32、 shall provide theproper installation procedure. Type 1 phenolic foams maycontain some compounds which may promote corrosion in thepresence of liquid water.As far as can be ascertained, there arecurrently no directly applicable ASTM corrosion tests forphenolic foams.

35、As Type II insulation is produced with integral vapor retarder facers, the orientation of the facer is important in preventing moisture penetrationinto the insulation and the water vapor permeance of the Type II faced insulation is valid as long as the facer does not fail.Property Unit Type I Type I
