Buildings such as data centers, distribution facilities, big box retailers, schools and hospitals contain precious lives and expensive equipment. The roof system is essential to protecting these assets from everyday service traffic and wind pressures to extreme weather events such as hail, hurricanes and tornadoes. Hard roof coverboards offer numerous benefits that enhance the durability, safety and performance of the entire roof assembly. In this episode, Chris Whitmire, director of product marketing for National Gypsum, talks to Warren Barber, senior manager gypsum & specialty systems/DEXcell, about the science behind the benefits of using DEXcell Roof Boards, manufactured by Gold Bond Building Products, LLC and PermaBASE Building Products, LLC, which are affiliates of National Gypsum Company. Listeners will learn: What are hard coverboards and their essential role in commercial roofing systems How hard coverboards provide a smooth, flat surface for the membrane and protect insulation from foot and equipment traffic How hard coverboards improve the roof's performance ratings against fire, wind,and hail The role of hard coverboards in improving thermal performance Want to know more?

Understand these critical life safety systems to avoid costly installation errors The gypsum board shaftwall system was first implemented in 1973 to accommodate increasingly tall buildings and was first used in the World Trade Center. Shaftwall assemblies enclose all manner of shafts: elevators, stairs, trash chutes and ventilation ducts to name a few. They are designed to prevent fire from spreading between floors via these shafts and to protect stairways as an escape route for building occupants during fires. Gypsum board is lighter than traditional shaft enclosure materials, such as masonry, and provides efficient and economical installation. In this episode, Sam Halverson, construction services manager with the 1-800-NATIONAL Construction Services team, talks with host Chris Whitmire about why it's important to correctly design and install shaftwall enclosures. Listeners will learn:

• The purpose and history of shaft enclosures
• The difference between 1-hour and 2-hour UL fire-rated shaftwall systems
• A breakdown of materials used to construct a shaftwall and how it is constructed
• Gold Bond Building Products gypsum boards and shaftliner panels recommended for use in shaft enclosures
• How a shaftwall is designed to be fire-rated from both sides
• Tips for including elevator guide rail support posts in a shaftwall
• When the building code requires shaft enclosures to have impact resistance
• How shaftwall assemblies can be used as ceiling assemblies
• Best practices for ensuring fire-resistance continuity in shaftwall corners

Noise pollution can have harmful effects on human health, ranging from simple annoyance and distraction to increased blood pressure and stress.* Effectively reducing the distance sound can travel is critical to creating pleasant spaces where people live, work and play. The first step toward designing quality acoustical assemblies is understanding the differences between Sound Transmission Class (STC), Impact Insulation Class (IIC), Ceiling Attenuation Class (CAC) and Outdoor-Indoor Transmission Class (OITC).

Listeners will learn:

• Why noise reduction is important
• What the four acoustic ratings — STC, IIC, CAC and OITC — measure and how they are tested
• Real-world examples of noise challenges gypsum board acoustical assemblies solve
• The role National Gypsum's Fire & Sound Assembly Selector can play in selecting assemblies that meet both acoustical and fire ratings

Specifying continuous insulation has become common as communities adopt more current versions of the International Energy Conservation Code. At the same time, current exterior design trends for commercial, multifamily and mixed-use retail/residential favor mixed-material facades which break up storefronts and lend a scaled down neighborhood feel. Combining veneers — thin brick, thin stone, stucco and tile, to name a few — empowers architects and builders to create unique exteriors.

In this episode, Eddie Neel, market manager for PermaBASE® Building Products, talks to Chris Whitmire, director of product marketing at National Gypsum Company, about how PermaBASE CI® Insulated Cement Board provides a simple solution to both challenges.

Listeners will learn:

• What continuous insulation is and how it can help meet energy code requirements
• How PermaBASE CI is constructed and how it simplifies the installation of mixed material exteriors that also meet energy code requirements
• The concept of "R-values" as it pertains to buildings and materials
• Which adhered veneers work with PermaBASE CI and how they are installed
• Recommendations for horizontal and vertical transitions between different adhered veneers
• When to install control joints on adhered veneers installed on PermaBASE CI
