This blog post, originally shared in the Pharos Signal, includes information about parts of Pharos that are no longer available. Please use it for historical reference and for the other useful information it contains.
Wallboards, our newest addition to the Pharos Building Product Library, are now ready for users to explore. The first batch of products focuses on products from three leading manufacturers, Georgia-Pacific,National Gypsum, and Temple-Inland. Over the coming weeks, we will add many more companies and products.
Wallboard is any flat board used to cover walls and partitions. These building materials also are called drywall, gypsum board, or plasterboard.
Drywall is most commonly comprised of a gypsum core, with Kraft paper facings and additives. There are several types of modifications. The most common is Type-X, which is fire-resistant board. Other variations include moisture-resistant (MR, or "green") board, acoustical board, insulating board, and fiberboard, which can include recycled newsprint fibers and perlite filler. Gypsum board is occasionally backed not with paper, but with vinyl or foil.
These are ubiquitous materials. Everyone specifies them. Over 95% of the walls used in the US and Canada are finished with gypsum board. This includes residential, commercial, and institutional buildings.
As this category is unveiled, Pharos users will encounter a surprisingly diverse range of content and scores. We will explain the significances of these variations in the product records and in Signal articles in the coming weeks.
Among the issues:
Pharos' ever-expanding library of building material evaluations now includes five product categories and over 200 products. We will be adding more categories later this month. Thank you for subscribing and supporting our non-profit efforts to shed light on the building material marketplace.
