|Q What to think about before buying a door?
There are a number of points you should consider before you purchase a
new door, either for yourself, or if you are fitting it for a customer.
Choose a design that suits the house style:
On this website there are many designs of doors; ranging from the
traditional designs to the more modern ones. There is also a choice of glass
designs available, and our glazed doors are not offered with glass packs, so
there is no need for glazing.
Ensure that you have made a note of the appropriate measurements:
The height, width and depth of the frame are important, but decide by
measuring, whether the frame is square and true. This will allow you to
estimate how complex the fitting task will be. Buy a door that is either the
right size or slightly too big.
Check both the frame and threshold for signs of wear or damage and ensure
the frame is secure to the wall.
Decide your budget
We know, from the wide number of doors we offer that you will find a door
to suit your budget.
Questions you should ask before finally selecting your door
Is it guaranteed?
Goods supplied by Emerald Doors Ltd are guaranteed from defects in
manufacture for twelve months from the date of receipt, any claims against
extended warranties offered by our suppliers must be taken up with them
directly, Emerald Doors Ltd will supply contact details, but will not be
liable or become involved with any such claims. The Warranty supplied with
your product applies to goods installed on UK Mainland only. Warranties
apply to goods or product which have been treated/decorated and installed in
accordance with the manufacturers and our instructions
Are the doors you wish to purchase constructed using the best methods
Here are some points you should look out for:
External doors should either be jointed using traditional mortice and
tenon joints or dowel joints coupled with modern adhesives. All our doors
are. To ensure strength and stability make sure that the mid rails of the
door are at least 150mm wide.
Make sure you know exactly what tolerances the door will give you if you
have to trim – you must be able to take 12mm from each side of the door
without affecting its structural integrity.
Make sure that the panels are fully weatherproofed.
Ensure when buying pine doors that you ensure that the joints are jointed
and glued using modern adhesives and that the doors are suitable for either
stain or paint, you will find that all the pine doors in this catalogue are
constructed to the highest standard.
Can you ensure a consistent look throughout your house?
We offer a complete family of doors that are matched in design. Please
refer to our products range menu and select the door you are interested in
and you will be given a list of ‘related products’ which will enable you to
create your family of doors.
Should I book a joiner before my doors are delivered ?
ABSOLUTELY NOT Always wait until your door/s is delivered before
arranging a joiner. We have great faith in our distributors, but doors are
not an easy thing to transport and complications on delivery may occur.
Especially on special order items where in rare cases, problems in supply
may mean the original lead time is reinstated.
Is the glass in the door toughened for safety ?
All the glass in our doors (with the exception of our traditional leaded
light designs) is rated to BS6206, the standard for toughened glass in the
Safety Glass (Excerpt from BSI website) The Kitemark scheme for safety
glass is changing to reflect the recently published European standards EN
12600, EN 12150 and EN ISO 12543. It is likely that BS EN 12600 will replace
BS 6206 in the UK Building Regulations later this year. Therefore we have
decided to use this as the primary standard for the Kitemark scheme for
safety glass. Bringing these requirements into the Kitemark scheme, we will
ensure that you have the required technical evidence to support the
necessary compliance with the Construction Products Directive in addition to
compliance with UK Building Regulations.
The main difference in testing is in the size of the sample and the
• BS 6206 requires the impact test to be performed on a 1930mm x 865mm
sample using an impactor bag.
• BS EN 12600 requires a sample size of 1938mm x 876mm and the use of a
‘twin tyre’ impactor.
Are you offered comprehensive instructions in how best to fit and finish
We have reprinted some excellent advice from the British Woodworking
Federation along with advice from our experienced technical people on how to
ensure that your door when fitted is finished to the highest standard.

CARE OF TIMBER DOORS ON SITE
2. Delivery and Storage
Doors and doorsets manufactured by members of the British Woodworking
Federation are designed and manufactured using the best available techniques
to produce performance rated components. After delivery it is vital that
doors are correctly treated to ensure that the moisture content is
appropriate for the situation and that they are not physically damaged in
unloading, storage and installation. Good practice avoids damage, maintains
quality and saves money.
