Reason for Window Film

Located in London, The National Audit Office (NAO) scrutinises public spending for Parliament. Their public audit service helps Parliament hold government accountable, to help improve public services.

As an official governmental office, they recognised the need to have bomb-blast window film installed, to protect staff in the event of a terrorist incident and to protect the integrity of the historical landmark building.

Prism arranged a meeting to determine the correct type of window film that was required. After providing a "best value" quotation, they were awarded the contract.

Prism Solution


Work had to be carried out with minimum disruption and with full appreciation for the confidential government data that was being used throughout the occupied offices. Prism worked nights and weekends, as well as weekdays, to complete the project on-time, using different teams of installers on different shifts.

As well as being a modern office, parts of the building were listed as “Art Deco”, so the outside appearance of the building had to remain as originally-preserved as possible. Once installed, the safety film was invisible, so the outside visual appearance of the building remained unchanged.



Project Outcome


A weekly project game-plan, including periodic meeting updates, ensured both day and night workers were on-track to complete the overall project, to the timescales agreed. Working to this plan, Prism successfully installed the 175 x micron anti-shatter film to all windows across all floors, enabling staff to continue working while we worked in common areas during the day and office areas at night and weekends.

The client was very satisfied with the completed work done, to the original timescale and quality promised. A final walk-around was arranged one week after completion, to correct any outstanding issues and to finalise sign-off for the contract.

Prism staff was congratulated for their politeness, cleanliness, approach to health and safety and their understanding of the work ethics required for working within this prestigious site.
