Fire Door Frame Adjuster & Detachable Architrave System
1. Introductory Statement
This page provides a factual technical overview of the Proudman Fire Door Frame Adjuster and Detachable Architrave System. The information is intended for fire engineers, certification bodies, manufacturers, building control professionals, and other technical reviewers.
2. System Overview
System Overview
- Purpose of the system
- Addresses installation, inspection, and long-term maintenance
- Designed for timber fire doorsets
- Focus on non-destructive access and adjustability where required
3. Fire Door Frame Adjuster
Fire Door Frame Adjuster
- Mechanical function (frame alignment within wall opening)
- Eliminates traditional packers and rigid fixing constraints
- Allows adjustment during installation and at later stages
- Access without removal of finishes or frame damage
- Intended to reduce labour time and disruption
4. Detachable Architrave System
Detachable Architrave System
- Provides access to the frame-to-wall junction
- Allows removal and refitting without tools, noise, dust, or damage
- Enables inspection of fire-stopping materials
- Dry-fit, reusable system
- Suitable for occupied or sensitive environments
5. Materials & Construction
Materials and Construction
- Frame adjuster: 304 stainless steel mechanical components
- Intumescent lid: accepts standard 15 mm or 20 mm intumescent strips (fire only or fire & smoke)
- Plastic components: flame-retardant, construction-grade polymers, CE marked
- Fixing compatibility: masonry fixings, timber screws, standard installation methods
6. Installation Context
Installation Context
- Designed for timber fire doorsets
- Suitable for new installation or retrofit
- Fixing positions aligned with conventional fire door frame fixing practice
- Compatible with masonry and stud wall substrates
- Adjustment carried out using standard hand tools
7. Testing & Compliance Pathway
Testing and Compliance Considerations
- Detachable architrave considered a decorative component, subject to manufacturer certification scope
- Frame adjuster intended for inclusion in EN 1634-1 fire doorset testing
- Component-level testing planned (mechanical, heat exposure, pull-through)
- Doorset testing required to confirm integration
- Collaboration with manufacturers and testing bodies welcomed
8. Lifecycle Maintenance Rationale
Lifecycle Maintenance Considerations
- Supports repeat inspection over the life of the doorset
- Allows maintenance without destruction or redecoration
- Minimises disruption, waste, and downtime
- Suitable for buildings requiring frequent inspection cycles
