 2, 4 inch thicknesses. If you contact them, maybe they can assist you in finding a distributer in your area.
    Oops, just reread your post. Wish you would'a asked earlier.

    The colour of extruded styrofoam is strickly for brand identification.This stuff is made in Gray,Yellow,brown,pink,green and blue.There is only one formula for the stuff.if you got ahold of some that was dificult to work with you simply got some from a bad batch.

    I could never understand why the stuff is not usually available in the warm climates.I mean afterall it's main purpose in life is to insulate and I know you guys sometimes need protection from the heast. :confused:

    I think that may have to do with how the foam is typically used. New construction here is usually 2x6 or 2x4 exterior walls with fiberglass insulation. Attic spaces may be either fiberglass or blown-in cellulose. Those methods are the cheapest, easiest to install, and perhaps the most effective for those types of applications.

    As I understad it, the foam is typically used to insulate walls of basements, or perhaps retrofitting to the exterior of an older house beneath new siding. Basements are extremely uncommon here in arizona. My guess is only 1 out of 1000 houses has a basement. I suspect florida is the same way. Basements were never needed here because houses didn't have non-forced-air furnaces because heating was not a priority and forced-air technology was available before most houses around here were built.

    People do use foam around here for the retrofitting of older masonry houses. Foam is attached to the exterior wall, and then the foam is coated with stucco. The foam used may be the pink or blue type in 1" sheets, or more commonly a yellow foam sandwiched between two sheets of reflective foil. The foil acts as a radiant barrier, and is more effective in areas with high sunlight intensity. The only foam I can find around here is the white beaded foam, blue foam in 1" thickness, and the foil-clad foam. I simply do not see where there would be much demand for 2" pink or blue foam around here based upon typical construction practices.

    Also keep in mind that using foam for a layout is a relatively new idea. I was mostly out of the hobby between 1995 and 2004, and prior to 1995, very, very few people made layouts out of foam. Now, the majority probably do. One can still use the old plywood method, and that is still what I prefer. It's stronger, and better suited to those of us who handlay track. I still plan on using foam to form my mountains, though.

    Foam has its advantages - it's lighter, it is less messy, and quicker. It's better suited to those who live in apartments or condos and don't have the space to cut a sheet of plywood or who don't own or like to use power tools.

    Foam is used to insulate against the Frost line, I northern places (most of northern US and in Canada:canada1:) the frost line is pretty deep so we use alot more of it.

    It is placed against the foundation/basement, some times on both sides. the farther south you go the higher the frost line until it doesn't exist.

    The foam is used to keep the moisture from collecting on the cold surface of the Cement that is transferring the cold from outside.

    In places like florida there are two reasons you do not have foundations or basments. A) you do not have a frost line, in the north we need the foundation to be below the frost point so the house doesn't move when the ground freezes. The ground doesn't freeze below say 5 feet. So our foundation sits on dry none frozen ground at 7-9 feet below the surface. B) your water table is to close to the surface.

    Now in more northern places like Alaska, Yukon, N.W.T, Nunavut, northern Quebec, Labrador, Greenland ect. The ground stays frozen and the top layer thaws in the summer (permafrost) In these places they need to Place the house on posts that are sunk down deep into the frozen ground, then build the house above ground so that it doesn't shift when the ground thaws. In this area the first floor is insulated underneath.

    Hope this helps.

    I wouldn't even say it is a matter of the frost line. It is a matter of basements. There aren't any... Finding a basement in Florida is like having a 90 F degree day at the arctic circle.
    And the water table isn't too close to the surface.... it IS the surface.

    As for Extruded foam in Florida... building supply stores can order it for you, and some do actually stock it (though not displayed). Panama City and Pensacola Home Depots had 3/4" and 1" pink foam stashed away on the top shelf of the building materials area of the store, but didn't have any available down at 'customer level'. I had to ask for it.
    A Lowes and a Home Depot store in the Fort Walton Beach area both ordered 2" extruded foam for me, free of delivery charges. (as long as I picked it up in-store.) I have friends in both the Orlando and Tampa Bay areas that have ordered 1" and 2" through Home Depot, as well.

    I understand things can be different in different areas, but 99% of the time.... If they can make a profit by getting the product you want - they will.

    sign1 I work well above the Arctic circle, and i'll let you know that during the Summer alot of the mainland is above 90F which is 32C. This summer when i was in Inuvik, Norman wells (just south of the circle), Baker lake, I had many days that where 30C at 2am (midnight sun). And Inuvik is only a few miles from the Arctic ocean.

    In 2007 I was in Norman wells, we were fighting forest fires, and I swam in Jack fish lake on Canada day (July 1st). Norman wells is west of Whitehorse, north of Yellow knife and south of Inuvik.

    I have seen many days in Inuvik which is just inside the Arctic circle that where well above 30C.

    Dave R. If I'd only known about foam being available in Sanford I would have driven over. Well maybe next time.

    As far as having Home Depot order it, I tried that and they were quite willing. The only catch was that I had to buy 96 sheets of 1" and 48 sheets of 2". That was just a bit more than I needed.

    Thanks to everyone for their response.

    A lot of the foam used in Florida is architectural decoration. When you see some of those multi-million $ homes, the columns and such are made of stuccoed foam.
    BTW, if y'all cut foam with a hot wire, make sure you're well ventilated and white foam is very toxic when hot wired, I wouldn't try it.
