T E C H N I C A L A D V I C EFull technical back-up is all part of the Scotts service. This brochure covers some of the
more fr equently asked technical questions, but for mor e detaile d information or advice
concerning specific topics, please contact our technical team w ho will be happy to discuss
your requirements in full.
F O R E S T R Y P O L I C YIn compliance with our envir onmental policy, wherever possible all timber is sour ced from
forests managed on a sustainable yield basis.
H E A L T H & S A F E T YEvery possible pr ecaution is taken to ensur e that all pr oducts, and the pr ocesses of their
manufacture, meet with the r elevant health and safety guideline s. It is our aim to provide a
safe working environment for our employees and risk-fr ee products for our customers and
end-users.
Ideal for new-build or r efurbishment projects, flush doors ar ecreated to meet your exact specification. Our skilled technicalteam has the expertise to handle a range of r equirements andcan advise on any technical issue to ensur e that your doorsmeet your precise needs.
C O R EUsing either a solid particleboard or laminated timber core, all flush
doors are built to the highest industry standards. Both types of core
material are dense enough to accommodate standar d ironmongery
and both construction techniques have achieved a “Sever e Duty”
rating when tested in accor dance with BS DD171, thereby negating
the need for old-fashioned inter nal framing.
Internal Doors are generally supplied with particleboar d cores
External Doors will be provided with laminated timber cor es
L I P P I N G SDepending upon the required finish and application, lippings can
either be applied after the surface finish, giving a pr otective 10mm
border all r ound, or prior to surface finishes, pr oviding a con sistent
finish to the whole door face. Door to door meeting edges ar e
generally left squar e or slightly r ounded. Meeting stiles can b e
rebated if r equired, but this is not r ecommended for fir e doors .
Door/overpanel meeting edges ar e normally left squar e, but in t he
case of pairs a 12mm r ebate is incorporated as standar d to act as a
stop for the doors.
F A C I N G SParticleboard cor ed doors have a higher density outer skin to
which veneers and laminates can be applied dir ectly. This surfa ce
also pr ovides the ideal medium for painting without the need fo r
further facings.
Solid timber doors ar e manufactured with MDF facings for painti ng,
particleboard as a substrate for veneer and laminate, or WBP
plywood for exterior use.

Flush Doors
V E N E E R SUsing a selection of exotic and standar d veneers fr om ar ound th e
world, Scotts is able to pr ovide doors that will complement any
interior and match just about any design scheme.
From plain quarter-cut to highly figur ed crown-cut veneers the technical
team is always happy to advise on the ideal choice for your sch eme.
Glazing beads and edge lippings ar e carefully selected to match the
face veneer. Edge lippings ar e veneered over as standar d, but can be
left exposed to suit pr oject requirements. Where over-door panels are
required, veneers are laid to run thr ough, as shown above.
The use of moder n laser -cutting technology means that a huge
array of sophisticated patter ns and detailed mar quetry designs are
also now available, opening up a wealth of choice for designers
and architects.
L A M I N A T E SThe wide range of laminates available gives flexibility and cho ice to
the specifier. Sleek contemporary patter ns, wood grains, satura ted
colours, metallic finishes, and many mor e of fer a huge array of
possibilities. Hard wearing, durable and stable, laminates are suitable
for just about every application.
Glazing beads and lippings ar e individually chosen to complemen t
the specific laminate for each job. Lippings ar e generally appl ied
after the facings to pr otect the laminate edge.
F I N I S H E SVeneered doors ar e finished as standar d with two coats of semi-
matt, acid-catalysed lacquer. Alternative finishes such as stains, or
high gloss lacquers can be applied if specified. Paint grade doors are
normally supplied with one coat of white primer; but can be ful ly
finished with paint or tinted lacquer to any RAL or BS colour . All
doors are fully wrapped in corrugated car dboard to pr otect against
pre-installation damage.

