D O O R SThe specialist door manufacturing division pr oduces doors to suit just about any

specification – from basic paint-grade flush doors for of fice refurbishments, through to the

high quality, veneered or traditional panelled doors for commer cial and residential

applications. By har nessing the latest in computer -controlled manufacturing machinery ,

together with the skill of craftsmen, Scotts can handle a wide range of door r equirements

and joinery projects from its own purpose-built factory .

Q U A L I T YThe tradition of quality is central to the company’ s ethos. By conforming to Scotts

in-house quality assurance systems every pr oject meets the agr eed specification – first time,

every time.

Unrivalled Quality and ServiceScotts started pr oducing specialist timber pr oducts in 1920. Th e company wasfounded on the principle of always putting quality first and since then it has gonefrom strength to strength to become a leader in its field. T oday, more than 85 yearslater, the family owned company is widely r ecognised as one of the country’ sforemost suppliers of doors and specialist timber pr oducts.

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.

F L U S H P A N E L L E D D O O R SA practical and cost effective way of producing panelled doors, and

FD60 panelled doors in particular , is cr eating them using a flu sh

door base. For har dwood doors, veneers can be laid up in ‘stile s

and rails’, and carried over the edge lippings, as 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 .
