Frequently Asked Questions

Can building wrap be installed in any orientation?
No, drainage channels must be installed vertically or slightly angled from vertical to function properly. Horizontal installation reduces drainage performance.

Should fanfold or building wrap be installed first?
Installation order depends on the project. For full replacements, install fanfold first, then wrap. For existing windows, install wrap first, then fanfold.

Can house wraps be used under any exterior facade?
House wraps are suitable for most cladding systems and are required by building codes as water-resistive barriers, though some systems may require multiple layers.

Why use a house wrap?
House wraps improve thermal performance by reducing air leakage and protect wall systems from moisture, helping prevent material degradation.

Can fanfold siding underlayment replace building wrap?
Yes, when compliant with ICC-ES AC71 and installed per guidelines, it can serve as a water-resistive barrier without additional wrap.