Internal and external doors and doorsets may be supplied 'in the white',
with a primer or stain base coatapplied or as fully finished components.
Each type needs careful handling and protection although the actual
requirements vary slightly.
DELIVERY & STORAGE
CHECK DOORS AT THE TIME OF DELIVERY
All components should be checked at the time of delivery to ensure that
they are in accordance with the
order schedule, the delivery is complete and that the components,
including any protective packaging, are not damaged.
Timber used in the manufacturer of doors will be graded in accordance
with BS EN 942:1996 Timber in joinery - “General classification of timber
quality” and the workmanship will meet the requirements of BS 1186 Part
2:1998 “Timber for and workmanship in joinery” - Specification for
workmanship. The moisture content of timber in the doors should be in the
range of 10% and 16% depending upon their type and location.
BWF Guide No 11
For long term performance of the door and finish, it is important that
the appropriate moisture content is maintained during storage on site and
during the construction process. Wherever possible the sequence of
deliveries should be co-ordinated to site requirements in order that doors
are not kept on site unfixed for longer than necessary.
HANDLE DOORS CAREFULLY
Doors and doorsets should be handled carefully to avoid physical damage
(do not lift by glazing bars) and to keep them clean. When door leaves are
protected by shrink- wrapping or other packaging this should be kept in
place as long as possible. Doors delivered in the white should be sealed and
primed on all faces and edges immediately after delivery.
Never hang a door before applying a protective coating.
STORE DOORS UNDER COVER IN A DRY VENTILATED BUILDING
Doors should be stored flat (never on edge or on end) on a level surface
and kept clear of the floor on at least three level bearers. The bearers
should be longer than the width of the doors and the gap beneath the doors
should be at least 90mm.
Doors should be protected from dirt and damage but without restricting
air circulation. Natural finish doors should be stacked so that they are not
partly exposed to daylight and opaque wrappings must not be torn.
Exposure to ultra violet light can cause fading or discoloration of
timber and veneers. Whenever possible store doors and doorsets in the
sequence they will be needed with codes or identifying marks visible to
avoid double handling. Avoid dragging them across each other in the stack.
Doorsets which have projecting sills or have the hardware fitted must
have spacers between them in the stack to avoid damage.
BWF Guide No 11
PROTECT DOORS DURING SITE OPERATIONS
Ensure that the moisture content of the wood is kept close to the level
at which it was when the door was manufactured.
Internal doors must be conditioned to the service conditions before
They must be protected from abnormal heat, extreme dryness, humid
conditions or sudden changes of temperature or humidity.
Doors should not be stored or fitted in the building until the wet trades
are finished and the building has dried out.
TREAT PREFINISHED DOORS LIKE A PIECE OF FITTED FURNITURE
Factory finished door frames or door linings should ideally be fitted
into pre-formed openings and not built into masonry walls.
Pre-finished doors should retain their protective packaging until the
latest possible time, ideally until
after internal decorations have been completed. If it is necessary to
separate the doors from doorsets each door and frame should be given an
identification mark so that the correct door is returned to the frame.
DOORS SHOULD BE FITTED SQUARE
Doors should be fitted square, true and plumb and fixed in accordance
with the manufacturer's instructions or the project specification. Three
hinges should be fitted to all external doors, doors weighing more than 20
kilogrammes and internal doors where large differences of temperature or
humidity on opposing faces can be expected (e.g. bathrooms and airing
BWF Guide No 11
Ideally, external door frames should be set well back from the outer face
of the wall or else be protected by a canopy. If not, the head of the frame
should be provided with a projecting head drip. External doors opening
outwards should be particularly well protected.
MORTICES FOR LOCKS MUST NOT BE CUT THROUGH JOINTS IN THE DOOR FRAMING
Cutting through joints in the door framing will impair performance of the
rail joint. If any part of a previously treated external door or door frame
is cut or drilled, swab the newly exposed timber with a suitable organic
solvent preservative treatment and re-coat with primer or stain.