B U I L D I N G R E G U L A T I O N SResistance to the passage of fir e is one of the most basic task s that
a door has to perform within the built environment. Where property
and escape r outes need pr otection, the specification of Scotts fire
doors ensur es compliance. The designation and position of fir e
doors within a building, ar e generally r ecommended by ApprovedDocument B (2000 edition) of the Building Regulations 1991.
Half hour and one hour fir e resistant doors have been successfu lly
tested in accor dance with BS 476 pt 22 , by UKAS accr edited test
stations. They are also covered by ‘Global Assessments’ extrapolated
from the test evidence, by UKAS accr edited laboratories – as
recommended in the 2002 Amendments to Appr ovedDocument B . Test evidence to BS 476 pt 8 , and BS EN 1634-1 is
also acceptable under the Building Regulations.
The stability of a fir e door is no longer a criterion of testin g, and fire
doors ar e now r eferred to only by their integrity r equirement e .g.
FD30, FD60.
G L A Z I N GIt is advisable that all V ision Panels are factory glazed, to e nsure that
the overall fir e rating of the door is not compr omised. It is e ssential
that beads of the correct section, material and density are used, and
that appr opriate intumescent materials – as tested – ar e corr ectly
applied. Pyr oshield Clear Safety (Georgian wir ed) glass is used as
standard for FD30 and FD60 applications but unwir ed, laminated,
and insulating glasses are available as required (see glass
performance table, page 5).
VISION PANELDIMENSIONS
In order to preserve the
performance standar d
and structural integrity
of a door , glazing
panels should be
designed within the
dimensional guidelines,
illustrated here.
S E A L S In the event of a fir e, intumescent (heat activated) seals ar e
required to seal the gaps ar ound door edges, preventing the
transfer of hot gasses, and to ‘clamp’ the door in position wit hin its
frame. It is important that the corr ect amount and type of
intumescent material is used in the corr ect position, as too mu ch
can be as detrimental as too little. It is normally pr eferable that
intumescent strips ar e incorporated within the door frame, and
where doors only ar e supplied, strips will be pr ovided for the
meeting edges of doors and panels only . If seals ar e r equired t o
door heads and hinge stiles, this should be clearly indicated.
Primed doors ar e pr ovided with white strips as standar d, while
veneered and solid timber doors are supplied with colour
co-ordinated ‘timber-grain’ strips.
Concealed strips ar e available for FD30 and FD60 applications b ut
this practice has been r endered virtually obsolete b y the requirement
for smoke seals in virtually all fire doors. It is now far more practical
and cost effective to use a combined intumescent and smoke seal .

C O R E M A T E R I A L SAll Scotts fire doors are manufactured using core materials approved
for use by BM TRADA Q-Mark , or CERTIFIRE third party
accreditation schemes.
F R A M E M A T E R I A L SIt is essential that the corr ect density, and section of frame material,
is used in conjunction with fir e doors, to avoid the invalidati on of
certification. It is ther efore best practice to have frames
manufactured by your door supplier . If this is not possible or
practical, the following guidelines should be followed when
specifying frames from an alternative source.
FD30 FRAMES
Frames for FD30 doors must have a minimum section of 32 x
70mm between the door edge and finished opening. If applicable,
minimum 12mm stops can be planted, or r ebated fr om the solid.
Frame material can be either har dwood, or softwood of minimum
density 450 kg/m 3, or MDF of minimum density 730 kg/m 3. Smaller
sections may be available but should not be specified without
checking with the Scotts technical team.
FD60 FRAMES
Frames for most FD60 doors must have a minimum section of
32 x 70mm between the door edge and finished opening. If
applicable, minimum 12mm stops can be planted, or r ebated from
the solid. Frame material should be har dwood of minimum density
640 kg/m3. Lesser density har dwood of a gr eater section may be
permissible; but clarification should be sought fr om Scotts tec hnical
team. For above average door sizes, a larger section may again be
necessary – please check.
I N S T A L L A T I O NAn incorrectly installed fire door is unlikely to perform as required in
a fir e situation, endangering pr operty and even lives. Every Sc otts
door or doorset is supplied with full instructions for corr ect
installation. Reference should also be made to British Standard Code
of Practice BS 8214:1990.

Performance DoorsPerformance doors ar e required to perform a variety of specialist functions within the builtenvironment. Hospitals, prisons, schools, banks and public acce ss buildings, for example, allmake different demands on internal and external doors. The more common types, includingsmoke resisting doors, acoustic doors and X-Ray r esisting doors , are detailed her e. Scotts ofThrapston can sour ce other performance doors for customers, to meet various specifications.Please contact the technical team for further information.
SPECIFICATION
A major consideration, when specifying acoustic doors, is the
relationship between the wall/partition and the door . If a soun d
attenuation of say , 36dB is r equired between r ooms, it is not
generally necessary to specify an expensive, special constructi on
Rw36dB door. Depending on the construction of the dividing wall ,
and the pr oportion of wall occupied by the door , a lower rated,
standard construction door can usually be specified. For instan ce, for
a typical door occupying 1⁄8 of the wall ar ea, the following
approximate combined door: wall values would be achieved:
For further details ask for a copy of our technical data sheet.
For typical sound reduction values of glazed panels see table p age 5.

