FL 2000 is a closed-cell spray applied foam, which was developed using Environment Canada's approved next generation blowing agent. The foam is tinted orange to signify our FL 2000 Canada spray insulation product line. When installed following application guidelines the spray foam insulation adheres tenaciously to framing members and substrates. FL 2000 closed-cell spray foam provides superior energy economy and durability while significantly reducing unmanaged moisture and air infiltration.
