“It is strongly recommended that pre-hung, pre-finished fire doors (i.e door sets) are specified whenever possible as this reduces the amount of site work necessary and allows normal factory quality control procedures to be applied to the finishing operations”
BS8214: 1990 “Code of Practice for Fire Door Assemblies with Non-metallic Leaves” – extract.
Youngs Doors doorsets are an engineered set of components intended to function as a complete and fully-finished assembly. All components are pre-assembled and matched at our factory for straightforward installation and re-assembly at site.
Traditionally, a door and frame installation comprises a similar set of elements sourced from disparate suppliers, brought together, assembled and finished on-site by a number of individuals of differing skill levels; a set of factors that may bring unseen errors by an array of suppliers/installers focusing only on their individual element.
This means that a traditionally sourced door-set assembly may not replicate the test conditions under which it was certified – crucial where a life-safety function is present.
Quite apart from the quality of installation, is the added value of the factory engineered door-set. The reduction in site hours and resultant cost savings are well documented.
