Questions and Answers for GCP Applied Technologies Vycor enV-S 40 in. x 120 ft. Roll Fully-Adhered House Wrap (400 sq. ft.)

A:  Yes

A:  The installation guide states "may be exposed up to 90 days"

A:  This is a high quality product primarily used as a house wrap. I am not sure what you mean by a commercial building or how you plan to apply this product. If the building is of the same construction as a house, I see no reason why this product would not work as well. My suggestion is to verify with the building code for the location where this commercial building is being constructed and/or with the Grace Company (manufacturer of this product) directly. Hope this is helpful.

A:  I see no reason why you couldn't use it in that way. It is easy to apply if you follow the instructions. The adhesive is agressive & sticks to almost any surface. It is about as thick as cloth & has a textured surface on the non-adhesive side. Hope this is helpful.

A:  I don't see why not. Consider using smaller pieces than you think you can, and an extra set of hands. Att from sample panel - needs to be shorter cuts or more hands

A:  While it would certainly adhere to that material what you would have to watch is not pulling on it because I imagine it would easily tear loose by pulling chunks out of the foam. I think you would just have to take care putting it up. If running vertically I would think as long as someone held the top while a second person did the positioning, sticking and cutting you could probably pull it off with 2 people. The only good way to do it by your self would be to pre-cust pieces to length and install them like putting up wallpaper being careful not to pull it after adhereing it.

A:  Yes it can be installed directly over rigid foam. However I believe the rigid foam will negate the function of the enV-S as the foam is a hard vapor barrier and the enV-S is meant as vapor management.

A:  As long as there is no frost or moisture on the surface you are applying to temp probably does not matter.

A:  Per manufacturer's installation guide: "Vycor® enV-S™ weather resistive barrier may be applied only in dry weather when air and surface temperatures are above 40°F (5°C)."

A:  The instructions say 40 degf min. So evidently the adhesive is good over quite a range.

A:  The box-side instructions say 40F or more - see pic
