I have came across a warehouse full of white and tan material which appears to be Durolast or some type of Hypolan. The material is in rolls which are 7 feet wide. There are no lines or marks for plates or fastening on the material or any tabs to stretch the material. It has the reinforcement scrim in between the layers. To me the texture is the same as Durolast.
Does anyone have any idea’s to what else it may be? Is there any uncured flashing made that will stick to the cured field membrane? I was told that this stuff may cure and be unweldable if exposed to open air to long? Thanks for your help.
