Roof Penetration Housings
RPH is an engineering-driven manufacturer of roof and wall penetration enclosures and ICC 500-compliant safe room products. We specialize in protecting the building envelope through tested, code-aligned solutions designed to manage air, water, thermal performance, and structural movement. In addition to standard product lines, our in-house engineering team develops project-specific solutions to meet exact performance and specification requirements.
Originally founded as a code-focused penetration manufacturer, RPH has grown into a technical resource for architects, engineers, and contractors addressing complex envelope conditions. By collaborating early in the design process, we deliver engineered systems that resolve constructability challenges while maintaining long-term performance.
The VAULT® series is third-party tested to verify compliance with applicable air permeance, insulation, and energy code requirements, including IECC criteria. The CYCLONE® series is tested to meet ICC 500 and FEMA P-361 requirements for plumbing, mechanical, and electrical penetrations within safe rooms and storm shelters.
RPH backs its products with a 20-year insured warranty on VAULT® assemblies and RPH Exit Seals™, and a 3-year insured warranty on CYCLONE® products. Our commitment to code compliance, durability, and engineered performance makes RPH a trusted partner for penetration protection across projects of any scale or complexity.
