Fire Door Blank (60min)
Specication & Finishing Information
MAKING SPACE MORE VALUABLE
Product Specication
The core of this product is laminated hardwood lamels faced with exterior grade hardwood plywood making it suit-
able for external and internal applications.
Size adjustment: Leaves may be reduced in height and width without restriction, but reduction in height must be
from the bottom edge only and the top rail must be preserved at its required dimension.
Glazing
Up to 0.4m2 of glazing is approved per leaf in Sentry 60 single and double door applications.
Partial or complete interruption of the mid rail is permitted. Apertures must not be less than 100mm from any door
edge. Multiple apertures are acceptable up to the maximum approved area with a minimum dimension of 80mm
between apertures.
Installation must be in accordance with the glass/glazing system manufacturer’s recommendations.
Approved glasses are:
6/7mm Pyroshield - Pilkington Glass Ltd, 6mm Pyran S - Schott Glass Ltd.
Alternative glass products may be used, providing relevant evidence generated in suitable timber door constructions
can be provided.
Approved proprietary glazing systems are:
ISL Therm-A-Glaze 60, Sealmaster Fireglaze 60, Lorient System 63 & 90+, Pyroglaze 60 (Mann McGowan Ltd)
Door frames
Hardwood is approved of minimum density 640kg/m3 and of a minimum section of 80mm x 40mm after rebating
or proling. Single acting doorframes must incorporate a 12mm rebated or planted stop.
Intumescent materials: Palusol 100 series PVC encapsulated intumescent is approved in appropriate sections to
correspond to the required leaf sizes and congurations as shown below.
Note that intumescent seals may be tted to the door edges or frames.
Door edge lippings & gaps
The minimum lipping specications are as follows:
Square: 6mm thick Rounded - 10mm rounded with maximum 4mm proling
Hardwood lippings with a minimum density of 650 kg/m3 are required to all 4 edges.
Glue lines should be UF, Cascamite or P.U. adhesives.
Door gaps: Door edge gaps should be controlled to replicate those used in testing. As a general guideline, gaps
should not exceed 4mm.
The door edge gap at the threshold can be increased to 10mm to allow for oor coverings.
Fixing / Sealing to Structural openings:
The supporting construction must be capable of staying in place and intact for the full period of re resistance
required from the door set.
Fixing and sealing the frame against the structural opening is an important factor in the re resistance performance
of re resisting door sets. The frame jambs should be xed to the supporting construction using steel xings at
500mm maximum centres, preferably adjacent to all hinge positions. Fixings must be of the appropriate type and
must penetrate to a minimum depth of 50mm. Whilst the frame head does not require xing, packers must be
inserted. Guidance for various methods of sealing the frame to structural openings is provided in BS8214:2008
“Code of Practice for Fire Door Assemblies with Non-Metallic Leaves” which should be referred to where
appropriate.
