Inquiry (采购产品): foam dispenser I am a contractor and I would like some information on your spray foam system. I would like to know the r-value of the foam and the thickness I would need to use. I've seen roofers using this system and I am very intrested in maybe buying one to add to the services I offer my clients. I am a general contractor. Please e=mail me some information if I would be able to use this in a residential manner. Thank you for your input. **** Hidden Message ***** Jesus Carreno 100 County Rd. 84c Santa Fe, NM 87506 USA Company: JC Remodeling Title: Owner E-mail: gueracarreno@aol.com **** Hidden Message ***** gueracarreno@aol.com
