Frequently Asked Questions
Can a building wrap be installed upside down or with the print facing the wall?
For flat building wraps, installation direction has minimal impact on fabric performance. That said, consistent installation confirms you've followed guidelines for a proper water-resistive barrier. Always install in a shingling fashion and check local codes for overlap requirements.
Note: RainDrop® building wrap must be installed with drainage channels vertical or at a slight angle. Horizontal channels will not drain effectively.
Does fanfold insulation provide meaningful R-Value?
Fanfold's primary purpose is to level walls so new siding installs straight. It adds supplemental R-Value depending on thickness a useful secondary benefit, but not its primary function.
What is the R-Value of Kingspan vacuum insulation panels?
Kingspan OPTIM-R vacuum insulation panels have a design R-value of R-28 — up to five times better than commonly used insulation materials at the same thickness.
Why choose vacuum insulation panels (VIPs) over standard insulation?
VIPs deliver the thinnest possible insulation solution without sacrificing performance — up to five times better than conventional materials. Ideal for retrofits, shallow walls, or any build where space is at a premium.
What is KoolDuct made of?
KoolDuct panels feature a rigid closed-cell, non-fibrous phenolic insulation core faced on both sides with a 25-micron (1 mil) aluminum foil with low vapor permeability, reinforced with a 5 mm glass scrim.
