Questions & Answers

Can I use glue on this

Asked by: Mel
If the adhesive has acetone in it, then don't use it. Actone dissolves polystyrene (styrofoam). You can Google this to check it out. I will go out on a limb here and say that most adhesives don't have acetone.

can I use this on a garage door panel?

can I use this on a garage door panel?
Asked by: gr
Yes. R-Tech is manufactured by Insulfoam (as indicated in installation guide online at HomeDepot.com) and they have a garage door kit Home Depot shows online. Insulfoam Garage Door Insulation Kit. Link- https://www.homedepot.com/p/Insulfoam-Garage-Door-Insulation-Kit-320737/205416252. There's a installation video too. Fabricating one out of R-Tech panels might even be more economical but require fastening without the brackets shown in the video.
