Intumescent strips and smoke seals questions

Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
How long do seals last?
It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.

Only where the door is specified for smoke control, such as FD30S doors. Many doors on escape routes and flat entrances are specified this way.
