Flush Doors

Ideal for new-build or r efurbishment pr ojects, flush doors ar e created to meet your exact specification. Our skilled technical team has the expertise to handle a range of r equirements and can advise on any technical issue to ensur e that your doors meet your pr ecise needs.

LAMINATED TIMBER CORE SOLID PARTICLEBOARD CORE

Solid timber lamels

Particleboard (average 650Kgm ) -3

CORE Using either a solid particleboard or laminated timber core, all flush doors are built to the highest industry standards. Both types of core material ar e dense enough to accommodate standar d ir onmongery 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.

Veneer

Plastic laminate

Internal Doors are generally supplied with particleboar d cores External Doors will be pr ovided with laminated timber cor es

L I P P I NG S Depending 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 NG S Particleboard 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.

L A M I NA T E S The 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.

V E NE E R S Using 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 c an be left exposed to suit pr oject requirements. Where over-door panels are required, veneers ar e 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.

F I NI S H E S Veneered doors ar e finished as standar d with two coats of semimatt, 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 agai nst pre-installation damage.

Fire Doors G L A Z I NG It is advisable that all V ision Panels ar e 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).

MAXIMUM GLAZED AREAS

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.

Resistance 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 Approved Document B (2000 edition) of the Building Regulations 1991. Half hour and one hour fir e r esistant 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 oved Document B . Test evidence to BS 476 pt 8 , and BS EN 1634-1 is also acceptable under the Building Regulations.

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 ef fective to use a combined intumescent and smoke seal .

The stability of a fir e door is no longer a criterion of testin g, and fir e doors ar e now r eferred to only by their integrity r equirement e .g. FD30, FD60.

D I M E NS I O NS The following table gives an indication of the maximum dimensions of fir e door that can be specified fr om the Scotts range – examples given ar e for LATCHED, SIN GLEACTING doors. For UNLATCHED, or DOUBLE-ACTING doors reduce dimensions by appr ox. 10%. For doors with OVERPANELS - reduce dimensions by approx. 10%.

CORE MATERIALS

TYPICAL INTUMESCENT DETAILS

All Scotts fir e doors ar e manufactured using cor e materials app roved for use by BM TRADA Q-Mark , or CERTIFIRE third party accreditation schemes.

FD30

FRAME MATERIALS It 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 fr om an alter native 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.

Overpanel

FD60 FRAMES

Door

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 fr om 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 â&#x20AC;&#x201C; please check.

Performance Doors Performance doors ar e r equired to perform a variety of specialist functions within the built environment. Hospitals, prisons, schools, banks and public acce ss buildings, for example, all make different demands on internal and external doors. The more common types, including smoke r esisting doors, acoustic doors and X-Ray r esisting doors , ar e detailed her e. Scotts of Thrapston can sour ce other performance doors for customers, to meet various specifications. Please contact the technical team for further information.

SMOKE RESISTING DOORS In 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 oved Document B of The Building Regulations r ecommends that when tested in accor dance with BS 476: Section 3 1.1 at 25 Pa, smoke 3 control doors should have a leakage rate not exceeding 3m /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 r esistance; 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.

TYPICAL ACOUSTIC SEAL DETAIL

Lorient IS8010

Floor Lorient LP1004TS

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.

Lorient IS1212

Lorient LP1004TS

ACOUSTIC DOORS The 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 ehung 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 impr oved doorsets.

Lorient IS1212

Lorient IS8010

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 1 ⁄ 8 of the wall ar a typical door occupying ea, the following approximate combined door: wall values would be achieved:

Panelled Doors As specialist joiners, with mor e than 85 years experience of pr oducing high quality pr oducts, Scotts is ideally placed to supply a wide range of traditional panelled doors. Panelled doors ar e generally manufactur ed in hardwood, and each one is individually cr eated to maintain high performance standar ds whilst preserving the appearance and character you r equire.

DESIGN The 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 NS T R U C T I O N Traditional 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 AT E R I A L S

PAN EL CON FIGURATION S The most common panel configurations ar e two, four or six panel s â&#x20AC;&#x201C; as shown below â&#x20AC;&#x201C; although virtually any combination is possib le, including panels with curved framework, as per the example shown above right.

Hardwood 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 , alter natively, clear lacquer can b e applied to let the natural beauty of the grain become the main attracti on.

Some of the mor e common mouldings ar e shown below.

M O U L D I NG S The pr ofiles 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.

• Tolerances and clearance gaps are pre-set in the factory. No site adjustments are necessary

Doors will normally be hung on maintenance-fr ee Royde and T ucker Hi-Load 101 lift-of f hinges. These ar e supplied in a bright zin c plated finish as a standar d but alter native finishes and types ar e available to suit specific pr oject requirements. If r equired, doors can be h ung on free-issue hinges.

• Materials are supplied from a single source • The risk of damage is r educed 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 compr omised by inexperienced site labour is greatly reduced.

OTHER IRONMONGERY Ironmongery 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 .

Both flush and panelled doors can be pr ovided as pr e-hung doorsets, with few limitations on the design of frame, or ar chitrave. T ypical doorset co-ordinating dimensions ar e as follows:

Specifying FLUSH DOORS

PAN ELLED DOORS

To assist with the specification of doors and doorsets, the fol lowing is intended for guidance in compiling an NBS type specification.

The wide variety of types and styles of panelled door available , means that accurate specification is essential. In the case of panelled doors particularly , an elevation of the r equired door style is often necessary. The following guide is intended to assist with the specification of panelled doors, to ensur e that your r equirement is correctly interpreted, for both pricing and manufacturing purpo ses.

Where a particular performance r equirement, such as FD30 or Rw33dB, is identified, appr opriate perimeter seals and glazing systems – as tested, will automatically be included. There is no need to identify them separately.
