VAULT® Products
The VAULT® offers exceptional protection for your roof and wall penetrations, while meeting mandatory code requirements for air permeance/air leakage and solar reflectance. Our advanced engineering solutions and compliance with industry standards make the VAULT® the preferred choice for architects, engineers, and building owners wanting to ensure maximum protection and durability for their roof and wall penetrations.

AW VAULT®
The AW VAULT® provides a secure, multi-penetrant pathway to the roof that's insured and warrantied for 20 years. This three-piece assembly features a heavy gauge, all-aluminum, powder-coated construction. It includes flanged curb that works together with our RPH Exit Seals for a weather-tight fit around pipes, cables, ductwork, and other penetrants of various sizes.

AWI VAULT®
The AWI VAULT® is an AW VAULT® that includes an insulation curb extension (ICE). In addition to the specifications listed in the AW VAULT®, the AWI VAULT® allows for insulation to be installed on-site to further enhance thermal performance along the curb. This VAULT series comes with an air/wind-rated assembly.

Wall VAULT®
The WALL VAULT® provides a single pathway for multiple penetrations through a parapet or exterior wall. It is constructed using heavy-gauge powder-coated welded aluminum and stainless steel hardware, and is paired with our weather-tight exit seals. Alt-hough the WALL VAULT® is built with the same high-quality mate-rials as our AW VAULT®, it has not been third-party tested as a standalone product.

RPH Exit Seals™
RPH Exit Seals™
The hidden advantage behind every VAULT® solution.
RPH Exit Seals™ are a critical part of what makes VAULT® products perform at the highest level. While not sold separately, these seals are fully integrated into every VAULT® system. They provide watertight, airtight, durable, and flexible protection for roof penetrations and are backed by a 20-year warranty.
Why they matter:
- Watertight and airtight: Provides lasting protection against water and air infiltration in all conditions.
- Lightweight and easy to install: Simplifies field installation and reduces labor demands.
- Designed to handle movement: The flexible gasket adapts to temperature changes, vibration, and structural shifts without cracking or losing its seal.
- Performance range: Reliable from -65°F (intermittent -100°F) up to +450°F (intermittent +500°F).
- Custom sizes available: Accommodates large-diameter pipes or specialized penetrants; can be configured to fit any size or shape.

FAQs
The Standard VAULT® is tested and meets the requirements of the 2023 Florida Building Code. The Standard VAULTs were tested to HVHZ and Large Missile Impact requirements in accordance with TAS 201, TAS 202, and TAS 203. The Standard VAULTs were tested to a design pressure of +/- PSF.
The Standard VAULT® was created to change the paradigm in roof penetrations by providing a single, secure pathway for multiple penetrations through the roof which eliminates leaks and meets the building code requirements for air permeance and missile impact (e.g., ICC, Miami-Dade/Florida).
The Standard VAULT® was created as a superior alternate solution to pitch pans. As seen time and again in the industry, the pitch pans will fail because the sealant can dry out and shrink, causing leaks. Putting a rubber boot or diverter on it doesn’t solve the problem in the long term, and can even create additional issues. The VAULT®, however, provides a single pathway for multiple penetrations and will replace vertical penetrations with a tightly sealed horizontal penetration.
All penetrations should be supported no more than 12” from exiting the housing, and also, below the roof level as near as possible to the bottom of the roof opening. FAILURE TO DO SO WILL VOID THE WARRANTY.
We add R4 insulation to provide a minimal level of protection; however a vapor barrier and additional insulation must be added to meet local requirements.
The housing has a 3″ built-in counterflashing. The curb to housing connection acts as a termination for the roof material.
No. The lid and curb should NEVER have a penetration. Doing so will compromise the integrity of the VAULT® and void the warranty. In addition, the lid and the curb should never be punctured. Only use the pre-drilled holes for the fasteners.
