Door Types

BI-FOLD DOORS:
Bi-Fold doors are designed to fold within the frame opening. They can be fitted to open to the left or right. There is no track to the floor just a pivot hinge which is anchored to the frame. The ordering size refers to the frame opening rather than the actual height of the door is reduced to allow for the track. The doors can be trimmed up to 6mm from each edge if required.



CONCERTINA DOORS:
A door that does not open outwards or inwards by a hinge but rather folds vertically in one or more places, giving the appearance of a concertina. A concertina door can be divided up into any number of vertical subdivisions, depending on the width of the door and the application. 


DOWEL CONSTRUCTION DOORS
Both internal and external doors can be jointed in this way. Several dowels are used to connect one piece of timber to another eg rails to stiles in a traditional panelled door. This method is ideal for today’s modern engineered doors which use a variety of core materials in construction.


FIRE DOORS:
This type door is constructed with a fire-resistant core material and certified in accordance with BS476 Part 22: 1987  to hold back fire for  either 30minutes or 60 minutes. These doors are thicker and heavier than standard internal doors and will be required to be fitted with fire rated door furniture as well as intumescent sealing strip. You should seek advice before trimming these doors as it could affect the fire resistance of the door.


FRENCH DOORS:
These doors are available in pairs with rebated meeting edges (stiles) and are most often used for between internal rooms and to outside areas such as patios. They are sold in Engineered hardwood and oak as well as traditional softwood (hemlock). Hardwood and oak pairs can be supplied ready glazed generally single glazed with clear bevelled toughened glass, or unglazed for site glazing (either single or double) .Hardwood doors will take a paint or stain finish but should only be fitted in non-exposed locations.


FLUSH DOORS

These doors are flat both sides and can be constructed with various core materials with veneered facings. The quality of the core and frame construction as well as the type and thickness of veneer used will determine weight and final price of the door. 


PANELLED DOORS

This traditional constructed door is constructed with an outer frame (stiles and cross rails) and either flat or raised panels inserted to form the design. Panelled door designs are often referred to depending on the number of panels they have, hence 6 panel and 4 panel are the most common.


ROOM DIVIDERS
: 
A room divider is an internal pair of doors or set of doors and sidelights, between two rooms or inner porch door. 


SIDE LIGHTS: 
A side light is a window at the side of a door frame, it can be directly glazed or a matching door  insert can be bought subject to overall size requirements and availability. Sidelight frame kits are supplied flat pack and can be assembled to form a single or double sidelight.  


SLIDING DOORS: 
Most doors can be fitted to sliding door gear which is designed to take the door along the outside of the opening. Pocket sliding doors open into a cavity within the wall.


STABLE DOORS: 
A stable door comes in two halves, meaning the opening and closing can be split between the top and bottom of the door. They are available in Harwood, Oak ,and Pine as well as composite .They can be fitted so as the top half opens out or in when a new frame is fitted.


COMPOSITE DOORS
:
 
A composite is a mixture of component materials which complement each other to create a strong building material. Composite doors usually consist of a solid timber or particle board core, a wooden frame and an outer skin of GRP (Glass Reinforced Plastic). The advantages of composite doors are that they are durable, good value and relatively maintenance free. 


HARDWOOD DOORS: 
Hardwood doors are produced from far eastern hardwood timber which comes from a variety of deciduous trees. These trees tend to grow more slowly therefore producing denser wood for a strong, sturdy and durable door.
 

KNOTTY PINE DOORS: 
This well known softwood is a great value timber primarily used for its decorative qualities. The dark knots residing in the grain give the wood a distinctive rustic appearance. 


LEDGED & BRACED DOORS: 
A ledged and braced door features horizontal timber ledges across the door with additional timber braces which span diagonally between the ledges. Frame ledged and braced doors are generally vertically boarded on one side and sometimes include an external frame for added strength and stability. They are available in pine as well as oak and are ideal for a cottage look.


MORTISE & TENON DOORS: 
Doors constructed with Mortise and Tenon joints are considered more durable than dowel jointed doors and therefore are ideal for external locations. The joint is created by forming a tongue from the cross rails and fitting this into a slot in the stile with glue and then driving in wedges from the outside to secure the joint.


MOULDED DOORS
:
 
Moulded doors are timber frames with a one-piece moulded door facing commonly made from MDF or hardboards. This hard-wearing "skin" can be either textured with a wood grain effect or smooth. They are supplied primed only in various shades of white and off white finishes.


PITCH PINE DOORS
:
 
Pitch pine is a resinous softwood timber with an orange, reddish brown hue. It is one of the strongest softwoods and is used mostly as a domestic timber making it ideal for internal doors where a stripped pine effect is required. The pitch pine tree is fast growing and reseeds itself very quickly, so is more environmentally friendly.


PRE-FINISHED DOORS: 
Pre-finished doors have been factory treated during manufacturing so that they are ready for a hassle free installation once delivered. Finishes include varnish, stain, lacquer or paint. Exterior pre-finished doors vary slightly to interior finished doors as they need to be water repellent and weather resistant to preserve and protect the door from the elements. 



SEMI SOLID CORE DOORS: 
A "heavier feel" door with a semi solid core which is more than 50% solid wood with some hollow areas. These doors generally offer a longer life than a conventional hollow core door. 


VENEER DOORS: 
Wood veneers are thin segments of timber or paper used to give your door a more attractive, real wood appearance. Veneer products are less expensive than solid wood products but still retain the popular natural wood finish.



ENGINEERED DOORS
: 
Most modern mass-produced doors are made using solid strips or blocks of timber which are glued together or with some internet doors laminated board or particle board.  They are then faced with a decorative veneer of varying thickness and material.  Some are then lipped with a thick matching piece of wood.

  • No warping, twisting, splitting or shrinkage
  • More consistent panel matching
  • Matching fire doors
  • Eco friendly over 70% of door from formed timber


PART L DOORS
:
 
This is a section of the building regulations relating to conservation of fuel and power and this is where thermal insulation requirements of buildings, and in particular doors, are covered.

Compliance is generally required for new build but there are some refurbishment projects which may fall within the scope of the requirements.
