===Papers and membranes===
{{unsourced section|date=December 2024}}
Building papers and membranes are used for many reasons in construction. One of the oldest building papers is [[red rosin paper]] which was known to be in use before 1850 and was used as an underlayment in exterior walls, roofs, and floors and for protecting a jobsite during construction. [[Tar paper]] was invented late in the 19th century and was used for similar purposes as rosin paper and for [[built-up roof|gravel roofs]]. Tar paper has largely fallen out of use supplanted by asphalt [[felt paper]]. Felt paper has been supplanted in some uses by synthetic underlayments, particularly in roofing by synthetic underlayments and siding by [[housewrap]]s.

There are a wide variety of [[damp proofing]] and [[waterproofing]] membranes used for roofing, [[basement waterproofing]], and [[geomembrane]]s.