TYPICAL ACOUSTIC SEAL DETAIL
A C O U S T I C D O O R SThe 2003 edition of Appr oved Document E (resistance to the
passage of sound) of the Building Regulations, r equires general ly
that doors should have a minimum mass per unit ar ea of 25km/m 2,
or a minimum sound r eduction index of Rw29dB. As indicated in
the specification guide (page 14), all Scotts standard flush doors will
exceed these values, when hung in a suitable frame with proprietary
seals corr ectly applied. T o ensur e their performance, it is
recommended that all sound impr oved doors ar e supplied as pr e-
hung doorsets.
Standard testing pr ocedures will measur e the ability of a door to
reduce a sound emission acr oss a variety of fr equencies. The
degree to which a door manages to r educe the sound, when tested
to BS EN ISO 140-3:1995 , and evaluated in accor dance with
BS EN ISO 717-1:1997 , is known as the weighted sound r eduction
index; expressed as an Rw:dB value.

SEALS
While typical values for similar constructions of door r emain f airly
constant, the choice and correct application of door edge sealing
systems is critical. Appr opriate seals will always be included with
Scotts sound improved doorsets.
S M O K E R E S I S T I N G D O O R SIn the event of a fir e, it is the inhalation of smoke – not inc ineration –
that causes the majority of personal injuries. Designing doors and
doorsets that r esist the passage of ambient temperatur e smoke i s an
important element of safe building design. Appendix B of Appr ovedDocument B of The Building Regulations r ecommends that when
tested in accor dance with BS 476: Section 3 1.1 at 25 Pa, smoke
control doors should have a leakage rate not exceeding 3m 3/m/hour
(measured at the head and jam bs only). Wher e smoke containment is
required, the suf fix ‘S’ is added to the designated fir e resistance; e.g.
FD30S, FD60S. As most fir e doors also r equire smoke control, wherever
intumescent strips ar e provided with fir e doors or frames, a co mbined
intumescent and smoke seal is supplied as standa rd.
If r eduction of smoke (draught, or
sound) leakage under the door is
required, the most practical solution
is a pr oprietary ‘dr op’ seal; such
as the Lorient IS8010 depicted
here. Such seals also over come
the problem of compliance with
BS 8214 and BS 5588 Part 11 ,
which recommend a maximum gap
of 3mm beneath a fir e door . This
can pr ove impractical wher e floor
finishes are uneven.

X - R A Y D O O R SLong experience of working dir ectly with hospitals and ar chitects
has enabled Scotts to develop X-ray doors for virtually every k ind of
specialist application. Critical in pr oviding appr opriate r esistance to
the passage of harmful X-rays, these doors incorporate a lead
membrane of a particular thickness, as designated by the Nation al
Radiological Pr otection Boar d, or an appointed Radiation
Protection Advisor.
By employing lead thr oughout the door leaf and frame section, a
continuous barrier acr oss the whole door opening is achieved.
Vision panels ar e also an option, with the use of a specially
designed x-ray glass with an inter nal transparent membrane.
When fitting ir onmongery, perforations of the lead membrane
should be avoided, and it is normally recommended that a
protective lead barrier is pr ovided around the lock/latch case.
X-Ray doorsets are provided as single pr e-hung sets only.

Panelled DoorsAs specialist joiners, with mor e than 85 years experience of pr oducing high quality pr oducts, Scotts is ideallyplaced to supply a wide range of traditional panelled doors. Panelled doors ar e generally manufactur ed inhardwood, and each one is individually cr eated to maintain high performance standar ds whilstpreserving the appearance and character you r equire.
D E S I G NThe choice of moulding pr ofiles and panel configurations is alm ost
limitless. Listed buildings and period pr operties often call fo r an
exact match to an existing beading pr ofile in or der to cr eate a
replacement door with the pr ecise look of the original. These d etails
can be specified at the time of or dering and our technical team will
be happy to advise on this matter .
C O N S T R U C T I O NTraditional construction techniques ar e used thr oughout; all ma in
joints are glued, and comprise a wedged, through-mortice and tenon,
whilst all rails, muntins and stiles ar e made fr om selected tim ber.
Panels can be either solid or glazed, with solid panels being f lat, or
raised and fielded according to requirement, and manufactured from
MDF, ply or solid timber to match the framework.
M A T E R I A L SHardwood is the usual material of choice. Not only does this pr ovide
structural integrity to the door , able to withstand the rigours of most
applications, but also har dwood can be car efully chosen to pr ovide
the desir ed look. Car efully selected har dwood can be used as th e
basis for a paint finish or , alternatively, clear lacquer can b e applied
to let the natural beauty of the grain become the main attracti on.
P A N E L C O N F I G U R A T I O N SThe most common panel configurations ar e two, four or six panel s
– as shown below – although virtually any combination is possib le,
including panels with curved framework, as per the example shown
above right.

