CertainTeed leads gypsum board industry in environmental claim validations

CertainTeedCertainTeed is the first manufacturer to complete the UL Environmental Claim Validation (ECV) process for its full line of gypsum products. Specifically, UL Environment provided third-party verification for environmental claims including Recycled Content, Regional Materials and Mold Resistance. Additionally, the company secured Permanent Formaldehyde Absorption Capacity validation for its industry-only AirRenew®, which features VOC-scavenging technology that helps improve indoor air quality. The independent, third-party validation process involved rigorous audits conducted at 13 manufacturing facilities across the U.S. and Canada.

CertainTeed gypsum building materials are now listed in applicable categories on UL Environment’s Sustainable Products Database. The online tool allows users to identify sustainable products by product category, company name, product name or evaluation type. The validation process has been completed at all of CertainTeed Gypsum’s manufacturing facilities.

Roof board’s greater flexural strength and pull-through resistance improves job site efficiency

georgia-paciific-gypsumGeorgia-Pacific Gypsum’s recently enhanced DensDeck Prime Roof Board has demonstrated – in third-party tests-significant attributes that boost job site efficiency. DensDeck Prime 1/4-in. fiberglass mat gypsum cover boards demonstrated 2.5 times greater flexural strength, per ASTM C473 test methodology, compared to competitive 1/4-in. gypsum fiber boards. The tests were conducted by PRI, Construction Materials Technologies, earlier this year.

For contractors using DensDeck Prime, the advantage of flexural strength (the ability of a material to withstand bending loads) is that it boosts efficiency on the job site. Additionally, 1/4-in. DensDeck Prime roof board demonstrate 22% more pull-through resistance than 1/4-in. gypsum fiber boards in the fastener system* tested, and are included in more roofing assemblies with RoofNav approvals for wind uplift performance as a cover board than competitive gypsum fiberboard.

Specific attributes include ease in handling, easy scoring and snapping with no special tools required, which means less breakage and waste — all of which can lead to significant time and potential money savings.

The overall durability and performance of DensDeck Prime-demonstrated in its fire resistance, strength, pull-through resistance, dimensional stability and mold resistance– provides a number of other advantages for contractors. For instance, in adhered, single-ply membrane testing, enhanced DensDeck Prime demonstrated an average of 24 percent better bond strength than the original product, when using solvent-based adhesives. (The average is based on 60 sq. ft./gal. coverage rates.) With adhesives applied more smoothly and consistently, contractors gain potential cost savings on the amount of adhesive used and the labor needed to apply it. Also, the mat edge wrap is on the underside of the board, allowing for smoother application of adhesive and a more aesthetically appealing appearance once the membrane is laid down.

Even more important to roofing contractors is that DensDeck Prime is the first and only fiberglass-mat gypsum roof board with a 90-day parapet warranty for exposure. The parapet application can be left uncovered, while the horizontal application of product is being completed.

National Gypsum introduces four CE classes

National Gypsum Continuing EducationNational Gypsum has recently released four new online continuing education courses for the architectural community. Course topics include finishing gypsum and designing for high STC ratings, abuse and impact resistant gypsum and high-performance gypsum products.

The courses include:

  • Abuse and Impact Resistant Gypsum: Stronger and Safer Walls. This course reviews the ASTM C 1629 test standard for abuse and impact resistant gypsum and uses this data to distinguish between abuse resistant and impact resistant gypsum board. Learn how to specify the appropriate gypsum board when a project requires abuse or impact resistant properties.
  • Acoustically Enhanced Gypsum Board: Designed for High STC Wall Assemblies. This course covers key acoustical terminology and third party recommendations for Sound Transmission Class-rated walls. Learn  how acoustically enhanced gypsum compares with existing solutions for achieving higher STC ratings and decreasing sound transmission while increasing valuable square footage.
  • High-Performance Gypsum: Protect Against Mold, Moisture and Exposure. This course focuses on the superior performance characteristics of gypsum products manufactured with fiberglass facing, which replaces the paper facing typically used on gypsum board. In addition, participants will learn about the basic applications, attributes, advantages and limitations of each of the four common product types.
  • Finishing Gypsum Board: Appearance and Indoor Air Quality. Understand trade terminology and applicable standards for specifying the final level of finish for gypsum board. In addition, this course reviews industry-accepted practices for maintaining Indoor Air Quality (IAQ) during construction and after occupancy and examines how finishing practices and products impact indoor environmental quality.

All of the courses are approved by the American Institute of Architects (AIA) and offer one health, safety, and welfare (HSW) learning unit. Each completed program will earn the participant one credit. To learn more or to register for the courses hosted by Ron Blank & Associates, visit http://www.nationalgypsum.com/ng/con-edu/.
