Tendencias de construcción: cómo elegir OSB resistente al fuego para la envolvente de terrazas Texas Donut Construction

El crecimiento de la población en muchas ciudades de Estados Unidos está impulsando el surgimiento de un diseño de edificio diferente dentro de sus áreas urbanas y suburbanas. Esta demanda de edificios de mediana altura de alta densidad da lugar a desafíos y oportunidades para que los arquitectos ejecutan diseños con eficiencia y rendimiento estructural.

Deck wrap projects are one specific design trend, oftentimes referred to as the “Texas Donut.” It comes as developers in the Sunbelt region respond to demands for affordable and secure apartment-style housing offering both walkable streets and nearby parking.

Texas Donut Building Style

The Texas Donut building is an example of wraparound construction style. It's based on a parking structure in the middle and wrapped on the sides by condos and apartments, which allow the parking structure to be hidden from view. This building style is most common in less dense spaces, like suburban areas.

Wraparound or Texas Donut construction brings an entirely different level of challenges versus traditional mid-rise wood-framed construction. Designers must meet code requirements for fire-resistant construction adjacent to the parking structure, while trying to provide a constructible solution.

LP® FlameBlock® OSB Wall Assemblies in Apartments and Residential Occupancies

Finding the proper fire-rated OSB assembly that meets code while working ideally within a Texas Donut can be difficult. 

LP® FlameBlock® Fire-Rated Sheathing combines flame-spread resistance and burn-through resistance in a single versatile OSB panel. There are multiple wall assemblies available to meet your specific requirements, including load bearing and nonbearing type of construction.

"One of the true benefits of LP FlameBlock wall assemblies is that they may reduce the number of sheets on the wall," says Scott Johnson, Construction Services Manager for LP Building Solutions. "If a one-hour wall assembly adjacent to the parking structure is required, the LP FlameBlock V340 assembly requires only one sheet on each side of the stud, which should simplify the erecting of the wall."

Best Practices for Texas Donut Building

The obvious challenge with Texas Donut building designs is that it's essentially two buildings--the parking structure and multifamily living areas--built with minimum fire separation. Both structures are constructed with different materials--the parking is generally concrete while the living areas are wood construction.

It’s critical the walls adjacent to the parking structure have radiant heat resistance on the side of the wall facing the parking structure. These walls are generally either one- or two-hour wall assemblies for wood-framed construction. “It simplifies the process when designers can deem these walls as non-bearing for Type III construction,” says Johnson. Non-bearing walls generally only require one-hour fire-resistant rated wall assemblies.

Johnson explains the walls between the parking garage and residential areas are large scale--easily measuring over 100 feet long. It's easier to frame large-scale walls with one-hour wall assemblies because it allows manageable sections of wall to be put in place and a single sheet solution doesn't have the requirement of overlapping the vertical joints when two panels are on the same side of the wall.

"When you have at least two layers of gypsum on the stud wall, common with a two-hour fire-resistance-rated wall assembly, you are supposed to overlap the vertical panel joints, which is difficult to do when the length of wall is over 100 feet long," says Johnson. "With the V337 assembly, there are methods to allow for a splice that allow you to construct manageable sections of wall that can be lifted into place. For information on methods, contact your LP rep."

If you have a Texas Donut project––or any construction requiring fire-rated assemblies––contact your LP rep. “We will work with you on appropriate assembly options that will help facilitate construction,” says Johnson.
