TopBox - The Future of
Roof Entry Solutions
Bespoke Roof Entry Kiosks for Services Penetrations
TopBox is a purpose-built roof entry kiosk system designed to provide a controlled, weatherproof route for ducting, pipework, and electrical services into commercial and industrial buildings.
Factory-built and fully bespoke, each TopBox is engineered around your project requirements, integrating electrical containment, weatherproof pipe entry, and service coordination into a single, high-performance enclosure.
Why Roof Entry Matters
In modern industrial and commercial construction, roof entry enclosures are a critical, but often underestimated - requirement.
Whether it’s ductwork, pipework, or cable entry systems, the way services pass through the building envelope has a direct impact on:
-
Safety and compliance
-
Weatherproofing and long-term durability
-
Thermal performance
-
Installation quality and coordination
Uncontrolled or poorly detailed roof penetrations can lead to leaks, thermal bridging, and costly remedial work.
TopBox solves this by turning roof entry into a controlled, engineered system, not an afterthought.
Designed Around Your Services
Every TopBox unit is configured to suit the exact services entering the building.
Electrical Containment
Integrated containment systems designed to organise and protect electrical services, ensuring clean routing and long-term reliability.
Weatherproof Pipe Entry
Sealed pipe penetrations engineered to maintain the integrity of the roof envelope and prevent water ingress.
Access Hatches
Built-in access points for safe inspection and maintenance of internal services.
Removable Lid System
Allows easy installation, modification, and future access without disrupting the structure.
Ducting Integration
Designed to accommodate ventilation and mechanical ductwork with weather-sealed connections.
Built-In Performance
TopBox systems are designed to deliver performance from day one:
Compliance Built-In
Engineered solutions that support building regulations and good practice for service penetrations.
Weather Protection
Fully sealed construction protects against water ingress and environmental exposure.
Thermal Performance
Designed to reduce thermal bridging and maintain building envelope efficiency.
Speed & Efficiency
