The word "tarpapers" is spelled with two syllables, /tɑr/ and /peɪpərz/. The first syllable, "tar," refers to a viscous substance used for waterproofing, while the second syllable, "papers," refers to thin sheets used for writing or printing. Together, "tarpapers" typically refers to a type of building material made from paper or felt and coated with tar for added durability and waterproofing. While the spelling of "tarpapers" may seem unusual, it accurately reflects the pronunciation of the word.
Tarpapers, also known as roofing felts or tar felts, are a type of building material used primarily in construction and roofing projects. These papers are typically made from a heavy-duty, fibrous material, such as cellulose or fiberglass, that is impregnated or coated with tar or bitumen.
The main function of tarpapers is to provide a protective barrier against water and weather elements. They are commonly used as an underlayment for roofs, serving as a waterproof membrane that prevents moisture from penetrating into the building structure. Tarpapers also offer some level of insulation and help to control condensation within the roofing system.
One common type of tarpapers is known as asphalt-saturated organic felt, which is made from a combination of cellulose fibers and asphalt. Another variation is fiberglass-based tarpaper, where a layer of fiberglass is sandwiched between sheets of waterproofing material.
Tarpapers are typically available in rolls of various sizes and thicknesses, allowing for easy installation across different roof types and structures. During installation, the sheets are usually laid in overlapping layers to create a continuous barrier that directs water away from the roof and protects the underlying structure. The edges of the tarpapers are often sealed with adhesive or heat for additional protection against leaks.
Overall, tarpapers play a crucial role in providing an extra layer of waterproofing and protection to roofs, helping to increase their durability and longevity.
The word "tarpapers" does not have a specific etymology because it is a compound word formed by combining two separate words: "tar" and "papers". However, the etymology of these two individual words can be examined.
The word "tar" originates from the Old English word "teru" and can be traced back to the Proto-Germanic word "tarwo". It has been used to refer to a dark, viscous substance derived from various organic materials, often used as a protective coating or adhesive.
The word "papers" comes from the Old French word "papier" and can be traced back to the Latin word "papyrus". Papyrus was a material used in ancient times for writing and creating documents, and the word evolved to refer to various forms of paper.
When combined, "tarpapers" refers to a type of waterproof material made by saturating paper with tar or bitumen.
