Constructing a home is chaos management. Disparate trades struggle to coordinate ever-changing schedules and budgets. The uncertainties can be endless, and the entire process can feel overwhelming and intimidating. Enter: prefabricated manufacturing companies. Prefab manufacturing’s main mission is to streamline and expedite this daunting process by localizing most of the construction within a controlled facility managed by a single team.
Prefab manufacturers turn high performance construction into a streamlined factory operation - protected from the elements throughout the year. This process can deliver panelized or modular packages (in our case, primarily panelized) to job sites where they’re assembled in a few days - creating consistently airtight, high performance homes. Not only does panelized building simplify the entire process, but it also significantly speeds up the construction timeline. 475.Supply is proud to work with more than 20 prefab manufacturers across North America who trust 475.Supply and the Pro Clima system, and have chosen to use our products in their operations.
Among these prefab manufacturers, you will see a series of products that are relied on consistently for waterproofing, airsealing, and vapor control. Many of these companies' wall systems that utilize 475.Supply’s Smart Enclosure details (especially the Double-Stud and I-Joist editions) to develop assemblies that are optimized for their work. Although there are many variations found, all of these options are well suited for Passive House levels of performance. Here’s a breakdown of the prefab industry’s go-to material selections:
| PREFAB INDUSTRY'S FAVORITE MATERIALS | |
|---|---|
 TESCON VANA intro video
|
Solid acrylic tape for membrane seams and misc. connections that is airtight, watertight, and vapor permeable. Prefab companies love the versatility, being able to use one tape for nearly everything, and the quality of VANA’s tough & durable fleece backing. |
 SOLITEX MENTO 3000 intro video
|
As with all membranes in the SOLITEX family, it's an airtight, monolithic, actively vapor-open WRB / roof underlayment membrane. SOLITEX MENTO 3000 provides the greatest water resistance, durability, and has 4 months of UV resistance on roof and 6 months of walls climate zone 4+) - which makes it the first choice for prefab and panelized construction that needs to be able to take a beating during transportation. |
 SOLITEX MENTO PLUS intro video
|
Airtight, monolithic, actively vapor-open and ruggedly durable, 4-ply weather resistive barrier, with a tear-resistant reinforcement mesh suitable for dense-packing insulation without the need for exterior sheathing. Great for blowing cellulose through the exterior of prefab panels in the shop. |
 ADHERO 3000 intro video
|
A self-adhering, monolithic, vapor permeable membrane, and a durable WRB / roof underlayment. Prefab companies love the UV resistance of the membrane and the ability to self-seal around point penetrations (screws/nails). |
 INTELLO PLUS intro video
|
This interior air barrier is loved by Prefabbers for all the same reasons as the rest of the industry. More than simply an air barrier, it’s is a one-of-a-kind smart vapor-variable membrane, and dense-pack insulation reinforcement. It protects against moisture accumulation in highly insulated walls and roofs in all North American climates and is the most airtight rated system by Passive House Institute (0.0m3/(m2*hr) |
 INTELLO X intro video
|
Take all the aspects of INTELLO PLUS and include an extra robust fleece and you get INTELLO X. It offers all the value of INTELLO Plus, but in the form of a heavy-duty, commercial grade membrane suitable for up to 2 months of weather and UV exposure. |
“We got here a week ago, and now the panels are in. We used the INTELLO membrane on the ceiling, a bunch of SOLITEX MENTO on the exterior, and VANA tape everywhere. We’ve been really, really happy to be partnered with 475 for a full decade now. Loving all the support, loving all the great products, and can’t wait to do more!” – Rane Wardwell, Collective Carpentry
