Spray Polyurethane Foam (SPUF) has been used successfully with BlazeMaster® pipe and fitting systems for more than 20 years, primarily in the attics and walls of single-family homes that have fire sprinklers. SPUF is an increasingly popular insulation that enhances energy efficiency and improves comfort in the home. When installing SPUF around CPVC pipe and fittings, it’s important to use proper installation techniques to prevent issues related to chemical compatibility and heat generated during application. Here are best practices to ensure your project is a success.
Ensuring chemical compatibility is a top concern for everyone that deals with CPVC sprinkler systems – installers, contractors, designers and building owners. Just as water causes steel pipe to rust, some materials may impact the longevity of CPVC. To ensure a fire protection system works as planned over its full lifespan, BlazeMaster® CPVC must be used in conjunction with compatible ancillary products such as thread sealants, gaskets, lubricants and firestop materials.

BlazeMaster® CPVC is designed for decades of reliable use in fire protection systems around the world. But when issues occur in the field, we want to know exactly what went wrong so we can help our customers prevent problems in the future. It’s a value-added service that also helps our customers know the facts so they can respond to any claims that may arise from a leak or other failure.
BlazeMaster® Fire Protection Systems is the only CPVC fire sprinkler pipe and fitting system with a UL listing for embedding in cast-in-place concrete during new construction.
Chemical compatibility continues to be a topic of significant interest in the fire protection industry. Let’s take a moment to dispel common myths about chemical compatibility.
One of the value-added services that BlazeMaster® CPVC offers is that of failure analysis. We recognize that there are occasional issues in the field. It is in everyone’s best interest that the root cause of the problem be determined to help prevent it from re-occurring.
In the course of installing a CPVC fire sprinkler system in virtually any setting, the potential for the pipe and fittings to come into contact with flexible wire and cable presents itself. While BlazeMaster® CPVC realizes that this may be inevitable, we strongly recommend that fire protection system installers do their best to work with other contractors and review jobsite notification documents from piping manufacturers to avoid such contact if at all possible. If building design requires that the piping and wiring/cabling be installed in tight spaces where contact is unavoidable, consider using a compatible material as a buffer between the two.
Mold and microbial inhibitors are sometimes used in buildings where water damage has been sustained or where general humidity and moisture can result in mold growth. Such products have varying uses. They may be used in new construction or existing buildings as either cleaners to treat construction surfaces or primers for latex paints to remove mold, reduce mold growth or create a microbial barrier for mold prevention.
Lubrizol Advanced Materials’ BlazeMaster® CPVC is the most tested CPVC fire protection material on the market. In fact, we’re so confident in the quality of BlazeMaster Fire Protection Systems, both in physical properties (burst and impact resistance testing) and chemical compatibility, testing is conducted by or overseen by third parties.
For more than 30 years CPVC has been the material of choice for many fire protection systems worldwide, with advantages over steel such as lower initial cost, ease and safety of installation, and a lower cost of ownership that includes better flow rates and reduced maintenance.
