EDSL Acoustic doors, offer a wide range of doors with excellent soundproof features; we design, manufacture and install doors throughout the UK. Our acoustic doors are tested to ISO standards, and achieve an average level of sound reductions up to 44dB (decibels). However the industry is always testing new products to try and further increase this sound reduction within a timber door.
Our acoustic doors are suitable for a wide range of projects including schools, hospitals, factories, airports, theatres, hotels and heavy engineering operations. Working alongside industry leaders enables us to offer you a comprehensive range of doors to suite every acoustic need and budget. Manufacturing our own doors, within our factory, allows us to add excellent soundproofing features; such as seals around the frame to stop sound penetrating around the door, drop-seals to the bottom of the doors and fantastic vision panels with excellent acoustic properties which also allow light through. Having the flexibility to manufacturer in house is one of the many reasons we are one of the UK's leaders in the door industry.
The purpose of an acoustic door is to prevent noise escaping from a room or for noise getting into a room. A common mistake is to specify the same decibel rating to a doorset as that required in a party wall (i.e. breezeblock or brick cavity) exemptions exist for this and the average of the whole area of the wall is taken with the doorset as a proportion.
The acoustic performance of a doorset can be influenced by:
20RwdB: Normal speech is easily overheard.
25RwdB: Loud speech is clearly overheard.
30RwdB: Loud speech is clearly audible.
33RwdB: Some loud speech audible - normal speech inaudible.
35RwdB: Loud speech audible but not understandable.
45RwdB: Loud speech heard faintly.
50RwdB: Shouting will be barely audible.
Rw: – The “weighted Sound Reduction Index” is a number used to rate the effectiveness of a soundproofing system or material. It expresses the difference between the sound intensity hitting one side of a structure and the resulting sound measured on the other side. Therefore, the higher the Rw number, the better a sound insulator it will be.
dB: – The Decibel (abbreviated as dB) is the unit used to measure the intensity of sound, It is a unit expressing the ratio between power and intensity. Normal conversation is at about 60 dB, a lawnmower at about 90 dB and a rock concert at about 120 dB.
EDSL are proud to be part of the BM TRADA Q-Mark Fire Door Scheme.
This fully comprehensive UKAS accredited certification scheme for fire doors ensures that our performance and production facilities are regularly checked through audit testing and factory inspections.
Fire Door Manufacturers have a legal requirement to demonstrate their doors will resist the spread of fire. The BM TRADA Q-Mark Fire Door Scheme has been designed and setup to allow all fire door manufacturers to demonstrate that their doors meet the industry standard requirements. All of our fire door sets and frames are custom designed to meet your specific requirements, available in a range of finishes to meet your preference, these can also certified to FD30, FD60, FD90 and FD120. For further customisation, our doors can also incorporate any of our standard or bespoke glazed vision panel sets; providing a range of styles and finishes are perfect for use within areas such as residential properties, offices and hospitals.
Being part of this scheme allows EDSL to demonstrate consistent quality, ensure on-going compliance, maximize our products service life and provide peace of mind through independent verification by a third-party certification body.
Fire proof doors have two primary functions when fire breaks out, the first function is to contain flames and smoke to allow safe passage away from the building. This acts as a barrier and isolates the fire away from the area of escape, allowing the recommended amount of time given the distance of the exit point. The second main feature is to delay the spread of flames and smoke, depending on the specific requirement for the particular part of the building they operate within determines the relevant rating required.
We are the preferred and trusted supplier to many large construction companies, as well as direct suppliers to architects and interior designers; our commitment and quality to the development of fire doors gives these household construction names the peace of mind they require. Our work ethic separates us apart from the competition, as we constantly strive to improve service, value engineering and research into fire resistant door technology, which we are extremely proud of; all of which adds to our vast manufacturing experience and excellent range of fire resistant doors.

