Keep the door slim
Add thermal resistance within restricted leaf and frame cavities.
Elevator and fire-rated doors
Fire protection that fits inside the door.
Elevator landing doors must balance fire resistance with leaf depth and moving mass. Siltherm Panel FP is configured for these restricted assemblies.
Limit added mass
Use a lightweight microporous panel in weight-sensitive moving assemblies.
Match the tested assembly
Keep panel grade, joints, fixings and door construction connected to the applicable evidence.
Door positions
Protection across the leaf, frame and critical interfaces.
The insulation is selected as part of the rated door construction.
Elevator door leaves
Thin panels fit into limited leaf cavities while supporting a lightweight door construction.
Public-building and service doors
Configured panels support defined fire-rated door assemblies and protected access points.
Frames, joints and hardware zones
Panel layout, seams, fixings and clearances are coordinated with the applicable door construction and test evidence.
Door-leaf integration
Thin protection, built into the door leaf.
Panel FP is configured around the available cavity, hardware and fixing zones.
Skin and internal cavity
Available depth and hardware layout define the insulation space.
Siltherm Panel FP
Custom dimensions reduce joints and added weight inside the leaf.
Frame, joints and fixings
Final fire performance is assessed on the complete tested construction.
Door-leaf cutaway
See where the insulation fits.
Panel FP sits inside the door leaf, clear of the track and operating hardware.
01Upper track
Operating hardware remains accessible above the leaf.
02Steel door skin
The outer leaf encloses the insulation and internal frame.
03Internal frame
Panel dimensions follow hardware and fixing zones.
04Siltherm Panel FP
A thin microporous panel fits within the available cavity.
01Upper track
Operating hardware remains accessible above the leaf.
02Steel door skin
The outer leaf encloses the insulation and internal frame.
03Internal frame
Panel dimensions follow hardware and fixing zones.
04Siltherm Panel FP
A thin microporous panel fits within the available cavity.
Matched Siltherm formats
Panel configuration and assembly evidence considered together.
Siltherm configures panel dimensions and coverings for the intended door construction.
Designed around the assembly
Door geometry and rating requirements shape the panel configuration.
Share the door construction and rating target so Siltherm can identify the relevant Panel FP route.
