ABOUT WH MANUFACTURING

Built From the Field. Made for the Building Envelope.

W.H. Manufacturing is a building envelope products company built around real-world experience. Our team brings together more than 75 years of combined work across building envelope consulting, contracting, manufacturer representation, field troubleshooting, specification support, and project delivery. That experience shaped a clear point of view: building products should be informed by the realities of the field, not just the language of a data sheet. 

W.H. Manufacturing is a modern manufacturer focused on the systems that protect the building enclosure and keep structures performing over time. Our product categories include roof membrane systems, waterproofing systems, industrial coatings, roof restoration systems, sealant systems, primers, and joint systems. 

We serve building owners, property managers, architects, specifiers, and commercial contractors who need more than a catalog and an order desk. They need products they can trust, documentation they can use, and technical support that reflects how projects actually get built. 

Our company was built by professionals who have spent their careers close to the work; reviewing assemblies, solving failures, supporting installations, helping teams make defensible product decisions, and seeing firsthand what happens when materials perform well and when they do not.

OUR STORY

The W.H. Manufacturing name has historic roots in Idaho. This is important to us because it reflects a set of values that still matter: practicality, accountability, technical know-how, and pride in making products meant to perform in the real world. 

Today’s W.H. Manufacturing is a modern company built for today’s construction market. But its philosophy comes from something older and more durable. It comes from experience earned in the field. 

Our principal consultants and contractors have spent decades working in and around the building envelope industry — specifying systems, supporting contractors, evaluating failures, reviewing details, solving waterproofing problems, and navigating the demands of real projects under real constraints. Over time, that experience made one thing clear: too many products are sold by people too far removed from the places where those products succeed or fail. 

W.H. Manufacturing was created to close that gap. 

We built this company around the idea that building envelope products should be selected, developed, and supported by people who understand substrates, sequencing, weather exposure, detailing, submittals, project schedules, installation conditions, and long-term performance. In other words, by people who understand what is at stake once the product reaches the jobsite. 

That is the standard we bring to every system we offer.

WHO WE SERVE

W.H. Manufacturing supports building envelope projects across the United States. Our products and support model are built for the stakeholders who carry responsibility for performance, cost, and long-term building durability

Building Owners & Property Managers

For owners and managers, the building envelope is not theoretical. It is risk, capital planning, tenant disruption, maintenance exposure, and asset protection. We help provide systems and support that stand up to scrutiny and support long-term decision-making.

Architects & Specifiers

Design professionals need products they can specify with confidence. We support that process with practical documentation, defensible technical positioning, and an understanding of how systems need to be reviewed, coordinated, and applied in the field.

Commercial Contractors

Contractors need responsive manufacturers, clear submittal support, and people who understand schedule pressure, sequencing, labor realities, and installation conditions. That is the lens we bring to contractor support

WHAT WE BELIEVE

We believe the best building envelope products come from people who understand the consequences of failure. 

We believe technical support should be clear, timely, and rooted in actual project conditions. 

We believe service matters just as much as chemistry. 

We believe owners, designers, and contractors are better served when the manufacturer understands how systems are specified, detailed, installed, and maintained. 

And we believe the industry still has room for companies built on straightforward principles: know the work, support the work, and stand behind what you make

BUILT FOR REAL-WORLD PERFORMANCE

W.H. Manufacturing is a company built on long experience. We respect the heritage reflected in the name, but our credibility comes from the work itself — from decades spent in the field, solving problems, supporting teams, and learning what building envelope performance really requires. 

That experience now informs everything we do: the systems we offer, the support we provide, and the standard we hold ourselves to. 

W.H. Manufacturing delivers building envelope products with field-tested judgment, practical support, and a clear understanding of what it takes to make systems work where it matters most: on the buildin