These principles have been proven to achieve a reduction of crime risk by up to 75%, by combining minimum standards of physical security and well tested components. With our experience in architectural ironmongery, we are able to install custom security features that suit your specific requirements.
As expert manufacturers, we are able to adapt our security doors to cost effectively meet our customers requirements. The types of security doors we supply are single and double, door and screen combinations, communal with access control, fire exit and flat entrance doors. To meet fire safety regulations, all of these can be NFR, FD30s or FD60s, creating a fire resistance to the appropriate standard. For those areas that require considerations towards soundproofing, we are able to manufacture our doors with acoustic properties, dramatically reducing sound reverberation.
A poorly manufactured, or installed, frame may compromise the integrity and, more importantly, the security of a door. We design and manufacture our frames to protect, eliminating weaknesses in the structure and potential areas where the door could be pried open; further increasing the effectiveness of the doors manufactured with security in mind.
EDSL can offer a wide range of finishes to our hardwoods and veneers from Stains, Lacquers, Oils, Primed or Painted Topcoats. In addition, we can offer varying sheen levels from a matt to high gloss.
EDSL, provide a wide choice of hardwood options, coupled with an attractive range of veneer finishes, which are all suitable for general usage. Select a frame of either softwood or hardwood, which can be factory primed for painting completion on site. Alternatively, you may wish to opt for a factory finished hardwood.
Our Joinery Doorsets can be supplied with solid timber rails and stiles with the architraves and frames supplied in primed softwood or MDF for site painting, or a factory finished hardwood to match the door.
Our doors are manufactured with a hardwood crown cut veneer, offering a superior finish. All of the crown cut veneers in this range are book-matched to provide an attractive and carefully balanced pattern across the full door. To achieve this excellent finish, we take successive leaves of veneer and create a mirrored effect by reversing each alternative leaf and aligning corresponding edges.
To complete your door, we fit a fully factory finished matching hardwood over veneered or exposed lipping and a matching glazing bead to suit.

Bespoke joinery products and timber doorsets are delivered to site ready for installation. However, in order for this to be completed satisfactory, it is important that certain handling, storage, finishing and installation requirements are met. For best performance and to ensure that your guarantee is not invalidated, the following guidelines must be fully observed.
Our guidelines outline the procedures that must take place in accordance with guidance offered by BS 8000 Part 5 : 1990. Covering details on the conditions in which our doors must be stored to reduce the risk of damage; resulting in potentially damaging the aesthetics and the functionality of the door.
A timber door must not be exposed to extreme temperature or humidity prior to unpacking. Packaging and protective wrapping should not be removed until the products need to be installed. Doors must be stored flat in a dry, well ventilated environment. Stack doors on at least three level bearers equally spaced along the length of the door. Under no circumstances should they be stored in damp or freshly plastered rooms.
Installation of doorsets should be in accordance with the guidelines within of BS 8000 Part 5 : 1990. Ensure the property where the doors are to be hung is completely dry, particularly freshly plastered rooms. Install fire doors in accordance with the installation instructions attached to the door edge. Do not cut apertures on site as this will invalidate the fire rating.
Correct installation of the door frame will not only maintain the structural integrity in a fire situation, but will also assist in the prevention of a twist, wane and cupping of the frame due to changes in humidity and natural timber moisture movement. Our guideline contains details and diagrams on how this should take place.
The decorative finish applied to external joinery must be maintained in service and moisture must not be allowed to penetrate into the timber throughout its life.
Annual inspections should be made and touching up carried out as necessary in areas of wear on external doors. Regular inspections should be carried out to ensure that doors are operating correctly and not binding on floors or against the lock keep, as this will cause damage to the door. It is particularly important to check that intumescent / smoke strips are undamaged.

SOLID TIMBER CORE
A core constructed with solid wood, either one block or several pieces, that is used to act as a base for veneers, panels and mouldings which creates the visual aspects of a door. This is achieved by laminating the timber together for an increase of stability and strength, this core offers a heavier sturdy design that provides sound reduction and better insulation than other cores.
STABLE DOOR
A door capable of opening and closing as two halves, this is intended to allow you to open the top half whilst keeping the bottom half closed.
STAINED DOOR
Stains allow a door's natural grain to be complimented in a variety of ways whether it be by adding a distinctive colour or affecting the lightness of the wood's shade. These often provide a door with additional protective properties too such as UV protection.