F I R E - R AT E D P A N E L L E D D O O R SScotts is one of the few manufactur ers who can of fer a fire-resistant
panelled door , fully tested in accor dance with BS 476: Part 22 . Available with a FD30 rating, with anything fr om two to
ten glazed or solid panels, the exact design can be cr eated to suit
your application. As with the flush doors, frames, intumescent seals,
glazing and hinges ar e all available as part of a fully
certified package.
When designing, or specifying fir e rated panelled doors the fol lowing guidelines should be observed:
M O U L D I N G SThe profiles of the rails, muntins and stiles can be varied to taste,
with the ovolo or stepped ovolo being the two most widely used
types. However, it may be necessary to produce a simple square
shouldered frame and then apply the desir ed mouldings to
framework or panels afterwar ds. This latter method of construct ion
opens up a wide variety of choice which will fundamentally af fect
the way the finished door looks.
Standard sections are detailed below, although these can be varied
to suit particular design r equirements.
Careful selection of mouldings can make a door appear anything
from simple, classic and understated to bold, gener ous and lavi sh –
the choice is yours. For listed buildings or sensitive location s it is
possible to match a new door to an existing item by r ecreating the
exact profile of mouldings and beadings.
Some of the mor e common mouldings ar e shown below.

E X T E N S I O N L I N I N G SFor larger wall thicknesses (>170mm) an extension lining can be
supplied loose to tongue into r ebated frames, or linings. This
prevents the possibility of wide sections of timber curling in service.
F I R E R E S I S T A N C EWhere frames ar e for fir e doors, material of an appr opriate sec tion
and density will automatically be pr ovided, and frames will be
grooved and supplied with all necessary intumescent strips – se e
page 7; FD30 frames, FD60 frames.
P R E - D R I L L I N GThe pr e-drilling of fixing holes is not r ecommended, as experie nce
has shown that the positioning is often not compatible with wal l
conditions found on site.
S C R E E N SDoors and their frames ar e often incorporated within a larger g lazed
screen, to pr ovide either an inter nal glazed partition, or glaz ed
entrance door.
Beads are normally loose-pinned for site glazing, as dif ficulties can
be experienced on site when fixing pr e-glazed screens.
Jambs and heads of scr eens will normally be 32mm thick, with
mullions, transoms and cill members being 44mm.
To ensure compliance with Part N of the Building Regulations,
and for general safety, it i s recommended that class A, B or C safety
glass to BS 6206:1981 is used in all glazed items – see glass
specification chart page 5.
Frames Manufactured in har dwood, softwood or MDF , all frames ar e purpo se made, and can be pr oduced to anypracticable design. Frames are supplied ready primed, or sealed as standard but can be stained, or fullyfinished if required. We would recommend, however, that frames ar e finished after fixing.
The most commonly specified door f rame sections are detailed below:
LINING
Economical option, with stops
supplied loose, for site adjustment.
REBATED
One-piece frame, with glued and
screwed mortice and tenon joint.
SPLIT
Integral architrave frame, with a
continuous plywood tongue; easily
installed over wall finishes. Can
accommodate deviations in wall
thickness.
ARCHITRAVE
Supplied loose to match the frame
finish. 45 x 15mm supplied as a
standard but can be manufactur ed to
any practical section.
45 x 26mm architrave can be tongued
into the lining or frame to take up
deviations in wall thickness.

B E N E F I T S• Tolerances and clearance gaps are pre-set in the factory. No site
adjustments are necessary
• Materials are supplied from a single source
• The risk of damage is reduced as doorsets can be fitted at a l ater stage in
the contract (after the wet trades)
• The moisture content of both door and frame is contr olled, reducing the
risk of differential shrinkage
• Doors can be simply lifted out of the frame, and stood aside w hilst
frames are fixed
• Colour and grain of timber for door and frame can be more closely
controlled
• Costly site labour is reduced
• The risk of performance being compromised by inexperienced site
labour is greatly reduced.
Both flush and panelled doors can be pr ovided as pre-hung doorsets,
with few limitations on the design of frame, or ar chitrave. Typical
doorset co-ordinating dimensions are as follows:
Specifying fully-finished, pre-hung doorsets has been shown to be the most cost-ef fective andefficient method of pr ocuring doors for virtually any pr oject.
H I N G E SDoors will normally be hung on maintenance-fr ee Royde and T ucker
Hi-Load 101 lift-off hinges. These ar e supplied in a bright zin c plated
finish as a standar d but alternative finishes and types ar e available to
suit specific pr oject requirements. If r equired, doors can be h ung on
free-issue hinges.
O T H E R I R O N M O N G E R YIronmongery is generally r egarded as a specific design featur e and is
therefore normally specified as a separate package for fixing on site.
If r equired, however , doors can be fitted with flush ir onmongery
items (such as flush bolts, or lock/latch cases) in our factory .
Ironmongery for fir e-rated doors will only be fitted if it is o f an
appropriate design, with specific test evidence. Exter nal entra nce
doors can be supplied fully furnished with all ironmongery items
including: multipoint espagnolette locks, security hinge-bolts and
handles – please consult our technical team for further details .
