Norseal NOR905 Graphite Radius Hinge Pad is a pre-cut intumescent pad designed for installation behind a compatible radius-corner hinge blade within a fire-resisting timber doorset.
The pad creates a thin protective layer between the metal hinge blade and the timber door leaf or frame. Under fire conditions, the graphite intumescent material reacts within the hinge recess, helping protect the surrounding timber and support the performance of the complete doorset.
Each pad is supplied in one fixed configuration:
Fitting a hinge requires recesses to be formed in the door leaf and frame. These recesses remove part of the original timber construction and introduce metal components that can transfer heat into the surrounding material.
Where required by the hinge or doorset evidence, the NOR905 pad is positioned directly behind the hinge blade to help:
The NOR905 uses a slim 0.5mm graphite intumescent material. This provides concealed protection without adding the greater thickness associated with some alternative hinge-pad products.
The 0.5mm thickness must only be used where it is permitted by the supporting hinge and doorset evidence. A thicker pad is not automatically better, and a thinner pad must not be substituted where the tested arrangement requires another specification.
The rounded corners are designed to correspond with a compatible radius-corner hinge blade.
Before ordering, compare the pad with:
Do not use the radius pad behind a square-corner hinge where the shape would leave part of the required protection area uncovered.
The self-adhesive backing helps hold the pad accurately within the hinge recess while the hinge blade is positioned and mechanically secured.
The adhesive is an installation aid only. It does not provide the structural fixing for the hinge and does not replace the specified hinge screws.
The receiving surface should be clean, dry, flat and free from dust, grease and loose timber fibres.
Each ordered item contains one hinge pad.
The required quantity depends on the tested or assessed doorset arrangement. Protection may be required:
Do not assume that one pad is sufficient for one complete hinge. Check the hinge certificate, doorset schedule or door manufacturer’s instructions before calculating the quantity.
Norseal publishes the graphite hinge-pad range for installation behind hinge blades on fire-resisting doorsets, with fire resistance referenced in accordance with BS 476-22.
The pad does not independently provide an FD30, FD60 or other fire-resistance classification. Performance depends on the complete assembly, including:
Whenever a hinge is removed or replaced on a fire-resisting door, the concealed intumescent protection should be inspected.
Replace the pad if it is:

The hinge pad is sold individually.
Calculate the quantity from:
Where the evidence requires pads behind both blades, order two pads per hinge.
Select this product only where the supporting evidence permits:
Do not substitute Interdens, a thicker graphite pad or a differently shaped pad without supporting evidence.
The NOR905 hinge pad must be installed in the position required by the hinge certificate, door manufacturer’s instructions or doorset assessment.
Before removing the hinge, establish whether the pad is required behind the door-leaf blade, the frame blade or both blades.
Confirm:
Do not select the pad solely because it appears to fit the hinge recess.
Support the door securely before loosening or removing a hinge.
Remove and refit one hinge at a time unless the applicable door-installation procedure requires another method.
Supporting the door helps prevent:
Remove the approved screws and carefully lift the relevant hinge blade from its recess.
Retain screws that remain suitable for reuse. Replace damaged fixings only with screws permitted by the hinge and doorset evidence.
Check that the recess is:
Do not deepen or enlarge the recess unless the resulting dimensions remain permitted by the doorset evidence.
Remove dust and loose fibres using a suitable brush or vacuum.
The receiving surface must be clean and dry before the self-adhesive pad is applied.
Do not install the pad over:
Position the pad within the hinge recess before removing the release liner.
Confirm that:
Do not trim or reshape the pad unless this is expressly permitted by the hinge or doorset evidence.
Remove the adhesive release liner without touching or contaminating the adhesive surface.
Align the pad carefully within the recess and press it firmly into place.
Ensure that:
Position the hinge blade directly over the installed pad and align it with the approved fixing holes.
Refit the specified screws progressively and evenly.
Confirm that:
The self-adhesive backing positions the pad. The hinge screws provide the structural fixing for the hinge.
Where the supporting evidence requires a pad behind both hinge blades, repeat the process behind the corresponding blade in the door leaf or frame.
Use one separate pad for each protected hinge blade.
Remove the temporary support and operate the door carefully.
Confirm that:
Verify that:
Inspect the hinges as part of the routine fire-door inspection programme.
Check for:
Whenever a hinge is removed or replaced, inspect and reinstate the specified intumescent protection before returning the door to service.
The NOR905 hinge pad does not independently provide a fire-resistance period.
Performance depends on the complete approved doorset, compatible hinge, correct pad material and thickness, protected hinge-blade locations, screw arrangement and installation quality.