USE GOOD GLAZING PRACTICE
Glazing rebates and backs of beads should be sealed with an appropriate
Glazing panels in doors must satisfy the requirements in respect of
Bead glazing must be correctly fitted using compound or glazing tapes to
both sides of the glass.
FIRE RESISTING DOORS SHOULD NOT BE ALTERED ON SITE
Fire resisting doors and doorsets need special consideration when
fitting. Use BWF-CERTIFIRE doors and follow the manufacturers instructions.
Most of our external doors and frames are sold unfinished, meaning that they need to be stained, varnished or painted after purchase. It is vital that the door or frame is sealed properly in ADVANCE of installation. If you fit the door unfinished and it is subjected to rain or direct sunlight, the door will be ruined.Refer to the instruction leaflet enclosed with your door for finishing confirmation. Try to use a branded well known finishing product. We recommend Sikkens or Sadolin.Use as many coats as the manufacturer recommends but to check that you have done finished the door correctly, spray a little water on the door and see that the water forms beads and runs off. If it doesn’t then apply another coat or two. Don’t forget to seal the areas that you can’t see such as the tops and bottoms and inside lock and letterbox cut-outs.
Finish your door BEFORE it is fitted, including Top & Bottom edges
Do not use a water based finish
Do not use a penetrating finish such as Danish/Tung-oil
Use a flexible finish that will allow the timber to expand & contract
If in doubt please contact the sales team before carrying out any work
Many of our internal doors are sold unfinished too. These need to be sealed straight away to stop the timber drying out and splitting or taking in moisture that is in the air. It is just as important to seal the tops and bottoms when fitting doors internally. Our manufacturers don’t accept Waxing or Oiling a door as appropriate methods of sealing so we cannot provide a guarantee for any door which has been treated in this way. The only exceptions are the Period Reproduction Range which are veneered in Rustic Oak, are supplied untreated and which may be waxed or oiled without compromising the standard 12 month guarantee.
More and more doors are being supplied ‘fully finished’. Remember, if you’ve bought a door that is sold under this heading, you must re-seal any trimmed edges, cavities or cut-outs straight away. The top and bottom of the door are often overlooked but must be done, even if it involves taking the door down for a short while. This is particularly important for sealing the end grain which acts like a sponge and soaks up any moisture, causing a door to swell and split. Equally, egress of moisture can cause timber to crack/split and bow.
ENSURE SURFACES AND EDGES ARE IN GOOD ORDER BEFORE APPLYING FINISHING
If the primer or base coat stain has deteriorated, or the surface has
been exposed to light for longer than three months, it should be re-coated
before further finishing coats are applied.
BWF Guide No 11
Finishing of external doors and frames should be carried out in dry
weather using only good exterior quality materials in accordance with the
On external doors, the finish should be an exterior quality paint or a
'high build' stain. ('Low build' types of stain should not be used on
external doors.) It should be noted that the use of dark coloured paint or
stain finishes on external doors, particularly if located on the south or
south west elevations of buildings, will result in high surface temperatures
on the door and can increase the risk of distortion and of resin exudation
through the finish.
ENSURE ALL SURFACES AND EDGES ARE PAINTED
It is important that all surfaces of doors are painted. For external
doors or other doors subject to wetting or take up of moisture it is
especially important that the full finishing system is applied to the top
and bottom edges of the door leaf. The bottom edge should be coated before
fitting the door. Factory finished doors should be checked for damage to the
finish and any small areas made good in accordance with the manufacturer's
recommendations. The door manufacturer may disclaim responsibility for any
defect or failure that may subsequently occur which is attributable to
non-compliance either wholly or in part with the advice given in this
information sheet Further advice is available on Moulded Skin Doors in BWF
Guide No 9 – Moulded Skin Wood Fibre Doors - December 1998.

Q Are my doors solid ? What is Engineered Construction ?
||The majority of our doors are engineered. It is quite regular practice for doors to be made from engineered components. This means that doors with a face of pine, ash, oak or walnut often use a veneer over a composite solid core. Applying doors with a real wood veneer provides greater uniformity in colour and enhances the appearance of the door. It also gives the door greater stability and less chance of twisting or splitting. One other benefit is that it is much better for the environment
