PuraSoundFor projects where sound attenuation is a priority, such as hotel rooms.

Our PuraSound timber doorsets use a variety of cores, seals and glazing types to achieve dB ratings from 29dB up to 55dB. 
Our PuraSound timber doorsets use a variety of cores, seals and glazing types to achieve dB ratings from 29dB up to 55dB. Automatic drop seals are installed into the bottom of doors and concealed from view. These seals have added benefits in reducing draughts, light penetration and odour circulation.

Acoustic perimeter seals are often combined with intumescent strips when the door is also a fire door, although surface fit options are available if preferred. Glazing can be incorporated into doors or adjoining screens.

Our most popular dB rated doorsets as follows: 

29-32dB: 44mm door, with appropriate drop seal and perimeter seals. 
34dB: 54mm door, with appropriate drop seal and perimeter seals. 
40dB: 54mm door, with specialist acoustic core construction and seals. 
43dB: 58mm door, with specialist acoustic core construction and seals. 
45dB: 65mm door, with solid perimeter door frame. 
50db: 70mm door, with solid perimeter door frame. 
55dB 85mm door, with solid perimeter door frame. 

Certification specific to your project can be provided on request.

Doorsets are manufactured to exceptional accuracy, using CNC machinery, to fit their intended aperture. This reduces finishing work needed on site and speeds up installation time.

A variety of framing options is available. Sections of the most popular options are shown below although bespoke options are available.

We can supply matching skirting or, at the other end of the scale, we also have frameless options. 

Frames can be supplied assembled or flat-packed. They can be sent with the door pre-hung in them or separately in advance to support site schedules. 

Frame options

Frame materials

Mid-range option for internal doors. It is our most popular option for painted doors, although it can be stained or lacquered. Suitable for fire-rated and acoustic doorsets.

Excellent for durability and security. A variety of species is available. We recommend lacquer or stain to allow the beauty of the wood to be seen. Suitable for fire-rated, acoustic and secure doorsets.

A cost-effective solution providing a smooth surface that gives the best finish for painted doors. It can also be veneer-wrapped. Suitable for fire-rated doors.

Steel frames are available for any door and supplied with hardware or factory-prepared for it

All our timber is FSC certified. If required, please ask for chain of custody certification when requesting a quote. 
Vision panels and side/over screens can help to increase visibility, distribute light and enhance design. In certain locations, such as entrances, they are a legal requirement with defined minimum sizes (see below).

Some of our most popular vision panel styles are shown here but we can make panels to any size and shape. For fire and sound-rated doors there may be some restrictions but we will guide you through the requirements to make sure these are maintained.



Bespoke panels over or to the side of a door can be seamlessly integrated. They may be filled with glass or designer panels to complement styling of the door or room. We will advise on how to incorporate these to maintain dB ratings.

Glass Types 

Laminated: two sheets of glass with a PVB (non-fire-rated) or intumescent layer in the middle. May crack under pressure but mostly sticks to the central layer and remains in one piece.
Tempered: Heat-treated to give resistance to impact; where breakage does occur it shatters into tiny pieces.


Fire ratings

Glass fire ratings are available as follows:

Glass finishes

Glass can be supplied with a variety of finishes. Combinations of these finishes can be used, for example to offer privacy in lower panels and visibility in higher panels:



Where privacy is required we offer a range of choices. We recommend these options but can incorporate alternatives as required.


Vision panels in entrance doors 

These are governed by the Government’s Building Regulations parts M (Access to buildings) and K (Protection from falling, collision and impact). This diagram shows the minimum requirements for vision panels in entrance doors.


There are two main types of beading for vision panels: bolection and flush. Beading is supplied in hardwood species, with finish to complement the door, or laminated for fully encapsulated doors. Examples here are shown as for an FD60 door, with intumescent strips between the beading and the glass.


Doors can be finished to suit your requirements and we can support you in the co-ordination of finishes across your whole project. Some of our most popular options are shown below and we can source many others. For a true representation of colour or finish, please ask us for a sample.

Paint and lacquer finishes

Timber doors can be supplied unfinished, lacquered, primed or spray-finished. Finish sheens from 5% dead matt to 90% high-build gloss can be achieved. We can match any RAL colour, contact us for samples. Among our most popular finishes are grey oak and painted white wood.

Wood species

The most common species are shown here but others can be sourced – ask us for any special requirements.
QTD = Quarter Cut, CR = Crown Cut


Veneer cuts

The most popular cuts are crown and quarter, although rift and rotary are also frequently chosen. Unusual cuts are also available, including figured quarter, bird’s eye, burr and fiddleback quartered. Contact us to find out what cuts are available for your preferred species. 

Popular cuts:


Designer cuts:



Veneers can be matched in different ways to achieve a variety of effects as shown below. 

Book match: veneers are mirrored to give a symmetrical effect
Quarter: veneers are mirrored and turned to give an effect radiating from a central point
Slip: leaves are laid side by side to give a gradually-varying repeat pattern


Special finishes

Woods can have additional treatments applied to them for cosmetic or performance purposes. These samples show the impact of treatment on a standard oak veneer. For a true representation, please ask us for a sample.

High gloss: can be combined with (as here) or without stain to give a stunning designer gloss to the wood
Polyurethane coated: a durable coating that protects the wood while allowing the natural grain to shine through
Smoking: retains the wood’s natural beauty but darkens it and brings out deeper tints
Staining: adds depth or colour to the wood, while retaining the visibility of the natural grain


Grooves and inlays 

For an extra designer touch, doors may be grooved or have colour-matched inlays.


A durable, scratch- and damage-resistant alternative to wood in high-traffic areas where impact is likely. 

Depending on the location and purpose of the door, variable laminate coverage may be desired. Dorplan can meet any requirement from part-faced to full encapsulation.
We use a range of laminate suppliers, including Formica and Egger, who between them offer almost every colour, pattern and texture. 

The range of laminate options available is so extensive that the only limit is your imagination. Designs are complemented by textures to achieve an authentic feel to the materials represented. Shown below are just a few of the myriad choices available: (images courtesy of Egger) 

Wood effect: a huge selection of timber types is available. This is supported by a range of wood grain textures that can be matched to timber types to give a natural feel. 


Colour: A rainbow of colours can be used to complement any scheme in hues from subtle pastels to vibrant primary colours.

Many other finishes are available, including industrial, geological and metallic effects, and textiles or patterns. They can be enhanced with textures that complement the design and add authenticity to the finish.


Note that we do not recommend highly-textured surfaces in hygiene settings.
