Products in the The Align Project: Protecting Occupants, Helping Builders
The Align Project demonstration house showcases products and materials that contribute to beauty, efficiency and functionality. Some also help protect occupants in the event of fire.
Products in the The Align Project which help occupants in the event of fire include a PureFlow residential fire sprinkler system from Viega and a fire-resistant building envelope insulated with COMFORTBATT, COMFORTBOARD and AFB mineral fiber products from Rockwool. These products are also easy for builders to work with and facilitate quick construction, saving time and money.
The 13D-rated fire sprinkler system from Viega uses polymer fittings and flexible PEX tubing.
“In contrast to the metal fittings that most of our competitors use, polymer fittings reduce cost, which is a big barrier to entry for residential customers,” says Seth Larson, product manager for Viega LLC.
Because the system uses PEX rather than rigid pipe, installers can mount the sprinklers before running the PEX tubing, saving time and labor. The system also includes a special mounting bracket with “mounting reference designators,” which accommodate different pendant styles and ensure they are installed at the right depth.
What is 13D?
NFPA 13D is an installation standard developed by the National Fire Protection Association (NFPA) for residential fire sprinkler systems for one- and two-family dwellings and manufactured homes. The intent of the standard is “to provide an affordable sprinkler system in homes while maintaining a high level of life safety.”
Exterior and cavity mineral wool insulation from Rockwool will contribute to energy efficiency, acoustics and fire resistance to The Align Project demonstration home.
Mineral wool insulation is naturally non-combustible. With a melting point of 2,150 °F, the material can help contain a fire and keep it from spreading to other rooms. It also has a smoke developed index of 0—the lowest possible, meaning it will not contribute significantly to toxic emissions.
Rockwool products also offer benefits to the builder or installer. The high-density material is dimensionally stable and friction fits into cavities without sagging. This is a plus for modular homes, which are often transported to the site mostly or fully constructed. Rockwool also works directly with modular home builders, streamlining the sales process and ensuring good detailing.
