CPVC vs Steel Fire Sprinkler Systems in Combustible and Concealed Spaces
Designers, specifiers, installers, and building owners must understand the application of BlazeMaster CPVC in combustible concealed spaces
- Combustible concealed spaces not requiring sprinkler protection by NFPA standards 13R and 13D may be piped using BlazeMaster CPVC.
- Combustible concealed spaces requiring sprinklers – such as attics (open wood truss construction) or crawl spaces – may be piped using BlazeMaster CPVC provided special UL-listed sprinkler heads from Tyco, Viking, Reliable or Globe are utilized. The installation must be installed per the sprinkler head manufacturer’s listing and installation instructions.
This is significant because while steel pipe is allowed in all types of applications, the advantages of CPVC over steel such as easier, faster installation and maintenance plus lower upfront costs make CPVC the hands-down choice whenever it can be used.
CPVC’s Advantage Over Steel
BlazeMaster CPVC can save time and money in both retrofit and new construction in areas that would not normally be considered “living space.”
It can be run through combustible concealed spaces that don’t require sprinklers, such as small closets or bathrooms, to attic areas that may then be sprinklered using approved sprinkler heads.
In an attic installation that must be sprinklered, attic sprinklers specifically listed for use with CPVC must be used at all times per NFPA 13. BlazeMaster CPVC pipe must be protected with 6” (152 mm) of non-combustible insulation on top of the pipe in this configuration.
Isn’t It Easier to Just Spec Steel?
The debate over Steel vs CPVC Fire Sprinkler System often zeroes in on ease of installation and cost. Here are compelling reasons to choose CPVC in combustible concealed spaces:
Lower Initial Cost: Steel piping is invariably more expensive than CPVC due to its material costs and the volatile nature of steel pricing, which complicates budgeting.
Faster, Easier Installation: Steel's weight requires special handling equipment and typically multiple installers, especially in constrained spaces where manoeuvrability is challenging. Steel installations need torches and threading machines for system fabrication and assembly. On the contrary, BlazeMaster CPVC is lightweight and can often be installed single-handedly using simple cutting tools and solvent cement, translating to significant savings on installation.
Long-term Maintenance Savings: Steel pipes are prone to corrosion and scaling, particularly under harsh or hard water conditions, potentially leading to leaks, system failures, and impaired functionality. CPVC, by contrast, maintains its condition over time, ensuring the sprinkler system remains effective in fulfilling its critical roles of protecting lives and property.
