Take a detailed look at our TopBox GRP roof entry system. This walkthrough showcases the internal design, robust construction, and weatherproof features that make it a reliable solution for industrial and commercial sites.

When a TopBox Roof Entry System is installed on a building, the enclosure itself is only part of the solution. The real performance comes together once all pipework, equipment and penetrations are fitted - and that’s when Hill Grwp applies one of the most important finishing steps: our engineered weatherproof pipe entry insulation seal. 

Across this multi-site project area, our client required a series of reliable and compliant rooftop entry system to safely house critical equipment. Every location was different - varying roof layouts, equipment footprints, and operational needs - which made TopBox the ideal solution.  TopBox is our fully customisable GRP roof entry system, developed to give facilities teams the flexibility, safety, and durability they need… without disruption to ongoing operations. 

Our TopBox GRP roof entry system now installed at a UK Police firing range, providing secure, weatherproof access while maintaining a clean and low-profile finish.
