zed1 Posted February 25, 2012 Report Share Posted February 25, 2012 I am refinishing the heater box and after I removed the heater core I noted that there was black foam between the core and the box. I presume that the foam serves as both insulation and an anti-rattle barrier. After searching the internet for aftermarket foam substitutes, I stumbled upon the Dow Great Stuff product. The yellow product is available at local home builder warehouses. The GREAT STUFF™ Pond & Stone (http://greatstuff.dow.com/products/pond-and-stone/) is the same product in black. I spoke to a Dow representative and was told that all Great Stuff products are stable up to 240 degrees Fahrenheit. Has anyone found a substitute for the factory black foam? Has anyone used Great Stuff at higher temperature? Thanks, Keith Quote Link to comment
datzenmike Posted February 25, 2012 Report Share Posted February 25, 2012 I think mostly it's to prevent air from going around instead of through the core. Could be wrong but no real need to insulate. I just used foam rubber and cut to fit. As for temp, the highest it will get it 212F from the water, not even that. Quote Link to comment

bananahamuck Posted February 26, 2012 Report Share Posted February 26, 2012 I just used regular old foam from the fabric store. Hasnt melted yet. I think that`s what my brother used on his....cheap and works. Camper shell foam tape for me ... easy to get , cheap and works good and if not thick enough stick more on.. Quote Link to comment
