BUTLER DOORS
Performance door set manufacturers to the construction industry

Vision Panels

The illustration opposite shows common openings that provide up to 60 minute fire rating. These can be found in a number of industry standard documents and available in many other manufacturer's offers, however due to the bespoke nature of our products and the CNC routering capabilities available to us we offer specifiers the freedom to design doors that are unique or to recreate existing designs in a specific building.

A key feature to any door, for both aesthetics and industry standards, is the ability to integrate vision panels.   

Glazing has a major impact on the performance of the sets, the appropriate gasket, glass, glazing method and bead configurations need to be allowed for depending on the performance requirements, all of which we accommodate as standard.


The glass retention systems available include hardwood bolection and flush beads all as detailed below. Specialised systems and finished are also available for alternative situations.
