Engineering precision
Flow regulation, operating pressure windows, and loop spacing are published with the same rigor as product photography—so plan reviewers see numbers, not slogans.
Company heritage
For more than eight decades, Uponor has engineered PEX-a piping, ProPEX expansion fittings, and radiant heating systems trusted by mechanical contractors and design engineers across thirty-plus countries.
Timeline
Uponor begins manufacturing piping components for building water systems, establishing a culture of dimensional stability and field-serviceable connections.
Engel-method cross-linked polyethylene becomes the backbone of potable and hydronic circuits, improving freeze resilience versus rigid metal runs in many assemblies.
Patented cold-expansion fittings create visible, inspectable joints that recover around the fitting body for leak-resistant mechanical bonds.
Manifold systems, zone valves, and pre-insulated pipes expand the portfolio into underfloor heating, cooling, and campus distribution laterals.
Licensed professional engineers provide complimentary design assistance—from radiant layout drawings to hydronic calculations—helping contractors win bids and install with confidence.
Values
Flow regulation, operating pressure windows, and loop spacing are published with the same rigor as product photography—so plan reviewers see numbers, not slogans.
NSF/ANSI 61, NSF/ANSI 14, IAPMO, ICC-ES, and PPI pathways keep potable and hydronic claims third-party verified rather than self-declared.
ProPEX tool training, manifold balancing coaching, and warranty documentation travel with the material so O&M teams inherit a usable system, not a mystery box.
People
Chief Application Engineer — hydronic load modeling and radiant slab assemblies.
Compliance Lead — NSF/IAPMO listing packages and jurisdiction matrices.
Field Training Director — ProPEX technique and manifold commissioning clinics.
District Energy Specialist — pre-insulated laterals and campus plant tie-ins.
Listings
When project teams weigh natural stone radiant overlays against engineered underfloor panels, our published compressive strength and moisture vapor transmission notes keep the debate quantitative. Prefabricated pod risers versus stick-built manifolds, and domestic versus imported specialty fittings, are documented with lead-time and listing implications so sustainability mandates and budget pragmatism can be scored side by side without rewriting the mechanical narrative.
Whether you need radiant layout drawings, ProPEX training, or a full documentation binder, our desk responds with pipe-size-level answers.
